I would not go there as a precautionary diversion.
Equip cooling isnt a precautionary diversion its an emergency.
Some highlights from the QRH
With Equipment Cooling selector in NORM or
STBY, one or more of these occur:
•Airflow is insufficient.
•An overheat is sensed.
•Smoke is sensed,
Avionics/electronic equipment and displays may
become unreliable or fail.
Plan to land at the nearest suitable airport.
