Masscool G751 Shin-Etsu Thermal Interface Material

This is the same stuff that Corsair puts on all their coolers. A to H series, at least up to the H70. I've heard they went a different way for their 80 and 100 series but I've seen no substantial reports confirming or refuting those claims.

Corsair is a re-brander however. They don't make a lot of the stuff they sell and have just undergone a change in manufacturer of their Hydro series. So that may mean that the new manufacturer is not using G751, which to me is a real shame. Outstanding TIM. When you mount the Hydro block its a good bet if your temps aren't looking optimal, you can remove the pump/block spread the tim out to fix any bare spots and re-seat. This means with ~8hours of burn in you don't have to wait a prolonged amount of time before you can fix it. It's almost instantaneous compared to other TIM on the market.

AS5 for instance has a 200 hour burn in time. How do you like waiting over a week before you can really mess with a re-seat when your temps aren't optimal? I like AS5 but if you're in your system a few times a month or couple months those weeks adds up in a hurry. Not so with G751.

I had the H50 and while the TIM was a little on the thick side the temps were pretty good. My average temps @ Idle was 29-31c. Under Load average temps were 43-47c while Folding. That was with a Push/Pull fan setup with shroud between the Push and the Radiator and my 955 BE with a minor lapping.

What's more is that I never once spread my G751. I apply a small to mid size pea amount to the center of my CPU and let the weight of the block do the spread for me and give the heat sink a minor twist and lock it down. I've never once had to do a re-seat because it really is that easy.

I can't recommend G751 enough. So much I'm organizing a group buy for 3g tubes of the stuff.
