109°C (228°F) CPU temperature, fans idle @ 2k rpm!!!!!! I'M SO MAD

this is a issue since the new MBPs were released. as soon as the CPU temp reaches ~55°C the fans start slowly from 2000 to 6200rpm if the CPU is on maximum usage. this is absolutely ok. BUT, if you put your MBP to sleep, log out or change the GPU, something happens to the fan control! the next time you maxing out your CPU power, the CPU heats up to 109°C and the fans keep running at 2000rpm if you reset your smc everything is fine until you put your MBP to sleep (...) again. seriously, what is this apple? this is so so unbelievably pathetic!
the newest "placebo smc update" didn't change anything! it changed not even one thing what it promised, LOL! stop messing around apple and do* something!
temperature issue
15% more cpu usage if you play music over the integrated speakers
display flickering with battery power, between 1-4 brightness

Did you try to reset the SMC, I had a similar issue where my brand new MBP's temps were increasing but the fan speed didn't move beyond 2k. Once I reset the SMC all was well. Additionall download SMCFanControl This handy little app will let you manually adjust the fan speeds. Depending on what I'm working on, I'll default the speeds to 2.5k or 3k (or faster if I'm working on an intensive task)
hm read my post again please.
never mind... ok this is important for me, so i will try to explain this again:
1. on the first boot ever, everything is fine. the temps won't outreach the 80°C mark because the fans speed up properly.
2. after a log out, sleep, GPU change and maybe (i didn't tested it) a restart/shutdown the fan control is FAULTY.
3. the fans speed up VERY slow! the CPU reaches almost _110°C /230°F_! it keeps this temperature for ~2-3 minutes! then the fans slowly kick in and regulate the temperature between 85-91°C @ 4800rpm.
4. so, if i reset the SMC i'll start again at 1. -> the fans work properly! BUT if i close my mac and open it again, maybe just 1min later, the fan control is faulty again... (2.)
btw: i get this crazy temperatures only with programms that stress the CPU, i don't want to know what happens if i activate the 9600m GT an stress it synchrounus with the CPU... (spoiler: nuclear meltdown)
and no, i won't install a app which regulates my temperatures. i don't want to swallow all this pathetic bugs that apple dishes me... i want finally a solution!
so i think, this is more understandable, at least it's written in a better english then in my first post...
lastly, here's a screenshot:

Cpu temperature without fancontrol

Hi, after i installed mavericks, awesome! i clean up my mac and i removed fancontrol.
now, whit fancontrol, the cpu temperature in idle is 40-45 c°, fan rpm abot 3000-3500 and when i open a game, the temperature reach about 80 or more but immediately the fan rpm change to 5500-6000 and it's ok.
whitout fan control, the cpu temperature in idle is 50 c°, fan control always 2000 rpm and the same try with a game, the fan rpm change to 6000 very slowly after the cpu temperature reach 90-95 c°...
i had that problem since i bought this air then i ever kept fan control!
of course now the battery reach 4 and half hours or 5 than before with fancontrol (2 and half hours), but are you sure it's not dangerous?!

You call it a problem. I don't see a problem.
Not only are you are not exceeding the safe operating temp, but it is entirely expected to hover in that area for many types of games.
While not a "gaming rig", the Air is quite competent for many gaming purposes. Just don't expect it to leisurely lope like a Macbook Pro. The CPU will indeed be pushed rather hard in these circumstances. Sure, you may be able to push the fan harder, and acheive a slightly lower operating temp, but I don't see the point.
The fan itself, being a moving part that you can't do much to maintain, is something I'd rather preserve UNLESS the temps were so high, and my need so strong, that I just had to push things beyond the stock cooling system's effectiveness.
Your worries, pertaiing to your post here, are rather unfounded.

X2100 monitoring hardware parameters CPU temperature

Hello all!
I have an X2100 under Linux SLES 10.0
I'm searching Internet for a long time, but cant get an answer.
Is there a way to get hardware parameters (CPU temperature/fan speed etc) via SNMP ?
What software should be installed (of course snmpd is running yet) to do it?
What MIBs is needed?
best regards,
Alex

Hi,
this hardware monitoring tools are not giving the real temp out. I tried Hardware doctor and it says that my Qosmio is running about 120 (!!) so I dont think its supposed to be the
real temperature of my CPU!
If your FAN is running constantly, maybe your fan and cooling system is clobbed with dust. Maybe cleaning the whole thing would be useful. On the other side, try to adjust the setting in the "toshiba power saver" and try to find settings which fit for you (performance/silence) because you have a powerful system and then its normal that your fan is running high.
He had to cool a CPU, a VGA and a little bit of heat out of the case.

