CPU TEMP 30 DEGREES HOTTER AFTER 10.6.3 UPDATE

cpu temps running 25-30 degrees hotter immediately following my update to 10.6.3..norm temps are circa 95-110 degrees.. now operating in 130-140 degrees temps..check istat, and smc controls
my specs:Model Name: iMac
Model Identifier: iMac7,1
Processor Name: Intel Core 2 Duo

ok i found the culprit...using activity monitor.. i discovered that apc powerchute was utilizing 99% cpu.. so i quit the process and my temps immediately decreased to under 100 deg. F. i then proceeded to use their uninstall script and remove the program entirely. all temps are now within normal ranges as i have observed them. not sure why the update was related to this.. or what triggered it.. but all is well..

CPU always at highest speed after 10.4.8 update

Does anyone else have same kind of "problems" than I have after todays OS X update? Before the update CoreduoTemp showed that CPU speed was moving from 1GHz to maximum 2GHz. Usually it was 1.5GHz and only in hevy load it was maximum.
Now when running 10.4.8 CPU speed is almost always highest 2GHz. It goes to 1.5GHz for couple of seconds and raises again to max. I wouldn't mind about this new feature but this has straight affect to batterylife which isn't great.

Well, I found the parent process and kileld it the 3 processes i saw, 2 of which were childs to sh, was simply coreduo temp calling reading logs to post teh frequency. Killed them, installed the old speedit version and older cdt, and still at 2.0 (though loads are down a bit from the newer version )
so, apprently it wasnt those.
Does anyoen remember hwo to get the CPU frequency from console , i can't recall and would liek to check if cdt is somehow the culprit.
this is kind of annoying, however. my battery is already JUST over 5000 at full charge, 5077 right now :/ i have to go to apple and try to get a new battery since it loses full charge weekly now heh
let's get this oen figured out, guys!

Running Hotter after 10.5.3 update?

I have a MBP 2.5ghz and it's been running hotter (the bottom) after I did the update for 10.5.3. I've restarted the machine thinking that the systems may clear the cache or some other process was making it run hotter. But it's consistently running hotter now than it did when 10.5.2. Anyone experiencing this also on their MBP 2.5ghz?

This is what I worked out...
I was using Fan Control before I upgraded so I uninstalled it by following the instructions here: Fan control then I downloaded an re-installed the app from the same address, and now she's purring again - Woo!

Cpu temp 50 degrees celsius at idle.

hi, i think i need some cooling..
the temp of my cpu is over 50 degrees celcius at idle, and i am getting worried.
i have tried some coolermaster jet 4's on my system, but they have to be cranked up full throttle and still only bring it down to 50 deg celcius..
i use a high powered exhaust fan and hdd cooler collermaster cooldrive 3.
at mo i have gone back to pentium's heatsink and fan as it is actually quieter and as good as coolermaster's. but i need to get the temp down about 20 degrees!!
funny thing is at high stress the system only rises about 6 degrees, but i would like the chip to last longer than 12 months, so any ideas about some good coolers??

thought l would update this thread rather than start a new one.
I am getting idle temps of 44-46C. I suspect this is too high.
The reason this is concerning me is my fps in doom3 is only 22-25fps when running the time demo demo1.demo. I have doom3 set to 1024x768 with high quality. And l suspenct the P4 thermal monitoring is kicking in and slowing the CPU down. I have applied the ati doom fix and spent hours tweaking with cvars.
Do you think l should re-apply the thermal grease on cpu and zalman?

MBP runs noticebly hotter after upgrades

I am able to monitor the various temperatures around the MBP using a program called TemperatureMonitor. I recently upgraded from 2 to 4 GB of RAM, as well as upgrading my home router to a N from a G (at roughly the same time). I'm not sure what might have done it, but I have noticed that my CPU temps are quite hotter than usual. Before the 2 upgrades my CPU temps would be in the 50s, 60-70 under load. Now, just running firefox and mail, my CPU temp will hover around 75-80. Does this sound normal to anyone else. I was under the impression that RAM upgrades shouldn't place any additional loads on the CPU, and I can't see why connecting at 144 MBits over 54MBits would change anything either.

