Overheating a lot?

I keep my cpu undervolted by a bit, not a lot only .08V. Lately I have been playing Dragon age origins and I had HWMonitor on just to keep track of laptop temperatures. The acpi thrm reading averages 80 degrees C but it always has a peak of 128 degrees C. I haven't been able to replicate that peak with orthos yet and I was wondering if something was defective or it actually reached those temperatures. All the other temperatures the cpu cores and gpu are acceptable.

I"m using a lenovo t61p, t9300, FX 570m if that helps.

 

128C is very high...mine goes to 80C at most... make sure your vents are clean by using compressed air, undervolt the CPU and use a notebook cooling pad... search for the undervolting guide on the forum and undervolt your CPU... should have no temp problems then...

 

I never see more than 75 C when gaming
over 100 is way to much in my opinion

 

ohh trust me.. i have seen my CPU hit 100C when i didn't undervolt and use a notebook cooling pad when playing brothers in arms hell's highway... now my CPU rarely even touches 80C...

 

Try the following:

- stop stressing the machine in case the 128 reading is accurate (the sensor may be reporting a false reading)
- clean out the inside of the laptop with a can of compressed air and a powerful vacuum cleaner
- stress the machine again, watch the temps closely
- if they climb too high, do a hard shutdown as soon as it hits the 90s.
- Apply new thermal grease and try undervolting further

- At this point, if the problem is still persisting then the thermal diode for the ACPI sensor is likely giving a false reading.

By the way, does it feel like 128C? As in, does your hand hurt like hell when you touch the bottom after 2 hours of Dragon Age?

 

That's only ACPI bad reading... If you really had that temp your NB would shut down I believe. Anyway, the real temps are the ones on your cores. ACPI THRM temp should be similar to cores but in your case it's faulty. Try using different temp monitoring software.

 

acpi thrm is not a sensor reading.

It's just a value that is based off the temps of the devices in the thermal zone.
It is used to trigger thermal events like active (fan) and passive (throttling) cooling.

I would ignore the value, unless you have thermal throttling that you want to stop. I have helped other forum users disable thermal throttling by changing the acpi code in the registry. I can do the same for you if you want.

 

Yeah, the laptop should have shut down longer before it hit 128 C, most C2D's thermal limit is 105 C and the processors throttle when they hit the mid 90's.

Edit: i have the same problem, in HWmonitor the GPU temp is always 10 degrees higher than TPfancontrol reads. I recommend using TPfancontrol so that you have a back up temp monitoring program, you can also control the fan speed with TPfancontrol and edit the .ini file to create custom cooling plans relating to the fan speed. I trust TPfancontrol more than HWmonitor because it was designed specifically for the T43's fan noise problem but works for most ThinkPads.
