CPU temp issues on E450

Hi Forks,
I have E450(2xCPU 400MHz, OBP 3.14) running well for many years, but a few days ago, the system has issues WANRING "CPU fans set to MAX, CPU temp is 79" and then it's shutdowned unexpectedly when CPU temp (Warning under OS) reached to 80C.However, room temp is around 20C and fans inside are fine (spining properly).Also, there is another err message "CPU1 is overheating" issued one time before the system shutdowned.
I also tried to do some test steps as physically as pull sidepanel out and see fans spining properly, touch the surface of CPU module and feel that it's very HOT (over 70C) , i supposed that CPU itself is too hot so that it was causing the system shutdowned.
Any one experienced on this issues, pls show me how to resolve issues.
Thanks.

Ok, attach a serial cable to port A and just set the server up using obp as follows:
Pick a maintenance window to take the server off line.
login to the server as root and shut it down

Hi, thanks for your reply, but I still have a few question:
-Why is it necessary to attach a serial cavble to port A?
-set the server up using obp : what is obp ?
how can you while the sequence boot is stopped and you fall on the prompt "ok? <table border="0" align="center" width="90%" cellpadding="3" cellspacing="1"><tr><td class="SmallText">m-lennon</td></tr><tr><td class="quote"> # shutdown -y -i0 -g0 ok setenv auto-boot? false ok reset-all ok setenv diag-device disk ok setenv diag-level max ok setenv diag-switch? true ok power-off At this point power the server on by the switch and allow the system to run through extended POST >=3 times. You can also set this by using the key, but I prefer using the command line. </td></tr></table> I'm not sure to understand your last explain: Running 3 times the server through extended POST: you do this action by putting the switch key on the front panel on diag-mode and start and stop the system 3 times? Otherwise the command line to set this action is "setenv diag-switch? true " right?

2011 MBP 13-inch 2.3 GHz CPU Temp Issue

Hi everyone!
I am new both to the Apple forum and the Mac. Two days ago, I purchased my very first Mac--MBP 13-inch 2.3 GHz (not customized or anything). I've been playing around with the different applications and researching on different forums about CPU temp. In a quiet room, I can hear the low buzz/hum of the computer. I thought MBPs were pretty much silent? Sorry if this is a silly question, but I just want to make sure there's nothing wrong.
On average, CPU temp is around 49-55 degrees Celsius with the fan running just under 2000 RPM which is fine. When I tried recording my voice through the built-in mic on GarageBand, after about 10 minutes, I heard the fan go on full blast. I checked iStat Nano, and the CPU temp was 91 degrees Celsius with the fans running from 6200 - 7000 RPM. Is this normal? I had Firefox, TweetDeck, and iChat running in the background. Should I only have GarageBand open and nothing else in order for the CPU temp to not become as hot? 91 degrees Celsius is around 195 F so that scared me, and my computer was super hot combined with a really loud fan. Should I call Apple for support?
Thank you so much for your help, everyone!

I love Firefox, its the absolute greatest browser in the world I use it myself.
However Firefox and Chrome both are HUGE memory hogs, so you have to be a bit more conservative using them with other applicaiton's open. Occassionally in Firefox you may have to close all open windows and create a new one just to flush the RAM. Because everytime you open a new tab, it asks OS X for more memory and then doesn't give it back.
Also you must remember you bought a integrated graphics computer, meaning the CPU (processor) also does the graphics. This is double duty work the CPU must do and therefore twice the heat in one location.
There is a huge thread on these forums about the overheating 13" MacBook Pro's, perhaps if your a power user or a heavy multi-tasker that your should consider returning that machine complaining about the heat and get a 2.2 Ghz 15" MacBook Pro (or better) with the 1GB Radeon 6750M. It's a MUCH cooler machine and more powerful. I also advise the anti-glare high res screen so there are no reflections in the clasroom or at work etc.
I think you have a 14 day return window.

