4 fans are needed. 2 rad fans, 2 exhaust/intake, I might just get rid of the H20 and go with the Corsair h50. Seems like a better idea.
This cooling system doesn't have my chip any cooler (running at 54C watching a BR or recording HD).
Either would be fine if they will be placed vertically. If they will be horizontal, use the Scythe because they have fluid bearings. Most likely the radiator pump will be much noisier than either.

A very unusual fan from an Austrian company posing as a research institute. Unusual blade design produces more airflow than usual, but possibly at the cost of reduced pressure. Reports from real users have suggested that, despite measuring higher, actual cooling power is slightly less than it should be. Noise character was very broadband and became inaudible at a relatively high voltage. However, it lacks the buttery smoothness of some other fans. An effective choice for a case fan, but the questions raised about its pressure make us hesitate to recommend it for use on a heatsink. Added Mar/07

A longtime favorite. Was and remains SPCR's de facto reference 120mm fan, though it provides slightly less airflow-for-noise than the Noctua. Its noise character is smooth and low frequency, generating a low hum when it is audible. Its bright orange color has put off some people, and it is now available in an elegant black-and-white edition. Closed corner flanges can sometimes cause problems with mounting clips, but this is easily fixed with a dremel or hacksaw. Sample variance is a bit of a question mark, and at least two revision of this fan have been identified in the wild from two different manufacturers. Luckily, the change in manufacturer did not seem to affect the noise signature. Added Mar/07

Sounds and performs almost identically to the Nexus, though its noise character is very slightly more tonal. However, quality control with the S-Flex appears to be better, and the Sony-FDB bearing is thought to be quite high quality. Some people have commented that the lowest speed model has a trace of ticking that is absent in higher speed models. Our own testing confirms this. Added Mar/07

Basically identical to the Scythe S-Flex series, with minor differences in frame design, default speed, and possibly vibration level. Its rated speed of 1,000 RPM makes it a slightly better choice, though; it's acceptably quiet at full speed but tolerates undervolting a bit better than the low speed S-Flex. Availability is currently limited to Japan only. Added Mar/07
