The rig isn't getting the full force of the vent as it spreads the heat out 180*, and I can't really move the PC from where it is now. The heat on does raise the temp about 2-3* though, but it doesn't run all the time. It's just enough to not be within margin of error, but nowhere near enough to bother me. I can lower the voltage and probably drop it a couple of degrees.....that's what I love about this setup, so much flexibility.
Actually, the vent does have a switch to adjust airflow, instead of deflection, I may be able to make a reduction! Thanks for getting the gears turnin....will see if it makes a difference. It doesn't need to be wide open anyway, I NEVER get cold in this part of the house.
