First off powered cable vents are no longer allowed in many areas. Check code.

Second and the reason they arent allowed is they do nothing. They certainly dont pay for themselves with conditioned air savings. And often just pull cool air from conditioned space because of cracks and gaps and insufficient insulation.

If you insist on putting a gable fan in, I doubt much air will be pulled through the other 2 gable vents because roof vents/gaps etc and soffit vents/gaps.

The radiant heat from the roof on summer daywill over come any fan. Spending money on a powered system wont change the temp and will only pull in conditioned air.

Put in a compact ladder in the other section of attic while you're there
