DELL Latitude 3520 laptop i5-1135G7 32GB 512GB SSD 15.6 FHD

Dell Latitude 3520 overview

The Dell Latitude 3520 is a 15.6 inch business laptop built around an Intel Core i5-1135G7 processor with four cores and a 4.2 GHz turbo frequency. It ships with 32 GB of memory and a 512 GB SSD running Windows 11 Pro. The non-touch FHD panel resolves at 1920 x 1080 and relies on integrated graphics for everyday productivity.

Thermals noise and power

The slim chassis measures 18.06 mm in height and weighs 1.79 kg, so the cooling solution is designed for typical office workloads rather than continuous heavy compute. Integrated graphics and a low base frequency of 0.9 GHz keep heat output modest during document editing, web browsing and video calls. Fan activity remains quiet under these conditions and power draw stays within the 4.5 mm barrel adapter rating.

Sustained load behaviour

Under prolonged multi-core tasks the processor will throttle from its 4.2 GHz peak to maintain thermal limits inside the compact 361 x 240.9 mm footprint. Expect reduced turbo duration and lower clock speeds once the system saturates its cooling capacity. Buyers who need consistent high-frequency performance for rendering or large data processing should consider a workstation-class machine with discrete graphics and larger thermal headroom.
