Me too. Having worked many years installing and setting up home theater systems and related gear, I've always been surprised at how many folks are willing to spend thousands on excellent gear but are reluctant to spend a little more on Uninterruptable Power Supplies. IMO there's no better surge protection than a UPS, and the added benefit of having no recordings lost or interrupted is just icing on the cake.
With my TV and AV receiver turned off, a 650w unit on the EC will power everything else up for days. I'm a big fan of APC UPS's, but surely others also make quality units.
As for running temperatures on the 7400, after what several posted here about laptop coolers I went looking for one but didn't find any that had their own separate power supplies -- USB only. Then I remembered I had a 6" fan with a clamp at home, and since my EC isn't enclosed I was able to clamp it onto a shelf and aim it at the 7400.
Before I did this I used an accurate IR temp gauge to measure temps. My 7400 was already sitting raised up ¾" on blocks. Highest temp seen was 118F, around the middle-left side of the top of the case. With the 6" fan running at the lowest speed, case temps dropped to ambient room temp, about 74F.
Performance differences I could perceive are minor, but they're there, mostly amounting to a slight improvement in response to remote inputs on nearly all menu screens. Time will tell if other issues show themselves improving.
The differences are minor enough for me to be unconcerned about a customer having one run at 118F, but when a small fan improves performance even a little bit -- and considering that virtually all electronics would choose to run cooler if given the choice -- what the hey... the fan stays.
