Scythian Problem in system

[GAINELL]

I ordered on Scythian PC look 2 ventilators ref. SY1225SL 12M. They are given to turn to 1200 rpm to 12V for a flow of 68 CFM
I thus assembled 2 of his ventilos, at the end of one week, with starting, a ventilo to be started has to make a noise of unbearable helicopter (that of the top). I thus said myself, I fell on a defective ventilator and I gave old. 2 weeks after same temp on the other that I had to place on the ventilator. meanwhile I had received another of the SAV of PC look and I had given a Scythian on the top Today eh quite same problem a noise as if the ventilator touched a fixed obstacle with moreover one speed has which goes down has 300 rpm whereas it is completely free.

Is there any problem with cooler master ?

Only one Magic when you have the capacity to grant it if you do not tighten it off enough has left the path wisdom when that functions and that nobody then knows why the tangents are the conical ones, it is not idiotic.

[GAINELL]

Yes that which was on the ventilator turned almost at bottom On the other hand never to try to connect them directly on 12V because precisely I want the monitor I suppose that it does not support the changes of tension.

Just to know if it's just an "incompatibility" with your machine
try another fan (not scythe) on the port before use will improve the diagnosis
you know exactly what to take away .
