killall-9 Posted October 14, 2009 Posted October 14, 2009 Ok for the past week or so my processors idle temperature has been steadily increasing, it used to idle around 36c, progressively it has got to the point where it now idles around 70c, i checked my thermal paste, i used arctic silver 5, removed and reapplied. this dropped the temp by a single degree for 1 day. after removing my stock cooler i noticed that it seemed to feel lighter, also while the machine is on, with the cpu temp being reported at 70c the heatsink feels slightly colder than room temp(around 70F) is it possible that whatever liquid was in the heatpipes has somehow leaked out? I found no sign of this inside my case around the motherboard, anywhere. however i remember when i initially built the system, the heatsink felt quite warm, as it should. i do not dare stress the system in the event that the cpu is really running that hot, and am currently posting this from my girlfriends laptop. I am going to order the xigmatek rifle cpu cooler on friday, but wondering if perhaps there is another problem, i don't have any other heatsink compatible with the am2+ socket design to test, and am unsure of what else could be the problem. anyone else have a problem like this?

GodlyManDude540 Posted October 14, 2009 Posted October 14, 2009 You could have a bad temp sensor. or maybe the program youre using isnt reading it right or something Quote Share this post Link to post Share on other sites More sharing options...
killall-9 Posted October 14, 2009 Posted October 14, 2009 You could have a bad temp sensor.or maybe the program youre using isnt reading it right or something the sensor i believe is in the cpu die. also the temps are reported the same in linux, the bios, and windows. is there any diagnostic that would test the on die sensor? well other than swapping coolers.

Guest ajmatson Posted October 14, 2009 Posted October 14, 2009 How is the airflow in and around the case? Do you have a hot graphics card? Are you sure the fan is spinning and if it is did you try to set it to manually run at 100% in the BIOS? Is there dust built up in the case? The stock coolers are crap and barely keep a Phenom II 964 (140w version) within operating limits so I am sure the 940 is close to the same.

Actually my stock cooler allowed a 3.5GHz OC for me and never went over 58C in stress testing I know that cuts it close but that's pretty good for a stock cooler. 70C sounds a little far fetched for idle temps. I would say you have a bad sensor or your fan is not spinning. Quote Share this post Link to post Share on other sites More sharing options...
_TheAlexO Posted October 14, 2009 Posted October 14, 2009 If your CPU was idling at above 62 degrees, then it would most likely shut off. im guessing you have a bad sensor. theres just no way its idling at that. unless the CPU is just fried completely. Did you try a heavy overclock or anything? Quote Share this post Link to post Share on other sites More sharing options...

Did you try a heavy overclock or anything? just installed coretemp in windows, it shows my cpu idling at 39c, i did have the cpu oc'd to 3.6ghz, but changed back to stock in june due to the temps rising in my house from summer. should i trust coretemp's reading?

XxHellxRaizerxX Posted October 15, 2009 Posted October 15, 2009 (edited) just installed coretemp in windows, it shows my cpu idling at 39c, i did have the cpu oc'd to 3.6ghz, but changed back to stock in june due to the temps rising in my house from summer. should i trust coretemp's reading? 3.6GHz? On the stock? Mine needed too much voltage for that on stock and the temps were crazy... that there might be your issue.. I would seriously consider buying an aftermarket cooler if you want to OC. A good one for not so much money is the XIGMATEK S1283 or SunBeam Core Contact Freezer. Also just an FYI... your CPU temp (not core temps) should NEVER go above 62C Edited October 15, 2009 by XxHellxRaizerxX Quote Share this post Link to post Share on other sites More sharing options...
Boinker Posted October 15, 2009 Posted October 15, 2009 like Hellraizer just mentioned the thing about that temp.. (70 c) Im pretty sure that chip is a sister to the phenom 940 and after 62c you begin to damage the chip and around 70c is thermal metdown..... so I cannot belive that its still running at that idle temperature. Try it in another board if you have one. may be a bios software issue, try rewriting the bios and see if that helps. if not then its probley the cpu... RMA.

RMA. ok speedfan and coretemp both see the idle cpu temp at 39c, all other monitoring software says 70c, the spec on the phenom chips states thermal shutdown at 62c, at 70c i would have let the magical blue smoke out. So it must be ok, however under full load with prime 95; coretemp and speedfan show the max cpu temp of 56c, so i think i will replace the heatsink with that xigmatek rifle unit anyway, and i'll just get a hardware thermal sensor, and mount it next to the cpu's heat spreader. i checked with asus, flashed the newest bios and same issue with false temperature reporting. i just hope the bios doesn't have a thermal shutdown on the cpu as i have found no way to modify the thermal parameters of the cpu in the bios. the board is a M3N72-D.

OCFreak Posted October 15, 2009 Posted October 15, 2009 I had the same issue with mine as well. I knew it was running cool because I could touch the heatsink. Idle was 32C and load was 46C on stock voltages and clocks. I updated the BIOS for my motherboard, pulled the chip, cleaned and re-greased it with AS5, reseated it and I never had an issue after that.
