HK rev.2.5 vs. 3

Hi guys, I havent been using watercooling for ages, but would like to do so again, maybe chilled water... (have all the stuff)

I used to use rev 2.5 HeatKiller on LGA775...
Question is; is rev.3 better, and if yes, how much better????

Bonus question is; will mount from rev3 work on rev2.5 ?? I want to use LGA1156

Thanks,
Marc

Hey Marc,

Don't how much the difference is but the rev 3 is really hot here atm while nobody really cared for the former revisions of the Heatkiller.

It's supposed to be about 2ºC better than the FuZion rev 2 to give you an idea.

I think rev3 has it's own mounting and there are backplates available for socket 1336, don't know about 1156 but a little google search will help you out.

By the looks of it i'd say it's the same as socket 1336:

Design appears identical on the inside, difference is that this one has some metal with heatkiller 3.0 in steel on top... :-P

They're very different (no bow, no distributer plate, not very fine cooling channels, much smaller size). The HK 2.5 was one of the worst blocks for quad cores.

Looks can be decieving my friend.

I just looked at the inner design, ok, I admit, huge difference, seems I will order a new block =) (and a regas for the mach II while Im at it)

A correction to my previous post. The HK 2.5 does have a distributor plate. It's integrated into the mounting "wings". The block consists of two halves. One upper and one lower with the mount sandwiched in between.
