Not entirely sure. The fan won't revolve faster than 1799 RPM, so and appears stuck between 1719-1799 RPM. It used to go faster. I tried blowing out the vents w/ compressed air, and barely anything came out. No unusual noises either.
I tried taking the frame bottom completely off, but some screws won't budge and I don't want to risk stripping them if there's a safer way. It's a Lenovo Thinkpad E460, still on warranty for 18 more months.
I'm planning to call up customer service and find a licensed repair shop tomorrow - if they don't simply advise me how to do so without voiding the warranty. - Bech
