I borrowed an infrared gun from work to measure my inlet and outlet of the condenser. I got anywhere from 1-2 degree differance to 11 degree differance but mostly they were no more then 5-6 degree differances. No matter if the fans were on or off. I first thought that maybe the gun was not accurate but I compared it to a Ryobi one that I had bought to measure distance turns out its got an infrared feature. Sure enough there both +/- 2-3 degrees on either side. So after about 5 readings with each I can see a pattern. I read somewhere (dont know if its good info) that is supposed to be 20-40 degree differance between inlet and outlet temps. Is that correct info?
