Pismo Freezes-Up...Fan Problem???

For the past week my Pismo has been freezing-up after 30-45 minutes of web surfing (its primary use). Suspecting the problem might be an overheating issue, I elevated it a few inches off the table; this didn't solve the problem. Usually the fan switches on after 90+ minutes of web surfing, but I don't regularly use the Pismo that long at one time so I usually don't hear the fan (and I haven't heard the fan working in a while). My Pismo definitely gets hot after 30+ minutes of use, so I'm thinking it is overheating (leading to the freeze-ups) because the fan is broken and needs replacing.
1) Do you think the freeze-ups are heat related?
2) If yes, is the fan not switching on the problem?
3) How hard is it to replace the fan? I can change the usual things (items directly under the keyboard - hd, ram, wireless card, etc.), but from searching on the web it looks like replacing the fan requires, among other things, removing the screen (which I've always heard is hard to take off and put back on) and then taking off the bottom of the Pismo.
Thanks.

nomad,
When it freezes, can you immediately restart, or do you have to wait a period of time before it will start? If it does restart immediately, will it run another 30 minutes?
You mentioned it is freezing after 30 minutes, so if it normally takes 90 minutes before the fan runs, you really don't know that the fan is dead. These fans seldom run, so it is unlikely (but not impossible) the fan is still quite healthy.
There are many reasons for your Pismo to freeze, so it is worth looking at them.
1. Marginal RAM: You may have memory that has developed an intolerance to heat. If you have two modules, each at least 128MB in size, you can test each individually.
2. Poorly seated microprocessor card: The Pismo has a microprocessor card that is difficult to seat. If it has been removed for memory or HD changes and not properly seated, it can slowly work loose over time and cause the freezes you are experiencing.
3. Poor thermal transfer between the heat sink and the top of the CPU: If the heat sink has been removed, the thermal transfer pad between the two items should be replaced since it usually tears resulting in poor heat transfer. The CPU may heat enough, locally, to cause a freeze before the fan starts.
4. Circuit boards: You may have developed a hairline crack in one of the boards which opens when heated.
I would try these possible fixes:
- If you have the Apple Hardware Test CD that came with new Pismos, give it a run in the extended mode. See if it can generate the freeze and produce an error message.
http://docs.info.apple.com/article.html?artnum=112433
- Reseat the microprocessor card; use Apple's instructions for installing RAM in the lower slot...it will describe reseating the microprocessor. When the top memory module is removed, press down VERY hard where indicated by the instructions.
http://docs.info.apple.com/article.html?artnum=50028
- Do you still have OS9 installed? If so, download Newer Gauge PRO and run the extended memory test.

Power Mac G5 PPC Screen Freeze Turbo Fan Issue

Hello...
I've read most, if not all of the related posts; however, I have not seen any definitive answer to this issue.
My, almost mint condition, Power Mac G5 PPC has recently started the screen freeze, turbo fan, won't boot issue that seems to be prevalent with these models. I've tried almost all of the suggested troubleshooting fixes and have had no luck. My most recent attempt was to try and start in single-user mode (holding SHIFT + S at startup) and I received the following error screen then turbo fans: http://www.thishateofmine.com/Assets/photos/appleCPUpower.jpg
Remember...this is a PPC, so why am I getting an error referencing Intel CPU Power Management? This leads me to believe the OSX 10.5.8 I've been running has installed system resources for non-existent CPU's and is causing a conflict. This would be a major coding error on Apple's behalf, would it not?
I never had this issue when running any previous OS version and this computer had been running spectacularly.
It has only been used in my clean, smoke-free, home recording studio and if it werent' for a few blemishes left by external HDD's, this computer could pass as brand new. There is very little internal dust and I have kept it clean with electronics approved compressed air. I have not removed anything to get at the PSU area for cleaning, though.
If I could get it to boot from the original DVD's and install up from Panther, I would. Based on the error message I'm receiving, I do not believe this is a logic board, RAM, CPU, etc... issue. The computer will boot into open firmware and function fine, but not the OS; therefore, this would be an OS problem, right? Is that not a logical mental path?
This HAS to be a known issue and have a resolve that is NOT logic board and/or CPU replacement related.
Any help would be greatly appreciated.
BTW...please read this as a positive communication from a frustrated (knowledgeable enough to be dangerous) user. I just want my G5 back.

