A gaming laptop has to move the heat from a discrete graphics card and a high power processor out of a chassis about an inch thick, which is why gaming laptops are the loudest laptops most people will own. The makers know it, and several declare noise figures. None of them declares one while a game is running.
We cataloged 14 current US gaming laptops from Dell, Lenovo, ASUS and MSI that carry a maker noise declaration, out of dozens that do.
The declarations use test modes from the computer noise standards, and none of them is a game. Lenovo declares idle, disk access and a processor load mode, "Operating (CPU)". MSI's procedure idles the laptop, then runs Prime95, a processor stress test, and FurMark, a graphics stress test, but prints only one "Operation Mode" figure. Dell declares idle and disk access only for every Alienware. ASUS prints a single figure and names no mode.
So the Lenovo and MSI load figures are the closest thing to a working number, and even they understate a long gaming session, when the graphics card is the part working hardest.
Four conventions that do not mix
Dell prints a mean sound power, LWA,m, in bels, with a statistical adder, KV, of 0.4 in its own column. Lenovo prints an upper limit, LWA,c, with the adder already included, plus the sound pressure at the operator position. ASUS prints "the declared A-weighted sound power level" in dB under an old ECMA-109 method. MSI prints its figures with the unit "Bels / dB", and values like 44.6 only make sense as dB.
None of these converts into another, so we rank within each maker. Our sound power vs sound pressure explainer covers bels and the adder.
Lenovo: the only load pairs
Lenovo is the only maker that declares both the sound power and the sound pressure at your seat with the processor working, which makes its range the most useful. At the operator position under CPU load, the Legion 7i Gen 10 declares 23.3 dB, the Legion Pro 5 Gen 10 AMD 24.4, the Legion 5i Gen 10 24.9, the Legion Pro 7i Gen 10 28.3, the Legion 7a Gen 11 31.5 and the LOQ 15IRX10 34.5.
Sound power ranks them differently. The Legion Pro 5 Gen 10 AMD declares "3" bels under load and the Legion 7a 3.2, both below the Legion 7i's 3.3. The 7a is the clearest case: low total sound power, but more of it reaches the operator position.
Check the machine type
Lenovo's paperwork holds the biggest trap. Its Legion Pro 5 16IAX10 declaration, for machine type 83F3, reads 3.1 bels and 25.0 dB under CPU load. The 16IAX10H declaration, for machine type 83LU, reads 5.9 bels and 48.1 dB, the highest load sound power we read from Lenovo. The Legion Pro 7 shows the same split between its 83F5 and 83F4 declarations. The machine type is the first four characters of Lenovo's part number; match it to the declaration before you buy.
Alienware: quiet at idle, silent on load
Dell's Alienware datasheets are consistent and complete for what they cover. The 16 Aurora, 16X Aurora and 16 Area-51 all declare 2.2 bels mean at idle, and the 18 Area-51 declares 3.3. Sound pressure separates them: 14.5 dB for the 16 Aurora, 14.4 or 14.6 dB for the 16X Aurora depending on the regulatory type, 22.1 for the 16 Area-51 and 33.4 for the 18. Dell declares no processor or graphics load mode, so how loud an Alienware gets in a game is not published.
ASUS and MSI
ASUS's single figures run from 24.1 dB for the Zephyrus G14 (2025) to 28.9 dB for the Core Ultra versions of the Strix G16 (2025), with no mode given. ASUS's newest 2026 models, including the Zephyrus G14 and G16, use a newer sheet format with no noise line at all. MSI's Stealth 16 AI declares Idle Mode 23.2 and Operation Mode 44.6, and the Vector 16 HX AI 27.5 and 48.8. Each document names its test configuration, which is not always what MSI sells in the US: the Stealth was tested with a Core Ultra 9 285H, while the $1,749 US model has a Core Ultra 7. Several of MSI's newest models, including the 2026 Stealth 16 AI+, had no declaration on MSI's ErP page when we checked.
Who publishes nothing
We found no noise declaration for current HP OMEN and Victus laptops, Razer Blade laptops or Acer Predator Helios laptops. None of this means those laptops are loud; it means they cannot be ranked.
We did not measure any of these laptops. Every figure is the maker's own, quoted as published, with the convention, mode and position it comes with.
