Yeah, I would most definitely test it first before i put it in with my most precious of cpu components. I wanted to see if it was possible. The 12 volt version is a little slower but it still pushes 235 Cfm's. Ohh it is tempting to try.

But look at that big gaping dead zone! I mean really, the bulk of the part that's actually spinning is the motor. Don't they have an EM fan of similar size? Now that would be sweet. And then putting it onto the side of you case and ducting it straight to your heatsink.

Y'know, I think I'll replace my Prometia Mach II's stock fan with the 48V model! And pump it with Freon R-12 (licensed) like I did with my VapoChill.

Hey Tachyon, why haven't you ever posted pictures of your super-extreme -80C cooling system?  Even a MBM&WCPUID screenshot would be pretty awesome

There is no way (besides using the -12 volt rail) to get 24 volts from two 12 volt rails.  You'll have to get a dedicated 24 volt supply.

wiring it to two 12v lines in parallel to its positive line will still give you 12v.

wiring it 12v in series with the thing will give you a difference of 0v and the thing won't work.

however, you can run the 24v one at 12v and you're going to have a powerful, and quiet fan.

and the feathering at the end is reputed to reduce noise.  I'll pull up the link later.  something about vortexing.

That notching was/still is? used by the Navy on their subs to reduce the turbulence and therefore the noise of the propellers.
