So my SO got a USB powered mini-fridge that keeps a can of pop cool... We both were like... What the...

I took it apart and low and behold it's actually a small peltier cooler with a decent size 70x70mm heatsink on it with a fan.

I ran some quick tests and this is what I got. Stock the cold side gets down to 10c and 30c on the other warm side... Thats at 5v

I cut out the USB adapter and used a 7v charger I have.

The cold side is now down to 2c...lol! From what I can tell, it looks like the peltier is a 12v unit undervolted.

Here's my question... What could I use this for? All my pc components are cooled really well. Cpu stays under 70c, gpu under 40c. Is this just going to be a fun experiment device I might actually be able to make a real good mini-fridge after its running full volts or would I actually have some use for my pc?

I also swapped out the fan for a quiet 70mm fan. Lol

No use for the PC, but I would do something neat like integrate it into your desk

Yea good idea. I noticed after having it on awhile that it does crate a good amount of condensation due to the cold temperature...I'd rather not want to insulate against condensation if possible. Maybe turn it into a full power desk cooler...lol

I thought for a second about an extreme tablet SOC cooler but its just too massive and takes up wayy too much power to be worth it. lol

You could cool your favorite beer.

Maybe on a small water loop you can use it to chill your reservoir a pinch. You never know, may spare you a degree or two under heavy load
