cooling my Krell monoblocks

I'd like to keep them on standby but it is expensive to do so. I agree with Davidbigeye - it definitely is bloody annoying but so is the fan that I have been blowing on them!! I thought that perhaps some small silent PC fans might create just enough cooling effect to stop the clicks.

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.

Loosening the fin bolts a "smigeon" is an interesting thought - can't hurt to give that a try. Collectively you have convinced me that a cooling fan is NOT a good idea. These are Krell fpb 350's that I really like - a while ago I let a pair of fpb 250's go and seriously regret it - they didn't click!! At least I now know that I'm not the only one suffering with clicks disease.

Thanks to each of you!

I'll contact Krell and find out what options are available and let all of you know the reply. While I'm at it I can ask the D'Agostinos where the word "Krell" came from. That too would be interesting.

Classicjazz - do you set the Noctuas on top of the amp to pull heat out of the inside or along side to pull heat from the fins?

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.

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.

Wow! I have learned WAY more than I bargained for when I was only looking for info about cooling my Krells. LOL. . . From what I am reading The Krells may still be alive today, in our living rooms . . just waiting for their supreme commander to give the signal to morph into superior beings and "think" our systems into something way beyond our wildest dreams. . . or turn us into molecular dust.

HAHAHA! Mechans - you are on the right track - I am happy too and don't see the need for change . . . .except that I just upgraded my headphones and headphone amp and there is the dire need for a better . . . . . .other than that, I'm done . . .today!
