Is it recommended/necessary to cool the type of controllers that are designed for wuxga panels?

My guess is it's not necessary.
The reason: because I've yet to see an LCD monitor with anything more than passive cooling using vents for natural convection. The backlight in a monitor is the largest source of heat.
Of course, if the controller is subjected to temps higher than it would normally see in an LCD monitor or TV, then it certainly wouldn't be a bad idea to provide some sort of cooling across it. Either a small fan, or just heatsinks on the controller chips (or both). I would think a little 12v spare fan from a small processor blowing air across the thing would be sufficient.

It would be easier for me not to integrate the controller in the two main ventilation pads I'm going to realize. Let me, based on your reasoning, first assemble the controller separate from these ventilation pads and try natural convection using vents .

The best test is to put your finger on the larger IC-s. It it is hot, heat-sink it. You can buy small stick-on heat-sinks which will fit the IC perfectly. The controller I had and also my DVD player the Genesis chip was running hot and in the DVD player it stopped functioning after a year. Using the heat-sink solved the problem.

Thanks for the supplementary (is that english?)..

But what's an IC

Integrated Circuit. It's the big chips on the controller board.

Yeah, I have noticed this too. The voltage regulator, the toroidal coil, and the genesis chip gets too hot to put your finger on indefinitely.

Probably 5 seconds to become uncomfortable on the genesis. I was thinking heat sink too...

(I also mentioned this to bruce, who builds projectors for sale, that maybe there should be airflow over the controller.)

Oh, I forgot to mention that both G2A220s that I have do the same thing, so I think it's normal for the card, but after so many experiences of heat degradation in expensive hardware (ahemXBOX) I would sink the chips.

Of course my original thought that these are installed in monitors with no active or significant passive cooling doesn't address the fact that the manufacturers would prefer these not last for to many years. If they do, it's less sales for them.
So, maybe they really should have more cooling then they normally do, but don't have it for business reasons.

I have a heat sink on the genesis chip on my g2a130. also forced air cooling across the entire board. my first g2a130 stopped working (i think it got to hot).

Just ordered sinks for the chips on my G2A220.

The chip attachment area is 30mm or 1.2 inches square for genesis chip.

Get some thermal transfer adhesive.

Well ok, I will rethink my cooling design and create an airflow. Thanks for the suggestions!



That could be very true
