What thermal paste do you use?

[Vacsol]

I bought some Arctic MX-2 for my full PC upgrade HERE

What thermal paste do you guys use in your water cooling setups?

maybe I should use mayonnaise instead

[Henleyz]

Arctic Silver 5

[Vacsol]

Obligatory

[flibberdipper]

I like to use NT-H1, but most of the time I use Arctic MX-2.

[Jade]

Arctic Silver 5.

[Entropy]

MX-4, usually. I have some Shin-Etsu on at the moment. It was free.

[TheSLSAMG]

Noctua NT-H1, looking to try new compounds.

 

From what I see, I should try to use AS5.

[Maxibonbits]

Whatever came pre-installed on my cooler.

[VG Docs]

Obligatory

 

Lipstick above Rosewill thermal paste?

[BloodWithIce]

industrial silicone compound. 
$2.50 25g 

[ForsakenLive]

According to the chart I should start using Mayonnaise

[Aniallation]

Whatever comes with the heatsink. lol

[Hecknologist]

NT-H1. While it says AS5 is good in this test, I've had some very different results with it and in most cases doesn't do very well at the extremes. I'd check other results before jumping on board with it.

Also it's worth noting it's slightly electrically capacitive and can short out traces.

Swiftech TM2

GELID GC-EXTREME

 

Apparently it's a rebrand of the Phobya HeGrease Extreme. It works pretty well though, it shaved a few degrees of my CPU temps.

[Enderman]

MX4

Those are idle tests...

You see a much larger performance delta under load...

 

*facepalm*

doesn't make it any less funny

[Enderman]

doesn't make it any less funny

But it makes it flawed, which defeats the point of a test...

[DigitalHermit]

DeepCool Z5... Because I'm a cheapo...

[Peopie]

I use MX-4

 

I don't like AS5 because of its conductivity and slow curing times.

[Grrizz]

MX-4 or AS5 depending on what's on hand for general/rough surface/short term stuff and pro ultra for more long term/critical stuff though I do want to give Indigo Extreme a go on my next serious build

[connorpiper]

Antec Formula 7. 

Got it at BestBuy.

In the 34 range on that magical chart.

[Najuno]

I use AS5 and had never any thermal issues with it and I OC all my hardware as far as I can...

[Lays]

Gelid GC Extreme, Ic diamond 7, and coolermaster fusion 400.

 

I'm not 100% sure about that chart, I saw 2 degrees lower with the ic diamond than with GC extreme, and the GC extreme is quite similar to the CM thermalfusion stuff I've used.
