bought one of these from ocuk last week, only just had chance to install it but it doesn't seem to be working:

1. it's a pwm 4-pin fan, when I insert into any headers in my mobo it turns for a few seconds then cuts out, repeats this every 5-6 seconds

2. i've tried it in all the 4-pin headers on my board, and also in some y-splitters which I have other f-12's in and it does the same thing

3. it's an 'industrial ppc' fan, which is different to the regular f-12's i've got - the board headers should be enough to power this right?

can anyone think of anything or is it a dud?
 
I believe the ppc fans have can stop and start constantly if their protection system is triggered, like short circuits and stuff.

If it is working in headers that work with other fans it may be that there is a problem with the fan.
