[QUOTE="Tim McCulloch, post: 93074, member: 67"] Re: Heat on IT8000 Amps Hi Chris- Original I-Techs seem to put out a fair bit of heat when idle, but [I]I don't recall the top or bottom of the case seeming unusually hot[/I]. The exhaust... that's another story. At idle they seem to kick out a lot heat compared to A/B or H class amps. I monitor the temperature status of our I-Techs via System Architect and it's rare that any unit exceeds 60% of its thermal capacity for very long but we don't do EDM or other genres that include constant-level signals. YMMV and all that... When we adopted I-Techs for our VerTec rigs we took a cue from Schubert Systems and racked only 4 amps in a 16 space rack - total of 4 spaces for AC, i/o and data connections, and blank spaces between amps. The racks have back doors with 4 exhaust fans and a controller. Dirk Schubert was adamant about cooling - we've never had a heat problem with this configuration. With the custom doors, fans, controller and labor we're paying about $350 per rack for cooling. As a stage hand I've set up rigs with 6 or 8 I-Techs in a rack. More, bigger fans.

What's your application, and what have you considered for cooling and electrical service? [/QUOTE]
