Over cooling a Norcold Refer

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.

. This was my thinking also turbulent air flow cools much better than laminar air flow that is why I put the fan at the bottom. 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.

As mentioned, “pressurizing” the rear cavity from the bottom can create all kinds of cooling issues, including dead spots thanks to the turbulence, that’s why it’s rare to find any electronic equipment, especially servers with air being forced IN without internal ducting. You don’t need a turbine, just move enough air to release the heat.
