i just built my system in a chief tec case, its an xp 1700, dragon plus mb. i also ordered 4 of the panaflows that flow 24cfm, i figured two in and two out. but now i am debating between the glaciator and the thermalright sk6, any suggestions, i have read the reviews and stuff, but now i am looking for personal prefrences. anything has got to be better than the retail heatsink and fan i have on there now. thanks in advance for your suggestion
