Y50-70 Cooling mod (it's working dude)

**** I added a short video that shows the temp differentiation*******
Guys, you know the problem
And i think i found a solution, at least it worked for me.
Here is the miracle;
? used thermal pad over the heat pipe of the cpu, and it worked nice, In sum; the pad transfers the heat to the cover(thanks to lenovo its metal), and cover spreads heat , and this lowers the actual temp of the cpu.
I put the pad on the red rectangle.

Because i couldnt find thicker pad, i bent 1mm one and used like this; if you can find a thicker one like; 4mm or 5mm it will transfer heat more efficiently.


Of course you have to do it longer

And after the installation; you can see a little part of the thermal pad under the cooling vent.


And here are the results;
Ambient temp is 27c and 10 mins of prime95 max heat test. Couldn't go over 86c

And the temps after 10mins of GTA V , all settings are at maximum as to my cpu and gpu.



And these test were made without a cooling pad. And there is no room for worrying, because thermal pads are non-conductive so it will never cause electrical short circuit.
So give it a try people, i hope it works for you too.

 

Over 5hundred visitors and none gave it a go?
At least im pretty well satified with the mod.

 

Way to get creative!

 

just remove the bottom panel

 

actually, increasing surface area of heat dissipation is better compared to just using more airflow

 

The reason is that I don't have a Lenovo!

Nice simple mod - and those are the best IMHO.

 

That's a pretty simple mod, I'll have to try this out, thanks!

 

I may have overdone it but who cares. I gave it a try and used the heatsinks (IHS) extracted from a dead PS3 . So far not so much of a difference in actual temperature ranges(perhaps a decreae of 4 -5 °C), but at least it gives it some heat inertia so that it takes longer to reach higher temperatures.
Thinking of replacing those pads with actual thicker aluminum pieces and see if it improves things.

 

Hi there,
if you use copper shims, it will transfer heat more efficiently.
And be sure you fasten those shims as they are electrically conductive materials.

 

I already replaced the thermal pad I had put on that aluminum heatsink above the CPU by an aluminum piece. Will take pics later on.
The piece is thick enough to be held on by the pressure of the case so no screws were needed. I will see about getting a solid copper sheet that is thick enough to be held out by pressure of the case (And thus maximum heat conductivity).
I am already getting lower temps,about an additional 4-5C.

 

Great mod! I like how something this simple really helped!

 

Hey Meo, I have a doubt about this process. Pls. help me, my lenovo is overheating.

These thermal pads were put in pressure/contact with the cover or you put some glue ?

 

Are you using cooling pad ?

 

Major issue is fan efficienty on this laptop. If u check fan and radiator theres big hole where all pressure go off this hole and no trought radiator. I fix it to sealing this hole by special foamgum for high temperatures and my temps go down by 20 celsius. When I will be at home I will made more photos of my not MOD but Fixing constuction problem of cooling on y50-70. Most of laptops have fans and radiators sealed by tape and what i see Lenovo made big construction mistake in this.

If you want more info message me, or ask there.

 

Just the thermal pad is enough, no need for glue or something. the pressure between the back cover and the cpu cooler is enough to hold the thermal pad.

 

not cooling pad, thermal pad.
They are safe to use, as they are not electrically conductive.

 

Odd to see that gap not covered with a plastic flap like in other brands. In your case what benefit did you get in going with a foam rather than a thermal tape to cover the gap? What was the total improvement in temp?

 

Oh ! That's nice, man. Can u send more photos please ? I'll do it tomorrow + initial MOD

 

One more thing: What exactly is 'special foamgum for high temperatures' ? Can u explain to more detailed or suggest another tool (like thermal tape) ?

 

You can use thermal pad for filling that gap too. Just cut a piece of pad equal to that gap and fill it with it.
Make sure that pad is thick enough to fill in the gap and not to fell on to the fan blades.

 

Bro try to apply tape there, close to imposible to seal it properly and still u will have gap where u lose pressure to radiator. U can use tap from downside and corners but where is that big hole u need use something like I use.

As you can read in my post was about 20 celsius. Before i have when browsing about 60+ celsius now 40-45. Ofc I replace thermal paste becaus factory one was like stone and paste is not for cooling but is for filling gaps between heatsing and chip.

@Victoriu : Im sorry I write I add photos but I dont have time to make cause alot of work. Today or tomorrow I will upload there.

@Meo: Thermal pad is good to but cost more and alot harder to fill in the gap. Still I think foam is better becaus when u press u make foam smaller and after few sec foam expand and fill gap rly good and i can be 100% shure its dont touch blade or change position.

 

In theory pressure loss should be negligible if the fins are clear of debris, as long as there's nothing to create extra turbulence in the airflow. Clevo just uses a piece of plastic for the same thing. It doesn't seal anything on their models.

 

Are you serious with ur knowledge of physic? Air always choise way without any resistance. Radiator have resistance and hole? 0 ... For me with replace thermal paste is -20 celsius. When u seal this hole all pressure whichone fan make go trought radiator.

So photos of my work :

And dont tell me this is not big HOLE .....SRSLY ? @Tanner@XoticPC something special for you:



This is Heigh of hole ... OMFG 3,5mm

This is Radiator height:



and what abouts fans? Ouu je 10mm



Still Only one place where you can use tape:


Final one:


Maximum what you can put for test on your PC , Furmark with IntelBurnTest.



So that my results.. On normal use and gaming temps go on cpu about max 70 celsius and Nvidia graphic 60 celsius.

 

Thanks for the additional pics. My comment was based on the original ones looking like the gaps just lead to the inside of the computer, which would build up enough pressure to no longer be the path of least resistance even when considering the radiator. It looks like it might go to other vents from the new images and is a lot bigger than it appeared in the original so I stand corrected.

 

Thx for additional pics, man. Can you send a picture of this 'special foamgum for high temperatures' ? Or whatever u used to seal this hole

 

You can see in on first picture where i unseal

 

What thermal pad thickness should I use for both tasks outlined by Vybramo and Mao? I'm trying to buy some thermal pad online and don't know whether to get the 3mm one or the 4mm one (there is no 3.5mm)

 

Meo it's a great idea, gonna check it on mine, maybe even I'll add more thermal pad along the heat pipes as long they don't go on vent. Also have some copper shims and if I'll get a good way to fix them to the aluminium case without damaging it I'll add some, have to take the cover first to check is it worth, just changed paste yesterday, used arctic silver. But still waiting for delivery of thermal pads. I know I'll have to repast it again but had gaming night with mate so wanted to something before playing gta online. It's already better after repasting and cleaning whole cooling system. For my surprise there wasn't so much dust inside the fans and radiator after 3 years of having it

 

Forgive me, but what is the specific name of and where did you procure this special foamgum for high temperatures? I'd like to try this out.

Unfortunately the demonstrative photos included in the OP are no longer hosted, so I can't attempt that mod.

 

Just use some Scotch 33 eletrical tape, or if you want something that is not plastic, aluminium tape used in HVAC ducts, both will do the job without a problem, and wont melt or become loose.
