whereas, the air in your case is much more than 1 degree higher than ambient. So, by using the radiator fan as an exhaust, you:
1. get less flow (if it's pushing through the radiator).
2. Get higher water temps.
3. Probably get higher case temps as even a low flow 120mm fan should offer significant intake of cooler air.
