Most of the heat in a computer comes from the working components, not the PSU itself. Even an old PSU is typically 70% efficient in the range that matters. The situations where the PSU makes the most heat are the same as when the rest of the machine makes the most heat.
As long as the fan doesn't shut down entirely at room temperature (easy to test for), you should be fine. Even a gentle flow of air is many times better than pure convection, if it hasn't been designed specifically for convection. - Jonathan Morton -- -- ----- You received this message because you are a member of the Vintage Macs group.
