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?

OK - Here is what Raymond, a servce rep and Krell said: Do not use fans or loosen fin bolts. A remedy would be to send in the amps to Krell for installation of heatsink tape. I am trying to find out if this could be a DIY.

He neglected to respond to my question about the origin of the word "Krell". I'll keep pushing.!! LOL!
Krell advises that the heatsink tape is installed internally thus requiring dismantling of the amp. Guess I'll just learn to tune out the click.
What is heatsink tape made of? If it is conductive you really should let Krell place it, otherwise you could be one hairball away from tradgedy.
Not to worry Mechans - I wouldn't dare try it as a DIY! LOL! I have absolutely no idea what the heatsink tape is made of . . . guess that would be another question for Krell.
