These FANs are LOUD! so i changed for a these antec, the only ones i could find in my local BestBuy. The label say 2000RPM, not the best out there but the noise is down to 25dba. (compared to 60dba on the stock FANs.)

The noise has gone down but the temps are going up 60-70, vs 40-50 with the stock fans.

Anyone has any recommendation on not too slow but not too noisy FAN??

I understand that the lower the better but does anyone know the acceptable temp range of the Coincraft A1?

Update: As per amt_miner suggestion going with the BGears - B-blaster. Reviews coming in 2 days.
