Well, you have to include the rest of my statement: "Adding fins increases heat transfer rate, so fins would INCREASE the temperature of the electronics if they were somehow cooler than the surrounding environment." I was being a little facetious, sorry.
Fins will cool the electronics if the fins are hotter than the air surrounding the fins, whether the air is "blowing" or still. Moving air will make the fins much more effective. My point was that, in steady state, the electronics will always run hotter than the environment around them, since they generate heat. How much hotter depends on the effectiveness of the heat sink.
ALL electronics generate heat, even sensors. How much depends on the specific device, and how hot a given box runs depends on the how much heat is generated and how effectively it is transferred out.
You really can't think of any electronic devices in the nose that generate substantial heat? Or any "actuator/controller related boxes" that would be located in the nose? I can think of several boxes that are sometimes located in that area that have fairly big power devices inside (including flap actuator controllers). Looks pretty busy on the Ferrari, for example!
I'm told Red Bull doesn't use the Datron sensor. I just looked through the 600+ high res photos I have of the 2009 Red Bull and couldn't find any sign of a laser ride height sensor inside the nose. I'd be interested to see any evidence you have to the contrary, as it would surprise a number of people
.
Here's a photo of the front bulkhead, don't see any sign of a laser ride height sensor.
