Well, I wasn’t happy with how hot the projector was running with the original modification. So the projector went under the ‘knife’ again.
I enlarged the opening in the back panel to give the new fan better air intake. I also drilled out some of the vent holes to allow more airflow out of the power supply area.
The enlarged holes really seemed to make a difference in terms of how much air was coming out of the power supply — I suspect this was a big help.
Watched Shanghai Knights and the internal temperature only manged to climb to 31C. It seemed to be holding steady at this point. On power down, the temperature did climb higher than it had in the past but only by a few degrees. (highest temp was 52C)
I’m going to have to watch it for a while and see if its stable. I’ll probably also see if I can get some data from the AVSForum on ‘safe’ temperatures — but I suspect this is a good trade-off. Nearly silent power supply for a few degrees. I’m certain the unit wasn’t operating within a few degrees of its maximum temperature so I’m pretty sure I’m safe.
