When I got my LG Gram Pro 17 (2024, Intel Core Ultra 155H, RTX3050) the fans were extremely loud because the laptop was constantly overheating (and thermal throttling). Even putting the Fan on maximum level (in the LG Smart Assistant) didn't stop the overheating. Hence the fans made a lot of noise.

How to reduce noise levels on an LG Gram Pro 17 (2024)?

[update] Additional Info:

  • The laptop was new, no dust, no dirt. Just out of the original box.
  • The laptop was on an elevated arm with a metal board with holes in it where extra air can come through, about 20cm above the table. I also tested elevating the back part of the Laptop in the hopes that more air would help. It didn't.
  • Environmental temperatures were 25°C, air conditioned room
  • I extensively tested if it makes a difference using the integrated ARC GPU or the dedicated RTX3050. Both of them run at around 50-60°C maximum for normal Windows usage, while thermal throttling of the CPU starts at 104°C. I couldn't see any impact from using only one or the other GPU.

I had the same issue on a ThinkPad E14 running Windows 11.

I had the laptop on a stand which blocked the ventilation hole. Just moving the laptop slightly so it could blow air through a ventilation hole instead of on a metal sheet prevented fan noise substantially.

Only when I run demanding tasks for a couple of minutes does it take off.

If you can sacrifice performance for silence, you can change the Maximum Processor State; I changed it from 100% to 50%.

The temperature of my CPU (Intel Core Ultra 7 155U) dropped from 80°C to 55°C, the fan's noise level was greatly reduced from constant jet engine to unbearable.

The Core Max temperature dropped from 100°C to 61°C.

I gathered the temperatures from Fan Control. (One cannot control the fan curve via Fan Control; I tried that.)

You may want to set up different energy plans if you occasionally need the performance.

The quickest way is to use your search via

  • open start menu
  • type Edit Power Plan
  • Change advanced power settings
  • Expand Processor power management
  • Change the two values to something that works for you, e.g. 50%

One can also access the Edit Power Plan via:

Control Panel > Power Options

I have the 16" Gram (i7-1360P, 32GB, RTX3050), I just upgraded my video drivers and it is noticeably quieter now, both idle and when under load. Right now it's almost silent while idle, versus so load my GF made fun of me for it sounding like a jet engine.

Some months ago I purchased an LG Gram Pro 17 (2024, 32GB ram, RTX3050) and I almost send it back because of the loud fan noise due to high CPU temps. Fortunately I found ways to reduce the heat (and noise) and I'm now very happy with my new Laptop. It's really perfect for traveling. Not sure if I remember everything, but here are some ideas to get the noise level down.

  • For new Laptops: Let Windows do it's updates: Windows will want to do some bigger updates after setting up Windows for the first time. It may help to just give it the time to do so without actively using the laptop. Since the standard settings turn off the laptop pretty quickly if not actively used it's necessary to turn off some energy saving options for the "plugged in"-profile (System -> Power & Battery -> Screen, sleep & hibernate timeouts).

  • The quick fix: Use the laptop on battery: Power saving mechanisms will reduce system load, which leads to less heat, which requires less cooling. Especially Windows will stop some unnecessary background workload.

  • The fanless approach (not recommended): Turn off CPU-Boost and your Laptop won't overheat, and without excess heat the fans won't turn on. The downside: significantly less performance. But it will be good enough to surf a little bit, read, write, study or probably even watch a movie. And it will also use less battery, so you can use it longer without charging. Here's how you do it:

    • Win+R -> powercfg.cpl -> Change plan settings -> Change advanced power settings -> Processor Power Management -> Processor performance boost mode -> disable it here
    • If Processor performance boost mode isn't visible, you have to activate it in the registry: Win+R -> regedit -> find "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\54533251-82be-4824-96c1-47b60b740d00\be337238-0d82-4146-a960-4f3749d470c7" -> change Attributes to 1, if 1 doesn't do the trick try 2 instead (on my machine it only works with 2)

  • Reduce background load:

    • Generall approach:
      • Use Task manager (Ctrl+Shift+Esc) to observe which tasks permanently use the CPU. 2-3% can be already enough to (over)heat the CPU, if a task runs on a single P-Core. So if you see a task using CPU permanently go ask ChatGPT if it's needed and how to get rid of it. Two approaches to disable undesired background tasks are:
      • Disable automatic startup apps: Open Task manager (Ctrl+Shift+Esc) -> Startup apps -> Disable apps that you don't need
      • You can dig deeper to disable other services or check if a disabled startup app still remains as an automatic startup service: Win+R -> services.msc -> right click on a service -> properties -> set on manual or disabled.
    • "Microsoft streaming service proxy": A game changer for me was to find out that a microsoft office task was permanently overheating 1-2 P-Cores of the CPU, which led to permanent thermal throttling and constantly high Fan speeds. Even though I didn't install or use MS Office at all, and I definitely didn't use any freaking streaming service of microsoft. I disabled Office 365 in startup apps and the fan noise reduced significantly while plugged in, and was mostly gone when running the laptop on battery.
      • Open Task manager (Ctrl+Shift+Esc) -> Startup apps -> Disable all Microsoft Apps from starting automatically (Office might be enough though, but I'm not a fan of MS Bloatware anyways)
    • Windows defender: Since Windows defender often runs in the background and it wasn't possible to deactivate it with Win11 Home, I purchased a license for BitDefender. I am not sure if or how much of a difference it makes. My subjective opinion is that it was worth it - without guarantee :)

Before those changes the fans where constantly on max speed when connected to the power supply. Now even when connected to power supply it often turns off fans or keeps them at a low level (I have them on max speed in LG Smart Assistant). Except I put a lot of workload on the CPU of course. And when running on battery the fans are turned off 95% of the time. The silence is priceless :D

For me overall it's good enough like this to enjoy the laptop while still using some resource heavy programs. I hope this helps. I would have definitely been happy to know about this approaches right when I got my LG Gram 17 Pro (2024, with RTX3050). But hey, may it help someone else with an LG Gram Laptop :D

What I didn't figure out tho is the task "system" using a lot of CPU power. Not sure why the system/Win11 needs to randomly occupy some P-Cores of the CPU, but guess I can't just disable the kernel haha... Another cool insight: In the task manager, performance, CPU: right click -> change graph to -> logical processors. It gives insight to that even if the overall CPU usage is only at 20% some of the cores are running at 100%, which creates high temperatures, hence thermal throttling. For even more insights I used HWINFO. It allowed me to understand that often only 1-2 P-Cores are thermal throttling and not the whole CPU.
