Both fans emmit a low rumbling noise.
Noise increases when set to 100%.
4 x SSD drives fitted. So not HD noise.
Are the fans required?
Can they be switched off?
If not, can they be replaced?

The fans are necessary as everything internal only has passive cooling on it, so the air flow is required to move it outwards.

The fans likely need to be re-lubricated if they are ball bearing based.

A TerraMaster representative will respond with instructions if the very latter is the situation.
