Thermal pad thickness shouldn't be a company sercret by any means! It's basic of maintenance and when I call tech support it says something when even they can't tell me what size to use? Wtf are people to do when the laptop runs out of warranty? Send it back? Dang not that complicated to replace pads and grease! Expressing concern and frustrastion, not directing any of this towards board members sorry if I come off assholish.

Agree 100% and why is the service manual only available to the so called 'elite'
I remember the good old days when companies provided the schematics printed and included with the manual to everybody.

As much as I like this laptop, this will be my last from Acer.

Honestly, I ordered .5 , 1.0, 1.5, 2.0, and 3.0 mm thermal pads to hopefully cover this. Now beware that you do not stack thermal pads, it impacts thermal transfer and will make it run hotter. The pads I purchased have a higher rated thermal disepation and should help overall. After I measure and do a press check, I will let you know my findings.

dirtymotox well they arent even mentioned in any service manuals so its up to us the end user to find out

and i suspect all manufacturers expect the customers to still send it in after the warranty expires which wont be any cheap

of course no one does it

Just frustrating, kind of an important detail to get the correct size.

If a moderator asked an Acer engineer, they might be able to tell you the correct size of the thermal pads.

I'd appreciate the $^@& out of that. no one can help me so far, called support again and given a number for someone who might be able to help

Have you found anything new since you have gotten the pads?

dirtymotox · April 2020

Took it to a repair shop and had them do it since no technical data was available and I wasn't about to do a guessing game on my 2000$ laptop.

I have a PH315-52 (Helios 300 2019 edition) and I used 1mm pads on the GPU VRMs. I get a steady 80degC when gaming on auto fan speed.

@Pb101 Worked perfectly? Have the temperatures dropped?

Pb101 · April 2020

No real temp difference change. Thermal paste would be more important.

Hello everyone, I am trying to replace all the thermal pads and thermal paste in my laptop but I have one doubt.

Anyone knows what kind of thermal paste is the one in the picture marked in yellow?

I would like to know if I can replace it and if must be by thermal pads or thermal paste and in case of thermal paste if I can use the same as for the processor and graphic card.

Thanks in advance

hi there i i am also planing to change my thermal paste what do you do? do you replace the pink paste with thermal pads or thermal paste?

dirtymotox · May 2020

This isn't something a weekend PC enthusiast should. I mean that in a nice way. My new pads dropped the temps down I'd say about 10 but that's including nice thermal pads and paste. You don't. Put paste on pads btw.

I found another thread that someone put the thickness of the pads that they used for theirs and said it worked. I'll try mine as soon as I order the pads and give it a try myself. Here is the link to their page.

Scratch that. The 1mm pads caused higher gpu temps by poor heat sink contact.

I saw a recommendation for K5 Pro which is a paste equivalent for thermal pads (high viscous thermal paste). It is the equivalent (or prob better) for the pink paste on the vrm chips. It eliminates the guessing game of thermal pad size.

Awesome stuff. It dropped gpu temps nicely now that gpu has good contact with heat sink.

I would highly recommend.

Will the Arctic mx4 thermal past work on the vram ? I plan to repaste my acer heilios 300 2019 and I wonder if it will work

xapim · August 2020

Darking92 yes any thermal paste should work just fine on the vram chipsets for the 2019 variants even if its the rubbish cheapest on the older 2017/18 use thermal pads only u can also try the K5 pro mentioned above seems to work fine good luck

xapim · August 2020

Pb101 its great to know that the K5 pro works as intended so many ppl here asking for what they should apply to replace what was there on the 2019 models and above i also do not recommend thermal pads on these as if they applied the paste was for a reason if it was meant to be used with thermal pads they would had applied them as they did on the 2017/18 models
