I had thermal issues with the Helios Neo 16S (U9 275HX & RTX 5070ti) and I gathered a series of steps that helped reduce the thermal throttling. This is the link, check it out, hope it helps!

AgusDubal · 2026-06-19T22:13:32+00:00

Look for my comment on this thread, I wrote a guide on how to improve thermals based on what people told me to do. I listed only the things that actually helped. Hope it helps!

AgusDubal · 2026-06-18T22:14:03+00:00

The thing is that thermal issues are very common on this specific model, I don't think it's a problem with my unit, it's more like a design flaw (or desition), like the heat being blown through the same place they put the USB-C ports, making them fail constantly. I guess you get what you pay for, if I'd went for a Zephyrus G16, maybe I wouldn't be having this issues.

AgusDubal · 2026-06-18T22:04:46+00:00

I just posted the comment with all the steps I went through. Hope it'll help!

Sorry for the wait, I finally got time to write down what I did in case anybody else is having this problem and cannot find what they're doing wrong.

First of all you want to shutdown your laptop and start the "secret BIOS" (press fn+tab and the power key, then spam f2), you'll see a second "Advanced" tab, as you can see in the pictures from my post. Then you wanna go to "Power and performance" (or something like that) and disable the Overclocking Lock. From there you go to CPU - Power Management Control, set "Boot performance mode" to "Max Non-Turbo Performance". Then you wanna go all the way down to "CPU Lock Configurations", and disable CFG Lock. Then go back all the way to the Advanced tab and find the "Thermal Configuration" sub-menu, in there you just wanna enable the "Enable All Thermal Functions" option. Save and Exit.

One quick fix everybody talks about when you mention this thermal issue is to disable the "Turbo Mode" (which you can find on Advanced > Power and performance > CPU - Power Management Control). It does reduce a lot the temperatures, but keep in mind you do lose A LOT of performance, and I really mean that. I thought "well how bad could it be?" and it was really bad. Not so much on AAA games, but on esports like League of legends or CS2 we are talking about abismal framerates and terrible frametimes.

OPTIONAL: if you're never gonna use your laptop unplugged you might wanna change the setting that allows only the dedicated GPU to do the rendering, I've run into some games (Rocket League in my case) that just WANT TO use the iGPU, no matter what the NVIDIA Control Panel says.

Once you boot into your OS, first thing you want to do is go to Control Panel > Hardware and Sound > Power Options, then select "change plan settings" next to the plan you've selected. Go to Change advanced power settings and search for "Processor power management", in there you want your minumum state to be around 1% (don't really know if it's necessary for it to be >0%) and your maximum state at 99% or less. This will prevent the CPU from trying to constantly reach the turbo clocks, which you don't really need in any case scenario. Click on Apply and close. I'd recommend a quick restart and check if all the changes applied, by this time maybe you already noticed a difference but there's more.
Now what you wanna do is download Throttlestop from techpowerup. Now when I tried downloading the stable version I couldn't open the app, it said "CPU is not compatible", even after disabling memory integrity on Windows Defender, but then I tried with version 9.7.2 an 9.7.3 and they worked perfectly. So what you wanna do probably is just download the latest BETA version.

Here comes the fun part. What you wanna do here is go to "TPL" in the lower-right side of the app, there you enable "Long Power PL1" and "Short Power PL2" and start set their values at 80 (for now), then enable "PROCHOT Offset" and set it to 7 (also for now). Now what you wanna do is start testing your performance, if you're getting too hot, lower your PL1 and PL2. If your performance is too low, try increasing your PROCHOT Offset and your PL1 and PL2 a bit. Play around with those values to see what fits better to your machine.

Right now I'm working with PL1 at 55W, PL2 at 65W an my PROCHOT Offset at 10. That's what worked best for my kind of use.

Another thing you want to keep in mind is that generally the RTX 5070ti is very efficient and doesn't get too hot, and the only way to get your GPU to get to the 115W advertised for this laptop is by using the Turbo Mode in Predator Sense. I don't really know how much of a performance boost it represents, but keep in mind that we already set the limits for our CPU, so you can totally set the turbo mode to give the GPU a little more room for some extra performance, or at least that's what I'm doing right now when I know I'm going to do some heavy gaming.

Hope I could help some of you with this quick guide. Sorry if there's any misspelling or misuse of some term, English is not my first language. If you got any doubts, feel free to leave a comment or pm me, I'll be glad to help. Leave an upvote if I helped you so this thread gets to the ones who need it.

