I put a Galaxy GC88 cooler on an 1800+ TBredB, and the die being so tiny, the hsf basically "balances" on it. As in, if I push any corner of the hsf down towards the mb, it tips in that direction. I can also twist the heatsink around (its a 1 clip/side design, so it can rotate around the 'balance' point to some extent). But the hsf cannot be pulled off the die, since the clip holds it down firmly. It just bothers me that this happens. My old Taisol with the 3clips/side design wouldn't budge in any direction once it was on the socket. My current computer makes me feel like I'm watching a circus act everytime I look at it.
