If you want to run RTTY or other high-duty cycle modes with more than about 25 watts for any length of time, you need some supplemental cooling for the K2. A muffin fan like you've described would be perfect. I used a muffin fan much like yours for a while, and then I broke one of the blades and had to replace it. The replacement is a 2 1/2" muffin fan mounted the same way. I've been able to run 50 watts RTTY through many contests with no ill effects.
