[Review] Round 2: EK Supreme HF

[prtuc2]

Ah speaking of gold, I'm planning on getting the EK Supreme HF Gold Edition. Does it come pre-installed with the P1 plate?
If not how would I go about replacing the stock plate with the p1? Would it void the warranty?

The stock HK Gold comes with stock plate which is P3, I also just swap it out and use P1. As warranty I don't know you can get Eddy to follow up on that.

[JASSAF]

Vapor did say that microchannel depth might vary with the Supreme HF, so both of your measurements might be correct for the block you actually have.

is unlikely that EK have done blocks with diferent Measures, i bougth the mine 3 weeks ago.

i forgot: the bottom surface of the channel is flat

[Eddy_EK]

The warranty sticker is only a proof that the block is leak tested.
If you remove it you still have the warranty on material and manufacturing.

Looks like the jet plate #1 is now the stock.

I've got Acetal/Nickel block last week (from reseller so must have been couple weeks in the warehous) and the best performing plate #1 was mounted in it.

Not sure though why the block screws are not black now (perhaps a brief shortage?), fortunately I've had Acetal/Copper couple weeks earlier with black screws so a quick swap and looks good now lol

Is the full cu revision for fitting 1/2 ID 3/4 OD coming any time soon? Trying to decide on whether to pull trigger now on non full cu or wait..

We will be offering a separate copper top only purchase that will have 1,5mm wider spacing. Available in about 2 weeks.

Anyone know if this test, and the HK 3.0, are with HT on? I didnt notice in the test writeup.

[Vapor]

All my tests are with HT on.

[Camaroz06]

All my tests are with HT on.

Thanks for the info

Awesome Eddy! Will that top work with all current HF variants? eg. Copper-Plexi/Nickel-Plexi/Nickel-Acetal/Full Cu Nickel etc?

And is the new top going to just be Copper? or will there be the Nickel plated variant top also? Thanks again!

Hi, New Copper top will be only different that the G1/4 threads will be 1,5mm further apart to support the biggest compression fittings.
Top will be in Copper and Nickel version.

Yes, we are, but the Germans who makes us tooling for the fittings are screwing us hard :S

Ze Germans! Hey, the tooling is expensive, but ze Germans have the best stuff. They're just ensuring you get quality stuff. I'm German

Which plate is the most efficient ??

Conclusion

Let's get something out of the way quickly: with (the included) Plate 1, this is the best performing block I've tested to date. Its restriction is very low and its thermal performance is the best at every pumping power (and at typical pumping powers, it distances itself by quite a bit over the XT). The only caveat is that it needs Plate 1 installed for it to be the absolute best, and that's not much of a caveat considering it's included hardware. I would actually like to see even more restrictive plates as options to see what else can be achieved from this block thermally (yes, I realize a blank is included, but home machining is not in most people's repetoire).

affiliate13: since some time EK changed preinstalled stock plate to #1, so new buyers don't need to change it anymore.

[affiliate13]

Yes i remember Eddy mentioning plans to do that.
Good new then this has already been implemented.
I would imagine then the block will be leak tested before shipping as before..but with the better performing plate.

I will be getting an HF when the new spacing model appears all being well.

I just got my EK Supreme HF Full Copper in from Performence-PCs. I cant really tell, but am I going to be able to fit compressions on here? Or will I need to buy some rotaries?

[longh]

You'll surely need to buy some rotaries.

Eddy promised a new revision that would be able to fit 3/4" OD fittings, but it seems to have delayed...

[Artemis]

Darn, was hoping to save some money. Oh well.

[Kilyin]

This is the way its supposed to be installed right? I noticed some people have it upside down...?

My understanding is that as long as it isn't sideways its fine?

Yeah, some people mount it upside down for easier tube routing.

[blazarcher]

Sweet! I've been waiting awhile for these new revisions!! Can I order directly from the site or do I still have to wait a few days (weeks) to get them.

BTW, JUST to make sure, the new CU edition will support BP compression fittings that have an ID of 1/2" and an OD of 3/4". xD

[scottk]

How far do you guys tighten your thumbscrews? It's difficult to determine how equal I tightened each one so I continued tightening until I could no longer turn them without excessive force.

I did 6 full turns once the block was flush with the cpu HS, and the thumbnuts contacted the springs. Tension seems adequate, and tightening more than that didn't improve my temps. Measuring the length of the compressed springs should provide a rough idea of "equalness".

[Blueking]

mounting of supreme HF. Does it matter what direction block are mounted according to install instruction from EK or flip block so inlet are placed 180 degres closest to ram slots ?

[jumper2high]

I've read in a few places that it's best to put the OUTLET hole on top, so that air doesn't get trapped inside the block.

[Nickel020]

On monolithic dies it shouldn't really matter, on 775 quad cores with their two seperate dies you might see more of a difference.