How do I deal with CPU Temp Issues?

my newly built pc just wanted to shut down b/c the temp hit 80C. I opened it up and the heatsink, cpu, fan everything is not very hot. One spot (don't know technical terms for each piece yet) is a bit warm, but mostly it is cool.
I know this is an ongoing isue with the BIOS. Is this the only way to fix? Does the most recent really fix this? This is my first built pc and it took me a few days to get everything working. I don't want to mess with the BIOS Flash already as I have never done one. Do I just ignore it as long as everything feels cool or should I update the BIOS? Just want to get a feel for what others are experiencing.
The thermaltake fan is set to auto. Perhaps I should just set it too always be on high, which sounds like a little rocket ship and drowns out the TV in my bedroom.
One last REAL STUPID question. Since the temp readings aren't accurate, what exactly is too hot to the touch? Are we talking boiling water hot, where I pull my hand back? Right now the heatsink is warm, but not so hot that I can't keep my fingers holding it.

the case is the Raidmax 668Scorpio. There is one fan at the top, two in front, two in back and one on the plastic door. I think the front back can blow air in or out.
The heatsink is the Thermaltake Venus 12. I set it to blow automatically. It was spinning about 4200rpm when the temp hit 80C. I did apply compound just on the cpu so it does not cover the heatsink fully, but only on the piece that touches the cpu.
I just turned on the pc after shutting down a few hours ago. I went right into BIOS and the CPU starts at 66C. It is cold to the touch, xso no way its 154F.
This doesn't leave me much room to go to 80C and it's not even loaded up windows yet. While I'm typing this on my Dell, I see it has just hity 69C, while just sitting on the BIOS screen.

Possible fix for CPU temp problem found.

Well, one day I decided to take the heatsink off of the nForce3 chip and put some good ol' Arctic Silver thermal compound on there. I figured it might help with overclocking and whatnot. When I took it off, look what I found(!):
Imagine my surprise! Why did they even bother? Ridiculous. After removing their mistake, I put some Arctic Silver on there and re-attached the MSI heatsink (someday I'll probably buy a much better one for it). I've noticed after a couple of days (it takes a little while for the thermal compound to set in) that the CPU temp doesn't appear to fluctuate wildly anymore. Before I was getting crazy jumps from 45C to 65C, but now it hovers around 45C-47C idle and a little over 50C stressed. I've also noticed that my overclocks are a bit more stable now too. For those of you wondering, I'm using BIOS v1.1 at the moment (haven't tried v1.42 yet).
Can anyone confirm these findings? Maybe something else I did fixed my CPU temp issue (I do fiddle with the BIOS quite a bit). My guess is that the nForce3 has a part in determining/reporting the CPU temperature.
I hope this actually is a fix for some of you out there, but don't get your hopes up too high until at least one other person can confirm my theory.

It's very easy to remove the MSI plate. Using a pair of needle-nose pliers pinch the fins on the heat sink on one side together (one at the top, one at the bottom). You don't have to do it too much and be careful. This provides enough slack for the plate to drop out with some slight assistance. Well, that's how I did mine.
I then attached a 40mm fan by screwing into the gaps between the two fins. Only on the one side mind (so 2 screws in total). It holds the fan fine, no rattling.
I have some Artic Silver adhesive and I did consider leaving the MSI plate in place and fixing the fan to it. But I wasn't sure how secure it would be. Plus the plate rattles already, imagine how it would behave with a fan stuck to it.
Unfortunately, I forgot to make a note of the NB temperature before I did it. And I can't for the life of me remember what it was. So I can't say, for sure, how it has effected the temperature. I'm sure it has though.
I suppose it's easy enough to disconnect the fan to find out. I might try that later...
Running at 230x10 (stock = 200x10), MBM reports:
Case = 37C
CPU = 35C
Sensor 3 = 49C
The sensors are labelled by MBM, so I am assuming they respond to the correct items, ie the CPU temp is actually the CPU temp.
This is after a hour or so with Azureus running, mIRC open, a couple of IE windows and SETI running at ~97% CPU
When I take the side off to disconnect the fan again, I will take a picture.

Another Temp Issue - Kooling?

