Well, the don't sweat but they do turn brown and start blinking.... maybe they are trying to make tears when they blink? So, is the answer no? I kinda figured that since google wasn't helping and that LEDS need to be kept relatively cool to survive...
I guess the idea way that fans could only cool the LEDs in a 75°C environment, if there was a liquid to evaporate, causing a cooling effect.
- Fans cool electronics by transporting as much cool air to the hot surfaces as possible. Then energy is transferred to the air and transported away. This works only if the air is cooler than the desired temperature of the device to be cooled.
- In addition fans also cool people by transporting as much dry air to the sweaty surfaces as possible. Then, sweat evaporates and take energy in form of enthalpy of vaporization with it. This works also when the air is hotter than the person to be cooled.
You do not have air that is cool enough to bring your LEDs to a healthy temperature, so you would need the second effect. So it is either moving them out, or (not really meant as a suggestion ...) mount them on a Peltier element.
