Yes I did see that thread but I can't really cut a hole in the ceiling. I search the forums a lot and didn't find much HVAC info surprisingly.
I believe during the summer you want to exhaust outside and during the winter you want to exhaust to the cool attic.
do you only have that one window?
it's too small for how I vent room, but I guess you could buy some cheap window ac?
oh, nm, i read on
with two windows, why can't you just put a fan in one window, seal off the rest of that window, then vent out the second window?
Too sum things up. I'm going to need central AC on for my family to survive the summer. I'm trying to come up with a plan to efficiently exhaust the miners heat without wasting my AC and driving my electric bill even higher.
Wouldn't using a window fan in the non exhaust window be blowing hot outside air into the room? I figured the best solution would to just simply exhaust the rig and hopefully my central AC keeps things cool but I know nothing about HVAC.
yeah, i live in texas, sometimes it's 110oF outside here, but i was still able to keep all my cards at or below 80oC all last summer (except for once when one of my 5970 fans busted and when i went in there it was at like 105oC, hashing away at 50mhash/100mhash, throttled etc).. they only hit 80oC on the hottest days in the afternoon, most maxed out between 70-75. you'll probably need to lower the voltage. 110oF is 43oC, which was a lot cooler than the cards were running at. you'll want to make sure you have good PSUs or they'll either be incredibly inefficient or just die in high ambient temps
some of that hot air escapes into the house, but not a whole lot, assuming that the only entry point to the rest of the house is the door to the room (yeah, we can assume a few cracks in the ceiling etc). you can buy (or make) something to seal off at least the bottom of a door. some air will escape out the side unless you improvise on that, not that much though (if you have proper exhaust)
i only have one window, you have two, so just put the computers between the two windows, you dont need a fan on the second window. use a piece of paper to determine how far to open it, likewise if your sealing job on the first window isnt so hot, you can use some paper or a napkin or something to make sure air isnt escaping from that window
i wouldn't get too complicated or spend a lot of money on same fancy setup, since it's unlikely you'll be running the GPUs for more than a few more months?? unless you're a believer in scrypt alt-currencies
