My fan tends to run more than I think it should, yet its not excessively hot in the room, any ideas on this ?

Good suggestions from and — both point to the two broad failure modes: something telling the fan to run harder, and something physically forcing it to. The checklist below gives a compact, safe workflow to pin down which of the two it is, plus practical next steps.

Start with quick software checks: confirm whether Windows is driving the fan by looking for sustained CPU/GPU load (Task Manager or Resource Monitor). Then read sensor data (use a general tool such as HWiNFO or HWMonitor) to see core temps and reported fan RPMs. If temps are high, focus on cooling; if temps look normal but the fan is at full speed even before Windows loads, suspect a sensor/firmware or hardware fault and run the OEM pre-boot diagnostics (Dell’s one-time boot menu typically exposes a diagnostics option).

If diagnostics point to hardware, inspect the internals carefully after unplugging power and grounding yourself. Look for obstructing cables, loose shrouds, fan blade wobble or grinding (bearing wear), and poor heatsink contact. Older systems can also have degraded thermal paste or slightly unseated heatsinks; reseating the heatsink and replacing paste often helps. Cleaning out accumulated deposits and ensuring unobstructed airflow will usually help — use short bursts of low-pressure air or a soft brush and avoid forcing the fan to overspin.

Finally, check firmware and control: update BIOS/embedded-controller firmware from Dell, and review any BIOS fan-profile options (some systems offer "quiet/standard/performance" choices). Third-party fan-control utilities exist but may not work with Dell’s embedded controller. If the fan is noisy, physically damaged, or the controller is misbehaving after firmware updates, replacing the fan assembly is a low-cost, effective fix. If unsure at any stage, a shop or Dell support can run the same checks safely.

The fan is more concerned about the temp of the CPUs than your room [it does affect it, naturally]. Use your mb makers software to check the core temps, or just get Coretemp [dl the software] to do it. Reset the desired fan profile in BIOS if you deem the fan is too active, and the core temps are safe [if there is that option].

As gerbil said ,plus ,because they are so compact laptop heatsinc and fans get dusty fast,therefor overheat quickly causing the fan to run more often,a simple 10$ can of compressed air and blow out the fan and heatsinc
