Yet again, everything works in testing but not in real world situations. I had the computer running in the trunk for 2 hrs with the temp staying at about 81F, which was about 5F above ambient at the time. I was about to leave for Nashville (about 4 hours from here) so I wanted to kinda make sure this was gonna work, thats why the 2 hour test with the car stationary.
I was all packed up, and went to go pick up my friend for the trip, and within 6 minutes the temperature had increased to 102F. I had to dismantle my false floor setup and unplug all the cables so I could hook everything up to my laptop. I left the carputer where it was in order to monitor temperatures.
With the fans on or off, the temperature rises rapidly (about 2F/minute) when the car is moving at any speed. I initially thought that this was due to the exhaust vent being so close to the muffler, but even after driving for an hour whenever the car comes to a stop the temperature begins to drop if I have the fans on.
on a side note, my laptop had ZERO problems with the heat. We even left it on in the trunk whilst we went to game 6 of the NHL playoffs in Nashville on saturday. The temperature in the trunk hit 143F, and when we got in the laptop had no problems at all.
