How to cool your projector
The best bang for buck projectors That right there, is one of the best projectors you can get on a budget.
The Benq W1070 / 1080ST or HT1075 in the US.
(The ST stands for Short Throw.)
My unit has one problem though, it over heats and shuts down.
I tried everything from cleaning the fans, changing the lamp unit and even leaving the cover off, but nothing worked.
