Why Nothing Else Qualifies
Windows ARM
All large-screen Windows on ARM devices (Surface Laptop 7, Galaxy Book4 Edge, etc.) utilize active cooling (fans).
Intel/AMD x86
No fanless large-screen options exist in current generations. Ultra-low wattage chips are relegated to 11"-13" frames.
Large Chromebooks (≥15")
Currently, no fanless Chromebooks with a 15"+ screen offer 16GB of RAM.
Recommendations
MacBook Air 15" M5
16GB RAM / 512GB Storage
$1,349
The undisputed king of fanless laptops. Incredible efficiency, high peak performance, and excellent battery life.
MacBook Air 15" M4
16GB RAM / 256GB Storage
$949–$1,019 (Refurb)
Provides the highest performance per dollar. Only slightly behind the M5 in sheer performance.
Lenovo Chromebook Plus 14"
16GB RAM
$799
A capable, entirely silent web-centric machine for those who prefer ChromeOS or need to spend under $800.
ThinkPad X1 Fold 16
16GB RAM
$1,499+
An interesting folding form factor, but suffers from severe thermal throttling and poor performance per dollar.
