You are absotulely correct, in a sense, but somewhat in error. The first part is very true-- in the sense of a space environment; however, following it up with the part about FAN cooling sort of gives it away, doesn't it?
To the best of my knowledge, the the RADIO aboard the ISS is located in a life-support (air) environment, and NOT in a vacuum of space.
Don't forget, for *convective* cooling, you need gravity. There is no consistent gravity vector aboard the ISS that will cause cold air to fall, and warm air to rise, sufficient for convective cooling.
There is a distinction between free convection and forced convection. Free convection requires gravity and doesnt work in microgravity while forced convection with a fan does. Both are types of convective heat transfer.
