Re: [ANN] Spondoolies-Tech - Best W/GH/s ratio

When ambient is at an acceptable temperature, you just need ventilation. It doesn't matter how much heat you put into the air if you can simply substitute that air with ambient temp air.

You think if even is +40C?

Yep.

It doesn't matter how fast you wee into a cup, if I keep replacing your cup with an empty cup, you'll never fill it.

not quite a correct analogy.

Ventilation does not prevent turbulence. Air can be travel inefficiently that hot air got suck back into the miner .
You need to build a ducting system right at the rack. Thats the only way to control direction of air. Remember folks, you need ventilation and air direction control to be effective.

You don't if you have floor to ceiling double ended ventilation. Ie a door on one side and a door on the other....

I have my miners in my garage and this will be the first hot weekend of the summer. I'm hoping that by opening my garage door a few times a day I can recycle the air. Its north facing and thats where the cool wind comes from. If that doesnt work I have a 12000 BTC portable AC unit ready to go. Would rather not use it though.

That portable AC unit won't do anything in your garage. Once your garage's ambient temperature starts to increase well into the 80's and lower 90's there isn't much you can do. And since most garage's aren't insulated (why would they be) they are hard to cool and hard to keep warm. They aren't designed to be. Notice no videos with these powered on? There's really no where you can put one in any house and not hear it.

ehhh thats why they have BTU rating. Its meant to cool ambient air.

12000btu is plenty for 1.5kw. However if you have multiple SP10s.... you will have a problem.
