Waterblock Test – Joe
SUMMARY: Very good choice for CPU cooling with moderate power waterpumps.
The MCW5000-A features
- ½” OD push type hose fittings
- ½” Thick pin fin copper base
- Anodized aluminum top
You will notice below that the MCW5000-A’s pressure drop is fairly low – this is due to its interior design:
The pins are not overly dense and there is some space above the pins for waterflow – overall, an efficient design.
The base is typical Swiftech:
very well finished – performance will NOT be enhanced by hand lapping.
The MCW5000-A was tested using the CPU Die Simulator and Waterblock Test Rig.
Pressure Drop – psi
Pressure Drop – inches H2O
Unrounded data: 0.152 C/W with 0.0012 std dev.
Test Results indicate that the MCW5000-A’s pressure drop (or head loss) across the waterblock is relatively low; flow resistance such as this means that Silverprop’s MCW5000-A should function very well without using a large waterpump, although 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 0.6ºC and increasing flow to 1.5 gpm resulted in a gain of about 0.2ºC.
For a comparison of the MCW500-A’s performance to other waterblocks tested to date, see Overclockers.com Waterblock Test Results.
Swiftech’s MCW5000-A Waterblock is a very good choice for CPU cooling. Flow resistance is fairly low; the MCW5000-A will perform very well with moderate power waterpumps (300 gph), as long as other components do not unduly restrict waterflow.
