I just purchased an Ender 3 v2. I would like to swap out the fans for better dual bearing ones. The parts I am looking to order come as a kit with all 4 fans. But, only the power supply fan has the option of 12v or 24v. I do not want to crack open the ps until the fan starts making noise, due to voiding the warranty on a brand new unit. Is there another way to determine if the ps fan is 12/24v without being able to look at the sticker?
