Take the side panel off your PC and check if the fan is spinning inside the power supply. You will be able to see it.

Flip the case to check?

At those kinds of loads, less than half the capacity, these Corsair AX should be spinning the fan, just pretty slow. It should be no louder than a single one of your Velociraptors at idle, much less 4 of them, much less if any are actually seeking, not to mention the CPU and GPU cooling under load.

If it's spinning it would be very slow if at all.... it only spins up if it needs to.

OP, I can pretty much temm you now that the fan IS spinning. I suggest you either flip the case, or the PSU to see for yourself. thumb.gif
