Reapplied Thermal Paste.....

post #1 of 6
Thread Starter 
So I just reapplied my thermal paste, and I'm reading literally 10c lower temps across the board.

I'm wondering how long I should let the new paste "set in" before it's safe to run an overnight stress test.

I have CoreTemp's overheat protection enabled -- but this is a situation I haven't been in and I dont like relying on software to prevent my CPU from frying!

Depends on the paste, some paste has some burn-in time. Others don't. I'd give it 1 or 2 days, but again, it depends on the paste you use.

Depends what thermal paste it is, Arctic silver 5 needs 200 hours to "break in" and get the best performance, others need less and some need none.

But you should be fine to start stress testing.

Yeah usually I just give it 10 hours load/10 hours shut down/10hours load and so on for a few days.. Great way to break in paste!
But as others have said some paste needs less and even no cure time when something like as5 is recommended 200hrs.

EDIT: what paste you using?

IME and that of many other folks Arctic Silver 5 only drops ~1C after 200 hours of thermal cycling so it's a moot point. You can run stress testing immediately with any of the TIMs. A change of 1-2C is all you'll ever see if that.
post #6 of 6
Yeah, it should never be unsafe, as even the TIMs that benefit most from thermal cycling/curing are only going to improve a few C from a fresh application.