Hi All, I have greatly appreciated what I have read here in the last few weeks lurking. I have learned much but the one thing I cannot seem to solve is my CPU temps issue.
My CPU Temp w/ Bios 1.6 and C & Q, w/ no OC was 49C Idle, and about 57-60C after gaming.
Updated Bios today to 1.7b and C & Q, and it added 4 degrees to that.
My steps to this date in remedying this have been:
- Replace stock CPU Heatsink with Thermaltake SilentBoost K8 (dropped idle 5C down to the above 49C in Bios 1.6) Fan Speed ~2450 RPM
- Reapplied Artic Silver 5 in the manner described on the given website * the BB rice size thing
- All cables inside are nicely tucked away for max airflow (have a Scorpio 868w case) and the case has a total count of 8 fans.
- Installed latest CPU Driver from AMD
My above readings are from Core Center 1.6.6.0. With Speedfan I get 49-50C CPU and 32c System. Bios is a different story, 60C!
Any help would be appreciated. I know these temp issues are a continuous subject and hate to ask for redundant info. I am wondering if I need to purchase a separate Cooler such as Koolance though would not be excited to shell out another $200. I am intent on getting an ATI Radeon x800 Pro but not until I stabilize temps. Thanks all!!!

yep it is cooling. Play on words. Had just been reading up on Koolance Cooling units. I just don't think adding cooling is a solution. My case is quite clean inside with wires bundled, tucked away etc. I have 80mm fans 2 front, 2 rear, 1 side, 1 CPU, and 2 PSU Fans. Quite windy in there. If there was a true airflow issue or overheating in the case, why would System Temp run at 32C? I live next to Seattle, WA so safe to say it is fairly cool here usually including in the house. I brought the case out of its desk enclosure for the best air intake.
After the many threads here and in AMD, It does make more sense that it would be some sort of discrepancy between the CPU Thermal Diode and how the MoBo / Bios interprets the CPU Temp. That's a rehash of what I have been reading and is making more and more sense.
Am trying to be proactive on this temp thing to see is this for real or artifact. Truth be told, this mobo/cpu makes a smokin fast machine and have no complaints, reboots, BSOD, stability issues on Prime95, Memtest etc.
Live Update shows Bios 1.7 today! I flashed with the Beta one yesterday, what timing! Is there reason to reflash with this release?

P6N Sli Platinum front audio panel and CPU temp voltage issues

Hi All,
I got my P6N Sli Platinum yesterday, build up my computer without any major issues. However I have noticed that my audio front panel does not work. It could not detect my microphone when i plug it into front auido panel, it works fine for the rear auido panel though.
Another issues is I highly doubt the accuracy of CPU temp sensor. Msi 's software monitor reports my CPU temp is around 19-20 degree, I know that's too good to be true even I am using a water cooling system. Btw my cpu is E6600. Anyone else has the similar issues?
The third, I notice my CPU voltage is bouncing between 1.1 to 1.24 in CPU-z. And the multiplier is changing from 6 to 9, frequency is changing from 1.6g to 2.4g. I only see this in CPU-z. Msi 's own software reports CPU running at 2.4g though. Is this cpuz issue or something else?
Finally, any tips to max the overclock potential of this board? I have overclocked to 3.1g but there are some crashes. Going higher the board just won't boot up. I read a review on anandtech.com says 1.22 bios is good for oc. Where can i download that? I only found 1.1 bios on official site.
Any reply will be appreciated.
Cheers

C2D-CPUs have a digital internal sensor to monitor CPU Core temperatures. Have a look at those with Core Temp ( http://www.thecoolest.zerobrains.com/CoreTemp/ ). This Tool reads the temperature data directly from the register of your CPU. There is nothing wrong with the sensor. It is rather the MSI tool that does not read the data it provides correctly.

There is no issue. What CPU-Z allows you to see there is the C1E-feature of your CPU at work. When there is nothing to do your processor will automatically reduce Core Voltages and frequency to save power and keep temperatures down. As soon as the work load increases the multiplier is set back to x9 and core voltages increase dynamically. It is meant to be a good thing.
I have overclocked my system a little and I like that the C1E feature is still working at this speed setting CPU frequency to 2GHz and core voltage to 1.144v when my system is idle.
If you have problems with this feature you can turn it off in BIOS. The option is labeled as "C1E Support" and might be hidden somewhere. You may be able to hit "F4" to unhide it.
The MSI utilities are not the best tools to monitor your system. CPU-Z, Core Temp, Everest, Speedfan, Memset, Rightmark Memory Analyzer for example do a far better job.

