Need help mounting 6' exhaust fan inside GrowLab?

So I finally got everything that I will need to hook up my GrowLab, the only issue that I am having to finalize my tent is mounting my 6' exhaust fan inside of my GrowLab tent. I would prefer not mounting it outside the tent to the wall, has anyone done this before & if so what did you use the mount the fan inside the tent? I went to Home Depot today and bought some nylon bungee cords that have clips on both sides, I'm a bit confused on how to hook this up inside the tent. I am probably going to go back to Home Depot in a few minutes if anything else is suggested what I may need to mount the fan, I was thinking maybe find some hooks that I can screw into the fan instead of the mount. Any suggestions would be greatly appreciated, thanks in advance.

picture 1: This is where I would like to mount the fan to, Im going to use the polls at top of the tent to hold the fan.

picture 2: This is a picture of the mount that came with my GrowBright 6' fan.

picture 5: Inside of my GrowLab, my reflector hooked up to my GrowBright carbon filter.

I would suggest strapping it either to the support poles on the top, or the the vertical corner pole. Personally, I would mount the fan so the openings are horizontal, and use the fans bracket. Secure it with some sort of steel strapping around the bracket and the corner pole. Even zip ties if you can get the industrial thick ones.

im curious how loud that fan is?
