I just grabbed a +4800 X2 and a Zalman 9500 and I am ready to upgrade from my +3800 X2. I got a PC from Monarch Computer and it has a Thermaltake TR2TT A4014 TR2 M1 heatsink and fan combo. It has a "no-tool" relase system and the arm is in the down position. Ive swapped out processors in the past and it isnt rocket science, but I cant seem to figure out how to get relase the tension in the arm. Will not move side to side to release. Thermaltake has no info on it's site at all. Anyone have experience with these? Any help appreciated