Tweak the balance between fan speed and CPU temperature / Dell M6400?

Hi all,
I have a Dell Precision M6400 17" laptop. It runs really well on Arch, but is a bit noisy. It has always been noisy, btw, but I recently noticed that the CPU fan was blowing a lot of air even though the CPU temperature is lower than 70°C. I also have a macbook air, and its CPU runs at 70°C all the time, which seems to be normal. I would like my m6400 to behave similarly, and I'm sure someone here know how to change that

When I start the laptop, its CPU fan stays at its minimal speed only for 1 or 2 minutes, then increases its rotation speed to a second level. It reaches it maximal speed only under heavy load, when the CPU reaches >80-95°C. I would rather let the CPU run a bit hotter before the fan starts to blow: let's say the fan could enter its intermediary speed between 70°C and 85°C instead of 55-80°C, and blow at is its maximum speed beyond that.
I checked the Fan Speed Control wiki page, but lm-sensors is not able to show me the status of the fans. Any idea ?
Aurel.
PS: the temperature of the GPU is not reported by sensors, and nvidia-settings reports around 60°C. Its dedicated fan is very quiet.

Hi aurelieng,
I'm in the same situation from at least 1 month ( INTEL CORE 2 EXTREME X9100, 3.06GHz with 8GB ram, one solid state disk 128 GB, and one sata disk 500GB)
My dell M6400 has dual boot: ubuntu and windows7. The fan works a lot and continuosly in both environment and this is the reason because I have doubt that the origin of the problem is in hardware problem?

Z68A-G43 - Bios shows cpu temperature incorrectly - noisy fan - SOLVED

Hi
I have i7-2600 + Arctic Cooling Freezer Pro rev.2 and when I use Z68A-G43 (G3), the cpu temperature shown in the bios is around 20 degrees higher ( 52-53 degrees C ) , than while I am using the same components on MSI H67MA-E35 or Asus P8H61M-LE/USB3 (30 -32 degrees in both cases ) !
I use the same thermal paste and the cpu & heat sink are definitely seated properly.
The on-board sensors are fine as when Windows is loaded, programs like HWINFO, PCWizard show the right, much lower temperature .
It wouldn't bother me that much since I know that nothing is getting overheated (the heat sink is cold ) ,however, the higher bios indications make the cpu fan spinning much faster ( 2000 rpms + ), I cannot slow it down thus I get a lot of noise coming out from it .
I updated bios to the newest 2.3 ( btw brilliant tool by Svet ) but there was no improvement, I still get the high temps and no option to control the fan.

Just checked again, Smart Fan works at the bios level too, so just the temperature shown is wrong (50-52) instead of ~ 30. I am happy customer now. Thanks again for your help.
This is pretty normal behaviour, my bios temp is ~40°C - 42°C, whilst in Windows the idle temp is ~25°C (depending all on ambient temps).
There are 2 reasons given, which one is correct or if they are both correct, I dont know, but they told me that in BIOS, the cpu utilization is much higher then in idle Windows desktop and/or it is as Jack already described, that powersaving options are not enabled in BIOS, but doing such a good thing in Windows, that the cpu drops its temps significantly.
The reason for the higher BIOS temp then others, can be in the cpu itself, some are just plain hotheads, or have flaky temperature sensors, for instance one core of my cpu will always be at 62°C max, while the other three peak at ~71°C, it just will not go over 62°C.

CPU temperature increases considerably as well as fan speed after upgrading to 10.7.4

I'm running an 8,1 MacBook Pro and just upgraded to 10.7.4. While idle, my CPU temperature now stands at around 180 degrees Fahrenheit and my fan runs at 4000+ rpm. Is anyone else having these issues? How should I try to fix?

Start here:
Using Activity Monitor to read System Memory and determine how much RAM is being used
How much green? under 1/6 pie?
How many pageouts?
When you are comfortable with that information switch to this view:
Runaway applications can shorten battery runtime
What is the biggest CPU User, and how much is it using?

