The blinking light issue is caused by the capacitor going bad on the power supply unit. You can replace the cap and see if that fixes it, or you can also get a small LED power supply and just replace the entire thing wholesale.
Great video! I had the bearings conk out in the cheap fans on mine. Ripped it open and saw it had std PC fans. I wondered if anyone else had done this already and ready and kudos for you with the temp tests! Upgrading them with HQ silent fans is the way to go! Ordering some fans and have a project for next weekend! :)
it comes with a cigarette lighter to keep it plugged-in in your car. if your car supplies power to the outlet when it's off. (mine doesn't). or you could use the 5v USB plug and power it using a power bank. but yeah, I would. I don't see why not.
Thank you so much for this I really appreciate this video I just have one question though can you still power this fridge with the USB cable after upgrading the fan? The USB part is why I love my coolulli
