Cooler Master i30 CPU Cooler
The Cooler Master i30 is a compact 92mm cooler designed for Intel sockets LGA 1150/1151/1155/1156. It features a quiet 22dBA fan and a slim heatsink that fits smaller cases without sacrificing cooling. Best for budget-minded builders who want a low-noise solution in a compact form factor. A potential limitation is reduced airflow compared with larger dual-fan designs, which may affect cooling in highly loaded systems.
Thermalright Peerless Assassin 120 SE
The Thermalright Peerless Assassin 120 SE uses six heat pipes and a dual 120mm PWM fan setup, delivering strong cooling for Intel LGA 1151 and other platform sockets. It’s well-suited for performance-oriented builds where cooling efficiency matters under load. The large dual-fan footprint may require adequate clearance in smaller cases, so verify case compatibility before purchase.
Thermaltake Gravity i2
The Thermaltake Gravity i2 supports Intel LGA 1200/1156/1155/1150/1151 with a low-profile 92mm design. It is optimized for low-power CPUs and quieter operation, making it a good choice for space-constrained builds where noise and clearance are key concerns. It may not be the best option for very high-TDP CPUs or overclocked setups requiring aggressive cooling.
Copper Core Aluminum Heatsink (LPLMOOM)
This Copper Core Aluminum Heatsink from LPLMOOM emphasizes a copper heat-conductive core with an aluminum shell, designed to fit Intel LGA 1200/1151/1150/1155/1156. It’s a straightforward upgrade with tool-free mounting, suitable for mainstream builds that require reliable cooling without complex installation. Choose this option if you want a simple, solid cooler upgrade and easy compatibility, but note that copper cores add weight and the overall profile should fit your case with RAM clearance in mind.
i3/i5/i7 CPU Cooler Aluminum Heatsink (LPLMOOM)
This LPLMOOM heatsink supports LGA 1200/1151/1150/1155/1156 with an included 8-inch PWM fan that auto-adjusts up to 3,000 RPM. It offers plug-and-play installation with pre-applied thermal paste for a quick upgrade. Best for beginners upgrading an older cooler who want a silent-to-mid-range performing fan. The main limitation is its generic design, which may not fit all cases or RAM configurations—verify clearance before buying.
Buying Guide
- Socket compatibility: Ensure the heatsink explicitly lists LGA 1151 support. Some products also support other sockets; verify the mounting hardware and backplate compatibility for your motherboard.
- Cooling performance vs. space: If you have a compact case, prefer low-profile or single-fan designs like the i30 or Gravity i2. For high-demand CPUs, consider dual-fan models such as the Peerless Assassin 120 SE.
- Noise and fan quality: Look at listed noise levels (dB) and fan speed (RPM). Quieter fans with sufficient RPM are ideal for living spaces or streaming setups.
- Installation simplicity: Tool-free mounting and pre-applied thermal paste reduce build time. If you’re a first-time builder, prioritize models with straightforward installation steps.
- RAM clearance and case support: Check the overall height and whether the cooler blocks RAM slots or PCIe lanes. Large heatsinks may require taller cases or alternate RAM configurations.
- Materials and durability: Copper cores and dense aluminum fins improve heat transfer but add weight. Choose a build that tolerates heavier coolers if needed.
Frequently Asked Questions
- What does LGA 1151 imply for heatsink compatibility? LGA 1151 refers to the socket type; choose a cooler with mounting hardware compatible with LGA 1151 to ensure proper fit and contact with the CPU.
- Is a dual-fan cooler always better for LGA 1151? Not always. Dual-fan designs offer higher cooling capacity but require space. For compact builds, a single-fan compact cooler can be sufficient.
- Do I need thermal paste with these coolers? Some come with pre-applied paste; others require you to apply paste manually. Follow the product instructions for best results.
- Will these coolers fit in mini-ITX cases? Compatibility depends on the cooler height and clearance. Check your case’s CPU cooler clearance spec before purchase.
- Can I upgrade from a stock cooler to a more powerful one for gaming? Yes, upgrading can improve thermals and noise levels, but ensure the new cooler fits your motherboard, case, and RAM layout.
- Are copper-core coolers heavier? Yes, copper cores add weight and may require sturdy mounting. Verify case and motherboard support for heavier components.