[SOLVED] Question about CPU temperature

Hi everybody,
I just want to ask a question about "standard" CPU temperatures because my laptop (a Dell Vostro 3700) is permanently hot with the fans on even when I am not doing anything special.
I have CPU freq scaling active with the conservative governor, and I use Gnome Shell 3.2 with an nVidia using the nouveau driver.
Here are "stable" temperatures while writing this post:
# sensors
acpitz-virtual-0
Adapter: Virtual device
temp1: +72.5°C (crit = +103.0°C)

Core 2: +73.0°C (high = +95.0°C, crit = +105.0°C)
And this is the output of mpstat

The fan, of course, is full speed (very annoying)
I think that these temperatures are quite high, but I don't know what's really causing all this heating because my laptop is basically idle.
Any suggestion?
Thanks.

Combo: High CPU temperature

Hi,
My PC CPU temperature is 43C when idle. But it rises up to 60C when under load.
The system temperature ranges from 35 to 38 depending on system load.
I have double checked CPU fan, it is perfectly attached.
CPU clock is 3.0 GB 1MB, 512 DDR1 @ 400 MHz
I am running the system on the default clocks (No overclocking).
3 Fans for system cooling.
Is this normal temperature?
Thanks,

Very normal, Almost to cold for a Prescott! I would like to see these temps at my system.....

K8n Neo3 cpu temperature problem

Hi.
I built computer for my friend with these specs:
AMD64 3000+ socket 754
MSI K8N Neo3 nForce4(it's Gold edition, no clue what's so special in it... no msi sticker included, say hello to marketing guys from me )
Asus Pci-e 6600GT 128MB
DDR-400 some brand with Blitz chip, bios settings set to auto
Western Digital 80GB ATA
TEAC DVD-RW
some 350W psu
and the problem is the cpu temperature and kinda noisy fan... newest core center reports 41-42 degrees and 1390rpm when computer is idle, on mine it's around 35 degrees
and 2800rpm. amd drivers are installed, power saving settings are set to minimum cool'n'quiet is enabled, d.o.t. is disabled, but still, core center reports speed as 210x10 = 2100mhz and it should be less when idle... 1000mhz or 800mhz they say... another interesting thing is that core center reports north bridge fan speed as low, while bios health status
reports 7500 (!!!) rpm. what's wrong? please help.

Qool and quiet turn off in bios !

Weird CPU temperature problem

Hi everyone.
The first time I run my system in the morning, I'm having high CPU temp readings by Core Center: 71 C, at around 40% CPU usage, running Norton Antivirus '05, and 67 at iddle. In the same conditions, Motherboard Monitor 5 reads: 67 C for N. Antivirus and 63 C at iddle.
So, I restart computer and check BIOS's PCHealth Status. It reads 46 C for CPU temp.
Then I get back to Windows XP (SP2), Core Center reads CPU temp while running N. Antivirus as 53 C, and MBM reads 50 C at 40%-80% CPU usage. At iddle, Core Center reads 49 C, and MBM5 reads 45 C.
Environment temp is about 30 C.
What do you guys think is happening? Do I need to worry about it or not?
Thanks in advance for your input.
My System:
Windows XP PRO (SP2)
MSI K8N Neo 2 Platinum BIOS 1.30
Athlon64 3800+ no OC
Leadtek A400 6800GT 256 MB
Crucial Ballistix PC4000 2x 512 MB slots 3 and 4
Zalman 7000B AlCu
Vantec Stealth 470A
Raptor 74GB SATA
Barracuda 7200.7 160 GB SATA
SoundBlaster Audigy2 ZS Platinum
NEC 3500 DVD-RW
Samsung SB616 DVD-ROM
SpeedTouch 330 ADSL modem.

