My new HP Microserver N36L with a noisy fan. The fan rotates with ca. 3000 RPM. On the HP homepage the server is promoted with 22 dBA noise level which I can't reproduce. The fan rotates constantly also if the OS (WIN 2008 R2) is started.

Video von meinem HP Microserver N36L mit einem sehr lauten Lüfter. Der Lüfter dreht mit ca. 3000RPM. Auf der HP Homepage wird der N36L mit einer Lautstärke von ca 22 dBA angegeben, welche in diesem Video mit Sicherheit bei weitem überschritten werden. Die Lüfterlautstärke bleibt konstant auch nachdem das OS gestartet wird (WIN 2008 R2).

  • hello... contact your HP Support center and they will replace the fan (or alternately contact hp partner where you bought it). these things can happen, technology is not perfect... had the same issue and had fan replaced immediately by HP technician at service point

  • It's the missing PWM signal that causes your fan to run on a three-wire-basis! Because you have constant 12 volts the fan runs at maximum speed without its PWM commands from the mainboard.

    Das fehlende PWM-Signal veranlasst deinen Lüfter auf Drei-Draht-Betrieb zu laufen! Da der Lüfter konstant mit 12 Volt versorgt wird, dreht dein Lüfter ohne die PWM-Befehle vom Mainboard auf Maximalleistung.

  • That's abnormal!

    Maybe your wife started wacuum cleaning in background...

  • would a CPU cooler at 22 dBA be annoying?

  • id pay for that! sounds sick1!

  • I'm not obsessed with noise really, but that would annoy the hell outta me. In a totally silent room I can hear mine's PSU fan from 3m or so, if I am really listening but it's not annoying even from 1m. I practically can't hear the system fan.

  • Probably just a thermister failed inside the rear fan. I don't think the fans are motherboard controlled, only sensed. As the previous poster said, mine is just above silent with 4x 5K3000 drives. Sorry you had an issue :-(

  • Did you get this resolved? Mine is super whisper quiet. I upgraded to 8GB Ram, and 4 x 2TB drives, RAID1, Windows Server 2008 R2. You need to put your head almost right up on it to hear anything. Yours is just ridiculous. Did HP customer care handle this for you?

  • RMA

  • It should only be spinning somewhere between 900 to 1,000 rpm. I'd be taking it back IMMEDIATELY. Don't keep it with a fan that fast.
