TS-859u - System Fan 2 replacement?

[sgatke]

Hi everybody

Our TS-859u is now reporting "System Fan 2 failed".
Does anyone know of a replacement fan that we can plug in and use?
I tried looking at shop.qnap.com but there are no replacement fans listed for this model.
It appears to be 8x3 (cm) smart fans so I believe it should be possible to use a standard fan from e.g. CoolerMaster.
But, I am not sure what kind of connector is needed.
Is it 3-pin? 4-pin? And with which connector type?

The unit is in a production environment and I would very much like to keep it running until I get a new fan.

Any help appreciated, thank you in advance.

Please note that the airflow of the fans is much higher then normal PC fans.

Thank you.

Do you know the specifications?
I believe the connector-type is PWM, can anybody confirm this?

I've replaced mine (on a 870, never replaced the ones one my old 659 Pro+) with two Nexus Real Silent D12SL-12 PWM, min 15.5 dB, max 76 CFM, much better then the original ADDA AD1212LB-A7BGL min 32.9dBA, max 72.3CFM, they also are connected with rubbers instead of screws which will save fan resonation.

Hi,

I also had this issue on one of my 859 pro +

I was advised to use Coolink SWiF2-12P 120mm PWM as the ampage is closer to the obsolete AD1212LB-A7BGL

It seems to be working fine but I'm getting a fan error message. Smart Fan Control: System fan failed so maybe I was advised wrongly.

You can get the full fan spec from http://www.mouser.co.uk/ProductDetail/A ... Wm38aHkQ==
