Stopping fan from causing noise

[alienmango]

Hi everyone this is my situation:

I have a cheap pro-amp I poached from ebay which puts out 600w rms, I use it to power a subwoofer in my bedroom (normally) and I only use a few watts (under 100) 99% of the time for normal listening.

Would it be safe to obstruct the fan with a stick to stop it making noise when it's only on low or could it damage the amp in some way? the fan noise is obtrusive at low levels.

Thanks.

Do you think that sounds like a good idea?

Is he serious??? Swap the fan. Disconnect from mains first. Keep all components away from water. Wear industrial globes and thick rubber boots, fireproof jacket and welding mask

Well basically no BUT .... if it's only outputting 10 watts it's hardly likely to output much heat is it. :cheers:

I understand is your reaction is this.... :wall:

Stopping the fan with a pencil will cause more heat than yr amp. Smoke too most likely

Perhaps you might consider why they bothered fitting it with a fan in the first instance.

Heat does not necessarily depend on the volume control position.
Wattage doesn't matter either. I know some 10 watt Class A ampsthat make a very nice room heater.

don't do anything with the fan. If it's too noisey, try getting a replacement silent fan from cpc or Rs/farnell type place.

Why not have the noisy fan replaced with one of these quiet fans , it should not cost much and it won't burn your house down

Well it's designed to be run at full volume (and even slightly into clipping) for hours on end with no problems...hence the fan. How likely is it really that a 600wrms amp is class A (given that it's also a pro amp) ???

Will fit a new fan, thanks for the recommendation.

try placing the amp on two squash balls cut in half.

the sound of the amps fan maybe made lowder by were you have the amp seated - glass surface, cupboard etc. the rubber of the squash balls will dampen/absorb any excess vibration/noise output by the fan.

oh and no... the spot makes no difference.
