I'm having troubles locating decent 40mm*40mm 12V TECs. I have only found 80w plates in 12v AND 40mm. I was hoping to find something in the 150w+ range. The ones that I have found in the required size and wattage, have been 24V. And if that's not possible, does anyone know of a gpu pelt block that will take a 50mm*50mm TEC?
