Has anyone here on the site used Aircom S9 cooling fans to keep there equipment cool. Or if anyone has any suggestions I would appreciate them. I have to keep my equipment in a cabinet which is listed. I have an 8" clearance between equipment and openings from front and back of the cabinet but notice my equipment isn't getting hot but is warm to the touch.
Thanks Gary

If it's not shutting down due to heat then you are fine and do not need fans.

Maybe, but IMO there is a very close correlation between the minimal space many HT types put between their equipment and all the capacitor problems reported.

AC Infinity makes some very nice cooling equipment. I have an Aircom T8, they are ultra quiet and very well made and work very well. Here is a link to AC Infinity for anyone not familiar with them www.acinfinity.comThis is the Aircom T10 which has rear exhaust and digital controls. They make a lot of different versions of this, top exhaust, rear exhaust, front exhaust, with digital controls or without, etc. and many other cooling components as well. Very nice quality stuff.  |

8” seems like plenty of space, I’d avoid fans if you can.

Maybe I am over thinking about heat damage to stereo components. Seems like not many people on the forum aren't using cooling fans. Maybe because of the fact their using racks instead of cabinets. Thanks for those of you who expressed their opinion.

looking for a 'one box' solution or are you willing to do some work? As in DIY? Quietest fans available MIGHT just be the NOCTUA line. noctua.at/en/products/fan/nf-a12x25-flx/specificationAbove linked fan is a 120mm unit and draws 140ma, which I think is within range of the remote trigger power. other solutitions exist for power, using wall-wart and a relay to trigger ON from the remote trigger output of the amp. |

Oh this thread is amazingly well timed. I *just* (today) bought and installed an Aircom T9 from Amazon to fit on top of an XPA-1 gen2 amp which has the *very* occasional heatsink click (once every 15-20 minutes or so) that was driving me nuts. Id already replaced all external screws with rubber washers and losened them as per tech support advice, which made things better but hadn't cured it completely. Put some black rubber seal (from home depot) underneath it to make a good seal and draw the air through.
Haven't heard a heatsink click yet (but it's only been 30 minutes so far). Not sure if I hate the fan noise more than the click yet although it's very quiet.

I'll reiterate my comment that unless your gear is overheating you do not need fans. Indeed, many pieces of equipment, especially amplifiers, are designed to operate in a specific temperature band and to passively dissipate the heat through their design. Adding external cooling, especially is if forces air through the component, can degrade performance. All well-designed components will protect themselves from over-temperature and only then do you have an installation issue to address.
"Lowered life expectancy" is possible, yes, but is generally the difference between 20 years and 20.5 years.

I'm not disagreeing. It shouldn't need a fan, true. However, I'm trading a very intermittent (but highly annoying) heatsink "ping" noise for a constant low-level white noise. So far I'm happy with the trade-off but time will tell.

With, I hope, the air sucking UP thru the amp and exhausting UP, where does the air go next?
Into an enclosure?
I leave the doors open on my cabinet. If I close 'em, the part with the satellite receiver gets warm.
If I run the PS3 (in another section) that'll really COOK unless open.
My amps are in the open, on raised stands and NEVER get too hot, even cranking into my very low sensitivity panels.
DY is both right and wrong.
Stuff is designed to run warm. Heatsinks are 'calibrated' to expected heat load so output devices won't overheat. Though SOME amps can take 1/3 power forever others under those awful conditions will COOK and shut down.
If you look, your BIG Power Supply caps will be either 85c rate or 105c rated.
But still and all, TOO hot, but not hot enough to trigger a shutdown IS generally considered bad for lifetime. And some parts of the amp might NOT get the airflow you desire for 'extra' cooling. That might be a problem, if amp is in an enclosure
amd run vigorously.

The XPA-1 is in the open, not in a cabinet. It doesn't get too hot, but just hot enough to make the heatsink "ping" a few times after 30 - 45 minutes. It's the randomness of it that is driving me nuts. I'm in a listening session and after 30+ minutes I'm tense just waiting for the small "ping". It's probably psychological more than anything else, but putting the fans on top has kept it cool enough (at the cost of some constant white noise, which is easy to ignore) that the heatsink doesn't ping.

To ease 'noise', any way to turn the fans down some? Can you measure any of the temps?
Slower fans will raise temp SOME but still provide cooling.
Fans might come in handy when summer hits. My house warms in late afternoon and my amps and other electronics 'know'.

It's due to the screw holding down the transformer. As the transformer heats up/cools, it clicks or pings. Call Emotiva, for instructions. It's a very easy fix. The idea is you loosen the screw that's on the bottom of the amp a tiny bit and it goes away. You don't have to send it in. |

If you open up the amp, PLEASE be careful as there’s enough juice inside that box to ruin your life. 🔥 |

With 8" between gear and opening front and rear, you really should not need cooling.

I already worked with Emotiva tech support (who are top-notch) and they got me to loosen the six screws holdingothe heat sinks to the case from the outside. That got rid of most of the noise. There's only the remaining intermittent ping, which sounds to me more like a heatsink sound than a transformer one. |
