Shed is a great idea. With 3000cfm fan pulling from inside your house your home A/C would never keep up anyway and would run constantly, taking all your mining rewards. The size(mining are) isnt that important...getting the heat out quickly is. I hope to have my shed delivered in the next two weeks. I still have to get underground power over there but shouldnt be much of an issue. Im going with a 36" 5000cfm fan. I will be getting a 12x26 shed and dividing it off only to use a smaller portion for my mining room( approx 10x12 area). The rest will be storage. If you havent got yours situated by then maybe i will have more advice at that time. I think the shed is the proper way to go.
Definitely keep me posted, even just update your journey in this thread if you'd like!
Why did you choose a 5000cfm fan?
for 20-30 rigs with 6x cards each in a 12x12 how much fan am I going to need?
What's the best setup for the fan? blow through intake on right exhaust on left side, or intake vents on both left and right with 2 big attic exhaust fans in the middle? Just want to build the most efficient setup possible you know?
You will have to determine the total cubic feet of the space your trying to cool. So if your space is 10x12x8 = 960 cubic feet
If you get a 3000 CFM (cubic feet per minute) fan, it will take about 20 sec to displace that space with "new air".
You will also need to consider intake and exhaust, make sure you have adequate airflow.
You ever have a 18" box fan and cover the back of it with something? It kills the air flow. Samething could happen with your setup.
Ultimately what's the best plan for cooling two 1500-2000 cfm fans mounted on one side? on the ceiling? one on side one on the ceiling? Also how much sq ft in vent would I need to keep proper airflow? Sorry for all the questions this is just out of my realm!
