Hyperactive fan

The fan on my PB G4 (a little over 1 year old) has been a little hyperactive over the past 3 weeks or so. After I startup my computer (from sleep mode) and work on it for a little while, the fan will turn on and stay on for a few minutes (maybe 2-5?), and then turn off. This repeats several times within 2 hours of computer use. Sure, I run multiple apps simultaneously, but nothing that requires a significant amount of memory. My computer sits on a desk, and the air temperature in my room is about 25 degrees C.
In addition, about 4-5 times within the past 3 weeks, my fan has made an unusual, loud, eerie noise. It's almost like a lower pitched and slightly calmer noise of a power saw... kind of like the fan blade is scratching/striking something in its path. The fan turns on, then the eerie noise starts and lasts about 10 seconds, then the noise stops while the fan keeps going, then the fan stops a few minutes later.
I DO live in a relatively dusty area, and I haven't cleaned my computer since I got here 3 months ago (I've decided to get a can of compressed air ASAP). Is this just a dust problem? Or should I get my computer checked out by a service/repair center?
Thanks!

There is one way you can sort it if it sounds like it is rubbing something. But do not try it if, you are't very good inside computers, or, if it tis still under warrenty.
It is possibel to go inside the powerbook and replace the fans if they are faulty or perhaps dust them out, shift some loose wires etc. But as I said is is not easy and will void your warrenty.
Try PB fixit for guides.
I would try compressed air aswel.
Hope it helps!

Problems with second hard drive

I bought my PowerMac G5 new in 2005 and about two years after I got it, I installed a second internal hard drive. I didn't have any problems with the drive until about six months ago (which was when I moved, but I'm not sure if that has anything to do with it). Around that point, I started hearing a single, loud click followed by a slight winding down noise. Then, my computer would almost completely freeze. After a few moments, I would hear a bunch of soft clicks and my computer would go back to normal. I figured that it was a problem with one of the hard drives, but I wasn't sure what to do.
Later on, the problem got more severe, lasting more like 30 seconds. When my second drive unmounted during one of these episodes, I shut my computer down, opened the case, took both plugs out of the second hard drive, put them back in, and started up my computer again. After that, my computer was running great again. But, a few weeks later, the symptoms started up again.
So, I've gone through the same cable un-plug and re-plug process whenever the drive unmounts. Sometimes it helps and sometimes it doesn't seem to help at all. Altogether, I think that the second drive has unmounted about five or six times. I haven't had this problem at all with the original hard drive and I haven't noticed any other problems with my computer. (Well, okay, there's the rare occasion when, instead of going to sleep, it turns the screen black and puts the fans on full blast.)
Could the drive itself be going bad and it has nothing to do with the cables? I have a utility installed that always monitors the SMART status and it hasn't reported any problems. Are there any other troubleshooting steps I should take? Any advice would be appreciated. Thanks!

Before I bought DiskWarrior, I thought I'd try some troubleshooting with the software I have on hand. But while I was doing that, the problem got worse. Now, I'm having major problems just getting the computer to boot. I'll give you the rundown on what's happened. It goes through a few boneheaded twists and turns and goes on at great length, but I thought I'd relate it all in the hopes that someone can see a likely pattern.
My first thought was the Apple hardware test, which I had thought was on the Mac OS 10.5 install DVD. So naturally, I didn't see the hardware test listed under Utilities. But while I had it up, I used Disk Utility to do repairs on both hard drives (checking both the disk and permissions). It found no problems on the 2nd hard drive, but found a few errors with "leaves" on the booting drive. It also found a bunch of issues with the permissions, but I don't think it was anything out of the ordinary.
Just for the heck of it, I asked it to run the repairs again. Not long into that, I got what I think is a kernel panic (overlaid message saying I needed to restart my computer in a few languages). It also sped up the fans.
I pushed the power button to shut it down, then started it up again. I heard the startup chime, then nothing but a black screen and the ol' hyperactive fans. I went through that several times before I was finally able to boot from the DVD again. Then, I changed the startup disk back to my usual boot volume and restarted. I had to go through the black screen and insane fans several more times before I could boot normally.
Next, I thought I'd try OnyX to see what it could do. Which might not be much, but I had it repair the disks again and also had it run the daily, weekly, and monthly maintenance scripts.
I checked into the black screen & hyperactive fans booting problem elsewhere in the forums, and saw that it was recommended to run the Apple hardware test and also found the correct procedure for doing so, which was to insert the PowerMac G5 install disc (not the Mac OS X upgrade DVD) and press Option when booting. I loaded the disc, restarted, and held down the Option key, but before I could get anything to actually load, I had several more sessions with the black screen of fans.
Regarding that boot problem, I've sometimes seen the red light inside the case turn on almost immediately after I turn on the computer. Other times, it will not light up by itself. But, when I hold the power button in to shut it down, the red light briefly turns on before the unit shuts down. I've also noticed that the light on the Caps Lock button is coming on and staying on when I'm trying to start the computer.
So, after several tries, I checked my G5 User's Guide and it said to disconnect any external devices before trying the hardware test. I had a USB thumb drive plugged in and a FireWire drive hooked up for Time Machine backups, so I took both of them out. Once again, I tried starting up with Option held down and this time, it worked. The fans started running at full blast after I selected the hardware test, which I hoped was normal. So, I asked it to run the extended test and it found no problems. I restarted my computer without reconnecting anything and, at least for now, it's working normally.
Any new thoughts?