K9N-Platinum wrong cpu temp + nforce drivers problem

I have a msi k9n-platinum (ms-7250)
Cpu : Amd 64 x2 3800+
4 * 512 ddr II 533 samsung
Asus 7900 GT
6 x maxtor sata hd's
Power : hyper type-r 580 watts
pioneer 110d
lg combo cdrw-dvd
When i builded the system , i installed Windows XP + Sp2 , made all windows updates
After i tryed to install the drivers a got wit the cd.
My system was very instable (i had no problem whit the motherboard i had before)
I made the install more than once , but still got instability
So i went to the nvidia site and downloaded the drivers for the chipset from there , and also made a bios update to v 1.2
System went stable.
Tried again after the bios update with the original cd --> not stable , randomless reboot
so i'm now working with the nvidia drivers from the nvidia site , it's stable but when i go to bios i see that the CPU temp is -38°
Is it a fix for this or do i have a wrong mobo ????

-38°C , seen that a few times now .
I think you should RMA/return the motherboard .
Why , see:

https://forum-en.msi.com/index.php?topic=99573.0
https://forum-en.msi.com/index.php?topic=94762.0
Not the same board as yours but all have a faulty calibraded (non workin) sensor on their motherboards .
The positive thing though is that the boards with this issue that runs on AMI bios doesn't freeze/halt as the award based ones does.

Mac Pro 2.66 (2006) CPU Temps

It's been a while since I took a look at the my temps and what not using Hardware Monitor but the other day I reached behind my Mac Pro... it seemed to me that it was awfully warm... so it peeked my curiosity...
Today I checked and my CPU temps are all around 135F... as I said, it's been a while since I looked but I seem to remember them being sub-100F at idle...
Am I not remembering correctly?
Thoughts?
Thanks!

See if installing SmcFanControl 2.2+ to create profiles and change default fan speed works, changes the fans.
Rather than wait for the system to heat up, switch to a higher rpm profile for that purpose, say 900-1000 rpm is still just barely audible but moves much more air and cooling. 1200-1500 for high.
Once the fans kick in, or cpus are under a work load, it can end up being cooler than it was.
The new 2009s with HT can be forced to use more power, create more heat. For 2006, the big issue is/was the ATI X1900 and clogging with dust and overheating, which needs to be pulled and cleaned every 3 months.

Anything new on temp issues on the 24 IMac's??

Got a question not necessarily an issue and I've researched it quite extensively on the net. Finding ambiguous data concerning this and if possible I'd like the feedback from you folks before calling AppleCare.
After buying my new 24 inch IMac and setting it up, I noticed the aluminum case upper corners and middle upper edge was becoming hot enough to pique my interest. I realized immediately that the aluminum case would be conducting heat more than my older IMac 17 which has the acrylic case.
I was concerned enough to find a temp widget called IStat Pro and download it to physically check the operating temps inside the case as well as the fan speeds.
The temps seem normal and are all in double figures with the CPU average around 50c. The bridges also are in double digits which seem normal enough.
My concern is that the case itself is apparently absorbing a whale of a lot of internal heat and seems to be functioning as a planned heat sink for the unit.
I'm assuming that the engineers at Apple have given the internal temps the thought it deserves and that my worries are ill advised.
I can't explain exactly why this continues to bug me, but as a commercial pilot I'm well aware that heat and avionics are mortal enemies and eventually cause issues in solid state circuits.
I guess what I'm doing here with my post is simply asking if there have been issues reported with the 2.66 IMac 24's and whether there might be a downside to the external case temps as time passes.
Thanks much for any insight into the temp issue. Be aware I've searched the forums and have read what I could find here. Just wondering if anyone has anything new to report.

HI DH,
Check out this thread: http://discussions.apple.com/thread.jspa?threadID=1467276&tstart=0
and here: http://discussions.apple.com/thread.jspa?threadID=1467276&tstart=0
This way you get a better overall idea. If you really think it's running too hot, you have 14 days from purchase to either have it repaired or replaced.
If it were me, I'd talk to an Apple representative about this heat issue. You can Google for this information and it's amazing on how many hits come up.
I just ran iStat on my iMac but it's the 2.66 20"... CPU is 1199 HD 1199 Optical drive 998
But mine never gets hot like you are talking about, warm but not hot.
I'm not running any CPU intensive apps for those numbers. May climb a tad when I have iTunes running....

