<< looks simple and effective! nice work. Would this also work on the circular heatsinks like the volcano? >>
From the article, as long as U hv a 60 X 60 mm "fan frame"...u will be able to mount the 80 mm fan on it. The volcano is no prob.
But because the 60mm "frame" will block some CFM off the 80 mm fan, the actually cooling prowess may drop.
