On Sunday, thanks to a conspicuous burning smell, I determined that the power source fan on my computer had gone out. I panicked a bit because I was set to work from home today, but eventually I was able to jerry-rig a system that involved taking off the side of the tower and using an oscillating fan to keep things cool.
Then, just 45 minutes before I was set to start work, the replacement fan I had ordered from Gateway showed up at the door. Brilliant.
Not so much. I hadn't bothered to actually measure the fan that needed replacing, so the fan I ordered was too small.
