Reddit mentions of Cool Attic CX1500 Gable Mount Power Attic Ventilator with 2.6-Amp 60-Hz Motor and 14-Inch Blade

Not pictured, some weather stripping foam under the plywood in hopes of damping some vibration. Also I forgot to take pictures of wiring into the outlet in the crawl space.

The fan is a CX1500 "Cool Attic Power Gable Ventilator Fan"

The tools/materials I ended up needing:

• 1 10mm wrench
  
• 1 11mm wrench (Used for mounting the brackets)
  
• Drill
  
• Jigsaw
  
• Screws
  
• Hammer
  
• Nails
  
• Sealant (since its not an automatically closing one I sprayed some sealant on the wood to protect it)
  
• SOG Multi Tool
  
• The fan itself
  
• 24" square 3/8ths plywood (could have been a bit more in the vertical really)
  
• Wire to tie into the home power supply.
  
• Wire nuts.
  
• Weather stipping, self adhesive.
  
  I prepared the plywood first using the fan to draw a guide for the jigsaw. Drilled out a starter hole and followed the line with the saw. Also learned that I am bad at following lines.
  
  I had the 2x4 cut into 2' sections at Lowe's to save me some effort.
  
  Up in the crawl space/attic I nailed the 2x4 sections up, nothing special there and sprayed some sealant I had around. I also filled in some gaps in the gable vent (not pictured) with some foam backer rod I had extra of.
  
  Next went up the plywood with the cutout, I attached that with screws using the drill, much easier than swinging a hammer around up there. In hindsight, I should have picked up some longer screws and done the 2x4s with that too.
  
  Brought up the fan, mounted the brackets and mounted it to the plywood with screws. Had to bend it back a bit and adjust because there isn't a terribly large amount of clearance between the blades and the mounting bolts. If you buy one of these take note of that.
  
  I screwed the thermostat box to the brace in the path of the fan, wired in one end of the electrical cable following the instructions in the box - very straight forward. The load on the fan is fairly low, you can get away with 14-2.
  
  With everything else done, I killed the power and opened up the outlet up in the crawl space just across from the air conditioner blower. Didn't take any pictures of that, but basically just tied it into the black, white and ground wires from the house and closed up the outlet box. I removed the outlet to do it because I've never used it, nor have service techs. They just run an extension cord from in the house.
  
  Brought up the power and the fan worked. All in all if I take out the stop for breakfast, probably took me 2 hours. Hopefully it helps bring down the temps up there and make my summer bills a bit better.
  
  
  Edit - that thing I'm wearing in the picture is a Frogg Togg Chilly Dana, bandana. Really did help keep me cooler and acted as a sweatband.
