Can anyone help please?
Im having a problem with my CPU overheating at 70oC when encoding video and the computer shuts down. I was having the problem with the stock heatsink that came with the processor so upgraded to the Zalman CNPS12X today and its still the same. I did have 16GB RAM in but had to remove 2 sticks to accomodate the Zalman

I was going to upgrade the graphics card cause as you can see its only a cheap one but i dont do gaming so it suits the purpose. If it was required for video encoding then i would upgrade but i read everywhere that doing video uses your CPU to the max not your graphics card ... hence the upgrade on the heatsink but im at a loss now as to what to do about it.
The CPU isnt overclocked and never has been. All components are 12 months old with the exception of the Zalman but its only recently had a problem cause ive only recently wanted to encode video

The program i'm using is DivX Plus 8 Converter ... could it be software or is it definately Hardware? Listed main specs below, Any help would be appreciated.

I was using Arctic Silver 3 but seeing as the Zalman heatsink came with some of its own ZM-STG2 Super Thermal Grease i thought i would give that a try.

You think the thermal paste could be my problem?
 
The proper question there is how did you apply said paste. AS3 should be decent, but if you applied it sloppy then it will not do its job.
 
I have always applied a thin layer across the surface and never had any issues but i believe the preferred and more efficient way is a pea size dot in the centre and let the heatsink disperse it when seated so i will try that way and see if it helps
 
There are few TIMs that are supposed to be spread before applying the heatsink. This is your first issue most likely (air bubbles).

Pea sized in the center for non direct heatsinks. If it is a direct contact heatsink, then put a thin line on each heatpipe and then apply heatsink as usual.
 
Thanks a lot wolfeking ... encoding as i speak and cpu not going above 40deg ... cant believe it was something so simple .... greatly appreciate your help :)
