AX850 fan dont rotating

Hello Corsair team for a year now I have the AX850 recently I bought a new case and installed a 4 channel fan controller with temperature sensors, two sensors mounted on the exterior of the power supply. (above and on the side)

 

 

Then I noticed that the temperature starts from 30 degrees and raise to 40 degrees and usually remains at 40.

 

I think that's pretty hot then I check the fan of the power supply and

he dont rotating?

 

Now I am quite concerned that the fan is broken?

 

 

 

 

My system

Phantom Full Tower --Power Supply is installed on the ground.

2600K CPU

Gforce 570 GTX

Z68X-UD5-B3

Xfi sound card

Corsair memory

 

that is not really a lot of power consumption..

Use the link on the left side to get your RMA started and the PSU replaced.

No, 40C is not "hot". Load your system with a 200-300W load (run 3D Mark for long time) and then check if the fan works. But most times Seasonic X and Corsair AX fans are idle.

His PSU is already over a year old and that was before the fan-less operation at low loads versions were available.

 

I do agree 40c is not hot at all for a PSU, it was the fan not spinning is why i made the suggestion to have it replaced.

 

 

Just to be sure , what is the model number on the PSU?

AX850 does have fan-less operation at low loads. You can see it even on the box of this 2010 review of AX850 : http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story&reid=197 (a closer picture : http://i826.photobucket.com/albums/zz188/LlamaOps/IMG_1404.jpg ). AX750 and AX850 are Seasonic X-750/760 and Seasonic X-850/860 with minor modifications, and all Seasonic X series have sub-20% load passive mode.

Hi thanks for the replay i was very busy so the best think is i try to have mutch load and see what happens?

 

but good to know that 40° is not hot

 

at 170 Watt it should start rotating usually i think right?
