Interesting -- the RASA and other kits -- for the price. About double a high-end heatpipe cooler.
I notice that ThermalRight's IFX-14 design has been resurrected in the Silver Arrow and the Noctua-NH-D14.
There is a limit beyond which forcing more and more CFM's through either radiator fins or air-cooler heatpipe fins won't yield much more in heat removal, but you'll go deaf trying.
First, the wattage is insane. You might as well get an auxiliary power supply just for the fan and other periphera.
What was it -- 252 CFM? You could get past 150CFM with a 120x38mm Delta Tri-Blade, and the wattage is closer to 10 or 11 watts running at maybe .85 or .90 Amps. And it would still be quieter.
So, I have to say . . . "Bad idea.. . . "
In my newest machine, the beefiest fan that's in it is a Panaflo NMB-MAT 120x38mm (single case exhaust). I think it runs at 0.6A @ 12V, while a comparable San-Ace 120x38 is 0.4A@12V.
The rest are either 240mm Coolermaster fans that came with the HAF-922, or the Noctua fans on my NH-D14. And I think I can get rid of at least one Noctua fan without any increase in temperatures, a slight decrease in noise and power draw.
It's all about thermal resistance, air flow, power consumption and decibels. Minimize the first, maximize the second, and attempt to hold down the last two. But with a fan like that, the air flow doesn't buy much except for increasing the wattage and noise.