Pacman9889,
Its really quite simple. More ram equals slightly MORE power usage. More power means MORE HEAT. This has happened to some degree on every laptop (Apple and Others)I've ever upgraded. I will however agree that in most scenario's, its a bit MORE pronounced on the Mac's. I (personally) attribute that to the way mac laptops are cooled not being as aggressive as on most pc laptops (with actual INTAKE and EXHAUST vents, and higher running fans by default). I personally could care less about the noise, so I use smc fan control on my macs to balance it all out to MY liking/comfort zone. To each their own...
Hope this helps!

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.

Macbook Pro has short battery life and runs hotter after firmware update

I installed the macbook pro EFI firmware update yesterday and now my MBP runs hotter and the fan starts running earlier than it has ever done before. Also, my battery lasts 51 minutes from a full charge whereas, before the update, it lasted 2 hours (using the same programs and display settings).
Has anybody else seen this problem?
Please tell me I'm not alone with seeing this. I am hoping that there is a solution and it's better than 'buy a new battery'. The fact that my box now runs hotter with the fan on more constantly would not be solved by a new battery I think.

Also had the problem of MBP running much hotter after most recent Firmware update.
My fans have been running at 6k RPM constantly, and processor Temps have been running at 70-88°.
Following the advice in this topic, I checked the Activity Monitor, which told me both my account and my son's account (which was running but had no actual applications running) had separate Airport processes going nuts – each at approx 80-95%!
Switching off airport and logging out of my son's account almost immediately started to cool the processors, and the fans began to slow down. Switching Airport back on doesn't seem to heat things up again, but if I start to crunch numbers, it all happens over again...
So who knows why the firmware update is making these processes freak out.... weird.

Hotter after updates

Hi everyone,
Is anyone else having the issue of your Ibook running hotter after downloading the recommended updates?

Yes. After running the CPU at high speeds for a period of time, it will get hot. You do not need to worry about it since the fan will turn on if necessary. There are some tools to help you satisfy any curiosity you might have. Activity Monitor (/Applications/Utilities) has a small CPU meter (hit apple-4 or apple-5) to let you see when your iBook is working hard for extended periods of time. The other one is Temperature Monitor, which you can find through Google. It tells you what your temperature actually is. My processor has maxed out around 165° F during heavy loads and I'm still doing alright.

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.

Different cpu temps after warm boot

After cold boot my CPU temp is:
Load: 46ºC
Idle: 39ºC (cool & quiet enabled)
After warm boot temp drops to:
load: 42ºC
idle: 35ºC (cool & quiet endabled)
I'm using bios 1.5b2.

That however is not correct for everyone. MSI is aware of the problem and will be working on it in a future version of the Bios.

High CPU temps after kernel panic.

Recently I've seen my Mac Pro 8-core CPU temps rise pretty considerably, between 10°-15°C after a bone head move on my part.
After setting up a new Vista x64 virtual machine in VMWare Fusion 2, I was trying to get a Linksys USB to Ethernet adapter (USB200M) to work inside this virtual machine, but with little success. After tracking down a driver online which I thought at the time was a match for the chip on the adapter, I tried to load the driver manually in the virtual machine. This unfortunately resulted in an immediate OS X kernel panic; my first and only on this machine.
Since then, my CPU temps have been on the rise. Not sure if its even possible for a kernel panic to damage hardware, but I’m wondering if any low-level software damage resulting from the kernel panic could be causing the higher temps?
I tried a simple restart which did nothing. I have since run the extended Apple Diagnostics and everything appeared OK. Also, ran a “fsck” check and everything appeared OK there as well.
Any feedback, suggestions or advice?
P.S. This is an Early ’08 2.8GHz 8-core Mac Pro with 10GB third-party RAM. RAM has been thoroughly tested and running in the machine for over a year now without incident.
Thanks

No, ethernet ports work fine.
I use the adapter to connect a VMWare Virtual Machine directly to a VPN Netgear router which runs a remote VoIP service, available on Windows only. To make a long story short, I ran into all kinds of performance issues when connecting the Mac via Ethernet directly to this crappy little Netgear VPN router.
So, the alternative was to use the USB to Ethernet adapter to connect only the VM directly to this router. Definitely not ideal, but worked fine with XP.
It was when I upgraded the VM to Vista x64 and tried to install the driver for the adapter that I got the kernel panic and now higher CPU temps.
Still just curious if I could have damaged any hardware?

