A shop owner in Denver told me to stop cleaning every laptop fan and it cut my bench time way down
For 2 years I pulled every fan and scrubbed it with alcohol, even on quick tune-ups, because I thought it looked more professional. He told me most fans just need a blast of air and 2 drops of oil, and if the bearing is gone the client needs a new fan anyway, so pulling them was wasted time. Now I only deep clean when there's visible buildup or noise, and my tickets turn around faster, so what's the one step you all skip on a basic tune-up?
Funny thing is that same logic applies to thermal paste on machines that are only a year or two old. I used to scrape and repaste every single tune-up too and half the time the old paste was still soft and fine. Now I just check temps first and only crack it open if the numbers are actually bad, saves me a ton of time.
