Waterblock Test – Joe
SUMMARY: OK choice for CPU cooling.
The EK-WW features
- Chrome-plated barb connectors for ½” ID tubing
- Lucite Top
- All copper base
The interior design is one of the more interesting ones I’ve seen:
You can see where the “WW” comes from – lots of twists and turns to enduce turbulence.
appears polished, although I could see slight ripple patterns in it.
The EK-WW was tested using the CPU Die Simulator and Waterblock Test Rig.
Pressure Drop – psi
Pressure Drop – inches H2O
Unrounded data: 0.172 C/W with 0.0011 std dev.
Test Results indicate that the EK-WW’s pressure drop (or head loss) across the waterblock is moderate.
I found that reducing flow to 0.5 gpm resulted in a performance decrease of about 1.8ºC and increasing flow to 1.5 gpm resulted in a gain of about 0.7ºC.
For a comparison of the EK-WW performance to other waterblocks tested to date, see Overclockers.com Waterblock Test Results.
The EK-WW Waterblock is an OK choice for CPU cooling, but with moderate flow resistance, the EK-WW needs a waterpump of something like 300 gph to function effectively. Other components, such as a radiator or GPU block, will add to system resistance, increasing the waterpump requirement.