I was having the same problem as described by the forum user. Despite my laziness, I even unhooked my CPU fan clean the fan and the CPU and put it back together with Arctic silver. This helped the idle temperature at START up from 50 degree C down to 43 degree C reading from Core Center. However, eventually the CPU temp will creep back up to 47 to 50 degrees C.
My breakthrough came when I read one of the thread which said to uninstalled Core Center, once I done that, my CPU temperature at Cold Start and Warm Start seemed to be consistent at around 36 to 40 degree C (I used SpeedFan 4.18 to verify my temp readings I even crossed check the temp reading with SisSandra 2005 and the two readings are consistent).
I then installed CoreCEnter 1.7.1.0 back and during cold start the temperature will creep back up and keep on increasing. Once I do a warm start everything is back to normal again. So after cold start I open both SpeedFan and CoreCenter side by side and I notice the following:
During cold start, CoreCenter never starts the CPU fan at max RPM, it starts around 2200 RPM or so. Then it would start loading the CPU varying from 1 to 4 to 100% (this happens intermittently so you won't see it if you are not staring at the screen), which would increase the CPU temperature (this is observed in the SpeedFan monitoring screen). Then it would lower the CPU fan back to 1850 RPM or so and does not increase the fan speed even when temperature goes back up. The problem does not seem to exist when one does a warm start then CoreCenter lets the fan stays at maximum speed and the temperature is stable.
I noticed when I downloaded the new CoreCenter version 1.7.1.0 software from the MSI web site, it said "fixing fan speed never reach maximum problem", so I believe this is a CoreCenter software bug. BTW, I just went back to the MSI tech support web site; it no longer showed this message. I have a feeling that they removed the message from potential liability with high temperature issue that might have led to many MB returns. (I know this is sounding awfully like a conspiracy theory)
This is my conclusion:
(1) CPU temp reading from core center is accurate minus about 3 to 4 degree C cross checked again other utilities. (If you system reaches 60 to 70, I should still be alarmed, do not just let the system idle, because it could be an actual reading minus 3 to 4 degrees).
(2) CoreCenter never let the fan reaches maximum speed during cold start and will load the system gradually therefore increase CPU temperature even more.
(3) After warm start, Core Center goes to normal and let the CPU fan goes back to maximum speed.
I know this is not a very scientific observation, nevertheless it is reproducible on my system. Please note that I have a Neo Pla set up not Neo Pla 2 therefore results might be different if you have a Neo Pla2 set up. I really doubt that would be the case since CoreCenter only has one version for both motherboards.
Please give this a try and see what you find, I am curiously to see what other gets. If we can all produce the same issue, perhaps MSI will come out with an updated version of CoreCenter again.

CPU temperature utilities...

I've used three different utilities to check CPU temperatures (Core 2 E6600, the heatsink is Zalman 9700LED):
pcAlert4
Core Temp v0.94
Intel Thermal Analysis Tool (TAT)
The Orthos Stress Prime provided 100% CPU utilization in addition to TAT. All three of the utilities showed different temperatures under the same load; Intel's TAT showed the highest and MSI's pcAlert4 the lowest temperatures. That's fine, although MSI really should get their own stuff right.
I've also noticed during testing that it doesn't make much of a difference, if the Zalman heatsink's fan runs at low, or high RPM; well, other than noise factor. The differences between the low/high RPMs from the temperature's perspective are 2-3 degree Celsius the most for both idle and 100% CPU utilization. That's hardly a reason to run the fan at high speed, especially when the temperature tops out at 55 degree Celsius with 100% CPU utilization for a prolonged time. At idle time the temperature of the CPU is around 32 degree Celsius, depending on which utility is red.
Is this normal for the Core 2 CPU, or neither of the utilities show the actual temperature of the CPU? I'm leaning toward the latter one.
TIA...

Eeh.. warning. When I stopped my CPU fan my computer eventually crashed because Jmicron got screwed by heat and all my IDE HDDs disconnected while in Windows.
It took a moment to get Jmicron to detect HDDs again after shutdown, and once after that drives disconnected again in windows. Now it seems to work ok.
Tho maybe because I didn't bother to close my computer case, and that side panel has 2x120mm fans mounted on it, so there was only PSU's cooler running
Well, thanks for the warning; I did close the side panel, after I disconnected the heatsink's fan
I don't use JMicron; the four SATA drives are connected to Intel's controller. Additionally, the drives are in a separate compartment from the motherboard with it's own 120mm case fan to cool them.
The CPU temperature without the heatsink fan is 34/32 degree Celsius for core 1 and 2, which is just couple of degrees higher than with the fan running. Maxing out both cores to 100% with two instances of Ortho Beta running raises the temperature to 52 and 50 respectively. Playing GRAW without the heatsink fan running results in around 48 degree Celsius, which also just couple of degree more than the heatsink fan is running.
My initial suspicion of the two 120mm case fans around the heatsink are the reason why it doesn't really matter at what speed the heatsink fan is running at was correct. Yes, the case panels were in place and the three 120mm case fans and the power supply's fan were moving the air evidently rather well.

And if you are just curious. You will find some screen captures from my testing in this thread. (bottom of 1st page).

Nice experiment, which probably would've been better if you close the side panel.
My machine is still running just fine without the heatsink fan; the Zalman 9700LED is pretty darn good, it can keep the CPU at normal temperature without its fan. The Antec P180 case helps a lot, it has great airflow and not even noisy.
Well, this was fun; time to turn on the heatsink fan. I just feel better if it is running...

Which CPU heatsink/fan for Z77A-GD65? - if 90 C at 100% load is too high?

