"Viscool CPU V2 Waterblock"
SUMMARY: Very good choice for CPU cooling with moderate-high power waterpumps.
The good guys at Viscool were nice enough to send their CPU V2 Waterblock waterblock to test.
The Viscool CPU V2 features
You will notice below that the Viscool CPU V2's pressure drop is fairly high - this is due to its interior design.
The base is well finished; I used the Poor Man's Flatness Test on it with good results:
Rotating the base 90º:
This view is more difficult to see as the polishing marks are circular.
Mounting involves fixing four brackets to the top of the waterblock:
You can orient the brackets to fit just about any configuration. Included with the waterblock is the mounting hardware:
The Viscool CPU V2 was tested using the CPU Die Simulator and Waterblock Test Rig.
Test Results indicate that the Viscool CPU V2's pressure drop (or head loss) across the waterblock is moderately high; flow resistance such as this means that Viscool CPU V2 will require a good waterpump - anything less than 300 gph might compromise results, depending upon how restrictive other components are in system.
I found that reducing flow to 0.5 gpm resulted in a performance decrease of about 0.7ºC and increasing flow to 1.3 gpm resulted in a gain of about 0.4ºC.
For a comparison of the Viscool CPU V2's performance to other waterblocks tested to date, see Overclockers.com Waterblock Test Results.
Viscool's CPU V2 Waterblock is a very good choice for CPU cooling; the Viscool CPU V2 should perform well with moderate-high power waterpumps (300 gph or more), as long as other components do not unduly restrict waterflow.
Thanks again to Viscool for sending this our way.
