i have an XT but i really like the flow for EK HF
@justin.kerr: I used bitspower 7/16 compressions and 2 fit fine on the hf, (if that's the block you're speaking of).
2 7/16's don't fit on the xt.
My block just arrived and I got two Feser 3/4" OD compressions on the Supreme HF plexi, I doubt the spacing is any different on the HF CU.
I was also surprised to see that the top is noticeably thicker than that of my Acetal Supreme (non-HF). Is this just because it's plexi or was was it done to increase the rigidity of the top over that of the original Supreme top?
I wonder whether Vapor will be able to show a real performance difference (as in more than 0.5°C) between the standard and the copper tops on the Supreme HF... I was gonna get the Cu but I like the looks of the plexi version much better and finally ordered that one then.
sorry for not being clear, here is the original HF, and the new CU HF
CU will not fit.

I love this block, but people with cases that dont have a hole cutout for the backplate on their mobo tray might have issues. I've got a Cosmos S and the metal holding plate was shorting the whole thing out, so a slight mod was needed. (hope you guys understand what i mean!)
Just a heads up.
Should I suppose the performance would be the same between the Cu edition and the original HF?
I mean, the different hole position does not change the flow path, right?
As for Nickel vs. Cu vs. Gold vs. Acetal/Delrin....the general expectation is that there's no performance difference (outside of natural variation). It's hard to say for sure without testing, but in my tests (sorry, still haven't published some of the small-fry testing I did for s&g), the Supreme DID benefit by ~.7C from a copper top. My hypothesis is that the bow was improved by the increased structural strength of the metal top vs. delrin. That said, the Supreme HF is the 'tightest' block I've seen to date, so I don't think there's as much to be gained by increasing the structural strength. The change of the inlet doesn't seem like that big of a performance changer since it looks like the inlet chamber is identical.
Plating does add only a few microns of material, but the basic fin/channel structure is already really small and a few microns can (and probably does) have some sort of impact; without testing it's hard to say if it's negligible, negative, or positive. The fact it's an inferior thermal material isn't as much of a concern, IMO. This is a particularly difficult thing to test--you need to test a base, then plate that very same base and retest it for any sort of "what does plating do" data.
As I've said before, Roundup #2 is coming to a close....I have the CPU-360, some of the unpublished data to release, and skinnee just convinced me to throw the Alphacools into Round2 before I wrap it up. Hopefully for Roundup #3, I'll be able to start off with XT vs HF vs HF-Cu vs HK vs CPU-360 vs whatever else might be deserving to be grouped into the elite. :)
Those full copper blocks .. how do they look after long periods of time without any polishing/cleaning? Or i should go only nickel if i want to go least maintenance route?
My HK copper is scratched and looks a little beaten up over time, and isnt the prettiest component in my build as of now. Since most other components are black and silver in mine, with blue board, copper kinds looks old as well. Had I to do over, I would have gotten nickel coated, for aesthetics and durability. But color schemes and preferences differ, and some may be happy to polish. I have the acetal supreme hf, but thinking about trying nickel just for kicks.
And I echo the nickel being not that important. While it is not practical/easy to try and test nickel coating effects on temps of waterblocks, I can tell you the effect of nickel coating on my cpu. My i950 was flat over middle 3/4 of it, with just subtle concave shape when accounting for extreme periphery. Prior to lapping, I tested several mounts with calibrated flukes/temp probes measuring all intake ambients on rads, water temps, and recording all core temps. Then, I only lapped until nickel was gone, the shape looked exactly same. The temps before lapping and after were exactly same, less than 0.1C difference. Not same as testing on waterblock, as their are many differences, but cant imagine temps being that much different. And if Vapor has tested them, and nickel/copper are within typical slight variability block to block, sounds like performance wise, not relevant any way you look at it.
I remember now. I was talking to Shane and he suggested to have holes for the fittings more centric, and missed that. We'll make revision with next series definitely. The fittings must have about 26mm diameter, right?
Looks like fittings for 19mm OD tubes, so they are 27mm OD
Yes, 26 mm :)
New revision... hm... 4-6 weeks.
And no thermal performance difference.
