So my far right fan on my hydroshift 360mm lcd aio has been ticking and i only just noticed last night. It’s a very noticeable sound as if something is hitting the fan but the cables are clear of being in the way of the fan. It’s way more noticeable and louder on lower rpms such as 600rpm and when i stopped the fan with my finger, the noise stopped. Idk what to do about it because whenever i wanna put my pc fans on silent this just ticks me off
