AC Infinity Aircom S9 Quiet Cooling Fan System 17in Top-Exhaust for Receivers, Amps, DVR, AV Cabinet

My Denon AVC-X4700H runs hot, almost disturbingly hot. My 4 ohm speakers only deliver 87db per watt so are a tough drive, and whilst my front speakers are driven by another amp, the AV amp still drives another 4 speakers and the subwoofer. The S9 has proved to be fantastic at reducing the running temperatures significantly and the auto temperature control function means you can leave it to its own devices which is a real plus. It turns on/off as required so no hassle there. It generally runs on setting one which is only just audible, but ramps up to setting 2 out of 3 under load. Overall I'm very pleased with it, its built well, looks good, and is well priced for what it offers. If you own a Denon/Marantz AV amp then these things are a great addition and the temperature reduction will likely significantly increase the product life from excessive heat wear & tear.

I purchased an Aircom S9 to keep a recently repaired, near 30 year old JVC RX-905V cool after spending $150 to rebuild the power supply board after the low voltage capacitors on it blew and caused it to fail. Some people may (rightfully) question why anyone would spend that much to repair a 30 year old receiver instead of putting that money towards a new receiver. All I can say is, my JVC RX-905V is spotless, without imperfection and has served my now old ears very well for many years. Paired up with four Boston Acoustics CR-9's and an M&K 500w Subwoofer, it puts out music that my ears absolutely love and have been unable to find in any of the new, high-end units I tried. To even try and replace the features, functionality and sound it has with something else would mean spending well over $1,000. So replacing my receiver wasn't an option. So one day after getting my receiver back from the shop and feeling how hot it was getting, I happened to type "stereo cooler" in the search box here on Amazon Shopping. What?! There's such a thing?? Show me! And up popped the Aircom series of coolers with a lot of five star ratings. I read well over one hundred of them and placed my order. When my Aircom S9 arrived I quickly unpacked it, set it on top of my stereo, followed the easy peasey setup guide and turned my stereo on. I tried the automatic settings on the S9 letting the thermal settings cool my beloved JVC RX-905V and manually setting the fans to 3/4 speed to keep it cool. Both worked equally well and I ended up letting the thermal sensing control the cooling for my receiver. Now, I did have a small issue with the initial unit that I received from Amazon. The power supply ("wall wart" in amateur radio speak) generated a TON of RF noise which made receiving FM or AM radio signals on my receiver impossible. I contacted both Amazon and Aircom about the issue. Amazon's response was to ship a new unit right away. Not exactly what I wanted because I considered it a waste to ship an entire new unit when a replacement power supply would suffice. Aircom responded to my email inquiry within two hours and was profusely apologetic about the issue. They offered to send a new power supply (which is what I wanted) right away, all that I needed to supply to them was my Amazon order#. Amazon had already shipped a new unit so I opted to wait before proceeding with Aircom and informed them of such. I received a new Aircom S9 from Amazon and installed it quickly. I discovered the replacement has the exact same issue as the original and as I emailed the nice folks at Aircom about, their 1250mw power supply for their device puts out far too much heat in too small of a space and creates a lot of RF interference wiping out AM and FM reception due to lack of proper shielding. Since I'm an amateur radio guy, I rummaged through my parts bins and found a Fair-Rite Type 43 Toroid Choke and wrapped the power supply cable for the Aircom S9 around it 11 times. Problem solved, no more interference from the Aircom supplied Power Supply and now I'm a very happy camper. I genuinely like and appreciate the engineering that went into the Aircom S9 cooling device itself. It does the job well for my legacy receiver and I've no doubt it will help extend the life of it. Aesthetically, this is a very nice stereo cooler. It's quiet (even on high speed), looks great and does a great job keeping my receiver cool. I've been known to "exercise" my amp's capabilities and living in a townhome that means my neighbors occasionally hear me. LOL! My only "nit" is with the power supply that shops with it. It's poorly designed, generates too much heat and generates a ton of RF Interference. This is an easily fixable problem that I outlined in my email to Aircom hoping they pass it off to their engineers. If you're considering an Aircom S9 for your receiver/amplifier, this unit delivers the cool. Just do yourself a favor and order a Fair-Rite Type 43 Toroid along with it (those are easily found here on Amazon for about $8) and wrap the power cord around it 10-11 times to eliminate the interference. Then sit back and let the Aircom S9 keep your stereo receiver/amplifier nice and cool. Note: I purchased my Aircom S9 for my own personal use. I've not been asked to provide my review above by Aircom nor have I been compensated in any way for my review. I read so many good reviews about this unit that I felt I had to add my own and point out the flaws with the power supply that ship with it. I'm hopeful that Aircom incorporates the feedback I left them in email about the power supply and take steps to fix it. Their S9 device is a beautiful stereo cooler, it does a great job and it deserves a decent power supply.

