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.

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.
Quote
- 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.
Quote
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.

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 !

[SOLVED] Notebook temperature problem

Hi everyone,
I use Arch Linux (i686) since 2008 on different machines. But my Acer 8935G Notebook is giving me headaches for some time now.
I bought it one year ago and Arch Linux ran nearly out of the box (ALSA drivers took some time, but that's done). In spring I noticed, that the computer is getting hotter than it did before (Idle: 70° Celsius / 158° Fahrenheit). In Windows Vista, I get idle temperatures around 40° C (104° F). And before spring, I got temps booting Linux around 50° C (122° F), which was absolutley okay and worked for me.
I didn't change system settings or configurations, and I tried some possible solutions, because I thought, maybe it's a kernel problem, but that's just a wild guess.
What I did so far:
- trying alternate kernels (BFS, CK, ZEN)
- tried different cpufreq settings (dynamic cpu scaling is working -> cpufreq-info)
- undervolting via intel-phc (no changes in temperature at all)
- tried powertop
none of that worked.
I have to say, that's not just a Arch Linux-related problem, other distributions give me the same problems (PCLinuxOS 2010, Linux Mint KDE 4.4).
My question so far is - has anybody experienced similar problems and found a solution for it?
Thanks in advance for the help - I'll really appreciate it.

Thanks TigTex,
but I can safely say, the temperature problem is real. It's not just a false sensor, because of the heat, the metal-case of the laptop is generating. It really gets uncomfortable when working on that hot case (hands on the hot machine and typing - after a while you can order your hands "well done" *sigh*). Because of that, I switched to an external keyboard, but that's not really a solution. The weird thing is, that the temperature problem didn't exist at the beginning - and it doesn't exist on Windows. And it's also not a cleaning problem - I clean my machine regularly (because I hate dust, generally ).
I can also say, that the fan is working - and it's working also dynamicaly (gets louder, when the machine gets hotter).
I checked the CPU sensors on Windows with Core Temp regularly (runs automatically in system tray at boot).
The machine ran 20 minutes (after 1h I get around 70° C / 73° C / 73° C):

K8TM-ILSR CPU temperature "not present"

I've received a replacement K8TM-ILSR after problems with RAM.
That's now fixed, but now in the Health Monitoring part of the BIOS, the CPU temperature reading is weird:
- at boot up the temperature starts in the 80 degrees C (that can't be right!)
- then it starts dropping, and after a minute or two reaches 20 degrees C and is still falling
- when it reaches 16 degrees C the reading disappears and is replaced by "not present"
So as the machine warms up, the CPU temperature actually drops. After a few hours of being switched on, returning to the BIOS still reveals CPU temperature "not present". Only if I reboot from cold do I get a reading, but the reading is always decreasing until it changes to "not present".
BIOS v1.4 was supposed to correct a problem with temperature reading - my motherboard has BIOS v1.5... so that can't be the problem, can it?
I'm wondering whether to send the motherboard back for a replacement while I still can.

Ah, one more thing: the temperature sensor is on the motherboard, and not in the CPU, correct? So if there is a problem it's with the motherboard not the CPU?

K9N Platinum - Wrong CPU Temperature in BIOS

Hi, I have a K9N Platinum (7250-020) with the latest 1.3 BIOS and an AMD X2 3800+. The CPU Temperature in the BIOS has a negative sign in front of it, and it seems to always report -48*C. I tried the latest nVidia nTune and it was reporting the CPU temperature to be 208*C, which is absolutely impossible...
Does anyone have the same problem? I searched around and it seems I'm not the only one, but I still cannot understand if it affects only some K9N Platinums or all...
Thanks.

I assume you are talking about checking voltages as reported by the BIOS in the HW Monitor page, not physically checking them with a multimeter, correct?
I'll take a look at the numbers in the BIOS, but last time I checked they were ok.
As for raising the issue with MSI, eventually I will, even if they ask you soooooo many questions (for good reasons, I know...) that it would take me half an hour to fill that form...
I've checked with both and software is a little out from what a multimeter state's. Only check with a multimeter if your happy to do so. http://forums.extremeoverclocking.com/showthread.php?t=137886 offer good advise if using a multimeter .....
The only issue I see is the AUX connector for 3.3v with ATX2.0 spec (Modular cables etc)

My solution (or so I thought) to Power Manager/CPU throttling problems!!!

