Okay. I'm looking at getting myself a new cooler. 1, Now i have a side window so I'd like it to look good. Preferably blue leds to match the rest of the case. 2, I dont want it to be very heavy. (bit worried about that) not much over the 500g recommendation please. 3, I am also worried about clearance. I have had to cut the corners off the freezer 7 pro fan and it literally just fits between the mobos heatsinks. 4, it needs to blow air from front to back (i.e not at mobo) 5, I'd like it to have a PWM fan to work with the Asus Q-fan thing in the bios. The freezer 7 pro PWM fan works really well with this feature 6, i would like it to be compatible with a 400FSB quad at about 3GHz. (i have quite good ambient temps here. Internal case temp measured at the top of the case is currently 28.5*C) i have looked at the Zalman 9700 and Asus Silent Knight II. I am a bit worried about the clearance and weight of the zalman, but I'm also worried about the depth of the Asus, is it going to hit my exhaust fan?? Any help appreciated! i always leave thanks for useful posts!! Cheers!
