Over cooling a Norcold Refer
I have an 18 year old Norcld 682IM refer that did not come with cooling fans. It works fine at 85 degrees or less but struggles to maintain 40 degrees inside the refer on 90 plus days. After reading m...

During the summer I shot the cooling tubes with an IR gun and got about 120 deg F with 80 deg ambient. There must be an optimal range for the cooling tubes, was hoping someone would know.
Total speculation, but I know reasonable air flow from the top, exhausting provides good air flow/linear air flow and assists cooling.
I would be concerned that a fan from the bottom, particularly a high CFM one could create as much turbulence and help. Said another way, it could over-cool the boiler and create turbulence at the top where the condenser is.
