Fanless point of sale terminals are making a dent in the traditional terminal marketplace. The idea of not having a fan inside the terminal sucking in greasy, dirty air has a lot of restaurant owners realizing a longer lifespan for their terminals.
The idea is a good one. Since restaurants are notorious for having grease floating in the air it only stands to reason that a computer with a fan bringing in cooler air to cool down the computer would also bring in this dirty air. The grease settles onto the computer boards, coating them with grease. Dust and dirt are also brought into the computer and also settle onto the boards. It doesn’t take long before this cycle of grease and dirt creates a coating across the entire insides of the computer. This blanket of grease and dirt raises the temperature of the computer chips and either burns them out or shortens their lifespan.
Fanless terminals eliminate the circulating of dirty air and should lengthen the life of the computer or at least reduce the problems with the unit. It is a little early to see if the results are what is expected.
What we do know for now is that there is less buildup inside the units. The real test will come in the 2nd and 3rd year after installation.
