I can put some #s on this:
-- Deopfer Monster 12u case power specs (per Perfect Circuit): Available Current: 8000mA @ +12V, 4800mA @ -12V, 16000mA @ +5V
-- my 12uMonster rack's row1 draw per MG: 1075 mA +12V | 487 mA -12V | 0 mA 5V | ... about average (1/4 of total below)
-- my 12uMonster rack's row2 draw per MG: 1496 mA +12V | 764 mA -12V | 0 mA 5V ... higher than average
-- my 12uMonster rack's TOTAL draw per MG: 4421 mA +12V | 2535 mA -12V | 0 mA 5V

So if my case has 8000mA @ +12V delivered by 4 PSUs (one for each row) am I maybe pushing Row2 too hard by using ~1500mA +12V?

"Careful...one of the standard MG caveats is that the current draw figures aren't always 100% accurate...or sometimes even present!" -- I hear you @Lugia. BUT if the #s above are roughly right, would we be expecting a heat problem?

I have some other cases that are NOT experiencing heat issues -- they get warm but not hot -- so I'm just hoping to identify and fix the issues going on with this one Monster case. Thanks!!
