I used a Silverstone FT02 instead of the Nofan case and removed all the fans. The rotated motherboard means that the heatsink, PSU, and GPU aren’t all one above the other so vent their heat separately.

HAAASWELL it is a cpu AAAAS WELL.
On topic: Check out Scythe Infinity or Ninja.
Same result with better compatibility. I am running an Athlon X2 with 2,5ghz in half passive mode (one system fan installed) with an Infinity 1st generation.

Sorry but we didn’t have time to on this build as it was already late because of the incorrect heatsink that was first shipped.
If we do another in the future we certainly will as we are interested in the results/differences between the 2 as well.
Thanks

I´m using that older style cooler on a Core i7 machine that I built as a silent microphone  recording computer. These mics pick up ANY noise such as refrigerator, commuter buses, creaking floors and not least computer fans, mechanic hard drives and so on.
So this was a revelation. You come down to experiencing the noise inherent to your own body,,,,,I run OSX on a i386 type microATX motherboard.
The cooler occupies the slots of some of the expansion slots but I am happy with just the passive cooled graphics card as extension.  Best computer ever with triple displays.
The cooler wouldn´t cope with an i7 running all cores full throttle but that is a rare case so no issues. NOFEN / NOFAN is a top ranked supplier in my book.

Did you guys do any comparison benchmarks for this setup vs a fan cooled PC? I’m interested in what that Fanless Heatsink is capable of.
