Thermal paste...what's the best?

Thermal Grizzly Kryonaut I believe.

Its one of the better ones without going to something specialise like liquid metal type :S most thermal pastes are really close in realworld results though.

EDIT: I'd be wary of comparing AS5 results with other pastes based on most of the common roundups as they persist in ignoring Arctic Silver's application notes and applying it wrong - manually spreading it in the style that many of them do can very much compromise it's performance albeit only by 1-2 degrees. *bangs head against wall*

Thanks for that guys i'll get some for next time!
 
But lots of small improvements can end up making a big difference (look at Team Sky for instance). I'd say if for the original OP's sig setup, if you're only running a modern i5 at 3.2Ghz and you've got a decent AIO, you might as well get the value stuff as a few degrees temperature difference probably isn't a big concern to you.

Looking at the pastes OcUK offers, Thermal Grizzly Hydronaut will likely be about the right thing to go for. Just buy however much you need and you're set. And if you just want to try a small amount out, the 1g version is the same price as the 1g Aeronaut.
 
Been using this EK-TIM Ectotherm on my sons air cooled x79 pc and my x99 H2o cooled pc, temps have not changed at all gaming, etc.

EK-TIM Ectotherm at £3.99, gives good temps and easy to spread/clean can't be bad.
 
The difference will be single degrees, I'd get the best value stuff.

That is largely what I've done - used AS5, MX-4 and some TG stuff lately depending on whatever was convenient to get hold of and reasonably priced at any one time and don't really see any difference between them in day to day use.

Maybe a bigger factor if I was doing extreme OCing but not had much space for that lately :(
 
AS5 is fine. I think intake and extract fans are more important than choice of paste. You can have the best paste applied, but if the hot air is just building up in the case and raising the ambient then the choice of paste is totally irrelevant.

Obviously choice of heatsink is a major factor too... The bigger the better.

In fact, choice of paste is probably the least important aspect IMO.
 
For me it is gelid gc extreme. I've used mx-4, EK ectotherm, Arctic silver 5, ic diamond.

It has been the best so far. Not only this but it is very cheap aswell.
