I meant that as part of circulating hot air and how well it would do with a year+ down the line. That plastic type cracks quite easily and if the fan vibrates, then it even becomes dangerous; specially in low humidity locations. That's why it strikes me as a weak point in the overall thingy.I'm not overly excited how the plastic looks either, but given how poorly plastic conducts electricity if your heatsink fan is getting very hot, you probably have a much bigger problem than a cheap fan!
