Extra: The Return of the Stone Age

His grandma said, my new computer broke down after just a few months of use. The fan was as noisy as a tractor. I tried to use the knowledge I learned in my professional class to fix it, but there was no response from the afternoon until the evening. I had no choice but to unplug the fan directly.

My computer host weighs dozens of kilograms. It is a very heavy metal case. Moving it around is really strenuous work. To sum up, I was exhausted physically and mentally after repairing the computer for a day, so I took a day off. Alas, in fact, I really I really don’t want to ask for leave. After all, the third leave request form is really expensive. But unfortunately, I didn’t save the manuscript, and I couldn’t finish the coding in the remaining time...

Of course, other parts of the computer are actually fine. The main thing is the fan. When I turned it on this afternoon, it made an inexplicable noise like a tractor. It was obviously fine yesterday, and I don’t think there is anything wrong with the blades and bearings. It’s really I can't figure it out.

Regarding this fan, I just placed an order and bought a new one, and it was shipped by SF Express. I estimate that it should arrive in two or three days at most. Before that, I can only let the other fans go up first. One top.
