duskw4lker Posted February 3, 2022 Share Posted February 3, 2022 I will skip the part about removing the bottom cover, but still I suggest using a guitar pick to dislodge the little clamps around the chassis. 1) Disconnect the battery cable and main power cable (under main power there's a fan screw top right position in green) 2) Disconnect the WiFi antennas so you can reach the fan screw underneath 3) Disconnect both fans, pull a little from each side of the connection, be gentle!!! 4) Unscrew the 4 fan screws (in green circles) 5) Unscrew the 6 heatsink screws (in purple circles), those are numbered for the reverse procedure, keep that in mind (some may say that it doesn't matter) 6) Start pulling upwards and GENTLY towards you (lower than 45 degrees, start from a low angle and work from there) from the GPU part of the heatsink. at the same time hold with your other hand from the right fan. the whole unit including fans will come out together. I've seen other heatsinks that as soon as you pull it the fans fall down like a sack of potatoes, not in this case. 7) remove factory/old paste as usual, isopropyl alcohol, cotton swabs, paper towel, microfiber cloth. 😎 Apply the new thermal paste. The GPU die is big as heck, this model has an RTX 2070, so I suggest using the X pattern with dots in each quadrant. The CPU, in this case I7-9750h, compared to the GPU is small so I suggest a simple line from side to side of the die. 9) Take this chance to blow any dust bunnies where the fans rest: The chassis in this model has a sort of deposit at the exhausts where the fans spit the crap that it collects. 10) to put back the heatsink start by placing the upper part (lower inclination than 45 degrees) of it where it sits at the exhausts and again GENTLY let it descend in its proper position, if you initially inserted the heatsink properly (the angle I mean), it will feel that it sits without resistance. 11) Screw back the 6 (purple circles) heatsink screws in the order that reads on the engraving, a few turns each screw in order. do not overtighten, it has to be firm but not to the point where you are exerting yourself, this is not an engine nor a carpentry project. 12) feel free to put back everything together, fan screws first, then cables, battery last, as always - you don't want to fry your mobo. Sadly I don't have pictures with the naked mobo because I was more concerned of doing this right on first try, but I hope this helps as reference. yes it worked first try, it's been 2 years since I repasted with Thermalright TFX and no problems so far. Also don't forget to undervolt your CPU (where is Unclewebb 😞 😞 😞 ???? ) Suggested tools: latex gloves, cotton swabs, paper towel, tweezers with ceramic tips, guitar picks, in general use SOFT tools, wood, plastic, etc, not metallic ones. oh and if you can ground yourself with those wrist thingies. Cheers. Ps: English is not my native language, so excuse any grammar mistakes or weird expressions. Link to comment Share on other sites More sharing options...
