AMD Phenom II X2 555 Black Edition CPU Overheating on Windows 7 64-bit

I was using the Windows 7 32-bit from last year, but switched to the 64-bit about 4 months ago. Since then I have noticed my CPU temp. is on rise. It was working fine, but as the start of summer season, It goes to 70*C in just about 20-30 mins. I have shutdown setting in my BIOS for max temp. 70*C.

I have changed and replaced my CPU fan and heatsink, but problem still exists.

What is the max temp for AMD Phenom II and can any suggest what I can do to resolve this heating issue?

Thanks.

@All, I found the actual reason for this, It was due to dried up Thermal paste. I added new Thermal paste and Replaced the Heat sink and All seems fine from then.

Thanks for your help. – Chetan Sharma – 2015-09-23T11:38:40.787

This question may get closed in its current format, I've made a change and I hope to keep it open. If you don't like my change, you can roll it back. – Dave – 2013-04-08T07:47:58.313

Your computer overheating has nothing to do with your migration to a 64-bit operating system. Sounds like you should look at the typical reasons a computer overheats ( dust, old thermal paste ). – Ramhound – 2013-04-08T12:12:00.143

Thanks Dave Rook, I really need to solve this problem, I am unable to operate my system form last couple of weeks. – Chetan Sharma – 2013-04-08T18:07:30.270

You probably shouldn't allow much higher temperatures. 70 is max according to AMD, for what it's worth.

I doubt that 64-bit windows is to blame. Even if windows made your CPU run at full load constantly, it still shouldn't go past the thermal limit.

Make sure that:

The heatsink is attached properly.
You are using a (decent) amount of thermal grease. The size of a grain of rice usually works well.
The fan is spinning freely.
You have decent airflow in the case. Try running without the side panel for a while to see if airflow is an issue.

It's fairly important, but there's no need to be fancy. http://www.dansdata.com/goop.htm

Make sure it is not a hardware error - may be your cooler went loose or its thermal grease dried up. Such things always tend to happen after OS reinstall and then you scratch your head a lot. If this doesn't help, check if may be you have switched off all powersaving features in BIOS. If you do, CPU would heat as if constantly under 100% load.
