Choosing between 240mm and 360mm AIO liquid coolers depends on case space, cooling needs, budget, and noise preferences. Below is a focused comparison to highlight the key differences.

240mm AIO: Requires space for a 2-fan (120mm each) radiator. Fits most mid-tower, micro-ATX, and mini-ITX cases. Works well with large GPUs, as it avoids front-panel space conflicts.
360mm AIO: Needs room for a 3-fan radiator. Only fits mid-tower/full-tower cases (e.g., Corsair 4000D), often limited to front mounting (top spots may be too small). Risks crowding large GPUs in tight cases.
Key takeaway: If your case is small or you have a large GPU, 240mm is safer for fitment.
360mm AIO: Larger radiator = more surface area for heat dissipation. Lowers CPU temps by 3–5°C (vs. 240mm) under load, critical for overclocked CPUs (e.g., Core i9, Ryzen 9) or heavy tasks (video editing, gaming at 4K). Allows slower, quieter fan speeds while maintaining cooling.
240mm AIO: Adequate for mid-range CPUs (Core i5, Ryzen 5) and casual use. May need faster fans (louder) to match 360mm cooling in high-demand scenarios.
Key takeaway: For high-performance/overclocked builds, 360mm is better for temperature control.
240mm AIO: Typically \(30–\)50 cheaper than 360mm models (e.g., \(80–\)120 vs. \(120–\)180 for mid-tier brands). Saves money for users with basic cooling needs.
360mm AIO: Costs more upfront but justifies the price for power users. Occasional sales may narrow the gap, so check deals.
Key takeaway: For budget builds or casual use, 240mm offers better value.
Scenario | Best Choice | Why? |
Mid-range CPUs (i5/Ryzen 5), casual use | 240mm | Fits most cases, costs less, and cools adequately. |
High-end CPUs (i9/Ryzen 9), overclocking | 360mm | Handles heat better, keeps temps stable under load. |
Small cases (mini-ITX/micro-ATX) | 240mm | Guaranteed fit; 360mm will likely be too big. |
Quiet builds | 360mm | Larger radiator allows slower, quieter fans. |
Choose 240mm if: You have a small case, a mid-range CPU, or need to save money.
Choose 360mm if: You have a large case, a high-end/overclocked CPU, or prioritize quiet, powerful cooling.
Match the cooler to your build’s needs—there’s no "best" size, only the best fit for your PC.