Fan sounds like a hairdryer after screen has been replaced...eh?

Can someone who's 'up' on imacs give me a steer here.
At the beginning of the week, with only a 14 days to go on my 3 year Applecare warranty, I noticed a grey streaky 'misting' on the screen when it was turned off. It was really quite bad. Called Applecare, who got their servicing company to collect it, screen replaced with no problems. Got it back today, new screen, looks great.
So far so good. Except that the fan is now whirling around and making an incredible noise after about 10 minutes of the machine being turned on. I'd say it's around 5 times as loud (or hyperactive) as it was before I sent it off for a new screen. One of the things I turned to the imac for was it's quietness, so this is worse for me than a misty screen, to be honest. Sounds like a hairdryer.
Put it this way: I often listen to music late at night, very low, but now the fan would drown out the sound of the music. Called Applecare, who are going to get it collected again, but from what I've read in these forums this evening (& I'm no expert) it could be a software related problem (temperature controls and all that...) I'm not sure that the guy I was talking to at Applecare today quite understood what I was trying to explain, and said it was definitely a hardware problem. I want to call Applecare back on Monday before the mac's collected again to just make sure it has to be carted off again, with a bit of back up info from anybody who might help here.
thanks
chris

Reset your SMC to see if that makes a difference:
Shut down the computer.
Unplug the computer's power cord.
Wait fifteen seconds.
Attach the computer's power cord.
Wait five seconds, then press the power button to turn on the computer.

There is a fan problem on the Air!

I have had a MBA since day one and no matter what anybody says I am convinced there is a problem with the fans on this product.
I am sitting in a hotel, doing nothing more than reading emails and surfing the net (no youtube) and the fans are going crazy.
I have tried all sorts of things including all the software I am sure will be suggested here but nothing really works.
My Mac can be quiet for hours and then out of the blue (like now) the fans come on at 6900rpm.
This is buggy and it need to be fixed. I've paid enough for it.

I also find the fans somewhat irritating and unpredictable. One thing I have noticed: the fan reaction is much delayed. You do something that increases cpu load (say watching a web page with heavy flash) for a short time. Then maybe 10 minutes later the fans pick up, and it then takes 10 minutes to cool down again. The fans on my MacBook can also be hyperactive (disclosure: my previous PC laptop did not even have a fan, so I'm spoiled), but the reaction is predictable. If I watch a web page with heavy flash, the fans will kick up, but as soon as I close it, the fans will settle down again.

Fan Error on X201

I bought my X201 (3249CTO) last october from lenovo's website. 2 weeks ago, my laptop became unable to boot up except showing "Fan Error" message. Before that, my laptop sometimes suddenly shut down(directly to dark screen) with no reason.
The Warranty is going to expire tonight. I still can not find the entry to report this error and ask for repair on this lenovo's official website. Most links I've seen are "check....", "check...", or "extend or upgrade"... and some software solutions. I can not find any tech support email. When I go to the "CONTACT" page, most contact info is about sale, business. After I click, click and click, I found that "800-xxxxxxx" tech support number. Following the instructions, I press 1, 1, 1... and hearing a lot of electric voice"please go to www.lenovo.com.....", I heard that their manual service was only available during 8a - 8p Mon - Fri. While I'm most on class during that time. Why don't they have an email for warranty service?
How can I contact them to return my laptop back and get repaired?

@LilHayah,
You would need to call the tech support via the number 800-xxxxxx then they would advice you on how to get the laptop shipped back for service or if you have a onsite service.
There are no emails for tech support.

