No worries. Happy to answer your questions. The fans are rated at 84 CFM each, so they push a lot of air. They are also really loud, so I don't recommend them unless you don't care about stealth. I used a 4" hole saw to mount them, which is a bigger hole than the fan. I sprayed expanding foam to close the gaps and permanently secure the fan.

Hey thanks for the comments. The fans failed because of the power supply but I can't explain why. It was as new as the fans and was working beautifully. The computer fans don't work so well with the backpressure of the carbon filter, so I have to run two in order to keep the cab cool with the filter in place. Good luck and let me know if you have any more ?'s.
