🌡️ Redid the thermal paste on my laptop, did it actually make a real difference for you?

My laptop has been running noticeably hotter than usual for the past several months, fan constantly spinning at a fairly high, noticeable speed even during genuinely light everyday tasks like just browsing or writing a document, nothing especially demanding that should reasonably justify that specific level of consistent fan noise and heat output throughout the day. Read that reapplying thermal paste can genuinely help significantly once the original factory application has dried out or degraded naturally over several years of regular use, which apparently is a fairly normal and expected part of any laptop's natural lifecycle over time regardless of how carefully it has actually been used and maintained otherwise. Decided to actually attempt it myself this past weekend rather than paying a shop for what sounded like a fairly straightforward task if approached carefully enough. The actual process itself was more nerve wracking than genuinely difficult in practice, mostly just being extremely careful removing screws in the correct specific order and keeping proper track of exactly which one went where during the whole careful disassembly process itself. Watched two different video guides beforehand just to be reasonably confident about the exact correct amount of paste to actually apply, since apparently using too much can genuinely be just as problematic as using too little in terms of actual heat transfer efficiency. After reassembling everything again carefully and turning it back on nervously, the difference in temperature and general fan noise was honestly more noticeable than I actually expected going into this whole specific process, fan staying noticeably quieter now during those exact same everyday light tasks that used to trigger it constantly before this repaste. Definitely worth doing if your laptop is a few years old already and running consistently hot for no genuinely obvious specific reason otherwise, though I would say do proper research beforehand and go in with realistic patience for the whole careful disassembly and reassembly process itself rather than rushing through it. Has anyone else tried this themselves on their own laptop, and did you see a similarly noticeable real difference afterward, or was your own specific improvement more modest than what I actually experienced this time?

Did not notice much difference during light everyday tasks like yours after my own repaste, fan still ramped up occasionally even for simple browsing sessions. Only really showed real improvement for me under sustained heavier load like video editing sessions, so results might vary quite a bit from person to person depending on how bad the original factory paste condition really was beforehand.

Used way too much paste on my first attempt exactly like you are warning against here, ended up with some squeezing out the sides and had to redo the entire process a second time after cleaning everything off properly. Less genuinely is more with thermal paste application, a pea sized amount spread thin covers most standard laptop processors completely fine.

Went through the exact same nervous disassembly process on my own laptop last year, definitely more stressful keeping track of every single screw than the actual paste application itself turned out to be. Fan noise dropped noticeably within the first week of regular use afterward, wish I had done it a full year earlier instead of living with that constant noise unnecessarily.
