Alphacool NexXxos NVXP-3 GPU Waterblock

Test setup

Test Setup

As I am using a 1/2" ID setup on my watercooling I attached the 1/4" BSP to 1/2" Barbs to the block.

The test rig used is:

Hardware:

Intel Conroe E6600 @ 3379MHz
Asus P5W DH Deluxe
Club3D 7900GTX 512mb

Watercooling:

Aquacomputer Evo 360 Radiator
Danger Den 3.5" Bay Res
Laing D5 Pump
Swiftech Apogee CPU Block
Clearflex 1/2" ID Tubing
Jubilee Clips to seal it

I added some Green UV Water Dye and the appropriate amount of Zerex Watercoolant.

The loop was left to leak-test for 12 hours prior to testing.

Testing

Idle Tests were performed by leaving on the PC on for 30 minutes and then recoding the temperature using the nVidia monitoring software, getting the average result over a 30 minute period.

Load Tests were gained by first running a loop of 3DMark06, then running RTHDRIBL. The temperatures were recorded over a 30 minute period, and the average result obtained.

All of the tests were performed at an ambient temperature of 25°C.

Overclocking was done using nVidia's forceware drivers and using the coolbits registry hack.

Great review mate, I sadly can think of many improvments they could make to the design.

Mr. Smith
Sound methodology and a balanced conclusion.

I'd take the EK over the alpha due to ability to change barb direction... That and it performs better lol

Thanks guys for the feedback, it's very much appreciated as it allows me to refine the process. Is there anything else that you would like to see done in future reviews that I haven't included?
