Thats the problem, the ratio, intake/outtake is not equal.
The sound is ok to deal with, I will be getting a fan controller soon along with another TORNADO. Its actually 55.2dba on newegg.
Ill try with the TORNADO, on the side panel tomorrow, along with the exhaust. That way it blows 84.1cfm onto the cpu, gpu and mobo, although I dont have the gpu yet, nor ram.
Only thing I am scared about is how the plexiglass will hold up to the TORNADO, it will probaly vibrate more than I want.
Have you seen the 92mm version?