Month Owned MSI GE60 Apache Pro Fan Issues

Hi everyone,
I have had my MSI GE60 Apachce Pro 15" laptop for a little over a month now.
For the first month, I could barely hear the fans when leaving the laptop idle or using non-power hungry applications that do not involve gaming, such as browsing the web or watching videos. Now, however, the fan seems to always be running at a medium intensity, even when idle. As soon as I boot up the laptop, the fan is much more noisy than it used to be and stays that way.
The program HWinfo64 shows my CPU temperature at usually 41 degrees Celsius. Moreover, turning on the Cooler Blaster feature does not decrease the advertised 5-10% temperatures either. In fact, it increases the heat to around 42-43 degrees Celsius.
My desk is usually completely dust free, so I do not think dust is the issue here. I will have to open up the back to be completely sure, but I do not want to void my warranty for something as silly as cleaning it out (There is a void sticker right above one of the necessary screws to remove the back casing. I will contact MSI to inquire about this because I read that MSI will allow owners to remove this sticker in certain locations without voiding the warranty).
Could there be any other reason besides dust that could make my fans this noisy? Does anyone have suggestions on improving it? Thank you.

Try to remove battery and hold power button for 5 sec.
I tried that a few times, but it did not work. The fan noise is becoming unbearable tbh. Considering selling it now :/

MSI K7N2 Delta-ILSR Noisy Northbridge fan

Hi
I'm having a problem with the nforce chipset fan on my K7N2 Delta-ILSR.
It makes a horrible wailing sound when cold booting and is only running at about 2500rpm instead of 4000rpm.
It does this usually for about 30 seconds then runs normally.
Does it just need cleaning or is it on it's way out?
Any help would be greatly appreciated.
Thanks
Garfy

Hi,
I had the same problem. All I did was loosened the left screw(when looking from the front of the case) until the noise stopped. Give it a try!!!

MSI K7N2 Delta ILSR - Noisy Grinding Motherboard Fan

Hi,
The Motherboard Fan on my MSI K7N2 Delta ILSR has started to make a terrible grinding noise and I was hoping someone could offer some help on how to replace it.
Some of the questions I have are -
+ Is the Motherboard Fan screwed on or glued on?
+ Could I replace it with a suitable heatsink (no fan)?*
+ If it is glued on, what is the best way to remove it?
+ If it is glued on, could I just unplug it and stick a new fan on top of the existing one?
+ Has anyone else had this problem and if so what did you do to fix it?
* I was looking at a Zalman Motherboard Heatsink from http://www.quietpc.com/uk/vgamb.php
Thanks in advance, Jason.

Design Flaw in Twin Frozr fans

So, I'm finally creating a thread about this.
There's been reports over the last few years about fans making rattling noises, grinding noises, high pitched whines, whether on cold boot, idle, high RPM, or constantly, and quite frankly I'm tired of MSI ignoring the issue.
There is a design flaw with the Twin Frozr fans.
MSI needs to publicly acknowledge this.
Currently, the only way to get a replacement fan is to send your ENTIRE card in for repair. Other more reputable companies will send you out an entirely new fansink attachment at no cost. As one poster said it; "That would be like sending my car to Nissan every time I blow a tire"
My personal experience with Twin Frozr started with Twin Frozr 2 on my GTX 460 Hawks. The Talon Attack edition started to make a bad grinding noise on cold boot or if it actually got cold enough during idle operation. When the card warmed up, the noise stopped. Speeding up the fan to 100% sometimes also caused it to get rid of the noise, but that was only temporary unless the card stayed warm.
My non-hawk exhibited rattling as well, but to a lesser extent. No grinding noise on cold boot, just a low rattling.
My next card was a GTX 670 PE with Twin Frozr 4. Surely they fixed the issue by now right? Wrong! Within 30 days I started having fan issues. This fan doesn't rattle, but there is a high pitched whine when the fan is in operation. The faster the RPM, the louder the whine. Most people don't even know they have this issue because of the subtle tone of the whine and it being muffled by the fan's air sound at higher RPMs.
That's 3 separate graphics cards all exhibiting an issue with their fans.
There's one thing in common with these issues; it's only caused by the fan closest to the I/O. This boggles my mind. Surely if there was a problem with the fan design itself it would affect both fans, right? I just don't understand it. This leads me to believe it's a design flaw with the Twin Frozr design.
Some people seem to have an issue with the other fan, but it appears to be rare and not the same type of problem the majority of people are reporting.
Seeing as they want you to lose your card (and $10+ to ship it) for weeks at a time to 'fix' an issue which will no doubt happen again, something needs to be done about this. Their 'warranty' policy for this issue is completely unacceptable, as is the fact that the fans start acting up within a month of ownership.

