This forum is as good a place as any to ask about this topic.
I've started taking HPDE and for fun am recording sessions using TrackAddict, with my iphone mounted to the dash. Problem is when temps start to rise (doesn't need to be more than about 85 deg ambient), the phone shuts down from the hot sun on the windshield plus using GPS+Bluetooth+Camera+Charging at once. I get 5-10 min of footage from a 20 minute session.
So! I need either a case or other product I can strap on the phone that will act as a good enough heat sink to keep the phone from shutting down. I can cool it or rest it or both between sessions, just has to last ~ 30 minutes of high use. Including in 105 deg ambient. Even my gopro shuts down in that heat.
I'm not worried about phone mounts, I can work around whatever is available. But now that Fry's is gone all that's available are random Made in China bits on Amazon which is a big gamble.
I figured I'd ask the collective here if anyone has worked on cooling for an iPhone and what you tried, how well did it work. Would it work on a car dashboard?
