I'm not sure which specific model Power supply I have, but its a 350w antec which came in my Antec Sx1035 case. I was poking around in the case yesterday, and realized that after putting silencers in the 4 fan slots, and a panaflo m1a on the processor, the main source of noise left in there are the 2 power supply fans. Can these be replaced with something quieter, that wouldn't reduce airflow?
