Our one gripe is the Crazy Cool plate on the back side of the board underneath the CPU socket. While we noticed this option worked as well if not better than the ASUS Stack Cool 2 system, the plate is just thick enough to rule out the usage of several aftermarket cooling systems that require the use of a back plate. Granted, some quick and minor modifications to the attachment screw lengths worked in several cases, but for a high end board Gigabyte should expect the user to upgrade the retail CPU cooling system.
It doesn't have PWM and it's noisier than the Cooler Master but cools better. It's also bigger and taller.
The LGA 775 cooling system is a bitch, especially with big bulky HSFs. The mere thought of removing one sends chills up my spine. In fact I ruined the clips on the Samurai while attempting to remove it, but Scythe tech support replaced them for free.