After plugging in the G5 PPC, as it had been unplugged for several days, here are last night’s efforts:
With only the original, main Hitachi Deckstar 400GB HDD in slot 1, I attempted to boot normal, boot holding SHIFT + COMMAND + V, boot holding COMMAND + S and boot to the original install DVD, all with no joy. In my original post I incorrectly stated I was attempting to boot into single-user mode by holding SHIFT + S, which resulted in the screen displaying the OP’s linked image. In attempting to boot into (actual) single-user mode and verbose mode, I get two different text messages – and have taken screen photos, but have not been able to upload yet – both of which stop with “DART enabled” and then do nothing else with no cursor capability, only to result in turbo fans and having to hold the power button down to shut down.
Next I ran (again) the Apple Hardware Test from the original install DVD and everything passed.
Feeling confident the hardware is all in working order, I used my brother’s Macbook Pro 3.1 (OS v10.6.8) as the host to mount the G5 PPC in target disk mode. The PPC’s HDD mounts up with no issues and everything is accessible, so I shut down and swapped the original HDD with a 500GB Western Digital Caviar SE16 that did not have an OS on it, restarted to AHT DVD and ran test again with everything passing.
Now I reconnected the target disk mode setup, formatted the PPC’s WD HDD and installed Leopard on it while in TDM from the MBP3.1. Everything installed, restarted will still TDM connected, MBP3.1 started up with the PPC’s HDD as the startup disk, went through all the typical initial install information and registration and voila I’m back in target disk mode with the PPC’s HDD as my boot disk and MBP3.1’s HDD on the desktop. Everything’s accessible, functions and looks good.
Keeping in mind I’m only dangerously knowledgeable regarding computers, I’m thinking I should be able to shut everything down and now boot the G5 PPC from the internal WD HDD I just installed the OS on, right? Wrong. All I get is the infamous folder with a flashing question mark.
Help!!! (…please???)
BTW…as it has been mentioned in a few posts, but is one thing I have not done yet, I thought it worth mentioning. I have not replaced the internal battery, but the last time I was able to get the computer to boot to the internal HDD and run for a short period of time, after being unplugged for several days, I did have to re-enter time, date, location, etc… info. The actual last time I got it to boot, I did not do this, as it only got as far as loading the desktop before freezing, but the time was correct. Didn’t get a chance to check date and location, as it froze almost instantaneously.

Pismo Freezes with Netgear WG511T + Orangeware driver - Please Help

Hello,
For months I have been using Orangeware wireless driver on my Pismo G3/400 OSX 10.4 in combination with Netgear WG511T card with no problems at all.
Suddenly one day a black square appeared on the grey background when booting my Pismo. I red that is something to do with Kernel Panic but I don’t know much about that.
So it took several rebooting until Pismo appeared to be OK. But then a few times the screen just went black. That eventually stopped but instead Pismo would just freeze.
I then discovered that if I take my Netgear card out my Pismo, it unfreezes and start to work normally. If I then try to insert the card again while the computer is on the card wouldn’t connect with my router but only one LED would flash.
I eventually reinstalled OS but to no avail. I am so puzzled.
I would be ever so grateful if somebody could make a logical sense of all these symptoms.
Many thanks again

Alex,
Sorry to hear of your contuing problems...
The PC card icon in the menu bar is reporting as expected; see the bottom of this page:
http://eshop.macsales.com/item/Buffalo/BUF80211B/
Have you tried a Safe Boot (restart pressing the shift key), then inserting the card?
Have you uninstalled the Orangeware software?
Have you run Software Update to get the latest AirPort software? It is now up to version 4.2. My suggestion is after Software Update has checked what you need, go to the menu bar > Update > Download Only. You can then restart the computer with shift key down (Safe Boot/Safe Mode) and then run the installers.
I have no idea if any of this will work, but give it a try.
If you have access to a FireWire PC card, pop it in and see if the Pismo freezes; this card is natively supported by OSX. If you wish to test the FireWire card, you will need a FireWire HD that has its own power supply since PC cards supply little bus power.

Random Freezing and booting problems

My MBP (4 years old) randomly freezes and the only button works is the power button. It has booting problems as well
Done already
clean install of snow leopard
PRAM reset
Safe Boot (boots again after using safe boot but still freezes after a couple of minutes)
AHT hardware test with no result
Still freezes after 1 to 15 minutes.
Anything else I cab do?

