so a shout out to the legends testing please try the killer delta fan and over clock the unit.
I would love to see the user's show the over clock potential. maybe a better fan for the under clock guy like my self. for that matter maybe someone would use the super powerful monster delta fan for over clock . it moves 25 percent more air then the stock fan. mr teal is really handy with gear.
this is the fastest fan around. would be the best for over clocking maybe??

Like a lot of fans tailored to moving air without restriction they have a shelf on their pressure-airflow curve, and once you get to around 0.5"H20 they quickly lose any advantage they have over a fan designed to really push air. The downside is the QFR is louder, spins faster and uses more power.
No what you want is the PFC1212DE-PWM or PFB1212UHE-F00 (if you want non PWM without a connector)

Problem with the SP20 is it uses a custom header plug onto the controller card. Shouldn't be a problem for you chaps handy with a soldering iron though.
I have a pile of the TFC1212DE's which are the same fan, and I find them a bit of a waste. If you look at the
datasheet, you'll see the same shelf I was describing with the AFB. Compare that with the
QFR1212GHE where the P-Q curve is actually convex.
At around 14mmH20 the PFB is at 150CFM, while the QFR is a little lower but similar. From there the curves are pretty similar with a slight advantage to the PFB, but not one that justifies its more than twice as high power consumption.
The biggest benefit to the PFB1212 is you can get them used on eBay for a couple bucks each.
