i was just going out tomorrow to buy the vantec tornado 80mm, i was thinkin of 2 to start with (1 exhaust and 1 intake), i got a slot for a 2nd exhaust fan as well, i'll try another exhaust if my case temps are still high. i bought the vantec aeroflow heatsink/fan, i'm not too impressed with it. nice heatsink but i think the fan could be alot more powerful. the fan is not a 80mm on it. i think the stock intel heatsink has a 80mm fan on it. i'll try a vantec tornado on it if i can. maybe it will be better than the aeroflow??