Wow my first time i use this forum and a fast reply.
Unfortunately not at home at the moment so can not give exact answers.
When my mac book freezes the fan still works, keyboard and touch pad do not work anymore. I don't think caps lock light works but not sure.
Have original ram and a retail SL disc.
When I have booting problems I can see the spinning wheel and after that only blue screen. If I power off and start in safe mode and then restart again mbp will boot again for 2,3 or 4 times and then stop booting again but still freezing after a couple of minutes.
The funny thing with the booting is after I see the blue screen I can still connect from my mac mini and browse my MBP from my mac mini.(screen sharing does not work though).
And do not know what smart status is
But thank you for your quick reply.

PowerMac freezing with fans at full speed?

I have an issue that I suspect is due to a overheating video card.
My mac will freeze, the screen will go blank and the fans will start gradually spinning at full speed. I haven't been able to reproduce the issue because it mainly happens while the computer is idle overnight.
I have been able to reproduce it once while watching an video clip. what I noticed is that if I try to restart straight away the spinning circle under the apple logo (the gray screen before the login panel appears) gets distorted like a TV with bad signal and the computer hangs. I have to leave it for a few minutes to be able to boot.
I opened the computer while it was hanging and the fans were getting ready for a lift off and the small fan on the video card is spinning very slowly. not sure if this is how it should.
Any ideas what can be wrong. I tested everything with the Apple Hardware Test CD. I monitor the temp. inside the computer and everything seems normal. The problem is that it will hang while idle during the night. I will try and replace the video card fan with a new one just in case.
Thanks in advance.

Had this problem and what worked for me (at least for a few weeks so far) was I turned of the Screen Saver and the overnight freeze with fan running at full blast have since ceased. However, when researching my logs to find what was going wrong I noticed that "fan failure" was a symptom and recalled that when heavy video/graphics was being shown when using Safari especially my Dual G5 would occasional freeze up slowly becoming unresponsive, so I turned off first Screen Saver and the problem has gone away, so far for now.
As mentioned above I think it is video card and/or fan related. I was going to get a new fan (because of the system log mention) but will wait longer to see if the problem returns.

The "hanging/freezing/not responding" problem that existed in all versions of Firefox 3.6 persists in Firefox 4.0

