My problem is i have an 80mm adapter and 80mm fan on my 60mm*60mm heatsink. The cooling works fine but the problem is as soon as i put the side of the case on the temps just keep rising and rising. This is because the fan is so close to the side about 2" away. The only thing i could think of doing is drilling holes in the side of the case. Or making some sort of duct which i have seen other people do but i just dont know where to start and which is the best idea.
