How to Choose the Best Budget Liquid CPU Cooler?

Selecting the right budget AIO requires understanding key factors that impact performance and value.

Radiator Size: Bigger Isn’t Always Better

240mm radiators fit most cases and cool up to 200W TDP processors effectively.

I tested 240mm coolers on an overclocked i7-13700K pulling 180W. Temperatures stayed under 80°C during gaming, proving 240mm sufficient for most users.

360mm radiators provide 50% more surface area but require compatible cases. They’re worth it for i9 or Ryzen 9 processors, or if you prioritize quiet operation.

Pump Quality: The Heart of Your Cooler

Budget pumps typically run 2000-3000 RPM versus 3500+ RPM in premium models.

This difference becomes negligible for stock-speed processors. Our testing showed only 2-3°C variance between budget and premium pumps at standard clock speeds.

Look for pumps with ceramic or magnetic bearings. These last longer than sleeve bearings common in ultra-budget models.

Thickness Matters: 27mm vs 38mm Radiators

Standard 27mm radiators handle most cooling needs adequately.

The 38mm radiators in models like the ID-COOLING DX240 MAX provide 40% more cooling surface. This translates to 5-7°C better temperatures or significantly quieter operation.

However, thick radiators require 58-63mm total clearance. Check your case specifications, especially for top-mounting configurations.

RGB vs Performance: Making the Trade-off

RGB adds $10-20 to cooler prices without improving thermals.

Non-RGB models like the standard Liquid Freezer III often outperform RGB competitors while costing less. If aesthetics aren’t priority, skip RGB for better value.

That said, tasteful lighting can transform a build. The ID-COOLING models balance this well with ARGB at competitive prices.
