Hi,
I've been using this aio watercooler for nearly two years and I'm worried it might be failing, though I'm not entirely sure. The model is CM Seidon 120v v2. The pump is being monitored in the bios—it displays the RPM. Sometimes, when I power on the PC, I hear a loud trickling noise coming from the waterblock or pump area. Previously, it was functioning well with idle temperatures around 25°C and 56°C under load, but now it's 48°C at idle and 79-83°C under load. Is this pump giving up?

There is a lot of incorrect information in this discussion. AIO coolers usually come with a 5-year warranty or lifespan, allowing you to replace them if needed. Functioning properly for a few days ago and then experiencing different temperatures today doesn’t necessarily mean the pump is failing. This might be caused by other factors—such as an airlock from moving the case, or background tasks like antivirus scans or updates running on the CPU.

If you prefer not to rely on an AIO cooler, there are excellent air coolers available that perform better for a lower price. Using a liquid cooler doesn’t automatically make it superior; most AIOs don’t reach the performance of custom watercooling systems, but there are alternatives worth considering.

Yeah, they usually pass away after a few years. Just replace them with something new. The Corsair H110i is decent.

They pass away after many years.
Just replace them with a new one. The Corsair H110i works fine.
It doesn't fit in my Corsair Carbide Spec-01 case xD

It won't fit in my Corsair Carbide Spec-01 case, though.
You could just use an air cooler and avoid any issues later.

Just because you use a liquid cooler doesn’t guarantee it’s a high-quality one. Most AIOs don’t reach the performance of custom watercooling systems, and there’s a common misconception that any liquid is suitable.
