true some are on wood, fan is top side so I dont think it makes much of a difference vs the ones directly on metal rails, considering the high ambient temperature...in winter all will be fine. And they run a bit more than 80%...1000w evga's GQ, solid PSU, running anywhere between 750 and 930w depending if im dual mining or not. (at the wall, 120v, so on 240v its a little less due to better efficiency). Breakers all run at less than 80% all up to code, but the PSU's themselves dont really need to if they are quality (of course you are correct lifespan with high temp is shortened). Warranty is 7 years though...
Only if you register them. it is 3 years if you don't go to the website.
@ generalt when I pull in the car a kia forte if it was running for an hour and is warm it adds to the temp in the room.
At the moment I am very high power use on the 24/30 amp pdu.
I am at 21 amps is 21 x 240 = 5040 watts = about 18000 btu so the garage is 93f.
I am only mixing the air ie no exhaust out of the garage. and house ac is on.
So my house is
93-95f in the attached garage
80-83f in the 1 bedroom den/ walkout basement
77-79f in the upper level 3 bedrooms dining living kitchen
This is temporary
the r4 is 4 amps and I ship it on Monday
one pc 2x 1080 ti's is 2 amps I put it in my friends office
so I will drop down to 15 amps by monday.
I have 2x 30 amp breakers at 240 volts I could run 10000 watts in the house.
I have done it, but that is 38000 btus.
I simply don't do this I put gear in the solar array and in my friends office.
The solar array is 9k to 13k
MY friends office can do 2 r4's or 2k
I sold the 2 r4's
SO his office will have 3 pc's using 1600 watts.
each with 2 1080 ti's
