So I am wanting to add some PC fans to blow across the top of my tank or sump to help cool my tank, currently running close to 81 degrees. Tank is a 240 gallon tank and is 72x30x24. My question is how many fans can be wired together and powered from the 24VDC power supply available on th EB832 on an apex? How would I go about wiring them together? Lastly what would be some good fans to use that can be run quietly?
