Efficient Workshop Heating

Lofty, idle has no relevance, and a GTX690 has an unsealed cooler, at best about 25% of the heat will exhaust directly to the atmosphere, and it's a 300w card, so 2 of them at full synthetic loads will see 500-600w and bar the slight noise and vibration, that is heat one way or another.

The last dual chip card setup I had similar to yours was 3x 4870x2 and you couldn't hold your hand at the exhaust for more than a few seconds, it would certainly burn.

The program is CGMiner - you'd need to run CudaMiner on your 690's and you'd get around 600-800KH/s for your 600w consumption, - and if you want to give it a general stress test to warm things up OCCT's (PSU test) is great!

Michael, I'd need to know the molecular density and the adiabatic constant for the gas (plus the temperature) to calculate that right? - they should really rename it from "speed of sound" to "speed of molecules in a gas" - I think it makes more sense =)

Well skip got delivered today.

That will last about a week, took the skip back this afternoon, it's only 100 yards up the road and will get same skip back probably Wednesday or Thursday next week.

Looks a lot but it isn't, we have 3 wood stoves and 3 neighbours also pull out the same skip for their fires.

Good thing is there is no prep, people just take what they want and what will fit their fires. there is never anything longer than 3 foot and that will fit into the workshop stove OK as it's a top loader. All kiln dried beech, been 12 years since we have had the flues swept.
