Hi All
I ordered Thermalright Ultra 120 Extreme HS and Arctic Silver 5 thermal compound
The Ultra 120 HS arrived with thermal compound included
Thermalright The Chill Factor
Iam confused !!
Which one to use and which one better ??

Any help please

Id say go with the AS5

I dunno, the AS5 technically has to be re-applied every 6 mos. I'd probably stick with the stuff that came with the cooler. Or would have bought MX-2 to begin with :\

So one vote for thermalright and another for AS 5
AS 5 Has to be reapplied each 6 month ???

If you are going to change the processor, use arctic silver. I reapply arctic silver once every 2 years. If you are just going to use that processor, go ahead and use the thermal pad. The thermal pad has paraffin, it melts and fills the gaps. It is very hard to remove once it is settled in.

AS5 every day of the week and seven times on Monday.

I might upgrade processor within a year or so
I think I'mgoing with AS 5

AS5 is one of the more popular paste out there, but it isn't the best. There's definitely better TIM out there, but I'm now wondering if AS5 can last longer than the rest.

Here are some benchmarks on thermal grease:

While that review is very ambitious, it specifically said there was no cure time, which could make the whole test worthless. This may be a good thing for the AS5, but perhaps there's other pastes that can perform even better with the cure time.

I would use AC5. I still have a tube of it from 3 years ago.

Which brings up a point. Does thermal paste expire? Do they lose their performance on the long run?

My initial guess is yes, after all, some paste do get hard and crusty after a long time.

....and the silver can separate. I think they recommend storing it tip down in the fridge.

Yeah, 99.999% of it is silver. The rest isn't. So performance decrease?

99% is the purity of