I don't think we have a MSI office in Portugal, most brands don't.
Some stores are not reliable they buy from EU retailers some even from Asia retailers and usually they don't give proper support. In Lisbon you have stores like Globaldata, Nanochip, Chiptek and AquaPC they are in business for years, have good customer support and have also good prices.
I'm probably not going to buy any MSI product from now on , for obvious reasons.
Trying to contact a support shoudn't be this hard from a client , at this point I assume anyone that's doesn't want to lose time will just give up.
As a consumer I was forced to RUN and TRY to find msi support , MSI support mail doesn't event exist , since I made this thread it still hasn't been changed.
I really liked MSI ( I still have my 875P MSI neo here with my p4 and the NX6800 working ) it's like saying goodbye to an old friend that has been by my side since P4 times.
I'll buy msi products in US , or in another country maybe , but never MORE in portugal.
This is not cause of the shops , I recommend everyone to buy in the shops listed !!
In fact most of the portuguese shops tried to help me find msi support ( even though they weren't the stored that sold me the card ).
I really don't want ppl to get this mixed up, the problem here is MSI not acknowledging a problem that is simple to fix, having a non-existant email on their webpage as support for over 4 months and the fact that as a consumer I was forced to jump trough loops to actually contact MSI itself !
Every portuguese shop I contacted was super nice and really helpful pointing me to the new msi email
And actually the fix ( hot needle fix forum post link ) came from a shop reply.
US support was always super nice and helpful !
I was forced to fix my fan with the help of users.
If right now my MSI gpu is working is thanks to guru3d and hardwareoc and simillar forums ( thanks to everyone that posted Twin Frozn fixes , this may not mean much , but really .. thanks for helping me out ! )
MSI didn't help or even try to help me , I had to go out of my way to get help , and I never did.
I know some of those stores , they have great prices , but if I buy anything in portugal I'll buy other brands for obvious reasons. ( it was actually one of those shops that helped me pinpoint the "real" msi email )
I am a customer , I should be treated as such , I was joked and pushed around emails , found emails that don't even exist , I was ignored and left looking at a card going dead.
Maybe for some of you it's easy , you just buy another one .... and maybe that's the custommer MSI wants. But that's not me.
Pointing me to places to buy MORE is almost insulting at this point. I wont buy more ... I would be stupid of I did.
I just hope some other person that has MSI and is having this problem with Twin Frozn fans ( that msi refuses to acknowledge as THEIR problem !! ) can fix them themselves or take some info from my posts and others to at least understand what is happening.
From my pov , the fan eventually has some sort of lubrication problem , and due to that it starts to wobble , after that the coils heat up to a point it wobbles even more.
Due to the high temps the fan either "looses" enough to dump all the lubing out.
At some point the fan will heat up so much the plastic IS REALLY hot to the touch and fells that it can be actually moldable ( so I assume this is really bad )
This leads to the start-stop problem , the fan tries to kick itself on , but just makes things worse.
This leads to a fan that fails in 2-3 years.
MSI should either had a way to put oil in the fan OR just start to be ready to replace them.
The fact that IS an ebay market for Twin Frzn fans is just flabbergasting .
I wish I had a better view on this , but seriously looking at this thread, and seeing all the steps I have done , to find there are others like me that have a failing fan and that the ones that aren't ignored like me have to RMA a card for a simple fan doesn't give me any sort of confidence in this brand.
MSI has one of the best gpu coolers , honestly it's so god that after all this mess I stand as a testimony for it being one of the BEST gpu coolers around ! All my MSI products so far have been great ... but this experience was just ... weird ..
I wish MSI would contact the ppl that are in my position and help them , it's just a fan , it's an easy fix and it's easy to replace.
There are lots of ppl right now with fans starting to fail , just take their card , replace the fan and send them back , and MSI will have happy customers , HAPPY cause the brand CARED !
I'm only 1 client , MSI hardly "fells" me leaving ... I really like MSI ... so I wish this won't ever happen again to no one !
I have been ignored in mailing for TDR problems , after that about the 12h+ card artifacting being fixed with cold boot ( I assume this was an nvidia problem )
After using certain drivers that didn't TDR my card ( I have enough PSU for it so ... it's not the PSU ) and having been 2 years finding my own "solutions" to problems ... being ignored and just struggling to get help from MSI for a stupid FAN a cheap part and being hard just to contact them to get no answer .... and getting help from other users while MSI ignores me ? ... I'm thinking on leaving the brand ...
The fans are now working 100% , I'll post info when and if they fail ( if I see my "fix" stopped working ) .
It has now been a long time since 2011 and my first reports , and its been almost 6 months since I contacted msi about the portuguese email listed not existing.
The email is still there , that non-existent email is STILL listen in MSI website RIGHT NOW after me being emailing them about it for 4+ months ,as a customer, I can only assume they either ignore people , or they have a terrible communications internally .
Again after all this mess , I would be kinda stupid to support or try to buy another product from this brand , MSI support was always great and was the main reason I bought msi products, all this posts are from a person that was truly SHOCKED in everything that is happening and the feeling that no one cared.

