Nothing that I can think of...One thing I've been doing a lot lately is putting on my headphones to play music, but I end up not playing anything so I just sit there like an idiot wearing headphones for no reason... :|
I stop every hour or so and feel the intake fans on my PC to see how much air they are sucking. My PC is overclocked like a mofo (CPU, RAM, Video Card) and I have dust filters on the intake fans that need cleaned at least once a season.
I don't like to power down my PC (current uptime is almost two months, I should probably check for OS updates (got that set to manual)) so I'm constantly checking the flow of the intakes. They change speed depending upon how hot the PC is running, so I'm always checking them as my activity levels change.
I know, it's become almost OCD, but I can't help it. If I feel one starting to get weak on the airflow I'll start planning for a dust-out. I hate opening my PC up because the way the fan cables connect to the motherboard, when I have to hook them back up when I close it up, I'm doing it blind, as the side of the case has to be half-way on for the cables to reach the power ports on the mobo. Those three-pronged boots are hard to put in without looking.:?
