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.

rev 4

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 TEST

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

WATERBLOCK TEST RESULTS

Test Conditions: Inlet Water Temp: 28.5 C; Mounting force: 15 pounds; Heat Load: 70 Watts.

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.

CONCLUSIONS

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.
