My fear with these designs is that because the chassis is the heatsink, there is the issue of the continuous deformation (expansion and contraction) of the chassis body/heatsink, and you get mechanical stresses on the mobo that eventually cause internal vias to break. So yes, it may work fine for 12 months, but the overall lifespan of the product might be significantly shortened.
- djsumdog 10y agoAs long as there's enough distributional area (if it's only warm to the touch), there shouldn't be enough heat build up to cause it to wear faster, right?
- commentzorro 10y agoI've own and have built a number of these and not not seen this ever. The cases are much thicker and rigid than you'd expect. 5+ years for a few of them now.
