ARC Reference 10 melting polycarbonate cover

Any similar experience? The 6550c tubes are melting the poly cover in the first 7 hours of usage...

I thought I was going to have to buy a new rack as the one I have only has about 3" of space above the ARC and the next shelf. The poly cover was starting to bow above the 6550. A cooling fan solved the problem. I think the fan is a good idea even if you remove the cover. Cooler operation equals longer life.

It is very quiet and still puts out a strong blow. It is AC powered. The only drawback is I don't have anything to plug it into with a switch so it runs all the time. Still, it is so cheap if it wears out I'll just buy another. No more bowed cover.
