InnovaCOOL Rev4

Waterblock Test – Joe

SUMMARY: Good choice for CPU cooling, but requires a high power waterpump to hit 1 gpm water flow – optimized for ¼” fittings.

The good guys at High Speed PC were nice enough to send a InnovaCOOL Rev4 to test (Go HERE for Innovatek’s website – in German).

The InnovaCOOL Rev4 features

• 8mm/¼” (OD) compression fittings
• Weight 275g
• Size 65 x 50 x 53 mm
• Solid copper core
• Plastic outer hull – four colors available with space for two LEDs
• P4 and Socket A mounts available

The base shows no signs of polishing marks:

The mounting system is quite good in design – it should be secure and very easy to use.

The InnovaCOOL Rev4 was tested using the CPU Die Simulator and Waterblock Test Rig.

Test Results indicate that the InnovaCOOL Rev4’s pressure drop (or head loss) across the waterblock is moderate; flow resistance such as this is not surprising given its ¼” fittings. This means that Innovatek’s Rev 4 requires a moderately large waterpump to hit a 1 gpm flowrate, although it is designed for lower flow systems.

However, I ran a test at 0.5 gpm and found the impact to be about 0.7ºC, not terrible by any means; pumping 1.5 gpm through it increased performance by about 0.7ºC.

For a comparison of the InnovaCOOL Rev4’s performance to other waterblocks tested to date, see Overclockers.com Waterblock Test Results.

The InnovaCOOL Rev4 waterblock is a good choice for CPU cooling, although extracting performance will take a very good waterpump. However, if other components unduly restrict waterflow, flow through the system could be considerably less than 1 gpm.

For users with systems using ¼” tubing and fittings, The InnovaCOOL Rev4 waterblock is a good choice.

Thanks again to High Speed PC for sending this our way.
