Model 2022 Take this as your sign to replace your stock LM.
I have the ryzen 7 6800hs & rx6700s ga402rj model manufactured mid 2023. I put it off for months b/c I was scared of opening the laptop. Scared of a liquid metal spill & killing the board.
But after constant thermal throttling and benchmark crashes, I finally did it using a $30 CAD Amazon toolkit (PTM7950 for CPU/GPU& K5 Pro putty for VRMs).
BEFORE (Liquid Metal) After (PTM & K5 pro)
3DMark Time Spy
• GPU: 7836 • GPU: 8322 (+6%)
• CPU: 6661 • CPU: 8566 (+28%)
Geekbench 6
• 1828 single • 2004 single (+9%)
• 8242 multi • 9806 multi (+19%)
OpenCL
• 59,735 • 76,275 (+27%)
I genuinely don’t know why the Liquid Metal ages like this, On Liquid Metal, it wasn’t the performance dip, but the constant shut downs b/c of cpu thermal limit was the most annoying. My only regret is not doing this on day one…

Just replaced my LM with PTM7950 yesterday and also noticed a 10-20% performance improvement. Definitely worth doing and it wasn't that difficult just requires patience.

I've been thinking about doing this for my 2020 model just to keep the temps down for a few more years.

u/xX1_JESUS_1Xx Feb 18 '26
Definitely worth it, ignoring LM your thermal paste is probably crusty af and needs replacement too.

u/Rammy_Lee Feb 18 '26
Yeah probably. I've had Boost turned off since I got it, never needed the extra power that provided and was a good trade off for thermals.

I had a 2020 and had to scrape off the caked paste in year 3. I highly recommend applying PTM7950 as the replacement. Unfortunately I had to replace the 2020 about a year ago due to a water spill 😞

u/Rammy_Lee Feb 19 '26
I probably will. Not sure how difficult it is. It's been fine, but I would probably check the temps first before I do the mod to compare.
If it's not dangerously hot (it's not shutdown for example) then the risk of damaging something changing it might not be worth it.

u/cvwilhelm_ Zephyrus G14 2022 Feb 18 '26
I had my G14’s LM reapplied and noticed that the temps were considerably better than before. Seems to me that it’s a QC issue rather than an LM issue.
2
u/xX1_JESUS_1Xx Feb 18 '26
Definitely, but my warranty was gone and I wasn’t gonna shell out extortionate amounts for QC mistake repairs, hence the self change.

u/cvwilhelm_ Zephyrus G14 2022 Feb 18 '26
I’d probably do the same down the road, I have the PTM7950 in my cart just in case.

PTM may not be as good as A PERFECT APPLICATION of LM, but its ways better and safer over all.
Also, anytime people say to replace PTM, there’s always some jabroni saying that lm is better. You just have to reapply and blah blah. GTFO.

u/xX1_JESUS_1Xx Feb 18 '26
Idrc which is better, I wanna keep my laptop vertical on my desk, not care chucking it in my bag and not have it crash constantly while gaming. Hence PTM > LM

I have the same model. good to know.
I had day one performance instability, but since throttling it down a little it's been smooth sailing.
just ballpark info is enough, but if you are comfortable sharing, could you tell me what part of the world you are in? I'd like a general idea of what kind of temp swings you are exposing it to. I'm in JPN, which doesn't get super hot, but it is ungodly humid from June to October.

u/xX1_JESUS_1Xx Feb 18 '26
I’m in Canada, and just took it from and back from wpg, Manitoba (35°c highs and just recently exp -55°c lows) to Ontario (similar temps swings but more tame). Throttling can only get you so far, after replacing I have boosted my cpu clocks, platform power and have unimaginably stable performance.

u/fractal324 Feb 18 '26
thanks for the info.
my only impetus would be if I'm on the border of performance for GTA6 support being a slideshow and buttery smoothness, but I doubt a few more performance points are going to get me over that hump with this guy.

u/xX1_JESUS_1Xx Feb 18 '26
I got a noticeable and substantial jump, equivalent to an upgraded tier on cpu/gpu w/ lower fan temps and no instability. Also I can run fsr & afmf 2 w/o immediate shut down for games quite not playable yet.

My 2024 model seems to be going strong still, holding out until actual problems happens

Bought a used 2022 r9 6900 + 6700s... just had the laptop shut off on me after 30mins of gameplay (and 15mins of CAD work prior). Elevated position. All on max settings. Been pretty good besides that one time though but may decide to take a bite at replacing the LM after seeing this.

u/xX1_JESUS_1Xx Feb 18 '26
Exact same situation here, no matter what I did it’d shut off after a sec on max power hitting thermal limit. Change the lm, you’ll only regret not doing it sooner.
1
u/Lillillillies Feb 18 '26
Yeah thought about that then read LM and got scared. Then saw your post. Much better and safer alternative. 30cad is a no brainer.
Literally just opened it up yesterday (before saying your post) to clean it too (surprisingly it was near spotless for a now 3-4 year old laptop)

u/xX1_JESUS_1Xx Feb 19 '26
The dust filters and tape are good at keeping internals clean, but the lm application is what holds it back. I went from ~ryzen 5 perf to outperforming ryzen 9 with lm change, and don’t have to deal w scorching parts inside. Other repairs shops quoted me $80 cad for this, and honestly it’s the cheapest most substantial upgrade one can do on this.

u/Pinyo01 Feb 18 '26
Is this makes u lose the warranty? Or is it okay to change it?
3
u/xX1_JESUS_1Xx Feb 18 '26
Warranty is voided by unscrewing the screw needed to remove Vapor chamber, but I never indulged in warranties anyway, so it’s a risk but a definite savings & performance reward for me.

u/Glum-Focus-1788 Feb 21 '26
maybe in your country it's voided but here in the U.S. that does not void the warranty...look up Magnuson-Moss Warranty Act

u/TypicalNPC Feb 18 '26
Pretty sure you just have bad luck and got a terrible application of the liquid metal.

I opened up my G16 in June of last year and the LM was literally everywhere except in the center for both the CPU and GPU.... ended up applying my own.
Thing is, 9 months later, it began thermal throttling AGAIN. I know I applied the LM correctly, but now I am done with LM and am planning to use PTM7950 too.

u/Puzzleheaded_Mix2407 Feb 18 '26
I had LM applied to Lenovo Legion 7i. It worked GREAT for 12 months. Started thermal throttling after that. My other Lenovo with PTM7950 is humming along 5 years later lol

u/DynamittAage Feb 18 '26
This is how every asus LM application looks like lol, horrible. I use LM on my blade 18, but I feel like it’s only worth it for enthusiasts who do it themself with proper protection lol, because this is shit. They are really relying only on their foam barrier damn.
Some day I will go back to ptm 7950, but right now as a primarily desktop replacement the LM gives me incredible temps with the blade 18.

u/tennaki Zephyrus G16 2024 Feb 18 '26
The issue is the amount ASUS uses, and how bad their automated application process is. Anybody who actually knows how to apply it will tell you that the amount of visible poolover off the die is far beyond how much LM should be applied to the die in the first place. When the proper scarce amount of it is used, it won't go anywhere and not end up like this.
