CPU heating up 40C in idle and 70 in full load

  Hescara 13:54 07 Mar 2014

Hello PCAdvisor, I have a problem, my cpu is heating up very fast and I can't find what causes the heating. My specs are the following: Motherboard: Nf4am2l CPU: amd athlon 64 x2 5200+ GPU: Msi 5670 512 mb PSU: Floston fl500 500wats(brand new) HDD: Seagate 250gb Ram: 4 gb ddr2 800mhz I tried everything, I am sure the heatsink is placed how it's supposed to be placed(it's a stock amd heatsink). It's dust-free and I don't know what to do. Temperatures while idle: 40-45 each core Temperatures while 50% load: 60-67 each core Temperetures while 100% load: passes 70 and if i stays like that for 1-2 minutes it closes. Even watching a video and installing/downloading something heats up the pc to 65 degrees. THe pc closes itself at 70 degrees and even playing let's say dota2 or skyrim and it closes in 5-10 minutes. I don't have the latest BIOS version, is that the cause of heating up? I even tried putting the pc in the coldest room and it still heats up, the temperature just goes down my 2-3 degrees if I do what i said above. I will apreciate any help at all, and sorry for my english, I'm not a native english speaker.

Did the heatsink come with a heat pad or have you applied heat transfer paste such as artic silver

The heat pad is placed properly and I did place thermal paste 1 month ago and it good enough. I am sure of that because someone who is much better at pcs verified it and he said it was allright and now we are all out of ideas.

Cpu fan running? and in right direction?

case fans running and in right direction?

  Hescara 15:35 07 Mar 2014

Cpu fans are running after 35 degrees, so pretty much anytime with about 3000rpm,they are spinning clockwise. I think this overheating began when i replaced my old single core cpu(yea ancient stuff) with dual core.

  Hescara 15:43 07 Mar 2014

Yes it came with the cpu.

Should i try putting my old cpu in there? If yes will the paste on the heatsink be enough?

It was a little quantity of paste in a pad. It is a big difference sinced i had a single core amd athlon 1.8 and now i have dual core 2.5. Before i couldn't even watch a video on youtube on 1080p without skipping frames.

It was a pad with little paste in it so i don't have any left now, i threw it away a couple of months ago. The paste on the heatsink is very little so i guess i won't try to put that cpu at least until i will find it. The previous cpu was a single core 1.8 and now i have a dual core 2.5 and it makes a great difference. My pc just stopped again and i had just chrome+ avast! antivirus and the only tabs i had on chrome were just this and reddit. I think i'm gonna try the previous cpu and see if the temperatures drop.

I had a similar issue although that was upgrading from a quad core to an octo core CPU.

I used my old cooler in this case which was a liquid one and my CPU was hitting temps of 41+ when idle, watching a movie it would raise to 50 although it never actually shut off.

In the end after checking everything and seeing everything looked fine I ended up getting a new aftermarket cooling kit which works a treat.

Now my CPU is around 37-41 while using the PC and I even tested an overclock. Even then it got nowhere near high temps when I pushed it 500MHZ over.

Try an aftermarket cooler and see if it helps in your case.

Also bit suprised your system is cutting out at only 70 deg C . I would certainly recommend replacing the heatsink and thermal paste . As a stop gap you could try ' lapping ' the heatsink . I did mine and got a 5 deg C temp drop .
