This is with an ambient temp of ~15C at the time I did this.

How fast is the air coming out of the heat exchanger? The slower it comes out, the longer the air molecules have to transfer heat. Here is an idea: take a hairdryer and turn it to "cool", so it only blows ambient air, and then blow that air behind the fan, so the air is coming out much faster. Now repeat your measurements.
If that example won't work then slowly breath out against your hand and then breath in quickly and breath out forcefully. Notice the difference in temperature?
Again, I chimed in because there is a cost in time and money to reinvent the wheel chasing a problem that may not exist. Maybe the idea of saving time and money on something that may have no gains is wasted on some people in this thread, but I think it is worth mentioning for anyone considering or reconsidering their setup.
