cancel the order.
although it looks amazing, a simple google of 'cooler master geminII review' will surprise you...Apparently, it's a horrible cooler and alot of ram wont fit under it.
I like the Tuniq, but the Thermalright Ultra Extreme even better.
The most CFM you will find is probably 104, and the Thermalright Ultra Ex. was claimed the best in some article. For the TUE, you have to buy a fan anyway and drop it into the center of the heatsink.
I found at 150 CFM fan 120mm x 25mm.
The Cooler Master GeminII Dual 120mm, may not be the best but it certainly looks pretty awesome, it seems to have a wow factor to it. But i would keep the tuniq if i were you.
I don't like the way it looks, it looks just plain weird. A TUe would look better with a blue LED fan on it.
