cooling my Krell monoblocks


I have been considering the purchase of thermalright PC fans rated at 50 CFM/24 DB to set on top of the monoblocks and draw heat out. Is anyone else doing this or have a better idea?

In reality.... if your amps are in open area... not crammed into cabinet. The manufacturer design does not need any additional cooling. They were made by top quality engineers who took the heat issue into consideration when they were designed.

Good Luck
Thank you for the replies - both make sense. One of the mono's "clicks" as it heats up and cools down but when I aim a fan at it the clicking stops - Krell says it is nothing to worry about but the the clicking is annoying and I find my ears "tuning in" to the clicks rather than the music or movie. BTW, the monos are out on the floor in open space, not in cabinets.
