Sheesh, my 600 watt pumps way more heat than my 400 watt does. I've never worked with a 250 but I'm sure it will be minimal in comparison. I haven't checked the dimensions of the cab you're planning to put these items in, but do the math on cubic feet and I think you'll find that 110 per minute might be overkill. You may find yourself getting a fan speed controller or putting the thing on a periodic timer.
