Best Waterblock Kryos XT vs EK Supreme HF

post #1 of 26
Thread Starter 
I have recently sent my Aquacomputer Kroys XT back for the EK Supreme HF Full Nickel.

The reason for that was mainly that the Supreme performs nearly equally to the Kryos with much less restriction.
It is very funny but in some reviews the EK performns better than the Kryos in other ones it´s a ty and sometimes the Kryos wins.

I wanted to bring some clearance into that subject and really determine the winner amongst those two, judged by restriction,accurate data and documention of cooling performance(with ambient temps,water temps, possibly Delta T),looks,and acutal heat transer)

We have a lot of reviews that still do not state an accurate decision between the two and who is really best and mostly have not tested so that all the advantages of both blocks could be exhausted.
Fore example in Vapors Review of the Kryos XT and EK Supreme the EK won but the review did not show any water temps or ambient so the results could not be counted absolute.

I have 2 pictures attached of Vapors Review which show the EK´s and Kryos results ...and the EK wins due to higher flow ...like I mentioned before no ambient and water temps or Delta T temps were shown in this review that is why I cannot take them for sure.
Then there is one other picture that shows the table of a review made by a german company called Pc Master...here you can clearly see the Kryos has higher water temps which means the heat transfer was better and the Delta T temps are lower than ones of the EK even though the EK´s CPU temps are lower. The ones that wonder why the Kryos wins this one even though his CPU temps are higher: the Delta T values just negate the influence of ambient temp and other disturbances that could corrupt the cooling performance of the block so it is the most accurate value and is determined by CPU temp - Water temp .


But there are too little reviews that actually feature the EK Supreme HF vs AC Kryos XT fight at its peak.

That is why I want to rely on your experience and your knowledge to make the decision abouth which one is the winner.
EK Supreme HF VS. AC Kryos XT
Comparison Boundries:restriction,actual cooling performance,looks,mounting, etc....

Tell me what you have experiened or heard and most importantly what you thinl.

Cheers

There are some scattered European reviews where the Kryos series beats the Supreme HF in temps, but the differences are so small you may rather go for higher flowrates. Of course, this is ignoring the .925 silver-based Kryos, which is hyper-expensive, nobody's tested that yet, but it's supposed to be a few degrees better than the normal Kryos.

I don't know where you got the first one but I'm having a hard time believing those Delta T numbers... VERY hard time. The latter 2 I assume you got from Vapor's review, and without Delta T figures those aren't of much use.

From what I've gathered over time, if you're after the absolute best temps regardless of exactly how much better they are than the next one down, get the Kryos. If its availability, inferior mount system, and restriction are of no concern to you, then it should be a sure thing. Otherwise, EK.

I only have one big loop in which of course restriction of the blocks is of much concern than in seperate ones.

Also I did not know the mounting system of the Kryos is even inferior to the EK´s.

I already went for the EK Supreme HF Full Nickel since it is the one that had the best results with Plate 1 even better than the Full Copper version to my surprise.

The Kryos superiority in cooling performance to the EK´s is shown to be less than 0.3 degree most of the time and that is also only the case because like you said the Kryos is much more restrictive.
Because the EK performs just as well (if not better) with much less restriction I think it is just the better guess especially for 1-Loops.
But the mounting system of the EK is ver often mocked and classed very primitve and ugly.

But I opened this thread to get all of your oppinions and experience too so post people

I would choose the Kryos for dedicated CPU only loops and the EK for multiple block loops.

But that's just talking performance on the perfect mount by an experienced tester.

I would seriously look at other things like mounting mechanisms, etc. I would even consider lesser performing blocks that have better systems than these two as I feel that even more important than fractions of a degree.

An improperly mounted block can cost you several degrees in performance so it's really important to have the perfect mount. Swiftech has the best mounting system I've used. Something with a good backplate system and something that has thumb nut stops for equal and perfect mounting pressure on all four corners is a big bonus.
