Hi! I have the same laptop and I'm planning to replace the CPU thermal paste as well. I have a tube of used-but-sealed Noctua NT-H1 which is a 'gaming' thermal paste - will it work with the CPU of the E7470? And can I apply the Noctua thermal paste the same way that you did on your video or does the application method vary by different brands of paste? Thanks!
Yes Noctua NT-H1 is probably the best paste you could buy after thermal grizzly. I use it and prefer to spread as thinner layer as possible. The difference in application varies only buy prefernce and many do not spread it. In this video the guy has put a lot of paste on, some would say especially the first lot is waaay too much for its size. However in testing, using too much doesnt usually produce lower results. There are many videos where others have tested the different methods and amounts extensively, many are happy to just not spread at all. Its about 50/50 in terms of spreaders vs non spreaders but it isnt easy the first time. Your paste is easy to apply as long as you have alcohol to remove the excess.
I guess they are like Lenovo in that they think "Viel hilft viel!" (A lot helps a lot!) and use some of the shittiest nastiest Thermal paste (more like Thermal concrete). At work (I'm a beginner repair tech) we often joke that we should bill our cleaning of the fans and replacing the thermal as "performance improvement" (we do repairs for some big companies). For those interested in it, spread thermal paste as thinly as possible, on a desktop PC with Heatspreader you should be able to just about read the printing on it. Or rather be able to reconize it.