Mid-2009 macbook pro high cpu temp ( 100C) after every cold boot

Hi everyone,
Every time I cold-boot my MBP, the CPU temperature sky rockets to 100C within 3 minutes at idle with the fans barely kicking in until that point. The activity monitor shows 97% idle with no major processes running and this issue is reproducible every time I turn on the computer. However, if I immediately reboot the computer (warm boot), the computer runs normally (~70C CPU temp, fans @ 2000 rpm). If I do a SMC reset, the computer boots normally for the next immediate single cold boot but symptoms return thereafter. The only way to prevent the high CPU temperatures is to do a SMC reset before ever cold boot.
I'm wondering if someone else has had these symptoms with their laptop and how they fixed it. The system is still under apple care and the symptoms are reproducible but I'd rather not bring it in as this is my daily-use machine.

[VIA] KM4M-V CPU temp

Built a mini system for my bedroom with a Athlon 2500 Barton this weekend. Everything worked great the board is layed out fine etc. Windows loaded and everything is set up and appears to be working normally. However, I am getting CPU temp readings of 60-64C in the BIOS for the CPU. I have tried out three different heatsinks and ran with the case open but the temps are always around 61C. This same chip ran in a different MB was usually around 35-45C. Is there an issue with the MB and it's temp reading? Do I need to make an adjustment in the BIOS I am missing because 64C seems too high for a board that is running normally. Thanks for any help.

Well, as a follow-up, the replacement HSF came today (artic cooling copper lite). I put in on, which is no easy task (more later) and have it running. It started at 50 degrees C (about a 5 degree decrease from the prior HSF) and has been running at about 56 degrees C running folding@home for about an hour. Still a bit hotter than I prefer; another 10 degrees less and I would be just fine.
I'm not so sure that the HSF isn't the problem. The clip mechanism is just messed up. I looks like it would be nice, what with the screw and all rather than the push down clip and the box says "easy installation.". But, getting it centered in the CPU is really quite difficult. There is considerable "play" in the centering and it is easy to get it off the copper plug. In fact, you cannot know you're on it unless you take it off to check, which of course leaves you with having to hope that you hit it when you reinstall again. Then the screw dowsn't help. The instructions just say to screw until it won't turn any more. I was just waiting to hear the tell-tale *crack*.
While the fan itself looks cool, I don't think I would get this one again. I might just end up getting another if it doesn't cool down after burn in.
Thanks to all for the help,

