XIGMATEK HDT-S1283 Rifle - 46c idle! help! - Page 2

post #11 of 16
I have an opposite view that you just might not have applied enough thermal paste. Unless you have applied the entire tube of 3.5g(?) and flooded the CPU socket (but that is another problem), a slight or even moderate over-application does not hurt temperature as any excess paste will be squeezed out when proper mounting pressure is achieved when you screw on. On the contrary, a slight under-application could lead to severe cooling deficiency.

Also considering that your Xigmatek cooler uses HDT (heatpipes direct touch), there are gaps between the heatpipes and the block and these gaps will take in extra paste. Note the red arrows in the pic below. Personally, I would first apply some paste to fill up those gaps and then apply a thin layer of paste over the entire surface of the IHS of the CPU.

By the way, Tjmax of E8400 is 100C.

Curing time is the time you need for the thermal interface to reach optimal efficiency.

Basically, you need to run your computer for a certain amount of time before the thermal compound reaches 100% cooling power.

The problem with AS5 is that it's curing time borders on ridiculous - it's on the site, and it recommends intervals of 2-hours with computer on, then 2-hours off until...I think it was 80 hours?

I could be wrong, best to check the site.

EDIT: It says 200 hours. But I'm also certain a good 90% of people that use it (who also have more experience than I in computer technology) ignore the 200 hour curing time.

I don't mean to insult you by this, but is your fan set in the correct direction? People make mistakes, and this could explain your temps as well as any thermal interface problems.

This does sound about right. i'll go in there again soon and see about throwing a bit more on there if it looks like i need some.

wow that is rediculous. If i'd known i would've gotten something else. was only 10 bucks though, no big. I'll work with it for now. Thanks for clearing that up!

Yeah, it's a little nuts.

It's okay though - if anything, that'll just mean your temps should drop as you use it more often

When you run out of AS5 though, I'd say try something that involves less hassle.

Definitely. Thanks so much!

Meantime, i'll keep an eye on it and see if i can get these temps to drop. I stressed it a bit in p95 and it didn't really shoot over 55c so that's good. At least load temps aren't getting insanely high.