I have found a solution to all my Power Manager/CPU throttling problems!!! Though there is some good and bad news.
{EDIT: The problem has NOT been fixed, even after latest PowerManager (3.62) and BIOS (1.30) versions. Pretty much ignore anything I say below as the problem is still occurring. You can see my full post here: http://forum.lenovo.com/t5/W-Series-ThinkPad-Laptops/W520-Speedstep-not-working-properly-on-battery-...}
Good news: I have NONE of the throttling issues or inconsistent CPU frequency problems I was having before on AC or battery power. Everything, including TurboBoost on battery works! It is completely fixed! (I have no idea how this factors into Lenovo’s statements that TurboBoost is disabled on battery “by design”. There is at least one other post from someone else that also reported TurboBoost was working for them on battery)
Bad news: I don’t really know which one of the many things I tried actually worked. I am sorry I wasn’t more methodical about recording what I did and checking results, but this was my last ditch effort to get this fixed on my own without sending the system in for repair and frankly, I didn’t think it would work. Now that it has worked, I’m hoping my steps can help others.
For anyone interested, here’s what I did… and before anyone says something like “That has nothing to do with managing power/cpu, why would that help?!… etc., please keep in mind I’m just stating exactly what I did. I am aware some of the steps may not be relevant, but who knows… We all know how weird PC’s are sometimes, even the smallest, oddest thing may resolve a problem.So anyway, here goes.
**IMPORTANT** Not sure how many noticed, but there was a new version of Power Manager released a few weeks ago, 3.62. The PM driver seems to have stayed the same. That alone could very well be the sole fix, I’m not sure. You may just want to completely remove PM and PM driver and install the latest version before trying any of the steps below.
1)Made a complete system image via Windows built-in backup feature
2)Disable any 3rd party fan/CPU control utilities (Throttlestop, etc). Make sure they are also not going to run at startup or from a scheduled task
3)Remove Power Manager Driver, then remove Power Manager software
4)Reboot to Windows
5)Remove all traces of the Power Manager drivers/software directories (think it was something like C:\readyapps and C:\drivers.) **For some odd reason after I did this, my wireless stopped working but it resolved itself by the time I was done with these steps, strange
6)Reboot
7)Access BIOS and reset all settings to default
8)Boot into Windows, downgrade to BIOS 1.25 [UEFI: 1.25 - 8BET44WW / ECP: 1.14 8AHT32WW ] via the Windows flash utility. I wanted to downgrade all the way back to 1.06, but the software would throw up some error for any version prior to 1.25 and wouldn’t proceed
9)Reboot to Windows; make sure system booted w/ out issues
10)Reboot again, access BIOS, reset to defaults again
11)Shut down system
12)Disconnect AC power. Remove main battery. Access and disconnect system backup (a.k.a CMOS) battery under keyboard. Discharge residual power in the system (there are various ways to do this, but you could just leave the battery disconnected for a few minutes). Visually inspect the system for anything funky…my system had a slightly but noticeably loose CPU/GPU heat sink/fan assembly power connector.
13)Reconnect backup battery.
14)Reconnect AC power but leave main battery disconnected.
15)Power on. Should get a message indicating “checksum error, system time reset” or something like that.
16)Reboot to Windows. Verified still okay.
17)Downloaded latest BIOS version, 1.26. This time I burned the bootable BIOS flash CD instead of running it through Windows.
18)Restart and boot from disc, flash BIOS to 1.26. Once complete, restart. Verify BIOS set to defaults.
19)Boot back into Windows.
20)Install latest Power Manager driver (1.62 ), reboot if/as prompted. Install Power Manager (3.62), reboot as prompted.
21)Boot into Windows, verified Power Manager was active and working. Verified TurboBoost was working. Restarted system a few times and played around with Power Manager for a bit to see if the different power plans worked and retained the settings, all the while monitoring the Intel TurboBoost utility and PM’s own “power gauges”. Let system Sleep, changed power sources, resumed, etc. Everything was working great.
22)Shutdown, reconnect main battery. Booted into Windows. Again, fiddled with Power Manager for a bit, switching between power plans and AC/battery power. Still worked great.
23)Success!
That’s it. Again, this is not a guaranteed fix guide. These are just simply the steps that I took on my system that resolved the problems many of us are having. Hopefully it will work for others.

(PM driver) http://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles/83ku14ww.exe
Now, I did chipset first (didnt ask to reboot) then installed the PM driver (did ask to reboot)
I rebooted.... then I went into bios (1.26) and set everything to default... then restarted saving changes...
Since I prefer not using optimus I changed the display settings in bios right after saving the default settings...
Not sure whether or not you really had to go into bios... but everything seems to be working...
My settings in PM is set to Maximum Power in the Advanced tab, 3rd party monitoring tools is TPFanControl and HWInfo64....

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?

