Frostytech used a 80cfm fan when testing the Prolimatech Megahalems ,Not my best choice for a fan on such a excellent CPU cooler as the Prolimatech Megahalems and the Tuniq Tower 120 Extreme CPU Cooler comes with its own fan and if you do your research on the fan you will see this: MFDB fan Specifications:Bearing Type: Magnetic Fluid Dynamic Bearing
Rated Voltage: 12V DC
Rated Current: 0.26A (Max)
Air Flow: 90.65 CFM (Max)
Noise: 16-20 +/- 10%dBA
Speed: 1000-2000 RPM
Life: 50,000 hours
90 CFM gave the Tuniq a .9c lead over the Prolimatech Megahalems with their 80 CFM fan. I personally do not think that was a "fair" comparison between these two coolers.
