EK Supreme CPU Water Block

Testing Methodology

Testing Methodology

For the testing phase of the review I have chosen to test the EK Supreme against a number of well known water-cooling blocks: the Swiftech Storm G4 rev. 2; the XSPC X2O Delta, and of course the D-TEK FuZion.

A quadrella of quad-cooling goodness

A Laing DDC Pro pump with OCLabs alternative top will be used to assist in making a comparison. I shall be looking specifically at pressure drop, flow resistance and cooling performance from within a CPU only water-cooling loop. I will be running the Laing DDC Pro pump at 9v,10v, 11v and 12v and the pressure drop and flow of the pump will be noted. All tests will be run 3 times to ensure the elimination of any oddities. I have included the setup details below:

Pressure Drop

For the pressure drop test I used a 25L portable water container filled with 20 litres of water, with a 1/2" plastic threaded barb placed in the bottom to represent the reservoir. A stop tap was inserted immediately after the 1/2" barb to allow for a faster water-block change. The True-Flow pressure meter was used to record the head pressure per 1 minute testing cycle. The pump was primed and let run for a short period to ensure that no air bubbles were left in the loop.

The first run made was with only the pump and pressure meter included in the loop and the water pressure noted. Then for second run the EK Supreme waterblock was included into the loop and the drop in loop pressure recorded, and the same procedure was done for each of the water blocks.

* 1 x Laing DDC Pro pump with OCLabs alternative top @ 9/10/11/12v
* 1 x EK Supreme; XSPC X2O Delta; Swiftech Storm G4 and D-TEK FuZion water block
* 1 x Powertech variable DC power supply (quoted accuracy /- 0.2V)
* 1 x Multi-meter
* 25L portable water container
* 1 x Glycerine filled True-Flow pressure meter. (kPa/PSI)
* 1/2" ID XSPC tubing
* 1/2" barbs
* 2 x stop-tap fittings

Flow

In a similar test to the pressure drop testing above, the flow test will highlight just how much the waterblocks restrict the natural flow of a water-cooling loop. Utilising a very simple setup consisting of a pump, I/2" ID tubing, water blocks, bucket and a stopwatch we will see how far removed from the absolute flow of the pump, that the water blocks hinder flow. Incidentally, this is the same way that we test GPU blocks in past reviews...hence the included image below. Running the pump into the bucket for one minute and then measuring the amount of water pumped will be the 'absolute flow' of the pump. Once again the pump will be run at 9v,10v,11v and 12v.

To calculate the flow-loss or restriction of each waterblock, they will each be included into the loop (one at a time) and the same procedure followed. The flow rate will be recorded in Litres/ hour. All simulations will be run 3 times each to ensure uniformity of the results and an average then taken.

Flow testing

Loop Simulation and cooling performance

I have decided to impliment a control setup for the testing phase of this review. In doing so I have replicated a CPU only water-cooling loop similar to that in conventional water cooled setups, but also one that should return consistant and unbiased performance results. The EK Supreme and other water blocks performance will be assessed at the Laing DDC Pro's operating voltage of 12 volts. For each run, the pump was allowed to run for 20 mins to ensure the evacuation of all air from within the loop. The temperatures were taken at 30 minute intervals to allow them to 'settle'. Two instances of ORTHOS will run simultaneously in order to simulate load.

Test setup

Arctic Silver 5 was used as the TIM for testing all water blocks in this shootout  I have recorded temperatures at idle, load and and an overclocked loaded state; all temperatures were taken using Core Temp 0.95.4 beta and water/ambient temperatures were taken using a common household mercury thermometer. The mercury thermometer was allowed 5 minutes to aclimatise to air and water and then the temperature recorded. The setup used has been included below:

* 1 x Laing DDC Pro pump with OCLabs alternative top @ 12v
* 1 x EK Supreme; Swiftech Storm G4; XSPC X2O Delta, and a D-TEK FuZion water block
* 1 x Powertech variable DC power supply (quoted accuracy /- 0.2V)
* 1 x Multi-meter
* 1 x Toyota Camry heater core
* 1 x Scythe Ultra Kaze 2000RPM cooling fan
* 1/2" ID XSPC tubing
* 1/2" barbs.
* 1 x Intel Q6600 SLACR G0 stepping quad-core processor
* 1 x ASUS P5B Deluxe wifi/App motherboard (bios version 1101)
* 1 Gigabyte 7600 graphics card
* Logitech generic mouse
* Logitech G15 keyboard
* 2GB OCZ PC2-6400 Titanium RAM
* Antec NEO EarthWatts 500W PSU
 

Please be mindful that all water block mountings were done so without a back plate. Hypothetically, the findings reported on the following page could be potentially better if the ability to screw the water block right down were available at the time of testing.

OC3D has put the new EK Supreme through its paces in an effort to see if it can usurp the title of 'Cooling King' from the D-TEK FuZion.

I like my Supreme's with lots of anchovies and chillies.

Nice job as normal PVs.

Fantastic looking and performing block!

Thanks for the feedback Ham Yeah the block is simply gorgeous...I can't wait until the plexi tops arrive

Nice review PV.. Great block

Holy moly, didnt expect that much of it

Tempted to invest in one of these now

Ooooh this looks interesting now..

I really am looking forward to you Fuzion nozzle kit reviews now against the EK Supreme with different plates.

I assume the Swiftech 655 has enough power to deal with the restrictiveness of this block? I'm only cooling my cpu at the moment with a PA120.3 lol

99%, jeez. Move over Dtek.

Ahhhhhhhh I was only searching for a review of this block last night.. I love you!!!

Ok perhaps not love but you are pretty good

I'll read this when I get back from Bloc Party tonight

SOOO glad i waited and ordered one

Great review PV as always.

I'm looking forward to EK bringing out the new Accelerator plates for this block so we can have a heads up with the DTEK again but this time both with the aftermarket performance packs

They shall be heading your way shortly once they are in production

Thanks all for the feedback on the review and I'm glad you enjoyed it

well its good to see some hard evidence that shows how good this block is...

Wow, nice review!

I'm kinda curious how it performs in comparison with the Nozzle kit from D-Tek. Still thinking about buying the nozzle kit or the EK block...

11-01-2008, 13:04:13

FarFarAway
I believe you will be seeing this fairly shortly

12-01-2008, 06:34:43

Sp33dFr34k
Sure hope so

In the meantime I would like to get a nozzle kit as they're not that expensive, but they're kinda hard to get a hold of it seems.
