X220 Overheating Randomly

Hi,


My  X220 has started pumping out a huge amount of heat, for no reason that I can find. It was running Chrome (2 tabs) and uTorrent, with about 20% CPU usage, when the fan kicked into high, and started putting out enough heat that resting my hand near the vent was painful.
 

I've tried restarting, blowing out the fan, and shutting down nonessential processes, none of which has had any effect.

Any ideas?

 

Thanks.

Hello,

 

Hard to say, as it could have been so many things; an ad in Adobe Flash in the web browsers, antivirus software scanning torrent for malware, etc.

Re: X220 Overheating Randomly

True, there can be several reasons that your X220 is putting out a lot of heat.  Blowing out the fan, shutting off non essentials is always a good start.  However it may be a little more detailed than just blowing it out.  It may be a matter of, dried / separated thermal paste between the heat sinks and the CPU / GPU. This would require removing the CPU and then applying a new coat of thermal paste.  If your machine is still under warranty I would call the Support Center for assistance in setting up a service call.  If it is not under warranty then we can provide instructions on how to perform this task.

Re: X220 Overheating Randomly

CubisHamster,

 

I note that you titled the thread that the x220 overheats randomly, but you seem to indicate a specific situation when this happened that seemed possibly related to particular process tasks.

 

Could you test and tell us a bit more?  Suggest you install a temp monitoring package and note the CPU temp while just at idle, and then how it behaves surfing the web, or opening an application, etc.  

 

Also, ensure you have the lenovo power manager installed.  Are you running a Windows preload, or a version of Windows you installed?

 

I think mbray1 offered some great points on reducing system temps if you find the system is frequently running hotter than expected.

 

Mark

Re: X220 Overheating Randomly

Thanks for the replies and suggestions. I've disabled Flash in my browsers, which seems to have resolved the problem. (Not a big deal here, since my internet connection is rarely fast enough to make use of it anyway.)

Re: X220 Overheating Randomly

I have had a similar problem with my X220.   On random occasions I can smell that the computer is very hot, and when I check the temperature it is near 98C.  However, the CPU meter says that the load is 40%, which is normally not high enough to create this high a temperature.

 

When this happened, Task Manager showed that one of two programs were running, EVEN THOUGH I WAS NOT USING EITHER. One was Chrome*32 and the other was part of Novabackup.  When I killed those processes temperature immediately dropped to about 50C.  I have uninstalled Chrome and deleted the offending Novabackup file, which I do not need for n normal backup,s, and all is well.  However, I still wonder why these programs were running at all.  Is there something else going on that I have missed?

Re: X220 Overheating Randomly

Hello,

 

Maybe some kind of race condition between the two programs?  I believe the X220 ships with the Google Chrome browser, but it's been years since I have seen the Nova Backup software (I recall it being the old tape backup software available for Windows Vista at the time I was looking for such a package).

I am experiencing something similar and can't really figure out why. I notice the temperature going up to the high 90s when playing games (these are old games from between 1999 and 2000, so the graphical and CPU requirements are well within what the X220 is capable of, CPU load never exceeds 40%). Eventually it reaches 98 or 99 and the program crashes. I have found idling temperature to be about 60, which I think is a little high. This is an i7 X220, if it affects anything.

FYI, if it were a problem with thermal paste the air would not be extremly hot as described when blowing onto his hand. As the heat would not be able to get to the heatsink.

Re: X220 Overheating Randomly

I should have mentioned that my X220 is also an i7.
