hard to compare loh ..

these are result of different forumer with different CPU and clock speed ..

from the thermalright official site, the installation process shouldn't be too harsh..

it only requires remove of mobo like most other performance cooler.

put the heatisink in place and tighthen the nut from the back of the mobo after the retention bracket ..

that wont be too troublesome compared with having to screw down the mounting bolt ...

hmm ,, unless it is those with higher than 60cfm fans you are referring to else it wont make much difference ..

since most chap ayam brand also got quite a strong cfm around 40 to+ loh.
