Predator Helios 300 Thermal Pads

Triparadox

Lately I've been getting a pretty high temperature. I am thinking of repasting it and changing the pads. But I don't know what thickness I need to get. I am going to be buying all the necessary items from Amazon because the local Best Buy does not have any great thermal paste and does not sell the pads. I'm currently looking at 1 mm vs 1.5 mm. Also, I don't know how big the thermal pads I need. I don't know if 50 mm x 50 mm will be enough or not. In case it's not, I need to buy two from the beginning.

Hey mate,

same boat as you, also suspect heavy dust inside for some weird reason.

regarding pads, been looking around, best use 1.5mm allover. Will also see if i can pad the ssd somehow...

ill be using non-conductive Phobya NanoGrease paste, its the newest best stuff, works great with laptop (aham”warped”!) heatsinks, wont dry off and its non-conductive aka safe.

pads dont really matter but improvements can be made. Dont cover other extra components, pads dont transfer/dissipate well to plastic back or plain air.

tested several undervolts for CPu & GPU

cpu: TS with 3.4ghz at -145.5mV cache/core for gaming is best. Few games require 3.4Ghz+. Very consistent.

As well, -125 very stable for office/video edit, at 3.9ghz all cores. 

For bat, just off Turbo for extra video time.

GPU, issue is MSI Afterburn does NOt work well on laptops with nVidia Optimus or AMD equiv. UnderV brounght a 10% bench score increase with the Stable -125 on Cpu profile.
Voltage curve set to linear, keeps GpU cooler by 5 or even 10C in some games. Bench always push it to limit though.
It would be worth it....but:

issue is, in idle Windows or browsing, iGPU is denied access by Afterburn, so dGPU is always active to fx windows graphics and such, which heats up more then the intel graphics. Bottom line, better temps in games, higher temps in Idle/browse, also fans go up by 10-20%. unless one always closes Afterburn once done with gaming, theres no solution for afterburn & optimus/power save to be active together. 

Even opening Afterburn and not changing Anything, will increase temps.
Another way to simulate the temp effects is by 1. Turning off somehow the iGPU in your CPU or 2. By selecting the Nvidia GPU in nVidia Settings, not Auto. Same thing happens. Laptop goes full dedicated GPU. 
So maybe someone knows an alternative mV curve app, please..

thats about it. Its out there. Thats my saga with a gaming laptop. F me....:$) i miss my desktop

Yeah, there's a good chance it's caused by dust as well. I saw a guy on YouTube recording himself cleaning the laptop. It was only a 3-month gap between which and the dust accumulation was crazy. I'm going to clean it as well although I am not sure if I should spend $$$ on compressed air can just for that.

MSI Afterburner, for some reason, works pretty well for me. I followed the guide from Hotel Hero on YouTube and thermal decrease was legit with slight performance decrease if any. Also, please note that my model is the one that has i7-7700HQ. It cannot do 3.9 GHz.

Alright then, I'm just worried that 1.5 mm will not fit and is too large to let the CPU has as much contact with the heatsink as possible since this will cause major thermal problem and the paste will just be wasted.

Good night Triparadox !

What exact model of your laptop?
What temperatures are reaching?

@Triparadox changing the pads will not improve anything in your temps anyway only the thermal paste will the pads have no connection whatsoever with the cpu/gpu cooling/heatpipes and they should only be swapped if you damage them when disassembling it apart from that leave them as it is regarding the thermal paste i recommend kryonaut or similar

Um, I believe they have something to do with thermal, otherwise they won't be rated by W/mK. I know it's not as essential as changing the paste, but since I'm in it, I'm thinking of changing it anyway.

They only have to do with the chips in the mobo which they dont even heat up too much comparing with the cpu/gpu in fact i had seen someone that already tested that theory without thermal pads and the cpu/gpu temps wont get affected (only the internal mobo temps) it will not decrease your temps at all regarding cpu/gpu if thats your intention

Predator Helios 300 i7-7700HQ 1080p 60Hz display

With undervolting, I get 90 ish Celsius. Right now I deal with it by also underclocking it by 200 MHz and set the Speed Shift at ThrottleStop at 120.

I am going to change the paste as well, but I think since I'm at it, I'm thinking of doing that as well. The current pads are still those coming from factory.
