## Description

AC Infinity AIRCOM S9, Quiet Cooling Fan System 17" Top-Exhaust for Receivers, Amps, DVR, AV Cabinet ComponentsA quiet cooling fan system designed to be placed on top of AV components such as receivers amplifiers and DVRs. Maintaining an optimal temperature for components prevents overheating ensures constant performance and extends their lifespan. The controller on the front of the cooling system features a smart thermostat trigger and fan speed control. The steel enclosure houses three dual-ball bearing fans that pulls heat out of the component and exhausts upwards. Its low-profile design enables the unit to fit in tight spaces. Includes corded power adapter to plug the fan system through an outlet. There are three programming settings available which includes two temperature trigger modes. The fans can also be set to run continuously or be turned off. Four fan speeds are available for each active mode and will determine the speed at which the fans run when they are triggered. This ensures optimal airflow and noise levels for your application. Each system features dual-ball bearing fans rated at 67000 hours and are certified by CE and RoHS. Fans contain a PWM-controlled motor used to minimize noise during speed variations and are suspended in mid-air with silicone mounts to absorb vibrations. A low-profile design allows the unit to fit in applications with a limited height clearance. Aluminum and steel construction enables additional components up to 30 pounds to be stacked on top. ;

Review: 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.
Review: 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.

## Questions & Answers

**Q: i have a denon avr s940h reciever in an enclosed cabinet with 4 inches from top of reciever to top of cabinet. Will the s9 or t9 work?**
A: 4" from the top of your receiver means only 2.5" from the top of the AIRCOM S9.  This may be too little clearance for a top-exhaust unit.  You say "enclosed cabinet."  I assume one side is open.  The hot air needs to vent somewhere.  If this is true then go with a front or rear exhaust system instead.  The AIRCOM S10 is the front-exhaust version and S8 is rear-exhaust.  Also, I like the S-Series because it offers all the control over the fans that I require.  The T-Series costs more and seems a little overkill.  Unless, however, you really like the LCD display.

**Q: Will this work in automobile applications**
A: It works off of 120.  You should call the company and ask them if they have fans for automotive applications.

**Q: does anyone use these fans in a stack? in between 2 components (amp, fan unit, avr for example)?**
A: As long as you have proper clearance I don't see why it wouldn't cool ok. I think it pulls air upwards better than pushing air but I have used it to push air up thru an amp.

**Q: Have a receiver in a cabinet with 3.5" space behind it to back of cabinet or about 5" above it to a glass shelf. Top or rear exhaust unit is better ?**
A: This unit exhausts from the top and  I have about 1 inch above the unit.  It works perfectly.  I’ve had no problems with the receiver overheating, since I purchased the fan.  If you have 5” above, it should work very well for you.

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！
