Yeah it is getting a bit hot in there. Fan is on. But the cold side comes around over the rocker cover and is getting the heat soak from there I think as its close to the exhaust manifold.
I have wrapped the coldside pipe with some heat reflecting tape and its dropped the temps a bit. Gonna wrap the hotside also and see how it works out.
Also put in a bendable heatshield between the hotside / coldside and the manifold.
Originally had the cooler fan set with a thermostat but thinking about running it constant now.
