ARC Reference 10 melting polycarbonate cover

I have a Ref5 SE that has the same polycarbonate cover. It is sitting on top of my rack with the ultimate ventilation. The cover is STILL WARPED! It has nothing to do with adequate ventilation. Lostbears nailed it, it's the 6550 power tube. Flipped it over and in 5 minutes it bowed again. I am ordering a metal cover to replace the plastic POS!

Be prepared to spend $250 for the metal black or the poly, and $510 for a silver one...

Lostbears, sorry for the delay in responding. But, thank you for your response. I have been told that there is a difference, but by a dealer. I appreciate an unbiased experienced response.

I use the Enermax 120 mm fan. 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.

LeoG, Thank you for the information. Just curious if that is retail or dealer cost? Who pays msrp anymore?
