djb Posted July 28, 2018 Share Posted July 28, 2018 Am trialing an AV amp for 2 channel purposes Lwxicon L X 7 Its a beast weighs close to 32 kg 7discrete amps has slightly better mids and highs than my current set up. BUT like some AV amps it has a temperature controlled fan. I’ve always been opposed to fans in hifi amps they provide a whole new element/layer of noise floor. This is less obvious a problem with dynamic music played loudly. Sadly for me 90% of my listening (vinyl and Cd) is classical chamber music and jazz blues.. so if I am to buy it I have to lessen this noise.. i have access to some rubberised acoustic fabric that I currently use on 4 frames 180 cm high X 40 cm wide as great bass traps. so it seem I could : 1 build another similar horizontal frame to place immediately behind the amp which is on the floor below my rack. 2 cover the top of the amp with a "wrap" of the acoustic fabric - Seems likely to activate the temp controlled fan more often?! 3 bundle/loosely knot the acoustic fabric in an open weave bag and place over the rear third of the (out of sight) amp. 4 combinations of 1 2 and 3. 5 other Suggestions please no @evil c only listening to Pink Floyd is not a solution Link to comment Share on other sites More sharing options...
elcamry Posted July 28, 2018 Share Posted July 28, 2018 There are some very quiet computer fans available of various sizes that may be suitable . 3 Link to comment Share on other sites More sharing options...

Failing that - install a noisier AC to distract as it were ! Or embrace big band slash heavy orchestral. 3 1 Link to comment Share on other sites More sharing options...
kroozzy Posted July 28, 2018 Share Posted July 28, 2018 see if you can retro fit a water cooled system that is built for PC's. there are heaps of different options, there are Water Cooling Units for; CPU, graphics card, RAM and onboard chips. forget the myth they are crap and leak, that was many years ago, they have got it all sussed out now. i use them in a overly specced PC for graphics and live in a lot more quiet .. though as @elcamry mentioned, there are many very very quiet fans that are available, just go to get size/s required and go into a decent pc store and they will be able to help you out. the pc i am on at moment has four fans and there is no way i can here it over the tv on low volume.

AC is a great suggestion, as when turned on will reduced the fan in the amp from turning on hard.... Alternate solution would be to use said amp to drive a horn setup so its easier to drive than those ridiculous power hungry panels....2 advantages here. Use a set of headphones instead Place amp outside in the front yard and wired it back into the listening room to power hungry panels... Have a GTG everyday and position everyone around the amp to block off fan noise from amp. Go class D.... highly efficient and no fan in use! 1 Link to comment Share on other sites More sharing options...

How interesting, David. So is bass not as good as your Amber amps ... or the same? BTW, yes - 7 discrete amps ... but they share the one PSU, I suspect. 59 minutes ago, djb said: BUT like some AV amps it has a temperature controlled fan.

Chris's (Kroozzy's) suggestion seems very apt - but is going to: a. be difficult to fit, and b. will not be inexpensive. Andy Link to comment Share on other sites More sharing options...

ThirdDrawerDown Posted July 28, 2018 Share Posted July 28, 2018 Put the amp in the next room, or a loft and use long cables. No doubt you have a loft? Otherwise the silent PC fan coupled with an enclosure seems best. Let me know if you need plasterboard and green glue so you can have airspace in your solution. We await answers about the Ambers, for they are very nice amps (you've said). Link to comment Share on other sites More sharing options...

Guest Point source Posted July 28, 2018 Share Posted July 28, 2018 (edited) Ok the fan is ‘kicking in’ under load. Remove the top case and see whether the fan still kicks in. if so purchase a very expensive BUT quiet Dyson fan to alleviate the issue. I should add that in summer I use a mistral fan to move the air around my valve amp ..12 valves in the power stage. It does make a noise but not that bad, in the case of @DJB it would probably be like squeaking chalk on a blackboard..

gonefishing999 Posted July 29, 2018 Share Posted July 29, 2018 @andyr I forgot all about fans as CX-5 don't fans and Ozzie is dreaming about having one so he didn't know about the fans. I like the idea of Dyson fan an a Daikin AC very Quite. Could be install when Leo the sparky come over. Link to comment Share on other sites More sharing options...
gonefishing999 Posted July 29, 2018 Share Posted July 29, 2018 @djb Have a better suggestion for the amp I can cut a hole in the floor with my chainsaw and sink it below the floorboards very cost effective. Noise gone. Link to comment Share on other sites More sharing options...

kroozzy Posted July 29, 2018 Share Posted July 29, 2018 are those dysons seriously quite ?? something to consider placing behind Krells and tubes in summer ?? most of the time fans are noisy due the to ducting or vents the air needs to flow through, take the fan out of the passage of flow and it is whisper quiet. so comes the question of passage of flow, or the entry and exit vent or slotted grove designs. better to have a non slotted entry and exit with a custom fine filter to remove dust and the flow of air will not create a whooing sound as it flows through Link to comment Share on other sites More sharing options...
gonefishing999 Posted July 29, 2018 Share Posted July 29, 2018 @kroozzy Fans are monitored constantly so no removal or it will shut down. Link to comment Share on other sites More sharing options...
