Hello tom's hardware. My question is, if I'm removing my heatsink, and re-installing the SAME heatsink (different MOBO, same CPU) do I need to remove the thermal paste and re-apply it? It's only been on for about a week.
A perfectionist would clean the old off and reapply new. But in reality, you can usually get away with re-installing it as is if it has been that short of a period of time. If you don't have any on hand, try it and run a stress test like Prime95 and see what happens to the temps. If they rise too high, shut down and clean/apply new. But, if you have TIM available, there's no reason not to apply new.
Okay, the first link doesn't say (it says to clean if you're getting a new heatsink, but not what to do if you're re-installing a old heatsink).
The second (non-video) link says "every 2 to 3 years" so that's not what I'm looking for.
The third says to re-apply always, because you might get bubbles, but that's with non-spread thermal paste, so it's a bit of a different situation.
The next two are "how-to apply thermal paste".
The one after that is again, after 2 or 3 years...
And then the one after that is... this page.
So yeah that didn't really help much.
So, does that mean you're suggesting I do re-apply? I'd just rather not because I'm a wuss, and because I'm not sure I have enough thermal grease/paste/insulating material left for another application. How dangerous is the procedure - how easy is it to break the CPU doing it? I'm always shaky handling that thing!

The procedure itself is fairly low risk. Just don't drop the thing, touch the pins, wear a grounding strap, etc. I've been able to perform the procedure several times when switching between processors.. frequently. (I used up 2 tubes of paste, total. The new processor still works fine)
