Here is my assessment.
- Fan appears noisier than stock or I was just used to the noise the stock fan made.
- No issues cooling in 100 degree heat when empty and the A/C works just fine.
- Pulling a light trailer (about 2500 lbs) in 70 degree heat no problem.
- Pulling same trailer in 85 degree weather no problem and A/C works just fine.
- At idle there is enough air movement to suck a paper towel firmly on the A/C condenser.
Wish I could have pulled heavier, but that didn't happen. So I'll leave this one on till I have troubles, which at this point I'm not expecting.
