Default Discrete Ordinates Irradiation on Moving Reference Frame

Hi all, I am modelling a room with people sleeping and rotating fans. For the fans I am set them as moving frames and the airflow velocity is consistent with site observations. I am having trouble with incorporating heat transfer in my model. For the radiation model, I have put in the Discrete Ordinates method. However, I don't know why the DO irradiation on my fan blades in the moving frame is so high.
Also, I am not getting a large thermal plume from human bodies like I would expect. The humans are modelled as walls with a heat flux of 40W/m2.

Apologies as I am new to the forum have very little experience in heat transfer modelling. Appreciate the help.

Just found out how to attach attachments.
