Waterblock Test – Joe
SUMMARY: Very good choice for CPU cooling with moderate power waterpumps.
The Cyclone EvolutionS features
- ½” integrated hose fittings with only one seal between the top & base
- Directional velocity inlet
- High density / extreme surface area channelled base
- Type II, Class 2 Anodization for corrosion resistance
You will notice below that the Cyclone’s pressure drop is moderate – this is due to its interior design:
The Cyclone EvolutionS series is composed of three waterblocks; the Cyclone Evolution, which has the least fins and least restriction, the Cyclone EvolutionS V2.0 which has a higher fin density and the Cyclone EvolutionS V2.5, which has the highest fin density.
In addition, the top features a slot
which directs the water over the base’s channels.
No such thing as a free lunch – increasing turbulence and chanelling waterflow will require some “effort”, and it shows up in pressure drop readings (not good or bad – just something to recognize).
I did not test the Cyclone’s mounting clamps, but would caution that ensuring mounting pressure such that the waterblock is flat to the CPU core is critical to realizing performance. A mounting system using screw tightening might be a tad more difficult, as it depends on equality between the sides.
appears well finished, although performance could be enhanced a bit by well done hand lapping.
The Silverprop Cyclone Evolutions was tested using the CPU Die Simulator and Waterblock Test Rig.

Unrounded data: 0.143 C/W with 0.0013 std dev.
Test Results indicate that the Cyclone Evolutions’s pressure drop (or head loss) across the waterblock is moderate; flow resistance such as this means that Silverprop’s Cyclone Evolutions should function OK without using a very large waterpump, although anything less than 300 gph might compromise results, depending upon how restrictive other components are in system.
For a comparison of the Cyclone’s performance to other waterblocks tested to date, see Overclockers.com Waterblock Test Results.
Silverprop’s Cyclone Evolutions Waterblock is a good choice for CPU cooling. Flow resistance is a tad on the high side, although the Cyclone Evolutions will perform very well with moderate power waterpumps (300 gph), as long as other components do not unduly restrict waterflow.
Thanks again to Silverprop for sending this our way.
