i have one of those Aero 7+ fans... but it is the one where they sell them individually as blowers. Im using it for a SLK or Swiftech mcx, but the RPM/CFM is much lower than the actual Aero7 HSF. So my solution is to power boost is from 12v to somewhere around 14-16v....

anyone know how to do so which out killing it?

i am also using an Enermax fan/temp controller/monitor.
 
-5v and 12v makes 17v... that'll give you a more than double boost... you can pull the -5v off of the atx header..
 
which one is the atx header? the main power to the mobo or the sub connector to the mobo.... maybe a picture or something might be easier to locate this booster key
 
My power supply rates the -5V at only 0.3A. I couldn't find any exact numbers, but from what I've seen the Aero 7+ blower takes more than half an amp. You might burn up your power supply if you connect it that way - check its ratings and be careful. My -12V is rated 0.8A, but if that's shared with anythng besides your fan you might be in trouble.
 
welcome to the forums dickie!

why dont u see how it performs on default first. maybe thats enough?
 
thanks for the welcome, Ryuen. Btw, nice avatar!

I have used the Aero blower using my Enermax fan controller, where the max speed is equavlent to the independent form. i believe if i ran it independently, it would run at ~10CFM also. The problem is that I dont see how could i boost the voltage if it is connected to the fan controller; it might screw up the controller. Anyhow, here's the specs to the Aero:

Size: 80mm
Bearing: sleeve
Air Flow: ~10cfm
Rated Voltage: 12V
Rated speed: 1,900rpm
Input current: 0.30A
Input power: 3.6W

(it does not come with a speed adjustor)
