I just bought the MIME to fit the above board as noticed it was on the compatability list in the forum.
However I cant fit the cooler so it blows to the rear of the case, I have to mount it blowing upwards. rotated 45 degrees. The reason for this is a capacitor on the board is fouling the push through clip in that corner. On this board ( REV 1.2 ) there are also capacitors / chokes that are about 1.5mm too tall to allow the heatsink base to sit correctly.
You will know it wont fit when you hear ferite grinding on steel, that will be one of the chokes being swuished

The Mime does in fact fit rotated 45 degrees so its blowing upwards and there is no difference between it blowing to the rear on my deceased gigabyte P35c DS3R that the MSI replaced and blowing upwards on the msi P35 Neo2 FR /FIR its still 33c idle and 46 full load.
I have marked the offending cap on the attached image.
Brilliant pice of kit by the way, thank you Scythe !
