My Ampro 3300, which is ceiling mounted, has two fans mounted at the top, which pulls fresh air DOWN into the unit directly above the CRT yoke assemblies, where I presume the heat inside the PJ is forced out the front of the unit around the CRT's.
When the PJ is table top mounted, those same fans pull fresh air UP from the bottom.
Does anyone else think that the Ampro's ventilation scheme, using fans to push fresh air down (while heat rises) seems flawed for a projector in a ceiling mounted assembly? (FWIW, it appears to me that many projectors, especially modern LCD\\DLP's, are not optimally designed for cooling in a ceiling mounted configuration).
I am considering adding a third fan mounted on the top (bottom if table mounted) roughly above and slighty forward from the Spellman HVPS, and behind the CRT neck cards. This fan would rotate in the opposite direction, and would pull the heat UP and out. It looks like there is plenty of room in the case to do this.
I think this would help cool the inside cavity more efficiently.
Does anyone see any potential problems with this idea? Am I overlooking some important engineering concept that messing with the stock cooling architecture would harm?
I'd appreciate any thoughts or comments.
