I'm curious to see who else is planning on venting their mining rig to the outdoors.

According to the wiki page, that's a max of 375w per card. 1500w just to power the cards.

That's converting 1500w of electricity to heat, 24/7. It's like turning on a blow dryer and just letting it sit there.

Water cooling them will just move the heat from the cards to the radiator. (water pumps also require power and generate heat.)


Well the stock TDP is 375Watts, you will get terrible hashing rates stock though. Overclocked it can do even more wattage. In fact the ATX design limit is 375Watts to the card (75 + 150 + 150) which is closer to 450Watts from the wall per card (max).

Just dig a hole in the ground and throw your PC in there. Best cooling solution Tongue
