If you're experiencing cooling issues with your PC and have an AIO (All-in-One) or Open Loop cooling system, it's crucial to check whether the pump is functioning properly. Here's a step-by-step guide to help you verify your pump's operation:

Why Should I Monitor My Cooler?

Monitoring your cooling pump is essential for maintaining optimal system performance and preventing overheating. Here's why it's important:

Prevent Overheating: Ensures your system stays within safe temperature limits, preventing potential damage to components.
Maintain Performance: Keeps your PC running smoothly without thermal throttling or shutdowns.
Diagnose Issues: Helps identify if the pump is the cause of cooling problems, allowing for timely repairs or replacements.

Identifying & Inspecting the Cooling System

Remove the Side Panel

Remove the glass side panel of your PC case. The method may vary depending on your chassis, but typically involves loosening thumb screws at the back or using thumb grooves.

AIO Systems

The pump is typically integrated with the CPU block and is often located directly on top of the CPU.
Check for any LED lights or indicators on the pump unit. Some pumps have LEDs that light up when powered.
Carefully reach into your PC case and gently touch the pump pipes. You should feel slight vibrations if the pump is running. This indicates that the pump is functioning correctly.
Listen closely for any humming or buzzing sounds, which can be another indication that the pump is operating.

Open Loop Systems

The pump is usually part of a combined reservoir/pump unit or may be a standalone component in the loop.
Look for signs of coolant movement, such as bubbles or the flow of liquid, which indicate the pump is working.
