If you're a dyer and put electronics in a closet you need to keep them cool with a decent flow of air. That's what muffin fans are for. Good price, not too loud and seems very well made. If you don't want them running all the time (not a good idea), look for a "temperature controller" or "temperature controller" that turns them on and off based on the internal temperature of your case. They are not expensive and they keep the temperature in this box within the range you specify. There are many styles and prices, so take some time to find one that suits your needs. Don't forget to get a dust filter that fits over the fan because you're going to really need it.