El producto lo adquirí porque tengo un amplificador de audio que por diseño se calienta bastante aun sin exigirle demasiado. espero que con este complemento la vida útil de mi amplificador se extienda un poco mas.

Mein Mann hat eine HighEnd- Stereoanlage mit Geräten vom Feinsten. Zum Geburtstag wünschte er sich von mir dieses Belüftungssystem. Er war begeistert vom edlen dünnen Design, der Qualität und der leisen, kraftvollen Arbeitsweise. Es dauerte zwar ziemlich lang, bis die Lieferung da war, aber das Warten hat sich gelohnt! Die Preis-Leistung stimmt, es gibt nur Gutes zu berichten. Ein Tipp: Vermerken Sie bei der Bestellung, das Sie einen deutschen bzw österreichischen ADAPTER benötigen! Dieses Belüftungssystem ist selbstverständlich für jeden, der Kühlung braucht, super geeignet. Mein Mann hat sich jedenfalls sehr gefreut.... 100% Weiterempfehlung!

配送後に早速取り付け、と言っても電源コードさしてアンプの上に乗っけるだけの簡単設置。ファンは４段階のマニュアル切り替えと温度上昇時に自動で回るオート付きです。しかもオーディオアンプにピッタリでした。夏場の温度上昇時のアンプの保守には必用と考え購入。静かでしかも強力なファンです。サンスイのauシリーズの幅とほぼ同等で、マランツのnr-1200では後方が１～２センチほどでますが、インシュレータはしっかり乗ります。見た目も豪華でこれからのオーディオライフも安心です。このシリーズ表示が出るタイプと無しのタイプがあるようですが、表示タイプは2～3万円位するので、表示無しタイプのこちらを選びました。買って良かったです。尚、防塵ネットを事前に購入していたので、両面テープで張り付け防塵対策も行いました。 ※１日使用後 オート設定で確実にアンプの温度上昇を防いでいる。温度が上がると自動で冷却、一定温度まで下がると自動停止！素晴らしいです。オートでは節電にもなり、こちらの設定を推奨します。因みに3台目のミニコンポ用にも追加注文しちゃいました。※2 使用後数日して判明した事があります。このファンに防塵ネットを着けていたのですが、説明書(英文字)をよくよく読んで見ると、何と冷却システムが一般的な冷却ファンと異なり、プロペラが逆方向についている事が判明(( 'ﾟдﾟ｀)ｱﾁｬｰ間違った認識してたよ！無線機等の冷却ファンは外気を本体に直接当てて冷やすので、これもそうだと間違った認識！実はこの製品、アンプ等の熱を外へ押し出し冷却するシステムだったのです。これでは防塵ネット着けたら駄目だろ！というわけで直ぐ様取り外しました。そのせいか頻繁に回ってたファンが取り外し後は、余り頻繁にには回らなくなりました。そりゃそうだよな！ネットつけてたら薄いシートを上に被せているようなもんだもんね！熱持つわな！照れ笑い((〃^ー^〃)！そう云うことで防塵ネットはいりません！訂正してお詫びします。メーカーさん！ごめんなさい！