CPU and GPU slow down after system upgrade

Ok, I can't find anything similar to the question I have...but this forum goes on forever
As my system specs appear below, my machine was running quite comfortably a week ago, with same setup...minus the acrylic case and second 120GB hard drive.
At that stage I had "nomal" benchmarking scores 3dmark03 - 5850, Aquamark3 41.000, PC mark 2002 - cpu7020 mem8438 hdd1050.
Life was good and I loved my system
Then I decided it would be cool to upgrade to an acrylic case (which has better cooling with 3 fans) and a second 120 GB HDD to make a striped raid array.
My first concern was the raid Array. I was carefull to buy the exact same seagate hard drive, size etc. the original was only a month old anyway. The second was to use the intel southbridge chip for SATA RAID or the Promise controller? After researching these forums I decided to go with the Intel as it has more possible bandwidth and doesn't sit on the PCI bus.
I got the new case and wearing those stupid white gloves, proceeded to move the components over and trash my "old" metal case.
The windows NTFS format (full) flew by in 30 seconds and I was really impressed.
Once windows xp and all it's drivers and updates were installed, incl sound and graphics etc. I did a 3Dmark 2001 test before upgrading to Dx9...what a bad mark! 3Dmark2001SE - 9950 (terrible for this system).
I thought it was a DX problem...so I installed Dx9
Then opened that corecenter program (the old one, the one that doesn't crash...)
and my CPU was about 5c hotter than usual, it was running at 40-42c (I have standard intel cooling fan). It went up to 55 at times when running PC mark 2002.
This didn't concern me too much a the system was stable at 32-34c and the northbridge read 60c (but we all know that's not true , more like 35ish.
My PC mark 2002 is now cpu4200 - mem4800 - hdd1800
(at least the HDD improved!) LOL
I ran Aquamark3 next...29,900 (ouch!)
Previously my CPU was 8,700 and GPU was 5300
now the CPU read 4400 and the GPU 4600
I don't really notice the speed loss when working, but games and benchmarks tell a different story.
So, My question: What has happened? Why is my CPU power cut in half? and the graphics card slightly slower? The memory speed stayed the same and the HDD speed improved....not a worthwhile upgrade IMO
What went wrong?
Here are my theories.
1) The CPU and system case is getting too hot
Does the CPU "throttle" when it overheats? this could be the reason.
Also both HDD get really hot and the fan in front blows air over them, this hot air could be going over the CPU or GPU. Maybe get 2 HDD coolers?
should I buy a better CPU cooler like the Thermaltake spark7+ ?
2) The PSU does not have enough watts
I couldn't find traces of voltage lack or spikes...but it could still be a problem
3) The RAID0 array is a strain on the CPU and chipset
I'm not sure about this.
My appologies for the lengthy thread, but I wanted to be sure that anyone trying to figure this out had as much info as possible
Thanks if u can help me figure this out.

Perhaps I should upgrade the overall cooling. Get a Thermaltake copper fan and two HDD coolers.
Well, your temps sound allright, no need to worry them, if they really operate at that level.

The solution to set the FSB to 201Mhz sounds good. But do I set this in the BIOS or with Corecenter in windoze?
Propably meant to adust your FSB at BIOS, at least that is what I would suggest.

I will try to re-install the VGA drivers because something strange DID happen when I first installed them. I started with the hercules driver CD, this installed CAT 3.2 drivers. I then upgraded to CAT 3.7 and before it completed I got an error window (send, dont send).
Remove drivers AND ATI control panel first, and then re-install. Use drivers from ATI site, and rather Catalyst 3.7. I Have had problems with 3.8 Catalysts.

Still wouldn't explain why the CPU seems so crippled. I have managed to get a "normal cpu score of 7000+ in PCmark2002 by shutting down, restarting later and killing every process except explorer.
Do you have any processes that seem to eat more juice thant hey should? Arrange your processes by CPU usage and see if there is something strange.

If this cant be fixed I will reinstall over the weekend. Does anyone know of the RAID0 array on the southbridge causing a system slowdown?
I'm using Intel RAID and it works perfectly, no extra CPU usage is shown and it's pleasantly fast!
And Install latest Intel INF updates and Application Accelerator from Intel site. That's what I'm using, and works fine.

Bios reports 62 deg C cpu temp on XP2600/KT4A-V MB

Motherboard Monitor reports the same temp within a few degrees but the cpu doesn't seem very hot at all. This is happening on two similiar systems: same mb and cpu, 350W Antec power supply, 1 hard drive, 1 cd drive, and a 64mb GForce MX4000 AGP video card, 512mb memory.

1. HSF is installed correctly
2. I'm using a thin layer of Artic Silver.
3. One system has 2 sticks of Kingston 512mb and the other one has one stick of Micron 256mb.
But as I said in my original post, the cpus don't seem hot at all. I have another system with an MSI K7N2 Delta-ILSR mb/XP3000. The CPU temp on the XP3000 is 46 deg C and it is noticeably warmer in that I can feel significantly hotter air coming off the CPU. So I'm wondering if MSI is reporting higher temp readings on the KT4A-V mbs because maybe the sensor is on the dioide and not the socket.
