i run mine off a muchmore power supply, and i have never seen it get so cold that there's a build up of ice and i race in doors, ive tried to leave it on for 45 min and still no ice, it does get cold but nothing like the pics ive seen, ive also heard that if you change the aligator clips to banana plugs that helps, i did never saw a differance. I think all muchmore products are really good other than the motor cooler, but it does look cool!
