Applying Liquid Metal To PH317-55-71YX

sean6541

I have a Helios 300 that has temp issues. I want to try using liquid metal instead of thermal paste. I've used liquid metal before and will take all the precautions (conformal coating on the SMDs surrounding the CPU and GPU dies and foam dams to prevent any possible leakage). I understand that the liquid metal will have to be reapplied after a few weeks to a few months due to the gallium in liquid metal plating the copper. My question: is the part of the heatsink contacting the CPU and GPU actually copper? It looks like it, but I would just like to confirm.

Also, if anyone has used liquid metal on there Predator Helios laptops, feel free to share your results.

This is just my opinion “Liquid Metal Compounds” are very risky and should never be used with aluminium heat sinks for a start. The Helios 300 (don’t know which exact model you have?) all have copper heatsinks and tubing making up their thermal units and they have plenty of venting to keep it cool. There must be a reason that your CPU/GPU overheats? The main culprits are the fans that need changing.

I’ve never been a fan of these metal compounds as I’ve seen the damage that they cause to allot of laptops and desktops circuitries and mobos and how they spread and leak and damage them beyond repair as you can’t apply them like normal compounds as they leak if you do. If you want to take the risk then fine (hope your laptop is not under warranty as it will void it) as they do work but what is the price of damage and/or having to change this compound every few months which is a pain in comparison to analysing your laptops reason for overheating and putting a high grade paste. Below is an example of the Thermal Grizzly Conductonaut Ultra High Performance Liquid Metal Compound and as you can see that is a minimal amount as you have to put it on both surfaces and its so prone to leaking and making a mess of your mobo.

The laptop has always had thermal issues. Over the last few months I've tried everything I can think of including disassembling and cleaning the fans. I've repasted it numerous times but nothing makes any difference. It is out of warranty. It works fine, but gets very hot (92C, which is when throttling starts) compared to all other gaming laptops I've had which don't go above ~85C even when running benchmarks. The core temps are also quite uneven, ranging from 70-92C. Liquid metal is the only think left to try before I give up and just live with the temps.

Its up to you as LM is very risky and it has to be applied correctly and it also has to be repasted every few months as it dosent last, so if you do then get ready for allot more dismantling of your laptop.