MacbookPro 13'' temperature problem

Hi everyone, I have a Macbook Pro 13'' Mid-2012 (A1278) with a Intel Core i7 2.9GHz for a year ago, but the cpu fan is a little noisy and I check temperature with a "Temperature Monitor App" and CPU Temp is 80ºC with only Chrome and Coda 2 opened.
Normally I work on 3D applications like Autodesk Maya and AutoCAD, this apps can overheat the cpu but now i can't work with these apps because the performance is very low, I cleaned up the logic board and temperature don't decrease.
¿How can I decrease CPU Temp? I bought a new CPU Fan and I don't want it damage again...
Thanks for help me and sorry for my english I speak spanish

And the magsafe connector is so hot like 100ºC but charge the battery and works fine but is hot. I have 2 chargers one 65W (original) and another 95W from another macbook and both have the same temperature problem.
100°c on the charger body is unacceptable and would be impossible to touch for more than a second. Mine have never been more than 55°c. There is something terribly wrong here. Look at the contacts between the charger and the MBP. Is there any discoloration? the pins in the charger connection are spring loaded, do they move easily?
Fan Speed is 6140 rpm and CPU temp is 75ºC, I think a change the thermal compound.
The CPU temperature is not bad nor is the fan speed. I have doubts about that replacing the thermal paste will improve thew situation.
Open the MBP and see if there is dust an debris inside. I f so clean it out.
Again, delete Google Chrome and see what happens. It has been known to have compatibility problems with OSX.
Ciao.

CPU temperature is too high in Solaris 10 sun fire v890 machine

Hi,
I just installed Solaris 10 on a sun fire v890 machine. I used the prtdiag -v command to check the system.
However, It appears to me that the CPU temperatures is higher than the temperature range specified in the technical specification. The server is a standalone node that does not connect to the network or process anything.
Is it a problem? Thank you.

Hi Rukbat,
Thanks for your reply.
I have displayed the verbose prtdiag -v on the v890 machine.
However, I couldn't find the hard-coded operational ranges. Could you please advise?
Hi Sun-worshiper,
I executed the command and couldn't find the targeted temperature.

Satellite M100 - I can't analyse the CPU temperature

I'm an owner of Toshiba Satellite M100 series (Core Duo T2300, X1400, etc.). The problem is that I can't analyse the CPU temperature changes in such popular application like Everest or Notebook Hardware Control. Also any other software provided by Toshiba and already installed on my HDD doesn't include some CPU diagnostics including the temperature changes!
The only software which seems to be working is the HWiNFO32 so there is some thermal sensor inside which reads this temperature of Centrino Duo processor, but this software is not very user-friendly :(
There is a request for Toshiba to do something with this... I've upgraded BIOS in my model to a version 1.70 but it didn't change anything I could easily notice (or is there any?) :(

Hi
Like Mike said the BIOS update has nothing to do with the CPU temperature monitoring.
The fact is that Toshiba doesnt support any 3rd party applications.
However, all the temperature programs are not precise and dont get exactly information about the temperature. Only the programs with a physical temperature sensor will give you a exactly temperature.
I dont understand why its so important for you to know the temperature. The Toshiba notebooks support an overheating protection and if the temperature increases to the critical level so the unit shuts down automatically.

Mac Pro 8-core X5365 CPU temperature

I've got an 8-core Mac Pro which is crunching SETI@home 24/7, with Hardware Monitor monitoring the CPU temperatures and other vital stats. After reading the Intel Quad-Core Xeon Proc datasheet, I'm a little edgy about the operating temperature of these X5365 CPUs, currently registering at 65 - 70ºC on load for each temperature diode, and fail-safe temperature set to 73ºC to disable SETI@home via Hardware Monitor. I also have smcFanControl speeding up the fans because my ambient temperature varies thanks to myself being in a tropical region, my ambient temperature can reach 33ºC at times, but down to 28ºC when air-conditioned.
My question is, what is the maximum temperature for these CPUs before they run into the risk of being fried/permanently damaged..?
Inputs from the Mac Pro-DC/grid community are also welcomed here.
Thanks.

my 8-core is running seti 24/7 since may without any problem, although my ambient temps dont rise above 30 degrees centigrade...and that's using the optimised apps which make the processor run hotter
the fans on the machine run 600-2000 rpm all day and all night, i dont expect it to lessen the life of the machine whatsoever. it should be capable of running flat out all its life, that is, after all why we spend so much on these machines in the first place !
if you only use 4 cores perhaps you should buy a 4-core mac ? he heh just joking...
as mentioned earlier, when things get really too hot the OS will shut the system down, and if that doesnt happen then the cpus themselves will shut down...
the heatsinks and fans on these machines are fully capable of coping if your macine is running withing the specified ambient temp range which for the mac pro is 10° to 35° if your seeing ambient over 35 then smc fan control is probably a good idea otherwise it should be fine

