I still can't find a reason to run a fan on an RX8 in a 6 lb SC truck..... even when temps outside hit a hot summer day (I'd say 40 degrees, but I'm from Canada, so I know to you guys, 40 degrees is COLD) my ESC still only ever showed 4 temp lights....

Sure, in 8th scale or Monster trucks, it's likely necessary, but for 4x4 SC, it's just something to break and add vibration....
