Chipset Waterblock Test – Joe
SUMMARY: Good choice for chipset cooling.
Swiftech MCW20-R features
- Push fittings for 1/2″ OD tubing
- Mounting hardware
The interior is devoid of pin fins, swirls, gates or channels – this is a very basic design optimized for low pressure drop – a critical factor when waterblocks are daisy-chained.
The base is typical Swiftech:
Very flat – do not try lapping this as you will only make it worse.
Overall, very good build quality.
The Swiftech MCW20-R was tested using the CPU Die Simulator and Waterblock Test Rig.
Pressure Drop – psi
Pressure Drop – inches H2O
Unrounded data: 0.224 C/W with 0.0008 std dev.
Test Results indicate that the Swiftech MCW20-R’s pressure drop (or head loss) across the waterblock is very low; resistance such as this means that Swiftech MCW20-R will perform nicely with moderate power waterpumps, especially if other components in the system are not overly restrictive.
I found that performance degraded by about 2.4ºC at a flow rate of 0.5 gpm and improved by about 4.1ºC at 1.5 gpm – the widest results of any waterblocks tested to date.
For a comparison of the Swiftech MCW20-R’s performance to other waterblocks tested to date, see Overclockers.com Waterblock Test Results.
Swiftech’s MCW20-R Waterblock is a good choice for chipset cooling, particularly for its low pressure drop. As chipset waterblocks are usually fitted in series with a CPU waterblock, low flow resistance is particularly important for a chipset waterblock. Note that this waterblock is 1.5″ high, so plan accordingly.