MBP fans @ 6000 rmp when charging

The fans of my 2yr old mac have been going nuts lately (high 5000s/6000s rpm) so after looking into it with iStats I was led to change the battery (last one was health @36% w 157 cycles). Things are now great in terms of not having to keep the laptop plugged 24/7 but the fans still accelerate.
Both fans hover at about 6000 rpm when the cpu is plugged and yes, it does get a very hot on the bottom (laptop kept on solid desk surface only). It doesn't matter what I am running or not running on it at that time. If not plugged- mid 3500s. As soon as I plug it in- bam 6000 rpms, when I unplug back down to the 3000s rpm... the number of programs is irrelevant, and according to the application monitor nothing is "stealing" power so to speak.
I use the laptop a lot and have no other problems with it, but I do need to plug it - I am on it at about 8 hrs a day easily and with a new schedule on the way I plan on being on it even longer. Runs smoothly. I am just worried because I read somewhere that if it fans get over 6500rmp it supposedly would crash. The noise is not pleasant, I am used to my silent mac, but I'll buy earplugs if I have to so long as I don't have to part with it.
What is going? Please, please help.

MBP won't wake, is REALLY HOT, fans going full blast

This morning I made sure when I closed the lid on my MacBook Pro, that it went to sleep (pulsing sleep light). I found that this doesn't always happen right away, unlike the old Powerbooks. I then put it into my laptop bag, confident that it was fully hibernating.
When I arrived at work and pulled the MBP out of the bag, the sleep light was solid white, the laptop was really hot on all sides, and the fans were running hard. I opened the lid and there was no display, although I knew it wasn't sleeping because I could hit "caps lock" and it would toggle on/off. Apparently it had awaked while in my bag for some reason. The only way I could regain control was to hold down the power button and start from a "cold" boot. When I logged back in I could not find anything odd in /var/log/system.log during the time before the reboot.
My Energy Saver settings for "battery" mode are set to "Better Battery Life" so theoretically nothing should be able to externally wake the MBP. Bluetooth is Off. I have no idea then what caused it to wake up and flip out. This is the second time this has happened and I've been wary of its sleep behavior. Is there an updated SMC firmware for the 17" model yet?
This is really worrying because I could have left it in my bag for a lot longer and who knows, maybe it would have caught fire!

It happened again. I did a hard shutdown to keep it from really geting hot. After the boot, I checked the system.log. At the time which I suspect the interrupted sleep occured I saw this, which seemed to repeat a few times:

There is some indication that Bluetooth is involved (I could be wrong) but I know my Bluetooth is Off (icon is dimmed) and it is set to NOT wake the computer.

Can anyone recommend me a Northbridge fan replacement?

I have a MSI K8N Neo4-F nForce4 and recently i have been experiencing random crashes and lock ups which i think are due to the northbridge fan failing (it was making horrible noises).
I tried to replace this with the Asaka heatsink/fan combination thing but it didn't fit under the graphics card as there is only about 1.5cm vertical space available. Can anyone recommend a replacement suitable for this motherboard? Preferably a cheap one. =)
Also -i don't know much about chipset- is it safe to run the computer without a northbridge fan installed assuming i don't do anything intensive like games or whatever?
Thanks in advance.

I was sniffing around some other forums,(as you do), when I came across this post. It sounds intresting, and may be worth giving it a try.

