Mine is out on a table with nothing near the vents (or around the system in general). The hard locks aren't an overheating/hardware things either, it seems to be software related. Just because you haven't had problems yet doesn't mean the rest of us are doing something stupid with our machines. :/I got my Wii U on Tuesday and have been playing New Super Mario Bros U, Sonic Racing Transformed, and ZombiU pretty constantly. Along with that I've watched a bit of Netflix and YouTube here and there.
I haven't had a single hard lock. Are you guys putting the system on bare carpet and/or resting your monitors on top of it? I Remember seeing a gaming set up thread a few years ago where people had actually set their small TVs on top of the Xbox 360 covering some of the vents. I imagine these same people were those who got the red lights and had no idea why.
Makes me wonder sometimes.
