Swiftech was kind enough to send us two coolers that look completely different from anything that we've ever tried before. Normally, a cooler is made from a huge chunk of metal, usually copper these days. All the CPU coolers have fans on top but this one actually has a fan as optional extra.
The products we've looked at are the MCX462-V for AMD chips, while Swiftech's Pentium 4 version is the MCX478-V.
It's very easy to mount this cooler and it will only take you few seconds to do it.

When I tried this cooler with an Athlon 3000+ overclocked to 3200+ it performed very nicely. We overclocked the bus from 333MHz to 400MHz and raised its frequency to 2210 MHz. we only used a 12-inch cooler with a very slow rotation rate, much less then 2000 RMP. This made our machine almost soundless, with the temperature around 50In this scenario we are talking about almost soundless machine as level of noise is extremely small. The temperature was a constant 50° Celsius. If you speed up this cooler, you will still get a very quiet machine and will cool your CPU to acceptable rate even less then 40° Celsius.
I can confirm very good cooling results for the Pentium 4 version of this cooler. It performs well, it's quiet and it cools 3000+@2210 MHz-3200+ with no crazy crashing.
This cooler is state of the art and costs around 50. µ
