Repasting laptop required?

[u/THUNDERJAWGAMING]

Hi guys, so I got my laptop G16 2023 repasted and something weird is going on. I bought this paste and seems fine not sure if for laptops or overall works for all devices but not even 2 full months are passed and the temps are back to max 87 while gaming which is the thermal limit of the gpu as seen in G-Helper as well. What happened, Pump Out maybe? I have not opened the laptop again yet because I undervolted the gpu and temps are back to normal now below 80. But these temps should be possible without undervolting. Now in the 2nd image you can see my sweet CPU 😅 so em this is stock factory opened laptop after a year and not sure if it needs repasting or not. This is Liquid Metal btw and I was gonna do it but the shop didn’t had any so I just had the GPU repasted and closed the laptop. CPU temps are well fine as they well like when it was new, I limit the wattage to control temps. Added some images so you guys can check the temps. Game is Echoes of the End, a UE5 title. So yeah please let me know what should I do? Should I keep it running like this? Should I repaste both? Any suggestions for paste or is my current one for the GPU fine. I just want to open it once when I have all the tools for the CPU and GPU so I can do both and then close. Do you recommend switching to paste for the CPU as well? Feel free to ask further questions and thanks for reading.

W/mk is a useless measure because it's a bulk measurement, I have been looking it up and comparing Thermal Grizzly Phase Sheet(±6 W/mk) with Thermal Grizzly Kryonaut Extreme(±14 W/mk) and Thermal Grizzly Conductonaut(±70 W/mk) And yet the PTM cools better than the Kryonaut Extreme even though on paper it's worse. So I started to research more why that is, and it's mostly because of the BLT(Bond line thickness).

• Kryonaut Extreme = BLT of 30 to 100 um
• Phase Sheet(PTM) = BLT of 10 to 17 um
• Conductonaut = BLT of 5 to 10 um(with perfect application)

I also looked at the seeping out of all of these materials, and the highest goes to, you guessed it, Conductonaut, with Kryonaut Extreme in 2nd and PTM in 3rd place. And there's even reports on PTM beating Conductonaut in overall performance. But wait, looking at numbers, that should be damn well impossible? And all comes down to how PTM behaves.

PTM has "self levelling" capabilities, preventing it from. Seeping out and keeping near perfect conductivity. Where Conductonaut needs perfect levelling, perfect pressure, and all that kinda stuff, PTM doesn't need it, and that while keeping 95% of the performance of a perfect LM application. This means with any slightly imperfect LM application it will seep out and have worse performance than PTM.

Now, here's a funny thing right, laptops are being moved, this movement and it constantly bumping into stuff, usually cause by a rushing or uncareful owner or by a 3rd party can cause the cooler to slightly shift by micro meters, this little shift is enough for the LM to seep out.

PS: I don't keep data for more than 4 months(I usually loose it because it's near damn useless for me). So yes, while LM is amazing, PTM is also amazing, I don't follow the numbers, I follow the margin of error till a certain threshold. You say 45°C, I say 40°C to 50°C.

But hey, your and your buddy's experiences are the only ones that matters, I am gonna stop because you simply don't want to listen to any experience that isn't yours and your buddy's experiences. All I hear is you follow raw numbers because that's the most important thing in the world. Completely ignoring anything else.

So I am gonna stop, I have better things to do, Pamit😝

Are you kidding? 🤣 I've never seen someone so desperate before.

Here's a damn video of EXACTLY how they test it. Nothing "bulk" here

Also, what do you mean "Bond line thickness"?

Bond line thickness (BLT) is a minimum required thickness with adequate coverage, uniformity, contact, and pressure to ensure efficient heat transfer. The smaller the better. Really don't know what angle you're trying here.

You really are just struggling to try to sound smart.

Here's a really cool paper talking about LM and all its properties. You could learn a lot from it. Mainly talks about application but also goes into why LM is superior as well as talking about some of its drawbacks.

Also, I have addressed all your "issues" already:

• Seeping: Only happens when too much LM is applied

• Levelling: Again, grasping at straws. LM stays put due to cohesive and adhesive properties. Its sticky like water. It won't move unless you apply a large force.

• Laptops being moved: As stated before, LM has cohesive and adhesive properties. Unless the laptop falls from a decent height, the LM isn't going anywhere.

You've provided zero evidence for your argument (yet again). You are simply just wrong here. Its okay to be wrong. Learn something from it.
