i remember reading that thicker fans (more presure) were better in our application
ebay
the price is right
i'm running 2
thermaltake a1926 at 5volts pushing into pair of BIpros
the rads are in series
noise is my biggest issue - what i'm running now i can't hear but if i could get slightly better temps, i spend a little money
ps.
to anyone looking for a great looking quiet 5v 120mm fan i high recommend them and as a bonus the LEDs are about as bright as at 12v
airflow, however feels very weak
