My vote goe to -
SK-7 w/ Smart fan II
That's an interesting article about the
SK-6+ but
I'm not sure it's a good idea.
I have done that very
Sk-6+ mod myself and the results
were rather dismal. The larger dead spot of the 80mm
fan made the set-up less efficient than with a 60mm.
The only advantage was less noise from the larger fan.
Also did the exact same thing with a 92mm fan on an
SK-7
and the results were similar. The 80mm actually gave lower
temps than the 92mm. Both were
Enermax adj. fans.
Now, if we can move the fan farther away to eliminate the
"dead spot" below the hub, then we'd have something.
How about a piece like that angled
ThermalTake
"ducting mod" but made to adapt a 120mm fan instead?
