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.
⚠️ Important: Measure your case clearance before ordering. 360mm radiators need 400mm+ of mounting space.
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.
✅ Pro Tip: If choosing between 240mm thick or 360mm thin, go with 240mm thick for quieter operation.
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.
How We Test Budget Liquid Coolers?
Our testing methodology ensures fair comparison across all price points.
