Used to replace fan in Thermalright 120 Extreme. Overclocked a Core 2 Quad to 3.6 with a 1800fsb, with this fan the tempratures droped 8-9C from stock. Yes, It can get loud, when keeping you CPU cool is very critical, like linpack stress test. Other than that it''s quiet when gaming and other tasks that may stress the cpu a little.

...if your mobo is a modern one that fully supports the 4pin CPU fan control stuff. (My asus Rampage formula does). On my system, when the system is idle, the fan spins at 734RPM and is dead silent. When I put a big load on the CPU (like video encoding), the fan will spool up to about 1300 RPM. Then you definitely can hear it. Under super heavy load, I got the fan to spin up to 2000RPM at which point it is definitely loud. But, it''s doing is job, ie varying the RPM automatically depending on CPU temp. Great fan.

This fan is amazing! It moves alot of air and is quiet, I can''t hear it outside of the case. This fan was used to replace the Tuniq 120 stock fan and has aided in bringing down my idle/load temps by about 6-10C. Definitely recommend it since it is one of the only PWM fans with a respectable (100+CFM) airflow (for the ones looking for the best in air cooling). One minor nitpick is that the motor could have probably been made smaller like the Scythe Slipstreams and allow the same airflow with lower RPM speeds and noise (got 3 1900rpm slipstream fans :D).