Starting on April 14, 2011, I tried installing Firefox 4.0, which I downloaded from the Mozilla site. The first couple of times I tried to install it, it corrupted Firefox file places.sqlite. I know this because the install renamed the file to places.sqlite.corrupt. Luckily, I had recent backups. My previous installed versions were 3.5.18, which I had been using up to this time, and 3.6.16. I tried installing 4.0 with 3.6.16 installed, which I installed only for the sake of installing 4.0, and with no previous version installed and got the same bad results. I finally got a "successful" install on April 16, 2011, with no previous version installed.
Early on I discovered that Firefox 4.0 hangs (Firefox not responding) when left to idle for exactly 5 minutes (I timed it several times after immediately starting Firefox), pegging a constant 50% of the CPU when it hangs. I left it in a hanging state for up to half an hour, but nothing changed. This problem existed for all versions of Firefox 3.6, which is why I didn't install version 3.6.16 until I was ready to install version 4.0. I never kept any version of Firefox 3.6 installed for more than a couple of hours because of this problem. I need to be able to let Firefox stay idle for long periods of time -- certainly for more than 4 minutes and 59 seconds -- without having it hang, and I was able to do that with all versions of Firefox prior to version 3.6. It's incomprehensible that Firefox 4.0 has to always hang if it's inactive for more than 4 minutes and 59 seconds, and it's incomprehensible that this problem has been present and persistent since version 3.6 was introduced. To believe that 4 minutes and 59 seconds is sufficient idle time for a browser is absurd. This was never an issue with any version of Firefox prior to version 3.6, this was never an issue with Netscape, and it's not an issue with IE 8.
There are 2 other problems related to the hanging problem. If the browser and the bookmarks library are both open and the browser is closed normally, the bookmarks library remains open. After being left idle for exactly 5 minutes, the bookmarks library hangs, pegging a constant 50% of the CPU. If Firefox 4.0 is restarted before the 5 minute idle limit, it starts successfully. If an attempt is made to restart it after the 5 minute idle limit, it won't start. If the bookmarks library is left open for less than 5 minutes after the browser is closed, it can be closed successfully. In all versions of Firefox prior to version 3.6, the bookmarks library automatically closed when the browser was closed. The other related problem is that Firefox 4.0 occasionally pegs a constant 50% of the CPU without hanging even while it is being used and even if the only thing open is the home page, which in my case is google.com. Firefox can be used while this is happening, but it is worrisome and shouldn't be happening. Normally, Firefox 4.0 uses no CPU when it is left to idle within the 5 minute idle limit.
Firefox 4.0 has not crashed on its own yet, so I've had no crash reports to send to Mozilla, but because I've had to use the "End Now" button on the Microsoft unresponsive program window numerous times to terminate it when it hangs, numerous Microsoft Windows dump reports have been generated, all of which I've sent to Microsoft.
The last fully working version of Firefox I had was 3.5.18. Unfortunately, I don't have the installer for that version and Mozilla doesn't make it available anymore. Also, it looks like version 4.0 altered the places.sqlite file such that I might not be able to go back to version 3.5.18 even if I could. If I could reinstall version 3.5.18 and get it to work with the altered places.sqlite file, I would, but it is outdated and no longer supported by Mozilla, and I only want to use up-to-date and supported software.
The hanging problem is totally intolerable and unacceptable. If I can't get a version of Firefox 4.0 anytime soon that doesn't hang after being idle for just 5 minutes (why 5 minutes???) or for any limited amount of time, I'll have to install and use Google Chrome as a permanent replacement for Firefox. (If I do have to replace Firefox with Google Chrome, how can I get my Mozilla Thunderbird e-mail links to open in Google Chrome when I click on them?) Based on other user feedback regarding this problem dating back to the very first Firefox 3.6 version, Mozilla has had ample time to resolve it. I have found other problems with Firefox 4.0, but I'm not going to bother telling Mozilla about them because if the hanging problem isn't resolved soon, I'll have to stop using Firefox permanently. I can't and won't tolerate the hanging problem. I have been using Firefox exclusively for many years, but my disappointment with it has been growing since version 3.6 was introduced and my patience has run out.
I would appreciate Mozilla letting me know within a week of this posting if they can't or won't fix the Firefox 4.0 hanging problem. If I don't receive a substantive response to this problem within a week, I'm going to have to abandon Firefox permanently and switch to Google Chrome. I'm also going to leave a negative review of Firefox 4.0 on CNET to warn other potential users of the hanging problem.
I am running Windows XP Media Center Edition 32-bit SP3 on a Dell XPS 400 desktop computer. I have an Intel Pentium D CPU 2.80GHz, 3.0GB Dual-Channel DDR2 RAM @ 265MHz, RADEON X300 SE 128MB HyperMemory, and 190GB of free space on my hard drive. I am using COMODO as my firewall and Avira AntiVir as my anti-virus software. I am also using WinPatrol and Secunia PSI. My ISP is AT&T. My download speed averages 2.5 Mbps, and my upload speed averages 0.65 Mbps. All of my software is up to date, thanks to Secunia PSI and CNET TechTracker, and my computer is free from infection.

Another aspect of the Firefox 4.0 "hanging/freezing/not responding" problem has emerged. I have found that on the common occurrence when Firefox 4.0 occasionally pegs a constant 50% of the CPU while idling within the 5 minute idle limit and I close it normally, it disappears from the Task Bar but continues to run and continues to peg a constant 50% of the CPU. I tried restarting Firefox 4.0 and got the following message: "Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system." Before Firefox can be restarted, the existing Firefox process must be killed via the Task Manager or Process Explorer (I use the latter), after which a Microsoft Windows dump report is immediately generated. I always allow the dump to be sent to Microsoft.
The three big questions that have gone unanswered by Mozilla are 1) why did the hanging problem start with the very first release of Firefox 3.6, 2) why was the problem allowed to continue on up to and through Firefox 4.0, and 3) why hasn't Mozilla fixed the problem yet? And what is the significance of the 5 minute idle limit? Do Firefox 3.6 through 4.0 try to launch something when the browser and/or the bookmarks library have been idle for exactly 5 minutes? Maybe it's a problem with the number and/or type of plugins and extensions and/or the number of bookmarks. Maybe Firefox 3.6 through 4.0 work just fine if there are few to no plugins, extensions, and bookmarks, but that doesn't realistically accommodate users. Whatever the cause of the problem, Mozilla should have had a handle on it by now.
If anyone from Mozilla Support is reading this post, please let me know if it is possible to roll back Firefox 4.0 to Firefox 3.5.18. If it is possible, how do I do it, and where can I get the installer for Firefox 3.5.18? If I can reinstall it, I'll use it until Secunia Software Inspector informs me that it is insecure and no longer safe to use. At that point (maybe much sooner), I'll switch to Google Chrome exclusively because I don't want to use outdated software that is insecure and because I don't believe that Mozilla intends to fix the hanging problem and is willing to lose users over it. I certainly don't want to use software like Firefox 4.0 that has such an impactful problem. If I do have to abandon Firefox, how can I click on Mozilla Thunderbird e-mail links and get them to open in Google Chrome?

