Laptop heatsink single to dual pipes upgrade mod. How to desolder & test laptop heat pipes. Part 1

DIY laptop heatsink mod. Time has come to upgrade my Lenovo g510 i7 4700mq cooling system to dual heat pipes. I'm hoping to have more temperature headroom to allow me to push all cores to 3Ghz. Currently, I can stress test my CPU at 2.6GHZ on all 4 cores without overheating. With a max stable temp of 86-94C.
Obviously, I am not going to just buy a dual heatsink system and swap it in. But where is the fun in that? I'll be taking the more adventurous route instead. Modding mine by adding another Heatpipe (sourced from a cheap second-hand Fujitsu Siemens heatsink system) to upgrade it from single to a dual heat pipe system. See how I desolder and test the heat pipes before installation.

What I used in the video:
- Spare heat sink from a Fujitsu Esprimo laptop, bought used.
- Cheap 2-speed dual heat gun using the hotter setting to melt solder.
- Rosin-based liquid soldering flux
- K type thermocouple fo test heat pipe heat transfer.

That reddit user used a modified i7-4980hq to fit into a laptop socket afaik; its TDP is high, so the user modified their heatsink... cool stuff!

pretty interesting find didnt know heatsinks were just held together with solder

Thank you I saved 70 dollars. Now It works great again

Muchas gracias amigo, era lo que estaba buscando, una prueba de temperatura de los heat pipes pero con una prueba similar como la que tu hiciste, tenia ess duda, mi vieja laptop murio y pensé que era porque posiblemente el heat pipe se había dañado de alguna forma, pero viendo tu publicación veo que los heat pipes son casi indestructibles y que la transferencia de calor que hacen es instantánea con una eficiencia tal vez del 99.99% o por lo menos eso parece.

Thank you very much friend, it was what I was looking for, a temperature test of the heat pipes but with a similar test like the one you did, I had a doubt, my old laptop died and I thought it was because the heat pipe had possibly been damaged from Somehow, but seeing your post I see that heat pipes are almost indestructible and that the heat transfer they do is instantaneous with an efficiency of perhaps 99.99% or at least that seems.

Very cool, i want to know what glue you are using? Thanks

[mafeceng]

thank you for your efforts, i appreciate that

Watching this video makes me want to jump on ebay and buy some heatpipe setups like this, not sure about the price now but that's cheaper than you can buy raw heatpipe for by far.

Congratulations teacher...do you know about laptop temperature sensor in the board? The fan cooler do not funtion when the pentium heat and shutdown the laptop

Drilling massive hole to rear cover and installing low profile desktop watercooler is the best way my brotha. cooling pad that is also drilled so the laptop stays straight. no thermal compound so easy to remove cooler after gaming. Do a video about this you will be amazed. take 5v from usb to fan and pump.

Do you know if the fans vary in speed depending on the manufacturer? I have the l440 and I feel that it is slow.

Where can I get this tool fix the problem heatsink separation no good .Heatsink pipe has on my store but its good or not consider 50 % condition.

[Phantom-mkkp]

It wont explode, the first thing to happen would be the flat pipe returns to it's original round shape. taking the temp to 330 C is not high enough to over pressurise

[Bankotsu]

I'm gonna do this in the next few days!
I will tell you if it works!

How are the temps if you put cooling silicone pads with Copper plate behind CPU and on the back of GPU ? I have not seen many Cooling pad videoes testing a Mod with bigger sized Pads that cover more than small areas .

[shanesatanic]

Have you tried solder it with copper brazing or maybe tig or cold welding?

[michaellk]

I plan to do this on a T430 dual pipe fan to cool my i73632qm. Have you ever tried doing this to another fan?

[-tf-boforsho]

this would be great with a liquid metal replacement vs solder liquid metal you can replace with ease over solder and when the heat pipes become old and lose the thermal transfer from oc or what ever you can get new ones and replace them, you can also build your own cooler

[olivierplayer]

i dont understand why they use pipes, why not put fan directly on cpu ?

[kayburcky]

Crazy how you managed to desolder that heat pipe without it exploding

But now i'm curious: would it be possible to desolder/solder the Heatpipe with one end in a cup of water for example? That could reduce the risk of the Pipe exploding...
