heat is exactly the main killer in this fixtures and cheap chineese LEDs , since this is going to be home made, why not simply have the fans coming on at the same time as the lights, avoid the installation of expensive sensors, little fans dont use alot of juice and prevents any heat build up from the start.

We were going to put the fans on a thermo switch, we could have the fans on all time. For the question of having the resistors left off the circuit. It is possible to run every LED in parallel, but, The LEDs have a voltage drop of 3.2-3.8v you must have a resistor to control over voltage. We will run a series of 10-15 LEDs then those strands in parallel.

Scott here is some info I found, may help unless you already know it

my question is about the blue LEDs.... I have read about the new monitors that use LEDs/OLEDs. They have been discussing the blue ones in particular. Apparently the blue ones fry out wayyyy faster than the others, and the white ones turn yellow. I know that there's probably no inexpensive way to combat this, but maybe have the lights cycle? Meaning, sometimes you run two strips of white leds with two strips of blue, and then after a short while/the next day, you switch to 4 other strips. Example: rows 1234 on monday 5678 on tuesday 1234 on weds etc etc.
