Actually, I'd say the Arctic Cooling Freezer is a bit smaller than the Zalman, and can fit into alot more cases. Yours lies flat though, so it seems a bit smaller, but the size of that heatsink...wow...
I will do
For the most part, it should only have to spin at 1090RPM which is much less than my standard heatsink/fans doing now, to get it alot more cool.
I'm going to invest in some new case fans too. I'm going for performance vs quiet ones, so at least 25CFM (cubic feet a minute) of air movement for the 80mm, and at least 60CFM for the big 120mm one at the front.
I'm aiming you see for room temp matching the inside temps, which will need some pretty good fans, but I'd rather not my computer sound like a jet fighter.
I mean, I have a massive room fan that I place sometimes at the back of the computer, blowing in through the fan holes, and the temps shoot down to room temp, but that things so noisy!
