March 2011 CPU Block Revisions

Over the past three weeks both Swiftech and EK have announced modifications (in one way or another) to their flagship CPU blocks. Koolance got to the punch earlier with releasing the CPU-370 and we figured others would be releasing tweaks and new blocks as well, but that is like predicting the sun will rise tomorrow morning.

Swiftech XT Rev. 2

From the details we have, the Swiftech XT gets the biggest overall change with a completely new top for the XT. The revision is aimed purely at reducing restriction and maintaining the thermal performance. The original XT was quite restrictive when compared to blocks like the CPU-360 and Supreme HF; Swiftech is promising to cut restriction in half for Rev.2.  The base is unchanged and the tops will be available separately, so existing owners can purchase just the tops. The other option–which has been suggested in forum discussion–is to give it a go yourself with a Dremel. We will see the XT Rev. 2 hit our CPU block testbed in the near future.

The trend of reducing restriction of their blocks is expected to hit the MCW80 as well. In fact, I have a feeling we will see lower restriction across the board for Swiftech moving forward.

EK Supreme HF mounting system revision; Rev. 3

EK announced a reworked mounting system for their top-tier Supreme HF. We say it’s about time. It’s not a secret: we are not fans of the original Supreme HF mounting system. The revised system still requires some assembly but tightening to the ideal mounting pressure is no longer a blind adventure.

The revised system still uses a basic backplate, but the long screws are now split into three.  The first piece is through the backplate and mounting holes. Top side of the board is a threaded coupling holding the backplate in place, with the block in place you finish the mount with a spring inside the capped thumbnuts. The cap limits and evens the amount of mounting pressure applied.

To offset the increased cost of including the improved mounting system with the block, EK will no longer be shipping alternate injection plates with Rev. 3 Supreme HFs; the only plate to be included will be the top performer, P1.  The other plates will be available for purchase.  Additionally, Arctic Cooling MX-4 is being included instead of MX-2.

Hello SL, interesting info for me here since i own an ek supreme hf full nickel, but i’ve got a question, do you think the mounting pressure will be better
with this? and do you think this kind of mounting system will help to spread better the TIM? So the real question is, will the supreme hf rev 3 perform better? I hope they will give the opportunity to buy just the mounting system to “upgrade” the block. Later!

It shouldn’t improve the maximum performance you can get out of the block, but it should improve the ability to get the maximum performance (if they have the pressure right) and should definitely improve the mount consistency.

New mounting systems (in both silver and black) hopefully will be in US retailers pretty soon (for ~$15, based on the prices at EK’s online shop).

Yes, thanks for the heads up. Just checked it out and they look much nicer! Sidewinder has the silver ones, but I can’t find a U.S. vendor that has the black ones. Will keep looking though.

I really like the new looks of the EK mounting system. Hopefully, they will also make it in black because I would definitely buy that.

They do make it in black! On their website it costs a dollar more and isn’t available yet, but it’s there :)

The black is nice looking too, definitely prefer it to the silver.
