While the Scythe Samurai Z is not a highest-performance overclocker's cooler, I must say I still love it. The installation is very easy, does not require any tools and can be completed in a few seconds. With support for Socket 478, 775, 754, 939 and 940 the compatibility could be called universal. I also like that mounting kits for all these platforms are included, other manufacturers will make you pay extra for that.
On the cooling performance side the Samurai Z is a bit weak. However, while the temperatures might be higher, our test system was stable at all times. In return for higher temperature you get a very quiet fan.
I recently moved my medium overclocked, watercooled Socket 478 system into a new case and was worried how I could install all the watercooling stuff there without major surgery. Right in the nick of time I got this heatsink and decided to completely get rid of watercooling. I'm using the Samurai Z on my P4 2.4C @ 3.1 and the system is quieter than before.
