First of all is it safe to to apply it ? i was thinking of getting the Thermal Grizzly conductonaut which is galium based, i am not quite sure whats the materials in my heatsink ? is it compatible ? if not which thermal paste should i get, conductive or not conductive, i want the lowest temperatures possible while not destroying my pc and without having to keep changing the thermal paste every once in a while.
this is not for overclocking per say but more in order to keep the temps as low as possible and maybe in the case of very low temps, give the gpu a small boost.

Please Help me, thank you !

Liquid metal in a laptop is a slightly dangerous thing. My advice is to find some videos showing the application of liquid metal. You're going to have to put something over the parts of the chip that aren't the core. Some people use conformal coating, others use clear nail polish. The problem with liquid metal is that it is conductive, electrically. So an errant splash or putting too much on it to the point it leaks would be very bad.

The Helios has copper on the contact points, so it will be safe to apply Conductonaut to it.

I used Arctic Silver 5 on my Helios 300, and it makes things acceptable, but isn't in any way outstanding. A good application will last you a while. It isn't like engine oil where you have to change it every 3,000 miles. A good thermal paste with a good application should last at LEAST a year, if not much longer.

I don't overclock my CPU, but I did overclock the GPU up to stock desktop 1060 speeds. I have extremely minimal thermal throttling under heavy synthetic stress testing on my CPU (undervolting doesn't help), and no throttling on my GPU. For games, I run pretty reasonably coo and don't usually get any higher than 80C. I have no idea how much liquid metal would improve that.

If you want to go with liquid metal my only advice is to watch a video first, then take it slow. Also, come back and let me know how it went temp wise. I'm currently entertaining the idea of doing it myself.

"Only that Thermal Grizzly conductonaut, and other Liquid metal products, is gallium based and it WILL alloy with your copper heatsink, reducing heat dissipation over time, and you will need to apply it again, and again, replace broken alloy heatsing, and add it again, and again, and so on.... i would only recomend it under ihs as it does not alloy so fast with nickel plated copper on the ihs, or in applications where replacing the heatsing in 1 to 2 years is cheap and not a problem. Never in a laptop."

i read this somewhere is it true ?
i actually read that liquid metal doesn't dry up so i wont need to change it, this fact makes me doubt that authenticity of this comment i read on a website. However i still cant risk it
Are we sure that it wont alloy ?

What sort of coating that wont affect performance can i put ?

and btw undervolting to -120mv actually helped me when it came to performance

That is completely true, however, it happens pretty slowly. You're probably looking at a reapplication in about 6 to 9 months. When you do that you need to polish the copper using a very fine abrasive to remove the area that has reacted. If too much of the copper surface has been damaged you'll need to replace the whole cooling assembly, so you need to be careful there. Liquid metal will dry up, but it is a result of this reaction. The liquid metal itself won't dry, but the copper alloy it creates will, so you'll have to swap it out every once in a while.

Liquid metal on a laptop is problematic at times and high maintenance, but works so well that it might be worth it to you.

If you decide that liquid metal isn't for you, any high quality thermal paste will be sufficient. The stock thermal material is garbage. Barely better than toothpaste. It is also applied poorly. In my case they used way too much and the glob was off center on the CPU.

I can't tell you what is best for you, but anything you can do to increase cooling will help. In my opinion they cut corners on the cooling. I've seen other mods where people stripped the paint off the cooling plate and heat pipes to improve performance. So, you have options.

Well, I'm glad you've had luck with undervolting. My system started to get unstable at around -80mv and the temp change wasn't worth the instability, and honestly didn't change the temps at all. So I'm at stock on the CPU because somehow I lost the silicon lottery pretty hard.
