A Gateway 26" LCD monitor/TV is getting warm. I measure 115oF (45oC) with a
contact-type thermocouple sensor attached to a DMM.

I'v been considering adding a couple of small 12v box-type vent fans to get
rid of some of the heat from the active components in the back of the unit.

Should I be concerned? What temp is safe for such a display?

Thanks,

Probably not. Do you smell anything funky ... like burning insulation?

No.

It's not insulation toasting that I'm concerned about, but toasting those
things I can't smell (LED junctions, transistor junctions, etc.).

Do these displays have a range of safe operating temps, in general?

Yes, but I do not know what they are. If the temperature is unusual, based
on past experience, then there could be a problem.

If this is new equipment or a new environment, then you might be misled.

If you use a fan that is quiet enough to not disturb you but strong
enough to remove some of that heat it could make the TV last a lot
longer. Your best bet is to have the fan near a top vent drawing the
heat out.
Cooler air should be drawn in through lower vents.
Dust will also be drawn in and dst can trap heat - so it's a good idea
to use some compressed air to clean it out every few weeks.

mine runs abt 95 deg f

try running it at a slower refresh rate, say 60hz and see if a difference

most just use enough holes in the case to dissipate heat, check for dust
buildup or make more holes

is power source burning up? check the input power and see if it is within
the expected power consumption limits

room temperature will affect heat disssipation also,

even a moderate amount of air movement will make a difference around the
case, as the case is often a sink for internal heat/thermal paths
