I have the aluminum model. Nice unit, but the hs seems a bit rough on the chip. First of all clamping down on the a64 with the hooks seems like you are going to crack the motherboard. The amount of force just seemd unecessary. I did it by the instructions, but it had me worried there. I never used half of that much force with my alpha pal unit. Secondly, clamping an 80mm tornado to the unit was fairly easy, howver even with the vibration damper, I think the fan noise just screams even louder than it did with the alpha pal. Moving from a metal rod unit to a metal fin unit is probably creating some reed effect. I'll probably have to get a larger 90mm fan for this one, although I'm almost used to the noise now.
