While the Dell Inspiron 14 7400’s fan noise is impressive even at high workloads, the same couldn’t be said on its overall cooling systems. No matter the power mode, the Core i7 1165G7 always peaks at 100°c which results in throttling especially during long workloads. Fortunately, the Nvidia MX350 GPU keeps a steady 70°c regardless of workload.
