The block that is only in fractions of degrees inferior to the Kryos XTÂ´s cooling ability is the EK Supreme HF but keep in mind that the EK compensates this marginal tempreture difference with slightly less restrictivness than the Kryos XT and should therefor be prefered for the use in a full single loop.
But be aware! Recent reports have shown that more and more people are having problems with the Nickel Plating of the EK Supreme HF Full Nickel.
So if you would like to choose this block go for anything without Nickel in it.
The best price/performance/value ratio block would be as already stated the Rasa.
It will be some degrees inferior to the top blocks but makes up that lack with a reasonable price.
Then there is also the Apogee XT ....it is based on a very similar concept as the Kryos XT that is why that block has also a fair amount of restrictivity but after all still does not reach the KryosÂ´potential cooling performancewise.
I would rank this block on 3.) after the Kryos and the Supreme HF.
It performs slightly worse than the Supreme HF.
This block is prefered by the most because of its unbeatable mounting system.
And for older models that still fight their place in the upper league I would count in the
HK 3.0 and the Koolance 360 which both provide great flow and similar cooling ability to the Rasa.
In conclusion if you were to choose one of the blocks in the upper range I would recommend you to choose according to looks , mounting system and requirements of your loop(flow,dual or single,etc)
I myself have the EK Supreme HF Full Nickel but sending it back because of the possible Nickel flaking issue.
In return I will get the Kryos XT because I want a high performing Nickel block with no possibility of any issues.
If you are an extreme enthusiast I am sure you will want to get the max out of your block.If you additionally have a strong enough pump like the MCP 655 I would recommend the Kryos XT even in a full single loop.
When engaging watercooling you should not be trying to save 20 $ especially not on the CPU block.
If you would like more flow with the disadvantage of a rather old and in my oppinion ugly looking mounting system (cause the screws ofthe rev.2 are too long) go for the EK Supreme.
Most people use this block and it is great!
Just bare in mind the Nickel problem history.
For some degrees less but an incredible mounting system and somewhat restrictivity go for the Apogee XT also a great choice.
Anything else is in my oppinion unworthy of being mentioned if the factor of looks is disregarded and only absolute performance in 2 degree range is put into consideration.
My personal ranking measuring a.)cooling performance,b.)restrictivity,c.)mounting sytem,d.)value/price ratio
a.)best cooling performance on the market
b.)roughly 15% more restrictive than the others at least not enough to actually make a difference
c.)the mounting system is fair....not as sophisticated as the Apogge XTÂ´s but still far better than the EKÂ´s
d.)the price is reasonable seeing as it is Nickel plated Messing
2.)EK Supreme HF
a.)close to the Kryos XTÂ´s tempreture results but still phenominal.
b.)best flowrate results with still the most restrictive jet blade 1 but not enough to make a tempreture difference measurable.
c.)very old and primitve mounting system you will have to measure the depth with a ruler to ensure perfect conductivity of the block.
d.)depends on the version Full Nickel is the most expensive and the least recommended by me cause of the flaking issue any other version has a reasonable price range.
a.)worst tempreture results within the ranked blocks but 1-3 degrees difference at most.
b.)its structure and therefore restricitvity are very similar to the Kryos XTÂ´s
c.)best mounting system I have ever seen on a block it promises perfect conductivity and makes up for the missing 3 degrees in cooling performance.
d.)pricing is again reasonable for a block of this caliber in my oppinion.
The remaining blocks that perform 3-4 degrees worse than the ranked blocks but can still compensate that disadvantage with a very reasonable price are in my oppinion the
They are most suited for beginners and people who do not have sufficient funds.Edited by Kung Pow - 3/13/11 at 10:27am
