How could i cool off the heat coming off my hdtv?
Danny K asked:
I know hdtv’s run hot, but it winds up heating up my room by at least 7 degrees, and i have a 37″ hdtv in a small bedroom. Its great in the winter but in the summer it gets really hot, i put a 12″ fan on the back of it, but its the front screen that when i touch it, its extremely hot. Anyway of cooling it down?

Not without an air conditioner or similar.
A fan is good for moving heat around (and that’s good for not allowing heat to accumulate near the TV, and so heat it unnecessarily) , and by blowing air across your skin it makes you feel cooler, but it doesn’t get really get rid of heat.
If the TV uses, let’s say, 150 watts, then it is going to put out about as much heat as a 150 watt electric heater, or a 150 watt light bulb. Even the energy emitted as light (both by the TV and the light bulb) gets turned into heat when the light is absorbed elsewhere.
The only way to really get rid of the heat is with something like an air conditioner to “pump” the heat outside.
The cheaper alternative is to use a fan to bring cooler air in from someplace else and move the warmer air in the room out. But in summer it’s tough to find “cooler air from someplace else.”

Point a fan at where the TV is hot. The air will help wick away the excess heat.
Of course, that doesn’t really solve your problem in that the heat is still inside your room.
It’s odd that the screen is extremely hot. I’ve had tubes, plasmas and LCDs, and none of the screens ever got more then warm. Now my plasma does have a lot of heat coming out the top back where the vents are. It makes a nice extra heater for the room in the winter.
