Waterblock Test – Joe
SUMMARY: Very good choice for CPU cooling, especially with low power waterpumps.
Brian over at BeCooling was nice enough to send a Slit Edge waterblock to test. I used this waterblock extensively in developing the waterblock test rig, so I’m very familiar with its performance.
BeCooling’s Slit Edge features
- Chrome-plated barb connectors for ½” ID tubing
- Anodized aluminum top with AMD and P4 mounting holes built in
- 4 tapped corner holes which can be used to retain a peltier and coldplate
The “Slit Edge” refers to 11 small slits, each 1/16″ wide and to a depth of 1/4″, machined into the copper baseplate. These are designed to increase turbulence over the CPU core area, thereby increasing cooling performance. In addition, the large ½” barbs and relatively clean interior are designed to minimize pressure drop.
The BeCooling Slit Edge was tested using the CPU Die Simulator and Waterblock Test Rig.
| Waterblock | C/W | Freeflow GPM | Waterblock GPM | Waterblock PSID |
| BeCooling Slit Edge | 0.18 | 1.00 | 0.96 | 0.15 |
Unrounded data: 0.178 C/W with 0.001 std dev.
Test Results indicate that the Slit Edge’s pressure drop (or head loss) across the waterblock is minimal; low flow resistance such as this means that BeCooling’s Slit Edge should function well without using a large waterpump.
For a comparison of the Slit Edge’s performance to other waterblocks tested to date, see Overclockers.com Waterblock Test Results.
BeCooling’s Slit Edge Waterblock is a fine choice for CPU cooling. In addition, with minimal flow resistance, the Slit Edge will perform very well with moderate power waterpumps, as long as other components do not unduly restrict waterflow.
Thanks again to BeCooling for sending this our way.
