Will be interesting to see results between the three to be honest
Honestly Agie if it wasn't for you we wouldn't have seen this design flaw. You are a day or 2 away from summer while up here in the northern hemisphere we're approaching winter. Furthermore you're in Perth which is always bloody hot eh?
As this dash cam was launched/released in the fall of 2023 (relative to the northern hemisphere) we would have not seen this problem until 2024. All we would have to worry up here is our cars being too cold that the screen would start ghosting while the inside of the car was bone cold.
To further compound the heating issue, the windshield is insanely hot in comparison to the inside. Although that doesn't contribute much it still doesn't help as there no way to have the unit engulfed in cool air.
Reminds me of the days of the Pentium 4 chip. Although I didn't overclock mine the stock Intel cooler for the P4 was good but not great. An aftermarket one was better - heh the one I had was a Vantec Aeroflow spinning a whopping 5600 rpm (the fan diameter was 75mm). Then of course you can then install case fans to get air moving from the front of the computer over the motherboard and exhausting out the back. If that didn't work you would remove the side panels and run it open air. If that wasn't enough you get a regular desktop fan aimed at the motherboard. Watercooling was extremely niche back then and there weren't any closed loop water coolers only open loop.
VIOFO you're going to have to do something here. You can:
A. Shorten or remove the heatsink and make side vents larger and place ventilation elsewhere.
B. Install a user replaceable fan inside the unit. User replaceable because when it fails or on the verge of failure the noise it will make will be intolerable.
C. Time to move on from the wedge shape. Start with the standard point and shoot digital camera style and then start trimming the fat. Keep the screen but have backlit soft keys. Or you can make the screen much smaller and drop the live view look and more like pictogram digital display like you find on a printer/photocopy machine.
D. Release a new firmware which takes into account thermal throttling. So instead of on --> overheat hard shutdown have on --> thermal throttling to allow limited functionality --> hard shut down
Agie question. Under what load was your camera under when it went into hard shutdown. I.E. Was it in parking mode or was it completely off? I'm assuming the overheating shutdown was done as you started your car.
