Main Question or Discussion Point

Hello,
I'm working with a heat exchanger I'm trying to integrate into a cooling application. I've done some tests but want to have some clear understating of how the calculations are done or if I have missed something. Below is what I have so far.
So it's a radiation with 2 pwm fans, they push air through the radiator. It has a 1.7gpm water flow through the loop.

Air temp into fans: 30.1C
Air temp out fans (rear radiator): 59.2C
Input water temp to radiator: 64.8C
Output water temp from radiator:56.5C

So what I get from this is that the radiator is removing 8.3C from the water temp. How would this translate to actual power or BTUs dissipated by the radiator?
