Up untill 2 days ago this tank has been a monster. It mainly serves as a desktop replacement and is stationary ~75% of the time on my desk. It started to shut off by iteself and refuse to power back on for roughly 3 minutes. It started to exhibit this behavior after I live booted a linux distro SBF an android phone (not syaing its related at all). It did this again once or twice since then, noticed the fans where kickin it fullspeed as well.

Just a few minutes ago I started up LoL and started a game. Poof.. shut off.

I took the back valence off to expose the heatsinks as well as the bottom cover to expose the underside to check for abnormalities. Fans looked atlittle dusted. I tured it back on leaving these areas exposed and noticed that this fan:

was making alittle chatter (possibly bad baring?) The other fan wasnt even on as far as I could tell.
