SO, should the fan spin up for a second at power up or not?

Mine doesn't, so I'm thinking I should return it.

Can ANYONE advise please?
Don't worry about power up or power off. If the unit is not getting HOT and the fan spins under load then the PSU is working properly.

Thank you very much Yellowbeard!

I noticed that it did spin up on power up (for a second) but it doesn't anymore.
Last time it did, it sounded like the fan is rubbing up on something.
Perhaps that's preventing it from spinning up.

It did get rather warm on the "non-fan" side when running a few loops of 3dMark 11.
I could not get it to spin up under load either.

The rubbing sound it made while trying to spin up, in conjunction with the warm temp,
doesn't make me feel too confident.

Gonna swap it at the store this week.

I appreciate you getting back,
Tom

Tom, I would agree that it sounds like your unit should be replaced, please let us know if you have any problems with the replacement!

Default Ax850

Hey people,

Happy Holidays and a happy new year too all first of all.

Just got my new PSU today the nice looking AX850.
Noticed that the fan wasnt spinning on it there and a wee squeal noise now and again. I've never heard this before!!! So after looking up that the fan only spins as required, I decided to stress test the machaine for a hour with AMD Overdrive to see if it kicks in.

3 Minutes later computer shut down no warning just shut down complete. Now I cant get it back on!!!!! (May need to wait a few minutes, hours??? Who knows) Never had anything like this before not one problem with the other PSU that was in it the VX550.

Has anyone else had problems like this or is this just me.

Thanks for any help in advance.

ThePhenom

Ok update here for you.

I left the computer last night while I cleaned up lol. Came back to it a few hours later and plug it back in and it started up no bother. Left on for a while all seems ok!!!! Stress tested it for 10 minutes this time no issues fan started spin when required and no squealing noise. YEAH!!!! All seems ok. Sorry to bother anyone that gone off to have a look into this. Happy Holiday and all the best for 2011.

Hi Guys, just thought I'd give you an update for the users and Corsair's sake.

On further inspection, it turned out one of the (thicker black) cables coming
off the PCB was communing up, and preventing fan blades from spinning.

I pushed the cable back down through the fan grill (while the PSU was unplugged)
and tried to push it into a position so that it wouldn't pop back up.

The fan now spins when it's supposed to, but needless to say I returned the PSU for a replacement,
as I believe the PSU was un-necessarily strained during my attempts to get the fan to spin-up.

Hope that helps,
Tomek
