Installed a big exhaust fan in the mining room! Now its too cold!

The summer months are on the way, and my mining basement is getting insanely hot. I had a cheap box fan in the window prior to this, but it just did not have enough power to keep everything cool.

**Well into the summer I got even more rigs, and even this fan could not keep up with keeping the basement room cold. Time to brainstorm for more power!
