Inspiron 7786 2-in-1, fan noise
Inspiron 7786 2-in-1
I have a Inspiron 7786 2-in-1 since 2019.
A few weeks ago it started to present fan noisy.
With the Speccy app I verified that CPU is reaching sometimes 77ºC, but normally it works between 45ºC to 50ºC, but what irritates me is the constantly noise of the fan.
In some videos on YouTube I saw that the thermal paste has to be changed and this abruptly reduces the working temperature and with that the fan is quieter.
Is this the case that I change the thermal paste?
The specs are:
-Operating System Windows 11 Home 64-bit
-CPU Intel Core i7 @ 1.80GHz
-RAM 32,0GB
-Graphics
Generic PnP Monitor (1920x1080@60Hz)
Intel UHD Graphics 620 (Dell)
2047MB NVIDIA GeForce MX150 (Dell) 46 °C
ForceWare version: 398.36
SLI Disabled
- Storage - 894GB Intel Optane+932GBHDD (RAID (SSD))

Nearly 4 years in operation, your system may have accumulation of dust, restricting the air flow and in combination with a worn out fan, hence the constant noisy fan.
Get a can of compressed air and a soft brush to clean out the system first. If it can not improve the cooling as before, then you can proceed with the invasive thermal past change. Follow proper precaution steps while working on the system for a successful maintenance job.

Excessive fan noise in Dell computers can be caused by various factors. Here are some possible reasons and solutions to help address the issue:
1. Dust Accumulation: Over time, dust can accumulate inside the computer, particularly in the cooling system, which can cause the fans to work harder and create more noise. To resolve this, you can use compressed air or a vacuum cleaner to carefully clean the vents and fan blades. It's important to turn off the computer and disconnect the power source before cleaning.
2. High CPU/GPU Usage: If your computer is running resource-intensive tasks or applications, such as gaming or video editing, the CPU and GPU may generate more heat, causing the fans to spin faster and produce more noise. Consider closing unnecessary programs or reducing the workload to alleviate the strain on the system.
3. Outdated BIOS or Drivers: Ensure that your computer's BIOS firmware and device drivers are up to date. Dell periodically releases updates that can include performance optimizations and fan control enhancements. Visit Dell's official support website, enter your computer's model number, and download the latest BIOS and driver updates available for your specific model.
4. Inadequate Cooling or Ventilation: Insufficient airflow around the computer can lead to increased fan noise. Ensure that the computer is placed on a flat, stable surface and that the vents are not obstructed by objects. Additionally, consider using a cooling pad or an external fan to help with airflow and heat dissipation.
5. Faulty Fan: If none of the above solutions resolve the issue, it's possible that the fan itself is faulty or worn out. In such cases, it may be necessary to contact Dell technical support or a computer technician to diagnose the problem and replace the fan if needed.
Remember to exercise caution when cleaning or troubleshooting your computer's internal components. If you are uncertain or uncomfortable performing any of the steps, it's best to seek professional assistance to avoid causing further damage.
