Review on 💨 Enhanced CPU Cooling Fan Heatsink for Lenovo ThinkPad X1 Yoga X1 Carbon 4th Gen - 00JT800 01AW976 by Marley Woods

Googling Yoga fan problems yields MANY results. It looks like Lenovo didn't use the highest quality fans in some of their builds and this is now an issue for many users. Mine was 27 months old and decided to leave the country for Argentina. Finding the correct fan number wasn't easy, but Lenovo has a run tool on their website that finds the model and serial number of the device. After that I called Lenovo to get the fan number. I googled the part number and nbParts came up on Revain. When I returned to the US, the fan was already waiting for me. 10 screws to carefully remove the back cover and 4 more for the heatsink on the fan and I believe 2 more on the fan itself. (Don't forget to take the silver paste). I watched a youtube video on how to detach the PSU with tweezers (easy when flipped over to detach the cable). I removed the old one, wiped the base of the processor with some rubbing alcohol on a paper towel, added a drop of silver thermal paste, and pressed the new fan and heatsink into place. Replaced 4 screws (+2) and connected the cable. Snap the tiny lock into place and reattach the back cover. Power button pressed. Viola, good luck! Now for those unsure about doing this on my own, it was actually easy and watching YouTube videos gave me confidence. In Argentina, a fan made a whirring noise that got louder by the hour. Shutting down the laptop solved the problem but the whirlwind reboot came back and then the BIOS said: FAN ERROR and wouldn't boot. The solution is to enter the BIOS by pressing the key that takes you there (I think mine was DEL) and just press F10. & save up. I had to try a few times but it eventually booted. You must then immediately go to the POWER and/or BATTERY settings where the COOL setting is located. Mine was set to PASSIVE when on battery but ACTIVE when plugged in. I changed both modes to PASSIVE until I returned to the US. This allowed me to boot in any mode. After swapping the fan, I changed the setting back to ACTIVE when plugged in. It was easy, just make sure you have tweezers and the right size Phillips screwdriver.
