The Arctic Cooling RC Heatsink and RC Turbo Module PWM RAM Cooler have been updated for improved performance. The Arctic Cooling RC Pro and RC Turbo Module PWM RAM Cooler combo provide passive and top-down active cooling solution for enthusiasts who need better cooling than what stock RAM coolers provide. The Arctic RC Pro heatsink now features a 3-piece screw locking mechanism that was absent in the previous Arctic RC RAM heatsink. The new PWM version of the Arctic RC Turbo also improves upon the performance by getting rid of the 4-pin Molex design and using the new Arctic PWM Sharing Technology, which allows multiple PWM devices to run from a single 4-pin PWM header.///"