With stock Intel heat sink and keeping the CPU (i7 3770) load at 100% for hours, the CPU temp hovers around 89-90 C. My case has 2 x 120 mm fans in the front and 2 x 120 mm fans on the back of the case, . With the room temperature of 20-22 C, the typical idle CPU Temp is 30-32 C.
Two questions please.
1) Is keeping the CPU temperature at 90 C all day "safe"?
2) What after market heat-sink would would recommend for this MB, if the temperature should be dropped few degrees.
My observation for Z77A-GD65: There isn't much real-estate around the CPU for a large coolers and furthermore, my case cannot fit one of those tall cooler heat sinks with 120 mm fan on the fins.
I don't overclock, but run multiple CPU intensive simulations.
i7 3770,
Z77A-D65 MB,
Corsair 750TX PSU,
Corsair Veangeance LP 4 x 8GB RAM ( CML16GX3M2A1600C10)
using internal INTEL graphics and I have 5 x 1TB HDD's of various brand.

UPDATE:
Thank you again for the good suggestions.
I installed Arctic Freezer 13 CO cooler and the temp dropped about 25 C from 90C to 65C with 100% CPU load (my simulation program) for nearly 10 hours.
Tested on Prime95 => 71 C max after 10 hours. Before the upgrade, I dared not run prime95 because the temperature would quickly shoot up above 90C.
IntelBurnTest 2.54 Max Stress => 80 C max
The 92mm cooler fan clears barely above the low profile RAM. It may not fit on high profile RAM( those with high heat spread) Max RPM is about 2100. It's very quiet. I cannot tell apart the cooler fan noise over the case fan noise. After trying to get optimal fan speed using MB BIOS and MSI Control Center, I decided to turn off smart fan control and leave the fan speed at 100%. This "CO: Continuous Operation" fan is supposed to last a long time anyway.

Regardless of temperature fans always at maximum speed

Hey,
I have a 'Refurbished 15.4-inch MacBook Pro 2.6GHz Quad-core Intel i7 with Retina Display'
It was working fine until yesterday (I've had it 11 months) when the fans decided to just stick to max spin rate (5900 odd) i tried the SMC reset. It did nothing. Reformatted the whole Macbook, even while reformatting the fans were going at maximum.. still the same problem. Did a hardware test and it just returned a SATA problem which i googled and most people said you can ignore it.
It was left off all night and when i came to use it the next day it was actually okay (Was at or around 3000) for about 30 minutes now it's just back to maximum again. Even if i have no programs open and the activity monitor shows CPU load has like 99% idle CPU the fans still run at maximum. It's okay for the most part besides the noise until it gets to a point where the whole computer slows to a crawl. Everything is delayed by like 10-15 seconds even if i have no programs open. The only way i've found to fix that is to shut it down for 5m or so, after booting it again fans still stay at maximum speed but it's usable again.
I have a genius appointment Monday but is there anything else i can try between now and then? I've just got a feeling they are gonna make me pay for any problem even though it's still in Warranty because it was dropped 4 months or so ago but the problems only started yesterday. I did actually go to Apple when it was dropped but i couldn't afford the screen replacement but i still feel like the will pin any fault on me causing it as opposed to anything else.
Thanks.

It was looked over and they said the only thing was the screen. Why would a temperature sensor be fine for 4 months after it supposodely broke?

K8N Neo2-FX new CPU temperature problem

Well, I'm not sure if this problem is unique, but I didn't find any help by using search or google.
Problem is this: CPU temperature keeps going up slowly but very persistent and then the computer shuts down about somewhere between 80-82 degrees Celsius (says BIOS). Heatsink is warm when is touch it, i would say the CPU is max 40-50 degrees "hot". CPU is 3500+ Venice. These 2 are brand new parts. BIOS version is 1.B.
Computer was running fine one evening, night and morning (about 10 hours) with Windows XP, and then all started: shutdown. I waited couple minutes, re-started, went to BIOS H/W monitor. Temperature reading was about 50, then it was slowly rising to 80 degrees and shutdown. I instantly restarted and went to BIOS. Temp was about 70 and rising. I shutdown it manually, touched the heatsink and it felt perfectly normal (warm). I'm using the boxed cooler that came with the CPU. Fan speed is about 3150 rpm.
Right now only attached parts are PSU, MB, CPU, AGP card and 512MB DDR so I just can go to BIOS and check the temp. I have tried different PSU, AGP card and memory, the problem stays. It always starts from a reasonable value: 25 degrees after being down for a while and higher if i have tried it on. It takes about 2 minutes to go from 30 to 80 degrees.
Is this a sensor problem, CPU problem or what? One more notice: Motherbard monitor gave strange temps in Windows. Most of the time it was OK (50-55), but then both values were 0, and then back to normal. I noticed the zero values before the 1st crash too so this can be a sensor problem.
Installation failure is not possible, i have worked with computer HW over 10 years. I removed the heatsink, put it back and it fits perfectly. There is no way the CPU is 80 degrees hot. I've touched thousands warm heatsinks.
Should I send the MB/CPU package back or do you have any tricks I can try?
Thanks for reading and sharing my pain