MacBook CPU Temperature

For the last several months my MacBook fan start to run as soon as I do anything processor intensive - including running a screensaver. As soon as I do something other than read mail or write in BBedit the fan revs up to 6000+ rpm. Looking at iState menu right now: Handbrake is the highest load, running using about 50% of the CPU. CPU temp is 99C, heatsink A 57C, heatsink B 56C, and the Enclosure base is 27C. The fan, as usual is running over 6000 rpm.
Is this normal? Could it be that thermal paste problem? Internet research has been more confusing than helpful.
Applecare is long expired - This is an early 2008 model.
Thanks
-Max

yep. and i bet, your fan isn't even spinning at its 6200 rpm maxmimum to accomplish this.
ok. as far as i understand it, different mabook series allow for different cpu temperatures and accordingly have a different fan behavior depending on which cpu is installed and which buliding materials are used in the book itself. so we can't directly compare your 2007 model to his 2008 or my 2009 model. but one thing pertains to all machines: if the fan spins at it's absolute maximum speed for a longer time period and temperatures do not drop noticeable, and if the fan never showed this behavior before, there's probably something wrong.
either the ventilation is blocked for some reason or the thermal paste is disintegrating. i would have checked it at the store. also, there is this wide gap between cpu temperature and heatsink temperature. for all i know, it's normally a difference up tof 15-20°, but not arround 40°.

K7N2 Temperature Problems

I'm having some small temperature problems with this board.
Here are the temps
CPU: 45-60 (normal-load)'c
Case: 38-45
Chipset: 42-47
The CPU isn't too bad, although I do see some strage fluctuations, like while writing this, its went upto 57 and then the next reading dropped to 47???
I have a laser digital thermometor which obviously can only scan temps external of the heatsinks, but it is accurate, and it does report similar temps.
My main worry here is the case temperature.
Here is my setup
K7N2 Delta 2
athlon 2.5 @ 2.2Ghz
1GB corsair (512*2)
Nvidia 6800GT 256MB DDR3
DVDRW
DVDROM/CDRW
120GB SATA HDD
500WATT PSU (which is heating up a little and could be a cause of this)
3 case fans
thermaltake volcano 12+
I've tried not clocking but there is little difference, room temps are at 20-25'c.
The heatsinks near the chipset seems to be getting rather hot also.
It doesn't have any stability problems. Its fine with games, no slowdowns. but its just the temps.
Can someone please compare my temps with the same board, just so I can get an idea.
Thanks in advance

I definitally need something black...
Otherwise it'd be a little out of place!
In all honesty I wish I could buy things from newegss. they seem to have a great range and nice system.
In the UK i'm reverted to buying from EBuyer (despite their poor customer services!), there prices are the cheapest although much dearer than the US...
http://www.ebuyer.com/customer/products/index.html?rb=3549119343&action=c2hvd19wcm9kdWN0X292ZXJ2aWV3&product_uid=54146
Its way out of my price range. I have £50ish set aside for it, and I'm looking at these at the moment all from overclockers (seem to have best range, not price) :

Lenovo essential G505s (59-380146) CPU temperature

Hello Friends, Hope ya'll are doing fine. I bought lenovo essential G505s (59-380146) finally.
I am using speccy to monitor my laptop. My CPU temperature when the laptop is started averages around 85-90 degrees and during gaming, it reaches to 125 degree celcius.
I have a feeling this is not normal.
Also, on the box it said the RAM is of 1600MHz but speccy is showing it to be be 800MHz. What can be done in this case?
Kindly help!

hi atheos,
Welcome to Lenovo Community Forums!
I checked you system's info.
Due to Turbo core Tech, your system might be Overclocking automatically up to 3.5, one step further to the normal speed of 2.5
Clock Speed
2.5 GHz with Turbo Core Technology Upto 3.5 GHz
This might be being triggered if you run a high processing Application.
and might the cause of over heating.
125 degrees is too hot for a computer and might cause problems.
Try to limit your CPU state to 99% this will stop the turbo core from being triggered then observe the Temperature. It should not be higher than 90 degress.
Check here how to limit the CPU state
Also note that room temperature may contribute.
About your RAM Speed
Software Tools is likely to report half of the memory speed since you have a doudle data rate, you will have to multipy the reported speed twice to get the actual speed
see details here
