@Muhman, Hahahaha, well technically parts of this are used in pc's as well 😅
This is called "peltier"-cooling and i got this construction on amazon for about 40Euros, i had to install tubes from pump to cooler to reservoir and buy a temperture cooled power adapter (about 10 euro) and since then it's working well even tho its a bit goofy looking. Oh and i forgot about the diy cable twisting shit i can't really recommend it if you have 0 skill in electric. But i don't have 400 euro for a real cooler. I mean it's working well and as long as i don't worry too much it's okay haha 💀