I didn't change the thermal compound when I removed the heatsink. I checked that it is OK, some sort of gray grease, but not anything compared to arctic silver, but not a rubbery "pad" either.
Like I said that original compound is a one shot deal. It needs to be replaced... with the same material according to AMD for warranty purposes.

- I decided to start the computer to Windows, everything seemed to be ok, MBM showed 42 degrees about 1 minute. Then it got to 45-46 and stayed there.
- I downloaded the SpeedFan and installed it. Core temp 45, Vcore 1,40 - 1,41V. Stared the screen couple minutes, stable.
- I decided to try with a load. I Started 3DMark2001 for 5s and shut it. Core temp was 65! Very fast peak Then it went down to 53 and the weird dance began... 53-63-54-64-54-64-53-63... with the same rate than SpeedFan refresh rate. This state was stable now, I stared the screen 5 minutes and the graph showed 10 degree peaks all the time, fully idle CPU.
- Another start with 3DMark, now 30s and i halted it. 80 degrees! Heatsink was as warm as normal heatsink can be in idle computers. And then it went back to 53-63-53-63 dance.
- 15 minutes passed and I decided to boot to see BIOS values.
Weirdest part: BIOS is showing 67 degrees, rising 1 degree/ 2 secs to 80 and shutdown Vcore 1,37 - 1,39.
Conclusion: Windows is more stable than BIOS In BIOS it raises the temp to 80 and crashes, but in Windows I can do surfing and normal work and the temps stays reasonable as long as I put minimal load to CPU.
Like Syar said, CPU "halts" in Windows will result in lower temp.

Now I really think there is some kind of sensor failure. 10 degree dance in idle state is not normal. Fast peaks are normal if the heatsink is not touching the whole CPU (core) surface, but in this case it's fine. Crashing in BIOS is 1st time for me if the computer is idle stable in Windows. I'm sending both back, CPU and MB.
When you get the 10 degree jump, what does SpeedFan show for CPU usage? Also Look in Task manager/Performance to see what the CPU graph looks like and if you run Process Explorer from www.sysinternals.com you will be able to see which process is using CPU. It sounds to me like there is a process which is running at some interval and that just a small amount of CPU usage is boosting temperature excessively. Before giving up on it, I'd recheck heatsink fitting with fresh thermal compound -- a good heatsink paste, like Artic Silver will be sufficient -- to be sure, before giving up on it.

MSI Neo2 users, cpu temperature!!!, please post yours!!!

Hi Guys
for the MSI Neo2 865PE users,i want to know, what is your guys cpu temperature while your computer is idle and stressed/underload.
my rig:
MSI Neo2-S (bios ver.1.0) P4 2.4C @stock speed with stock heatsink fan
ATI Radeon 9500 Pro (not oc'ed)
80 GB WD and 60 GB Seagate HDD
Antec 1080 AMG with 430Watt psu
4 fan running = 2 intake 2 blow out
Sound Blaster Audigy
1x512 MB Ram Kingston
and,
i'm using pcalert4, and it shows:
CPU idle=45 Celcius
CPU when playing games=60 Celcius
System Temperature = 29-32 Celcius
please post yours, please... because, i think it is too hot for p4 to have that kind of temperature.
thank guys!!!

I am wondering how accurate the sensors are on these boards.
I don't think MSI (nor any other manufacturer) has a step to calibrate the temperature sensors, so the answer is - not much
They are just relative temp readings, and probably vary from board to board.
Quote
system temp. Board readings are from 39c to 43c but the air temp coming out the back 120mm fan is 31c to 33c.
Air cooling is achieved by transferring heat from hotter components to the cooler air. This will raise the temperature of the exhaust, but never higher than your hottest component. It actually depends where the sensor is located. If you put a card on the PCI slot above the Winbond chip, you would probably observe higher SYS temperatures.

109°C (228°F) CPU temperature, fans idle @ 2k rpm!!!!!! I'M SO MAD
