Dr Morbius Posted May 16, 2012 Share Posted May 16, 2012 Hi, Does anyone know of a brand or type of (as quiet as possible) cooling fan that I could put on top of the vent of my H.H.Scott 299C amp? I'm thinking a 3 to 4 inch size that plugs into the back of the amp, so when I turn the amp on, the fan turns on with it. Thanks, Steve Quote Link to comment Share on other sites More sharing options...
Guest " " Posted May 16, 2012 Share Posted May 16, 2012 bought mine at radio shack. I used a 2uf film capacitor in series with it to slow it down so it can't be heard. Quote Link to comment Share on other sites More sharing options...

JBL4645 Posted May 16, 2012 Share Posted May 16, 2012 Many fans on this list that run as low as 6.5dbA. I'm also looking for cooling fans for my cinema equipment as they sound like leaf blowers. http://www.quietpc.com/products/casefans Quote Link to comment Share on other sites More sharing options...
JBL4645 Posted May 16, 2012 Share Posted May 16, 2012 I like the idea of rack mounting cooling fan systems. I'm looking around for thee lowest of low prices. I guess if on tight budget can always get parts cheaply and make one to sound very soft silent running. Quote Link to comment Share on other sites More sharing options...
jhoak Posted May 16, 2012 Share Posted May 16, 2012 I tend to salvage fans out of computer hardware. Many are pretty loud when running at their rated 12V but whisper quiet running at 9V. I have a BUNCH of fans here and a few 9V "wall warts". I can hook you up with one if you want to try it. Sitting on top of my Onkyo receiver is a 4.5" fan that runs 24X7. I can't hear it with my ear right next to it. It is one of the few thermally controlled fans that I own. When there's no heat it's moving really slowly. It has to have 12V to make the thermistor work correctly. Even af full RPM it's very quiet. I've tried a couple of 110V fans in the 4.5" to 6" size and I'm pretty sure that there are jet engines that are quieter. Quote Link to comment Share on other sites More sharing options...

Marvel Posted May 17, 2012 Share Posted May 17, 2012 I've got some 6-8 inch fans out of some older Dell servers. Drop the voltage a little bit and they run very quiet. Bruce Quote Link to comment Share on other sites More sharing options...
Guest davidness Posted May 17, 2012 Share Posted May 17, 2012 I had my tube amp on a rackmount shelf. Above the amp, I installed a Middle Atlantic Ultra Quiet rackmount fan unit, that automatically adjusts the fan speed depending upon temperature build-up. It includes a temperature probe. See here. I acutally just stopped using mine, so if you're interested, let me know and we'll discuss price. I have the model UQFP-4. Quote Link to comment Share on other sites More sharing options...
