I just purchased a used maxstar 150stl and was testing it out and it overheated after running for about 2 minutes. I took it apart and found the fan was not working and tested on a 12v power supply and it was still not working. I've ordered a fan to replace that but I am just curious if anyone has run into this issue before. Nothing on the machine felt very warm so i'm not sure that replacing the fan will fix the issue. any info on if this is a common occurrence would be welcome

it has a 100% duty cycle running off 115 at 100a. I was running around 90a.

Thanks in advance!
