If the fan stays loud at idle, the system repeatedly warns about overheating, or you hear grinding, squealing, ticking, or rattling, check workload and airflow first, then use only controls documented for your exact model.
Why a gaming mini PC gets hot or loud
Games can place sustained load on a compact system, and a fan may speed up as temperatures rise. ASUS includes Mini PCs in its guidance on overheating and fan issues. Intel likewise notes that high CPU use can cause excessive heat and make the system fan run at 100% (Intel’s fan-running-at-100% guidance).

Noise that persists when the PC is idle, or begins suddenly without a demanding workload, deserves a check. Possible causes include a resource-heavy process, blocked vents, dust, poor placement, or a fan obstruction or fault. The sound matters too: ordinary rushing air differs from grinding, squealing, ticking, knocking, or loud rattling.

Check what is making the fan work hard
Compare gaming with idle
Note whether the noise starts only during a demanding game or remains high after you close it. If the fan is suddenly running hard outside a demanding workload, open Task Manager and sort processes by CPU use. Close a process only if you recognize it and know it is safe to stop; investigate unfamiliar processes rather than ending them at random.

Check airflow and placement
Use your model’s manual or chassis markings to identify its intake and exhaust vents. Move the PC away from walls, fabric, papers, and other objects that cover openings. Set it on a firm, flat surface with space around the vents, in a well-ventilated area. ASUS gives 5–35°C (41–95°F) as an ambient operating range in its general troubleshooting guidance, but the manual for your exact mini PC takes precedence (ASUS overheating and fan troubleshooting).
Do not assume that advice for a laptop stand or cooling pad applies to a mini PC: the relevant vents and airflow path depend on the chassis.

Clean vents carefully
- Shut down and unplug the PC. Disconnect its power before cleaning.
- Clear external openings. Remove objects and visible dust around the intake and exhaust without pushing debris into the chassis.
- If using canned air, follow the manufacturer’s precautions. ASUS recommends a commercially available compressed-air can held at a distance and not inverted during use. It warns against powerful air compressors because excessive pressure can damage fan blades.
- Stop if cleaning requires opening the chassis. Check the device manual and warranty terms first. If dust is deep inside, or the manual does not permit user access, contact the manufacturer or an authorized repairer.
Intel’s advice to check for obstructions, clean radiators with compressed air, and inspect for physical damage is specific to Intel NUC products; it is not blanket permission to disassemble every mini PC (Intel NUC noisy-fan troubleshooting).
Try only documented fan or power modes
Some mini PCs provide power or fan modes in a BIOS or a manufacturer utility; the labels, controls, and available modes vary by model. If your manufacturer documents options for your exact system, change one supported setting at a time and compare noise, CPU/GPU temperatures, game performance, and any signs of throttling under the same game and conditions.

Intel recommends trying Balanced and Cool modes for the particular NUC over-temperature warning it documents (Intel NUC over-temperature guidance). ASUS’s Visual BIOS instructions describe Quiet, Balanced, and Cool examples for NUC generations 5–8; those names and steps are not universal (ASUS Visual BIOS cooling and fan controls). In ASUS’s documented examples, Cool prioritizes cooler operation and can be slightly louder. ASUS also warns that manual fan control does not override the selected duty cycle, leaving users responsible for avoiding overheating.
Do not set a fixed low fan speed or disable thermal protections as a shortcut to silence. A quieter mode may reduce performance or temperature headroom; judge the result by both noise and stable game performance, not by temperature alone.

Know when noise points to a fault
Grinding, squealing, ticking, knocking, and loud rattling are reasons to check for an obstruction or physical damage rather than treating the sound as normal airflow. If the fan is visibly damaged, does not run, or continues to make abnormal noise after external obstructions are cleared, contact manufacturer support or an authorized repairer. Do the same if over-temperature warnings persist after you restore clear airflow and return supported settings to their defaults. A replacement fan cannot be selected safely without the exact mini PC model and compatible part number.

What noise figures can—and cannot—tell you
GIGABYTE’s 2022 product material for the GB-BEi7-1260 BRIX lists 20 dB in standby and just under 40 dB at 100% CPU load (GIGABYTE GB-BEi7-1260 product page). These are manufacturer-published figures for that specific model, not independent test results or a benchmark for gaming mini PCs generally. There is no universal noise target or safe fan setting established across models by these figures.
