Fanless and open-air chassis possible?

Green Mesh has an open-air PC and claims that it will be dust free. After reviewing the design, I do not understand how it is going to be so. Will the open chassis design enough to keep the system cool?

Dear David.D.eckr

It is work instead of relying on a fan to suck dust-laden air into the innards to cool the PC, the Green Mesh's openness causes a "chimney effect", due to the fact that hot air rises. This acts as a barrier against dust. That if the case is placed in sunlight, you can actually see dust specks being pushed away.

However with higher voltage power supply unit will not be able to use this method.  This generates a lot of heat. This will stuck with a 300W at the most. That doesn’t require much power. I thought the best thing is to use low voltage power supply unit to reduce the heat and that will work without a problem.

Best Regards,

The Green Mesh is actually not a computer. It is only a CPU case with an open-air design. It is a fanless CPU tower case which is made of mesh. Like with the usual fully enclosed PC case that has fan ports for proper ventilation or airflow, this Green Mesh tower case gets away with that with their open-air approach.

According to YoungYear Electronics, a Taiwanese manufacturer of power supply units, the open-air design of Green Mesh is actually the reason why dust will not magically accumulate inside the case. The Taiwanese manufacturer claims it will have three to four times less dust than a normal PC tower.

Instead of relying on a fan to suck dust-laden air to cool the PC, the openness of Green Mesh causes a “chimney effect” because of the fact that hot air rises. This serves as a barrier against dust. The downside of using Green Mesh is that you are stuck with a 300W power supply because higher voltage power supplies won’t be able to use this method.
