Stulid Tested all of OcUK Thermal Paste Range

So I'm going to need thermal paste for my GPU as I'm installing my EKWB GPU block on it shortly. I've currently got Artic Silver 5 to spare from my CPU installation, is this going to be ok to use? I've heard people talking about wanting "non-conductive" stuff in various reviews / guides for installing the blocks; so just want to get some clarification as to whether I need a different paste - and if I do, what should I go for?

AS5 is capacitive so not something I would use as there are lots of small components around the GPU die on most cards.

MX-2/4 is fine, Gelid extreme, Noctua NTH1 I hear is good and I have also used Prolimatek PK1/2 and like those.
 
What are any of you guys opinions on what would be the best thermal cpu paste to use on my setup with the Skylake i7 6700K cpu and the corsair H80 closed loop cooler (only using one fan on the rad, no room for two fans in my very small itx build) ?

I will be trying my best to overclock the cpu, so need good decent temps.

The H80 comes with paste on but I have been told its not very good paste although I could be wrong, so thats why I need to try and find what would be best paste to use for these items and my requirments.

Thanks guys, please let me know, cheers :)

It comes with a silver based paste, its fine.

Buy some newer fancier paste when it comes time to remount the cooler whenever that time arises.
 
thanks for this however, any advice on to spread or not? i have been reading so many different ways of applying but which is the best?

If its a large CPU such as Haswell-E then spreading can be good to make sure all parts are covered, but with Haswell/Devils canyon/Skylake I just do the blob in the center and let the clamping force of the heatsink spread it out.

Video below shows various methods,


Cross method looks best.
 
Regarding Haswell E and paste, the small hole you see on the ihs of theese chips, does it matter if it gets blocked with paste? Fitting a new cooler earlier so had to get a fine brush and tease out a drop from this hole. MX4 so shouldnt cause any conduction issues if any got inside.

I've never had my X79 or X99 CPUs die from paste getting in the hole, I read ages ago its used to fill with glue and bond the heatspreader to the die (but then I also thought they were soldered) so if the hole is full of glue the chances of paste getting to a important part is 0%.
 
Given that the Gelid isn't available in the shop - what's the current best-of-class for ease/performance for a 4690K?

Thermal Grizzly is.

they do a few for different types of cooling such as Aeronaut = Air, Hydronaut = water, Kryonaut = sub zero.

I dont see why you cant use Aeronaut on water or visa versa though.

Kryonaut is designed for subzero and doent freeze and crack easily.

Basically its what all the pros use to set records these days.