Mid 2009 macbook pro battery is dead and fan is constantly ramped up (not due to heat). Would installing a new battery fix the fan problem?

Battery icon has an "x" over it and I need to have my laptop plugged in to be on. I've ordered a new battery to install, but I was wondering if it's possible that something else might be causing the fan to be on over drive constantly. I've tried resenting the SMC and the PRAM, but nothing has stopped the fans from running at higher than normal speeds.

If you've updated to Mavericks, you'll either need to use the original install DVD containing the AHT, or download the right one from Apple's servers, then replace the hidden /System/Library/CoreServices.diagnostics folder.
I think that replacing the battery is likely to stop the fan problem anyway.

Satelite l655 - s5094 - werid cooling fan problem

ok here the deal when my laptops is around 40 C the fan runs at 100% and as the temp rises it slows down to bare min and when the temp hits high then 70 C it gose back to 100 %. i got a colling pad but it barly helped. and fan control with speed fan out of the question unitll they support the laptop. if there a way to change the fan setting that would be great to know.

Heatsinks don't need to be changed. They need to be cleaned, which you've done.
It's not clear from your post, if your fan problems persisted after you cleaned it. If they have, sounds like the fan is failing to me.
Try one these. Got the part number from here. From your model's parts list here.
Please let us know how it works out. Good luck.

BIOS 902 cooling fan problem

Today, I powered my laptop and see the error BIOS 902, cooling fan problem. Then the laptop shutdown. However when I tried to power the laptop at third time, It can start up normally and I can use my laptop for more than 8 hours
I found the solution in google that upgrading the BIOS. However the error 902 still there. My laptop always start up normally at third time.
What should I do? Should I bring my laptop to warranty center?
Thanks for your advance!

IMac 27" (mid 2010): Will replacing the HD cause fan problems?

Hi,
I have an iMac 27" (mid 2010). My HD is broken, and I'd like to replace it. I've already installed an SSD, so replacing the HD shouldn't be much of a problem.
However I've read that replacing the HD causes the fan to spin up all the time. Some sites say this started one generation later, but some remain unspecific or say that this problem affects all iMacs. Before I replace my HD, I'd like to know what to expect.
So my question is: in my 2010 iMac, can I replace the HD without causing fan problems (provided I put the temp plug in the right place )?
Best regards,
F

OWC is mistaken. I don't know why they keep saying that. (I'm not even certain the OWC blog linked above related to using the same make drive on the late 2009s was ever correct. I had a long phone conversation with an upper level WD tech some time ago who said that the originals were special ordered by Apple.) Those drives have Apple proprietary firmware which puts the temp sensor output to the jumper block, and you cannot just replace with a drive of the same manufacturer. A non-Apple WD drive will not have that connection at the jumper block.
Two possibilities: Get an external stick-on temp sensor that will work with your model or use SSD Fan Control.
http://exirion.net/ssdfanctrl/
If I'm mistaken and you do get it to work directly with a replacement WD drive I will be pleasantly surprised, since I have a Late 2009 which will need a new drive sooner or later. Please post back with your results.

Return for Fan Problem (aka mooing)?

Has anyone actually returned their Macbook for the fans coming on and off (or "mooing")? If so, did you get a moo-free MB?
The mooing isn't too bad - and I have hope that software could fix it; but if there are Macbooks that don't moo, man, I would like one. However, no point in going thru the process if there is no possibility of getting a moo-free MB.
Thanks.

