It's amazing how fans can pull in different temp air from one to another. The side tanks alone can account for up to a 1 c swing between the outside fans and middle fan without a draft. With a draft from the wrong direction, even more.
Room ambeint temps is far from the air temp going into the rads.
Not putting down your testing, just though I'd mention it so you could check it out for yourself.
