Greetings.

Looking for advice on a Hafler DH500 fan. There is a PRO Hafler 500 local, and the seller says the fan is loud.

Anyone here familiar with this amp? How easy would it be to get a quiet fan??

I dont run amps hard whatsoever , I'm also wondering if I could unplug the fan on this monster too.

Thanks for any insights.
 
The fan could just be filthy and need a cleaning and lube. Lots of very quiet fans on the market nowadays.
 
Could also be that one or both of the thermal switches are bad(shorted). Causing the fan to operate at a higher speed all the time.
 
Thanks for the comments Avionic, looking at the Amp today, I can get it for 100, so I ll go check it out. I really love the DH220 I own. I have a lot of power hungry stand mounts to feed.

I'd snag it for that price.
