Guest Posted February 14, 2019 Share Posted February 14, 2019 I bought a pair of USB powered AC Infinity 120mm fans the other day from Amazon for $44.20 delivered, they are a joined pair that can have more added, with an inline speed switch attached. They only need to be on low speed and they can’t be heard at all from normal distance. Unfortunately I can’t place both of them flat on top for the pre, but they are doing the job of keeping heat away from the HDMI board on the 8805 (known in older models to die from heat, so making sure) But yeah, all the heat back there is practically gone, so money well spent. I just plug them into the 5v usb on the back of the 8805, so at least they turn on and off with the pre. They have a 67,000 hour life and are stupidly well made. https://www.amazon.com.au/AC-Infinity-MULTIFAN-Receiver-Playstation/dp/B00JLV4BWC/ref=sr_1_2?ie=UTF8&qid=1550115946&sr=8-2&keywords=ac+infinity Link to comment Share on other sites More sharing options...
GRP Posted February 14, 2019 Share Posted February 14, 2019 (edited) I run a pair of 120mm PC fans on the rear of my cabinet (cutout was required) drawing out all the heat from the Marantz - cost nothing as plenty of them around from old PCs - used Noctua but had a few brands to choose from. Silent to the ear. Edited February 15, 2019 by GRP Link to comment Share on other sites More sharing options...
Guest Muon N' Posted February 14, 2019 Share Posted February 14, 2019 Cool! result, Simon My go to fans are Noctua, they have all sorts of fans including an industrial series, and in some series they also have 140mm and 200mm fan sizes if needing larger than the popular 120mm size. They have controllers, but not with USB connection. https://noctua.at/en/products/fan Link to comment Share on other sites More sharing options...
Dolphy Posted February 14, 2019 Share Posted February 14, 2019 @Sime V2 can the fans be run independantly? I only need one fan to keep my router cool. Link to comment Share on other sites More sharing options...

Guest Muon N' Posted February 14, 2019 Share Posted February 14, 2019 Those are nice fans as far as performance specified goes, I'll bookmark the AC Infinity site https://www.acinfinity.com/component-usb-fans/multifan-s7-quiet-usb-cooling-fan-dual-120mm/ Thanks for posting, Simon.

I was thinking they are comparable to the equivalent Noctua, but then I noticed one was stated in cubic foot per minute, and the other in cubic meters per hour. Very big difference there!

Guest rmpfyf Posted February 14, 2019 Share Posted February 14, 2019 http://www.silenx.com/index.asp These are amazing. Used them in a few builds though need to get them overseas. Link to comment Share on other sites More sharing options...
Guest Muon N' Posted February 14, 2019 Share Posted February 14, 2019 @rmpfyf Also look good, the AC's Simon grabbed seem to perform a tad better, if all these spec's are accurate. It's close though Link to comment Share on other sites More sharing options...

It's close though AC Infinity are a gold standard. TOTL no question. Silenx a bit quieter (splitting hairs) though they don't package quite as nicely. That AC Infinity kit is super nice.

Pops110 Posted February 14, 2019 Share Posted February 14, 2019 Have had one for a couple of years now, they are a really nice bit of kit. I did post a link to them in another thread that was active a while ago and the general consensus was that they are very good. cheers Dave Link to comment Share on other sites More sharing options...
