Helios 300, Re-pasted.. Thermal pad inquiry.

 Hi guys! I have a Helios 300 I just re-pasted and my god that thermal paste acer sends is god awful lol, but I noticed the thermal pads when putting it back on had some flakes of thermal paste on it (prolly when I was cleaning it they got on to it) I went to try and pick it off but it was not a good idea, I didn't directly touch the thermal pad I used a Q-tip and it just sorta well.. smeared a bit. I have 1.5mm and 1.0mm thermal pads.

1.5mm: https://www.amazon.com/gp/product/B00ZJSZ6WA/ref=oh_aui_detailpage_o08_s01?ie=UTF8&psc=1
1.0mm: https://www.amazon.com/gp/product/B00ZJSV8C2/ref=detailpage?ie=UTF8&psc=1

I have watched videos on youtube and been looking on forums but I can't find a definitive answer on which pads are 1.5 and which are 1.0. I tried to hold them up to each other but they both look the same like on the GPU memory chips, they are blue and holding up the 1.5 and 1mm thermal pads I got I couldn't really see a difference between the two and the yellowish looking ones was about the same situation. I watched the video here: https://www.youtube.com/watch?v=Ph2ibK79zd8 But I found the user here on the forums and he says it is a mix of 1.5 and 1.0mm pads and he is OCD like myself. So to sum it up, will it hurt if I use 1.5mm on everything? will it all fit alright still? I did everything in his video that he did to the letter and running prime95 I never broke 70c so I know I did good on the repaste and it is not undervolted. Or should I leave it be or will it cause damage with that sorta smeared flake on the thermal pad? Being OCD it is driving me insane a bit, however I rather be insane versus possibly breaking something.

    As I was cleaning off that thermal paste shown above, Some specs got onto the long rectangular thermal pad with the 4 indentations on it and the one above it.

    @Red-Sand
    I just want to say thank you for the video you made, While I had a lot of trouble it was because of you I finally got this helios 300 running right. I called acer trying to figure out what size 1/1.5mm pads went where and made it to level 2 and they couldn't give a response lol. They told me to take it to a local repair shop.. THe funny thing is I was standing in micro-center an authorized repair and service of acer at this time and they was clueless as well. So after 4 days a whole lot of thermal paste and testing pads I finally achieved this...

    I wanted to give a quick note to any that may be reading this, I had upgraded the stock ssd in it to a 960 512gb NVME but my PCH temps jumped to about 51c idle, I put back the stock hard drive and they idle at 35-41c now on PCH. I don't know if this has any serious relevance however this is just my findings! - Not undervolted. 
    P.S. -- the helios 300 won't turn on until all the screws are put back in lol...

    Hey so You applied the paste but ignored the thermal pad application ? So it did gave good results ?

    Forgive me for reviving an old thread, but I too would like to know where these 1.0 and 1.5mm pads of thermal grizzly minus pad 8 were used. I have an Acer Predator Helios 300 (2019 edition) and cannot for the life of me find an answer on what thickness of pad to use on the GPU VRM chips that surround the GPU die underneath the heatsink. Right now the VRM chips have an awfully dried out flaky pink thermpaste over them.. and that can't be good.

    For 2019 you can use 1.0 everywhere except video mems

    Need help with this guys. Recently re-pasted my Helios 300 2017 (G3-571) and i used 1.5mm on all the chips and MX4 to re-paste. CPU temps are fine but the GPU temps are much higher than they were before. ive tried all sorts of paste application methods/quantities but the result is the same. reaching 90 degrees on the GPU in certain games. Anyone had that kind of issue and can help me out?

    TheRealestPepito if your only having issues with your gpu temps its either a bad repaste or the pads are too thick i never replaced thermal pads on mine never had any issues they should only be replaced if they are either damaged or if you damage them while disassembling it also the spread method on repasting its always the best only a thin layer covering both diodes completely its enough too much its bad same as too less my temps dropped down 25+ after i optimized windows/undervolted/upgraded everything and repasted with kryonaut first week i got it and this was 2 years ago same temps today you cpu shouldnt go over 80/85 max and the cpu 70/75

    yea thats what im thinking, thanks. Gonna order some 0.5mm and 1.0mm pads to replace the current ones. 1.0 should be fine I think. Would be nice if the OP could let us know which parts he used 0.5 and which parts he used 1.0mm on when he solved his issue as well.

    I only used 1.0mm and 1.5mm, I forget the exact layout now on where I had them but I know it took a few days to get it perfect the temps on the laptop are still doing great to today! I do know that I also used thermal grizzly pads if that helps, and paste too after I finally got it right.. I went through a lot of paste... https://imgur.com/a/YyjI74q

    P.S. I know that when I was going through it I made it all the way to level 2 on the acer tech team and they had no idea about the exact layout. I replaced them because I got them dirty and well being OCD like I am I couldn't leave it like that.

    So turns out the pad i got from China was a 2.0mm instead of the ordered 1.5mm. I feel dumb now lol I ordered 0.5-1.0 and 1.5mm pads off ebay to replace it. Have to disable the gpu in the meantime. Thanks for the help guys.

    Hi @Rinji07 fisrt of all, congrats for this.

    I also have an Helios 300 and this week I`ll apply a new ones thermal pads from artic, and change the past, which is a CM Mastergel Maker and my temps in idle are 44c ~51c saddly, gaming this number go to hell and return bringing me something around 86c ~ 91c,  so I`ll change to Grizzly Carbonout  thermal pad. But, today I saw your post and lost my mind, because this are the temps of the dreams speaking of gaming on laptops.

    Could you share how you achived this results? or what products you have used? 

    Thank you.

    Sure, been a while but I went and dug up my amazon history lol.

    Temps are still the same to this day I have only re-opened it to do my bi yearly dusting in it and upgraded the stock SSD to a 512 SSD NON NVME. that pch gets a lil warm with an NVME in it and I just really am not that comfortable with it idling at like 60+ I like it near 40-45 idle and jumping to 55ish while gaming on it. However here is what I used personally.

    Pads 1.0mm --
    https://www.amazon.com/Thermal-Grizzly-Minus-Pad-120x20x1-0mm/dp/B00ZJSBRE6

    Pads 1.5mm --
    https://www.amazon.com/Thermal-Grizzly-Minus-High-Performance/dp/B00ZJSZ6WA

    Thermal Paste --

    https://www.amazon.com/ARCTIC-MX-4-2019-Performance-Durability/dp/B07LF66ZSV

    Can be any arctic mx 4, It is a great paste.

    As for the layout it took me a good while to get it just right and I honestly can't recall what went where for the pads. However if you place them wrong it isn't gonna break it but it will be warm if they are not making contact. Which is what happened to me and I simply had to just redo it. I think all in all it took me about 2 hours to get it perfect, and that was back when I didn't have a whole lot of experience with this particular laptop. It is a good machine however Acer really needs to upgrade there pads and paste I would gladly pay another 70-100 bucks for a quality job vs them just using colgate tooth paste lol.

    Thank u @Rinji07.

    I`ll get the thermal pads tomorrow, but I have to ask that, do u think its possible achieve the same results using only pads with 1.5mm? 

    Again, thank u for your feedback.

    When i repasted mine, from what i could tell, the thermal pads were 1.0mm on the GPU memory (the 6 chips around it) and the rest of the pads were 1.5mm.

    dantrius thats great :) but thats only valid for the 2017/18 H300 the 2019/20 the cooling system is completely different with separated fans and heatpipes they use thick thermal paste in most of the vram chipsets :)
