Quieter 305 Fan?

I noticed that my fan hums pretty loud and it kinda draws my attention from the sound of the engine (it really is that loud). Kinda bothersome for me. I was wondering if anyone had any ideas for a quieter fan that still worked in keeping the car cooled off.

Re: Quieter 305 Fan?

if you have the original clutch fan,probably has a seized up fan clutch-driving the fan at WP pulley speed all the time,creating lots of noise and HP draw at higher rpm...If that is the case,you will free up quite a bit of HP once the bad fan clutch is replaced
