The PC is very small and is rather quiet despite what some users claim. The fan does run constantly, but is fairly quiet and not annoying. The machine did have a few instances of locking up after basic tasks and was a chore to reboot properly. I attributed this to running too many tasks for the processor/RAM. I ended up returning this as it is awful slow when using it just for web browsing. Opening more than 3-4 tabs in Edge or a Chrome based browser and the CPU usage spikes to high 90s% (ProcessHacker). Internet browsing, even with one or two open tabs takes a long time to load. I also noticed it runs rather hot to the touch. This is with it sitting on my desk, with plenty of circulation, nothing set on top and not placed in sunlight.