There definitely ARE some that do not moo. Or if they do, they do it much softer. Last night I had a white one that, every 10 seconds, would moo. It was horrible. Even with my TV on, I could still hear that fan revv up and then revv right back down, then 10 seconds later the process would repeat itself. I certainly couldn't live with that. I'm a student and would surely be kicked out of class with a laptop that sounded like a zoo, lol.
So anyway, I returned it today (demanding an exchange). What got me is when I explained the moo'ing to the girl, she sounded surprised and that she'd never heard of the problem before. THEN she takes it in back for about 5 or so minutes and comes back out and persists my MacBook didn't have a fan problem. I told her the machine had to be running for about 15-20 mins before it would kick in. Well she's gets my exchange and then continues to tell me "they're supposed to do that." She said hers at home did it. She also even commented about the posts on these forums about it at that point, too. I was thinking, okay then why didn't you tell me that when I explained the problem? I have a feeling the manager told her to tell me that.
Well, I got my black one home today and have been using it for about an hour before work (while it charged), and now for almost 2 hours (running down the battery). I've only been using it lightly and my temp hasn't gotten higher than 60C even on AC power. Perhaps this is why it doesn't moo? My white last night was close to 70C (on light use) and the moo wouldn't quit.
Unfortunately, this one does whine (somewhat loud on AC power, but very very soft on battery). However, that is a non-issue because turning on bluetooth shuts it up right away, or using QuietMBP works also. Whine I can deal with, but there is no work around for the moo.
So, my advice, is yes, return these moo'ing MacBooks. Like others have said, the more returns they get back for this fan issue, the faster they will (should lol) correct it. There's no need in my eyes to sell a laptop that behaves such as some of these do. I do not pay well over a thousand dollars to have to sit in a zoo-like atmosphere. And that's exactly what I told the sales woman. A lot of times I sit in quiet and this fan noise is too loud to ignore. However, I really do believe this is tied to a heat issue, because it is clear some of these run much cooler on light use than others do. That must be why I haven't heard the fan on this one - my temp is much lower than the one I had that moo'ed.

[Other 865 Series] mainboard fan problem

thanks, I'll try it
Quote from: otrofox on 01-June-05, 05:31:44
Have a look to this thread and give it a try.
Take care with temps. After unplugging the sys fan, check your temps immediately and for a long time. Make some tests to ensure this fan is not needed in your Mega.
Another solution should be adding a resistor (from 20 to 80 Ohms) to low the revs.

Notebook fan problem

Hi,
I've had my laptop for 2 years now, my laptop: Compaq Presario CQ60 Notebook PC, has a fan problem. My fan stopped working when I turn on my laptop. After using my laptop for a while (when it starts to turn overheat), my fan kicks in and only works for exactly one hour, after the hour, my fan turns off. While the fan is on, it cools down my laptop. My fan won't working again until a couple hours later or when I restart my laptop and wait for it to overheat again.
Can anyone help me with this problem?

If you just bought it and it's only a few months old then it should be covered for a replacement. You shouldn't be forced to buy a new one, HP should give you one to make it right.
I hear you, if you are busy you don't have time but don't let them swindle you. At least give the computer to someone who does have time and tell them to do a web chat the warranty people and explain that it runs at 98 C (or over 200 F) and that it needs to be replaced and could have burned you. Do this before the warranty period is gone. I think new computers come with a year warranty.
I say webchat because it is easier to keep a record of who you have spoken with and what they say in case they try to weasel out of replacing it. If they give you any trouble about it, post the log or send it to me in a message and I will tell you how to deal with them.
For several months I had to send emails back and forth and go through three years of receipts to get them to honor a warranty and I saved the logs of our chats and I know every sneaky trick they use to try and deny people service.

T5220 Fan problem

Hi,
sorry if this is the wrong forum.
We have a T5220 in the office, yesterday this message appeared
"Jan 30 12:34:06 T5220 SC Alert: [ID 118048 daemon.alert] IPMI | critical: ID = fc14 : 01/30/2009 : 12:33:06 : Fan : /FB0/FM0/F0/TACH : Lower Non-recoverable going low : reading 1600 < threshold 2400 RPM"
Could anyone shed a bit more light on this? It's obviously a fan problem but will it need to be replaced?
Thanks,
Paul

I would have the fan replaced. The fact that it is spinning way under speed is an issue as these very compact boxes require forced airflow.

Pismo Freezes-Up...Fan Problem???
