Results SP-94 vs MCX478-V:
First up we have the P4 running at default speeds:
Both heatsink are able to keep the CPU under 20°C over the room temperature, the SP-94 takes the lead at the lowest CFM, with a difference up to ~5°C. When the Vantec Tornado is used both heatsink perform extremely well, keeping the CPU under 30°C!
Now let's speed up the P4 to 3.2Ghz, the output is now 90Watt of heat!
The difference between the 2 heatsinks remains constant, and both turn in impressive results. The dead spot on the 90mm Papst fan is bigger then the 80mm explaining why it trails behind a small margin.
These heatsinks are at the top end of the P4 air-cooling solutions, the SP-94 has a small lead on to Swiftech, but both products will provide you with a lot of headroom for overclocking your Pentium 4 setup. And even when using a very silent FAN they will keep the CPU near the 40°C mark.
Zalman has been proven as a solid solution if you like silence, how does the Swiftech perform when we put it up against it? Lets find out ->