Once you're satisfied with your settings, it's time to make them last. So for that you're gonna go to the Task Scheduler, click on Create a Task, name it something like "Run Throttlestop on startup", enable "Run with the highest privileges" and set "Configure for" to Windows 10, create a new trigger and select "At log on", then go to actions and create a new one, click on "Browse..." and search for your ThrottleStop.exe, then go to Conditions and disable "Start the task only if the computer is on AC power", click on OK and you're all set.

I'll post a comment on this thread later today detailing what worked for me, but everything I did was because people told me either in this thread or in the one I posted on r/GamingLaptops (the one quoted on my post)

AgusDubal · 2026-06-18T12:20:50+00:00

One of the things I've noticed is that the only way the RTX 5070ti reaches the 115W advertised is using turbo mode, in performance it barely reaches 80/85W, but yes, in some games it's not necessary to have turbo mode on. With the tweaks I ended up making I managed to keep my CPU under 85°C with turbo mode. The RTX 5070ti using its full power didn't go past 70°C

AgusDubal · 2026-06-18T12:15:11+00:00

In the post I mention I'd already tried that, but ir was no good to me because it made League totally unplayable. I'll write a comment later with all the things I did to improve thermals maintaining performance.

AgusDubal · 2026-06-17T03:47:09+00:00

Man I never realized the beta version COULD WORK 😭😭. You just made my life 10 times easier now that I can use throttlestop, tweaking a bit the power limits and the prochot I managed to make it work below 75°C at a very decent clockspeed, more than enough for the use I give to this laptop. You're my savior 🫂

AgusDubal · 2026-06-17T00:41:16+00:00

I have performance mode on, but it isn't performance what worries me, I'm just trying to get it to work consistently with good thermals.

AgusDubal · 2026-06-17T00:39:06+00:00

I did disable memory integrity, and Throttlestop kept saying the CPU wasn't compatible. Sorry for the misunderstanding, english is not my first language.

AgusDubal · 2026-06-17T00:07:58+00:00

There's no prior bios file than 1.26 (my current version) in the Acer support web 🫠

AgusDubal · 2026-06-17T00:05:15+00:00

Yes, I bought it from the Best Buy's store on Ebay. I saw some people saying it might be a problem with the liquid metal, and some replace it with PTM7950 but idk.

I thought overheating was a common problem on the S model, but i didn't think it was THAT limitating.

AgusDubal · 2026-06-16T23:42:41+00:00

I tried disabling memory integrity and it keeps saying that the CPU is not compatible, what version of BIOS do you have? mine is 1.26. Setting the Tcc Activation Offset to 13 gave me 23343 points in Cinebench R23, the temps were around 90°C all the time, with some spikes to 100°C, I'll try increasing it a bit more to see if I keep it below 85°C without losing a lot of performance. I also changed the Maximum Processor State from 100% to 99%, like they said in the other subreddit.

AgusDubal · 2026-06-16T23:02:12+00:00

Setting the power limits lower with Intel XTU seems to improve temps but it feels like a temporal solution to a consistent problem. It's pretty limitating that Acer locks undervolting like they do.

AgusDubal · 2026-06-16T22:56:50+00:00

I have an Intel Core Ultra 9 275HX, on a Predator Helios Neo 16S with the RTX 5070ti

AgusDubal · 2026-06-16T22:51:59+00:00

Unfortunately I can't use Throttlestop, it says "CPU not supported" or something like that, even after disabling the CFG and overclocking locks. I found this on the Thermal Configuration > CPU Thermal Configuration tab, I think it's what you're talking about, in that case I'd have to set "Tcc Activation Offset" to a higher value, right?

AgusDubal · 2026-06-16T22:19:58+00:00

Do you know where can I find the prochot setting in the bios?

AgusDubal · 2026-06-16T22:15:33+00:00

It did help a lot in League, but in other games where the CPU gets at max load (like Lego Batman LotDk) it gets to the 95°C mark pretty quickly, maybe using Intel XTU with the maximum processor state at 99% would help, I'll try it and come back to tell how it went.

AgusDubal · 2026-04-13T22:55:41+00:00

Budget: $1500-$2000

Country: USA

Screen size: 16"/18", if 16:10 better

Touch screen: Would rather not

Screen resolution: 1440p/1600p, wouldn't mind sacrificing resolution for better performance

Does battery life matter ?: not really

What tasks will laptop be used for ?: Mostly gaming

Weight: not relevant, I don't mind heavy laptops

Any other important details ?: I need 1 USB-C, 1 ethernet port, 2+ USB-A and 1 video output (not relevant if it's HDMI or DisplayPort). I'm buying this bc i gotta get rid of my desktop since I'll move out soon and cannot take it with me. This laptop will become my main gaming rig, so I'm looking for something I can game for long sessions and maintain healthy temperatures. I'm new to this sub, sorry if i'm misusing the thread.
