ARCTIC P8 Max - PC Fan, 80mm High Performance Case Fan, Server Fan, PWM Controlled 500-5000 RPM, 0dB Mode, Dynamic Fluid Bearing - Black

Pression statique (le critère n°1 pour moi sur mon projet) ≈ 5,3 mmH₂O, donc très puissant. Je le mets à 60%. Il est très silencieux a cette vitesse. Si vous le mettez à 100% il fera du bruit (très supportable), mais on ne lui demande pas d'être silencieux mais puissant et il fait le job!

good value. I only get range 1500-4600RPM (PWM 25%-100%) in my high-static? application as exhaust fan for a stuffed small drive rack (the Rack-Choice with 5 removeable trays). This fan is supposed to run down to 500RPM but I have never seen that. This fan is excellent to replace the noisy OEM IFF you route the fan control out of the drive rack, to a separate fan controller like the motherboard or a manual PWM fan-control card or dial. This fan is not really happy with 0-12v control since it tends to gallop (speeds up and down in a cycle that varies with voltage, typically full-cycle 5-10seconds, but it is not loud). I assume the fan internal PWM drive circuit is dropping dead and waking up when you lower the 12v supply voltage. PWM control is as-expected, good. At 100% this fan is plenty loud and flow is good, but I do not need that, except for calibration and emergencies. Good PWM fan for active temperature control with high-static, keeps the noise down most times.

excellent swap out for lower-power server setups. much quieter than the stock fans, use less power so they happy to run multiple off a single regular motherboard header, but they still max out near 5000RPM without excessive noise for quite good airflow. Seems like a perfect upgrade for 80mm server builds that don't need jet engine airflow but still need more than a Noctua 80mm would offer without adding much more noise. Time will tell how reliable they are, but i've used Arctic in the past in normal builds and they lived the life of the machine, but in a hot 24/7 server it might be a different story. we will see.

自分は低回転なので分からない 評価を見てみると初期不良率が高そうだ それを除けばコスパは良いらしい noctuaが高いと思う人はこちらへ

Bought for itx build pc. Tried a slim version but this is better, great gusts of air relatively quietly. Splendid.
