I just purchased one of the thermaltake cooling fans and I'm placing it in the left rear corner near the vent of my 722. I have the fan facing out to draw out the warm air, my question is should I keep the fan runnind 24/7 because in the morning when I feel the box it's warm even though the tv hasn't been on all night. Thanks.
Since the 722 is basically running all the time you would be best to let the fan run
all the time also. I've had a Thermaltake fan placed just as you discribed and it
keeps my 722 happy. I would adjust the speed of the fan at the highest speed
without being a noise problem for you.