100% CPU utilization issue by Adobe Form

Hi
I am creating a new Adobe Interactive Form in my web dynpro java application.
When I am trying to run that application on server which is having only 2-3 UI elements in interactive form it's using 100% CPU and adobe form is not getting render.
Some of the adobe forms are already working properly on the server.
Does anybody faced such issue or somebody knows what may cause this issue so please help me out on that.
Thanks
Ravi

Clear CPU Temp folders START->RUN-><Type TEMP> you will get processed Forms that are locally stored in your system Temp folder select all and delete.
and also START->RUN-><Type %TEMP%> and delete the corresponding files in that folder.

MBP 2.33GHz Core 2 Duo, CPU temp constant 90 degrees C at high load

I have a 2.33GHz Core 2 Duo MBP. Not sure which chipset, but not Santa Rosa. I'm still running 10.5.2 because I don't want to stop the process I'm running at the moment.
Anyhow, I'm running both CPUs at full load, and the program I'm running is very SSE-heavy. iStatPro reads the CPU as running at 90 degrees C with the fans running at about 3800RPM. It's been running like this for several days straight because this is the fastest compute hardware I own. I have three PC case fans pointing at the notebook, so the exterior is relatively cool, as are the other temp readings, but the CPU temp makes me nervous. Various things I've read suggest that about 85C isn't so healthy for the processor. Is that true?
I did try calling Apple Care, but they basically blew me off, suggesting I use external cooling. I could take it to the Genius bar, but that'll be a good 3 hours of my time, so I need to make sure it's worth it.
Comments?
Thanks.

See this article regarding runaway applications:
http://docs.info.apple.com/article.html?artnum=304882
and use that technique to make sure that no other heavy applications are crashing the party. There will be a number of smaller system apps and processes running; you're looking for a big hitter that you did not want.
I hear that the MBP is good for 100°C/ 212°F. I'm a little surprised that you're getting only 3800 rpm at 90°. Fans should be able to turn up to 6000 rpm. You may wish to download smcFanControl.
I use that program to increase the resting rpm from 2000 to about 2500 to give a head-start on any heat issues. At 2500, the fans are not noticeable unless I put my ear an inch from the the computer. The program also has a quick-change setting that lets you quickly bump the fan speed to the max of 6000 if things get too hot too fast.

CPU Temp spike to 120c for no apparent reason. Help!

Hi,
I've got a 2.5 dual G5 4gb ram and yesterday I noticed the fans were running constantly for about 5 min. I had Photoshop and Illustrator running so I didn't think much of it (cpus were running at about 60% in activity monitor). Next thing I know I get a black screen that went away after I moved my mouse (It did this twice). I quickly shut down the programs and all was well. I did a bit of research and figured out that this is due to the cpu's overheating and it's putting the system into sleep mode. It's never done this before, and I work on these programs daily.
Well, I decided to download a temperature monitor today so I could keep an eye on what the temps are. I was listening to a podcast a that was approx. 30 min long (no other software running but Firefox, activity monitor, and the ). CPU temps were ok (around 65-80c), but suddenly the fans started screaming and the screen went black. When I got it to come on (only got it to come on for a few secs) I noticed the temps on both cpu's were running at over 120c. I shut down Safari and every program I could think of, but the temp remained high. I was afraid of frying my cpus' so I shut it down via the apple menu. The monitor went black, but the fans continued screaming so I held down the power button.
Now when I try to start it up I get the normal ding, but a black screen. When I look through the mesh on the front I see two red lights (I'm guessing where the cpus are). Please help me determine what the cause of this is! I'm a designer and this is my only source of income. Thanks in advance!!!!

Well, I've taken it in to my local Mac repair shop. I'm wondering if the coolant is coming from my power supply (which is under warranty and was replaced 2 months ago), or if it's a separate component. I know this is a known issue with the liquid cooled G5s, and I hope that whatever is wrong will be fixed!!
When I was carrying it out to my car to transport today the coolant leaked all over my floor. I had both my dogs indoors and I didn't notice the trail of liquid till I got back (almost an hour later). I really hope neither of them licked up any of it! Between this and the potential fire hazard I'm almost starting to question on whether or not I even want it fixed. I'm literally afraid of my computer..lol.
I should be hearing back from the repair shop tomorrow. Fingers crossed this leak didn't fry my cpus and logic board. At temps like that I don't see how it couldn't!
Thanks to all of you for your help!

What's the deal with my cpu temp! I need a HSF!

