Hi. This is my first post on the OCN. I would like to present you our newest FC waterblocks from EK:

EK-FC570 GTX SE:
25th July 2011: Just finished testing and evaluating new waterblock, the EK-FC570 GTX SE (Second Edition). It is build for nVidia's latest PCB SKU (most of the time reffered to EVGA 570 HD). I'm very pleased with results, both thermal and hydraulic. EK-FC570 GTX SE has water flow over all four GPU VRM phases which have a positive effect on the cooling performance - the hottest spot of the card (measured with IR thermometer) on the backside of the PCB measured at mere ~ 54°C, PCB directly behind the mosfets ~ 45°C.

The waterblock should be available for purchase in early August (cca. 10-14 days).

EK-FC580 DCII
29th July 2011 - The most bad-ass LN2 performer - the ASUS GeForce 580 GTX DirectCU II - gets it's own full-cover waterblock for the times when the card is not running tripple digits cold : Waterblock sports brass standoffs and is compatible with both 580- as well as 570 GTX graphics card (mounts with one less screw). It is a fairly high flow (low restriction) waterblock therefore it can be used with water cooling setups using weaker water pumps!

Tgpu-max = 54°C
TH2O-max = 38.9°C

deltaT = 15.1°C

With this test setup the delta is around 15°C. The hottest part of the card measured with IR thermometer is ~ 55-56°C (PCB behind the MOSFETs).

Now... can't wait to put this baby under some 2-stage cascade tripple digit zero cold
