EK Supreme and Koolance CPU-340 Compared to The Competition

Cooling/Water Cooling by KeithSuppe @ 2008-04-16

Today we add two new blocks to our previous roundup, newcomer EK Supreme out of Slovenia and Koolance replacement to their CPU-330 the CPU-340.

EK Supreme

Great things from Slovenia :

EKWater blocks is relatively unknown in the USA was founded CIRCA 2003 by Edvard Konig whom chose his initials as the company name. Early CPU water-block prototypes were given the moniker EK-1 ~ EK-4 and it was the latter in the first thumbnail (from left) which became the first retail item. Moving to the next thumbnail and water-block we have the EK-6 introduced as a "serial" water-block. In 2004 straight channels became "waves" which eventually led to the EK-WWA (Wave Water Accelerator) seen in the second to last thumbnail to the right. The curved channels in the wave design then shrunk, culminating in the EK-MCW (Micro Channel Wave). Far right..

Below we find the EK supreme sans its universal mounting plate. The block itself measures approximately 50mm x 50mm and is not much larger in size then an Intel IHS itself. Of course if the block is designed appropriately it does not need to be any larger then the IHS and in some designs it may be slightly smaller.

Disassembled the EK Supreme has some unique parts. The mechanics of the design cannot be pigeonholed as it's not an extruded pin, nor a mini-jet with corresponding cups.

With the top-plate removed and flipped I've placed the slotted accelerator plate in place. This is to exemplify how the water stream originally enters the inlet and is immediately divided across the length of the plate. Back pressure from such a design would require a high pressure pump if you want optimal performance from the EK Supreme.

The base-plate below with its many "micro-grooves" represents a unique technology. The plate is situated in the photo to compliment the position of the slotted plate in the photo above. The high pressure streams impinging on the micro-grooves below run perpendicular for greater turbulence and heat absorption.

It's not an ontological leap to extrapolate where the designer became interested in the benefits of micro-grooves and in the EK-Supreme it's simply been taken to its extremes. Micro-grooves en-masse takes full advantage of thermal conductivity in reference to Heat Transfer between two objects. The formula represented as Heat transferred in time involves the following: Conductivity of the objects, Area, Temperature and Thickness. I found the design to be a refreshing twist on thermo-dynamic theory. .

And of course there's the base finish. Laying a metal slide ruler across the EK Supreme base proved to be just about perfectly flat. The finish was superb another mirror image.

This review of the EK Supreme also put it in the lead!

A most impressive block indeed, but techpowerup didn't put on very stiff competition (best = TDX block which in our review is only average).

Other than that : great work Keith : you've rounded up what I believe are almost all the best cpu-blocks out there. I would like to see the Alphacool NexXxos highflow in between the others though, I own it myself and I wonder how it performs in comparison.

thanks for the review!

would be interesting to see how dtek fuzion + 4.5mm nozzle would fair amongst the current results

Keith your stock aircooling results are very impressive, below 60°C with overclocked Q6600 @ 3Ghz...

we've seen 90°C in closed case with stock Intel cooling at those speeds: http://www.madshrimps.be/?action=get...&articID=5 96

Yes, at 1,52Volts... A Q6600G0 can run 3Ghz @ stock voltage (or close).

Arctic Freezer 7 Pro + Q6600 G0 @1.20v @ 3.20GHz had Coretemp readings of 55-60c. Ambient roughly 23.3c. I think it speaks volumes about that test rig setup

Nice review, will have to keep my eye on both waterblocks. I wonder what will be out for Nehalem...
