I add a second heat pipe to my laptop cooling system and get shocking temperature reduction on my i7 4700mq. Please excuse my excitement but with over 30°C headroom, watch as I push this Haswell mobile CPU to 3.2Ghz all 4 cores speed and it doesn't even break a sweat. The first half of the video is the DIY build. The second half is the results and benchmarks.

    Thank you for doing it in english. It is incredible how many will use english title but speak in anything other than that
  • @markcoetzer7576
    Congratulations, I know how frustrating it can be when your laptop keeps thermal throttling, well done.
  • @oplefirem
    This was really cool and something I have never thought of. Impressive results. Makes you wonder why it didn't have something like this when new. There was loads of space for two heat pipes
  • @motolaoshin
    This is so impressive, I could feel the excitement in your voice. Going to do the same for my overheating dell latitude.
  • @meta9125
    Great job man!! i was really glad to see someone do this and recently too!! Inspired me to try the same on my laptop
  • @conanbarbarian
    Great work. In 2019 I changed thermal paste and cleaned the fan of my then 8 year old w520. Paste was like dried clay. It was long overdue. It got temps and throttling down a lot. What I remember it had a separate heat pipe for the gpu as well. If people new why their once good laptops feels slower and slower they would get it cleaned and repasted.
  • I am impressed with your Mod and video. you are my hero , i wish every laptop was like this when we get it origionally with 2 pipes
  • Thank you for uploading this video, very informative,I myself do a lot of mods and I gotta say it feels good to see that there people who are actually doing this too
  • @mikem.s.1183
    Very, very well done. 👏 You've given us great ideas and directions. Fantastic work.
  • @nikefootbag
    Really good idea for a heatpipe mod and good adaptation to the constraints
  • I think you did a great job at minimum cost, very well done 🥇
  • @dantonjorge1010
    Greetings from Brazil!!! Very well done, I’m planning on doing that to my laptop!
  • Very nice job ! Instructive . Nice video . Tuto for heatsink and throttlestop . Working on it on my laptop . Thx !!!!!
  • @Blu0tuth0ninja
    I would like to point out that the new heat pipe being hotter means its not as effective as the other, because ita not transferring the heat to the fins. Its still seems to be working well, but if it were soldered, it would be as cool as the origin pipe.
  • Well done! Thanks for sharing this video and especialy for well explaining what you have done there!
  • @timm7524
    This and Part 1 are great videos. Nice idea and well thought through. Thanks for talking through your thoughts as you worked. I'm brainstorming ways to better cool mine. More so it runs cooler than faster, though both would be nice of course. Thanks again! This is food for thought.
  • @MrGulinak
    This is incredible and informative. Thanks and good job
  • @Felipejsf77
    Thank you for showing your experiment pal! I've got a samsung np350xaa with a i58350U and MX110 both with a single narrow cooper pipe and I'll put another one