"Repair your noisy cpu and system fans
This is a fix that will last for a long, long time.
Buy some graphite powder and some oil at an auto or hardware store. They come in different packages. For oil, the best is the pen-type as they are easy to handle and only give a small amount at a time. Just about any oil in a pen format will work fine. The graphite powder comes in small plastic tubes. But make sure you get graphite powder, not graphite oil, its too thin for this job! So you need graphite powder in a small tube and oil in a round "pen" that can be squeezed out and placed just where you need it. Also, when the oil is used up in the "pen" you can open it and add your own oil.
First, clean the fan blades off real well. If you have a heatsink with the fan then clean the heatsink off as well. You can even use a bit of your oil and some q-tips for cleaning if needed. Then, take the small circle, it usually has a name on it, but its in the middle of the fan. Peel one edge up carefully and put a very small amount of oil in where you lifted the label up. Now add some graphite powder in the same place where you put the oil, add as much or a bit more of the graphite powder than the oil. Clean off excess oil and graphite and push the label back where it was. You may need a very small amount of duct tape to hold the label in position and to prevent leakage. This is important if the fan is going to "sit up" as opposed to lying flat.
Now put the fan back where you want it and when it starts spinning it may be noisy for a few seconds until the graphite\oil works its way in. Then it will stop and it will stay stopped for many years and you may very well not need to buy a new fan after all!
I experimented a lot with this and this is the very best way to quiet all those fans and have them work well. I have always been a big fan of those removable ide hard drive trays that you can buy. But the fans are the pits, they get noisy real fast. So i had to find a way to fix them as they are very expensive and hard to replace. Now i don't have to. Combo of oil and graphite is the very best, by far. One caution, graphite stains worse than
oil, so be careful! I'm talking about staining your clothes and hands.
You can use this system with all CPU fans, video card fans, system fans, and even fans inside power supplies. But one word of caution, its easy to open a power supply and take out the fan, but do be careful as there are voltages there can can hurt you badly. If you don't know what you are doing then wear rubber gloves to get the fan out and to put the fan back in after the
repair!
Trust me, this will work. If the fan spins my method will work for years and I have even fixed fans that were stuck and wouldn't spin! This is better done with the fan on the table but in those cases where you cant or don't want
to take the fan out of the system, that's where the "pen" with the needle comes in again, but i still find a way to get some graphite in as well, graphite is what makes the oil last a long time! And graphite is also an oil, but you need both together for maximum effectiveness. Oil by itself will only last a few weeks or so and then evaporate, and the fan will get noisy again. Its the graphite powder that does the long term job. The oil really only helps to spread the graphite powder around really well so the graphite can do the job!
Hope you do as well as i have with this info!"
End Quote.
Edit - Additional Info
The type of northbridge fan used on some MSI boards, eg K8N Platinum & Diamond etc, require that you remove the fan from the board first (you will have to remove the motherboard to do this). This is because the top of the shroud is attached from the bottom by two tiny Phillips type screws. Once you have removed the shroud, very gently prise off the fan from the motor assembly. There is no need to try and remove the three other tiny screws that secure the fan motor in place to the bottom half of the shroud. Once removed, you will see that under the fan is a small plastic pin that holds the sleeve bearing in place.

[865PE/G Neo2 Series] Suggestions for excellent Air/Fan Cooling - P4 Northwood

Guys, I need some advice here. I've got my 2.8 Northwood up to 3.16 (yea, I know, not great or anything but good enough for right now).
Anyway, with the coming of the blazing Summer temps hitting Michigan in the high 80-90s, my case and CPU temps are skyrocketing. I am finding that my idle temps, once at 31C are now at 35-36C, and the CPU temps once at 42C max under load are now reaching 50+ C. Also, this is the first time in months upon seemingly endless months that I am now getting random reboots, and I am sure it is due to soaring temps and heat problems. The room temps here are killer, and right now are in the high 70s...
I would like to please hear your suggestions/recommendations on a good AIR/FAN cooling solution for my specs I have listed below. I am looking for something that is not very loud if possible, I welcome and thank you for your comments!

I only know that I can't suggest a HS and fan because my temperature is higher than my 2.6GHz Northwood's since i decided to install the Thermalright XP90 and the 92mm UFO Thermaltake fan(~82CFM max.). I recently discovered an old picture from Speedfan saying CPU temp: 40C!!! Now right after boot up, I get 40-44C idle and it can climb up to 60C at full load. I know for a fact that air flow is bad inside the case but it's unbelievable to have 40C+ idle. It can't possibly be the air flow so soon after boot. The pressure (and contact) on the CPU was enough to actually see my CPU stuck on the base of the HS after removing the HS!!! A few pins had to be straightened too.
So, from my experience I think you already rock, since we have 30C(86F) already where I live. The feeling of the XP90 crashed under my boot will ease my pain...Oh, yes it will.
P.S. I 'll give the Arctic Silver a try before smashing the XP90 junk...
