Why the CPU fan makes a huge noise after M.2 SSDs are installed on TVS-hx74 series?

(h474, h674, h874, h874t)
Recommendation
To improve heat dissipation, please attach a heatsink to the controller of the M.2 SSD, as it is the primary heat-generating component. Without proper cooling, the increased temperature of an M.2 PCIe NVMe SSD can cause the CPU fan to spin at higher speeds, potentially increasing overall system noise. Each TVS-hx74 NAS includes two small heatsinks. Please refer to the technical documentation of the M.2 SSD to locate the controller accurately.
Secondly, the chassis of the TVS-hx74 must be properly installed, as our cooling system is designed for an enclosed environment. Removing the chassis will disrupt the intended airflow, reducing cooling efficiency rather than improving it.
