one fan or two

post #1 of 3
Thread Starter 
Recently purchased a thermaltake water3.0 performance closed loop cooler. The fans were loud as I expected so I decided to change them out for some Gentle typhoon Ap-29. After a little soldering I got them working as PWM fans. They are rated at 36 DBA each. My question is if I were to get one Delta SHE fan rated at 53 DBA would be quieter then the 2 typhoons.

No, the Delta would definitely be the louder over the pair of AP-29's. In general, when you double a sound source you get an increase of 3 dB. So with a single AP-29 rated at 36 dBA, two would be 39 dBA, four would be 42 dBA, etc... Hope this helps. smile.gif
