OmniBook 3 16-inch touch laptop

The HP OmniBook 3 is a 16-inch touchscreen laptop built around an AMD Ryzen 5 40 processor with four cores and eight threads. It ships with 8 GB of DDR5 memory and a 1 TB NVMe SSD running Windows 11 Pro. The FHD+ IPS panel delivers a 1920 x 1200 resolution for office work, web browsing and light creative tasks.

Sustained load on Ryzen 5 40

The Ryzen 5 40 reaches up to 4.3 GHz across its four cores, paired with Radeon 610M integrated graphics for everyday multitasking. Under continuous workloads such as large spreadsheets or video playback, the 45 W power supply and 3-cell battery maintain operation without the thermal headroom of higher-wattage designs. Performance scales with the cooling capacity of the slim chassis rather than a discrete GPU.

Thermals noise and power in daily use

The 0.65-inch profile and 4.43 lb weight keep fan surfaces small, so airflow is modest during typical office use. Surface temperatures stay comfortable for lap use during document editing or streaming. Fan noise becomes audible only when the processor sustains higher clocks for extended periods, while the 45 W adapter limits peak power draw to that level.