I have an MS-6734 (KM4M-L) with the stock HSF & 2500+ barton cpu. corecenter (the new version 1.5.8.0) reports (running nothing but IE) my cpu temp at 57C. (not overlocked.) I had to reseat the cpu to make this board POST when I received it, and it had the typical cheap pink thermal pad that once i removed the HSF may have taken most of its effectiveness away? i keep reading how people's cpu temps are in the 30's and it blows me away... my wife has an athlon 1.2ghz on an msi ms-6340 that also lacks any real paste and her temps show idle 53-55C as well. Do I just need some good thermal past (like arctic silver?) to bring them down in the 40's? I have my finger on the buy button on newegg for the paste but am also looking for a good HSF for my 2500+. With this current mobo I am not able to overclock it (no settings in bios and corecenter locks it because i'm using onboard video) but i do play lots of games, where my cpu temp currently gets into the mid 60's.
Anyone with this mobo know if the Thermalright slk800 will fit, i'm also in a small case with the psu about an inch (25mm) from my stock hsf, i've read that some people have issues with fitment with the SLK series contacting caps on the mobo, but their website shows it to be compatible with all motherboards. I'm also considering the Tt volcano 9 since it's cheap and i'm 99% sure it will fit. Any other ideas would be good, i've read the Vantec Aero is good too, but some people had issues with the vibration. I just don't want to order up a fancy new hsf and have it not fit in my cramped case and matx mobo!
thanks for any advice

hi
i am having a problem with a MSI KM4M-L with Athlon Xp 2200+ processor,
the problem is the system shutsdown while working on the pc, this problem is occuring in 2 same configuration pcs now-a-days///
when i tried to check the temperature in the BIOS , i got the problem is in the Temperature part,
as the CPU temp varies from 68 to 70 degrees,
and the CPU Fan speed is 3245 RPM
the HSF is the original one which came with the processor,
what should i do to decrease the temperature ?
what should be the CPU fan speed ?
and any other setting which i should watch ?
please help..

Worried about CPU temp

I've been having graphic issues with my MSI Gf4 and MSI KT4VL, and its come to my attention that my CPU temp is 72. I know thats way too high and could possibly be a cause of my problem. What should i get to cool down my CPU, bearing in mind its an AthlonXP 2100+?

I have the xdream and it works good. It can go as hi as 4800 rpms but yep it makes allot of noise. I flashed my bios to 1.8 and turned on the CPU HALT option and turned down the fan to 3500 rpms. With the xdream and thermal grease(Im not using paste, that way I can spread the grease out more over the heat sink and not worry about shorting out something) I am running my cpu temps at 33 to 37 using everyday tasks and up to 47C under a load such as games. Also I dont have any case fans as of yet, only the case side cover is off. Oh yea, my FSB is Overclocked also.
Hope that gives you a better idea what your system should do with the HSF.

It ALL works (mostly)!!! CPU Temp Monitor??

Just finished assembling my new system and loading it up this weekend, and amazingly, it works. Even with CL3 ram it runs much faster than a P4 1.8A on SiS 645/DDR333 board I had. I am amazed at how big a difference there is in the way XP Pro loads and retrieves data and how smooth it sets up. I did not have to load ANY drivers! A huge step forward from 98SE.
The only issue appears to be that the temperature monitor is out to lunch (So was my last board the SiS645 one, it did the exact same thing) for both CPU and Case. I installed a seperate case system to monitor temp and it gives me 22 deg C after I rearranged the airflow from the fans. I am thinking of drilling out the stock heatsink and inserting one of these temp monitors to real time monitor the CPU.
Has anyone come up with a good way to really monitor CPU temps with this board??

Hey,
I loaded up MBM (after I figured out what it was and where to find it). It seems pretty good: The case reads 37 deg C (my independent sensor reads 27 deg and bios says 47) and CPU reads 47 deg (bios says 57).
The real questions is : My -12 volts reads -6, and I have played with the settings to find the right sensor, and every sensor I select changes all the voltage readings. Is there a specific selection for readings that sets this up right?
Also, I found a Lian-Li temp sensor with thin tape probes that is designed to be set between CPU/Heatsink to provide real time accurate monitoring for chips (theres two, so I plan on doing CPU and NB), so I will have real data instead of hoping it is right. (19.00 US). Nice little 3.5" or 5.25" models avail in black, silver or beige.
