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.

First, be careful aiming a fan at Any piece of gear. IF you are somehow interfering with the natural convection (hot air rising) currents that the heating of the piece causes, you could actually make it run hotter, or too hot.

Premium (read as HEAVY) power amps like the Krell should be able to take any power demands in stride. Especially when used in an open installation. The Krell 300 or 400 integrated is a possible exception. My brief exposure to one (the 400) showed it to run bigtime hot. For my confined rackspace, that was a deal breaker. The Stereophile test confirmed my impression when they remarked on the heat of the amp after the pre-conditioning period before bench measurements, Worse Case Scenario, to be sure.

How much are you asking of these amps? I don't see how you should be able to put a dent in 'em....... If they have not gone into thermal protection then there is probably nothing to worry about.

I believe there was a thread somewhere that some folks loosened the fin bolts a smidgeon and that fixed the clicking sound. I havn't tried it as I just live with it. My FPB300cx clicks only a tad bit and only on occasion so I just leave it alone.

My 400Xi runs hot...even toasty in standby, but that is why is sits at the top of the rack, nothing hinders it.

I have had mono blocks that have run much hotter, but they like that tropical heat level, that's the way they were designed.

Besides...where am I going to put my cat?

All electronic lifetimes is lowered by heat.

The only thing I know of that really likes heat, is indeed, the Cat.

I had one sponteniously combust on me after it lay in front of a fireplace for a couple hours.
