DIY dual heat pipe laptop mod. i7 4700MQ now 13C Cooler at 3.2Ghz all cores for 617 Cinebench R15

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.

Fellow DIYers modding their heatsinks

[MrLelopes]

Thank you for doing it in english. It is incredible how many will use english title but speak in anything other than that

[markcoetzer]

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

[Developer-online]

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

[meta]

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.

[reigggg]

You did the miracle with simple tools, amazing job.

[Blututhninja]

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.

24:10 "I didn't want the whole freaking sky above my head" 🤣🤣🤣 You need to post more videos with your amazing personality!

[motolaoshin]

This is so impressive, I could feel the excitement in your voice. Going to do the same for my overheating dell latitude.

[joalltaeuber]

Watched this a few times. Still amazes me the temp drop. I have a Razor Blade Pro 2014 that has dismal heatsinks on CPU side, which is a 4700HQ. GPU side doesnt break a sweat. Even overclocking it. CPU just ramps up like a jet engine under any load and hits 90s at 3.2GHZ usage when gaming. Will be trying your trick. Cheers.

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

[mezcal]

I want to give a big shout out, and thank you to you for your help. Our old Lenovo G510 was dead, and although we only wanted this older unit as a backup, following your tutorials: I upgraded the Ram from 6g to 16g, the old slow Seagate HD to the Crucial 480GB SSD, and the I5 processor to the I7 4700MQ, and installed Win10 Pro.
I was able to get the dual pipe heatsink off of eBay. My first install had the idle temps at 50c, so I modified the heatsink by clamping down the GPU heat pipe (our G510 doesn’t utilize a GPU cooler) to the CPU pipe area securely with the CPU pipe using thermal paste and thermal glue. PC runs screaming fast with idle temps on all 4 cores below 40C. Total mods cost in 2024 approximately $100 USD.

I would rather use some low melting point paste for that, and used some sandpaper to remove that insulating black painting, that would have been more efficient and durable

[nikefootbag]

Really good idea for a heatpipe mod and good adaptation to the constraints

[padgepadgham]

I think you did a great job at minimum cost, very well done 🥇

[congthanh]

Incredible job, my man! I'm green with envy when my i5 9300h is idling at 46 😂 bless you for your work and hope you are alive and well!

[DavittFinol]

Thank you for sharing this with us! Greetings from Venezuela!

This is way too awesome. Fantastic DIY solution.
