Thermalright Assassin X120 Refined SE CPU Air Cooler
The Assassin X120 Refined SE from Thermalright combines compact dimensions with robust cooling performance. The cooler uses four heat pipes and a TL-C12C PWM fan to balance airflow and noise. Its aluminum heatsink cover contributes to a lightweight yet effective cooling solution for Intel LGA 1151 and other modern sockets. The SE version emphasizes ARGB-ready lighting for customizable aesthetics, making it a viable option for visually oriented build projects. The unit’s dimensions and weight are designed to fit most mid-tower cases, while the metal mount hardware supports straightforward installation on compatible platforms.
Key features include: four heat pipes for efficient heat transfer, a 120 mm PWM fan, and broad compatibility with LGA 1151 as well as AMD AM4/AM5 platforms. The fan operates at ~1550 RPM with a maximum airflow around 66 CFM, delivering solid cooling without excessive noise. Users should ensure case clearance given its height, and pairing with a quality thermal paste can optimize thermal transfer. For those seeking a quiet, dependable cooler for everyday gaming or productivity, this Thermalright option offers a balanced mix of performance and style.
Thermalright Assassin X120 Refined SE ARGB CPU Cooler
The SE ARGB version of the Assassin X120 extends the standard model with addressable RGB lighting to deliver a dynamic aesthetic for systems that emphasize visuals as well as performance. Built around the same four-heat-pipe design, it uses a TL-C12C-S PWM fan for smooth operation and efficient cooling. The aluminum heatsink and ARGB integration offer a compelling blend for gamers and enthusiasts who want eye-catching illumination without compromising cooling performance for LGA 1151 and newer Intel sockets or AMD platforms.
Performance-wise, expect similar cooling metrics to the non-ARGB version: around 66 CFM, low to moderate noise levels at typical gaming loads, and straightforward installation with metal fasteners for cross-brand compatibility. This variant suits builds where lighting effects are a priority alongside reliable CPU temperatures, especially in compact or glass-panel cases where airflow direction is a consideration.
Cooler Master i30 CPU Cooler
The Cooler Master i30 is a compact cooler designed for Intel 1150/1151/1155/1156 sockets with a 92 mm cooling fan. It emphasizes low-noise operation and compact dimensions suitable for smaller PC builds or tight cases. The fan’s 22 dBA rating and a high RPM around 2200 help maintain effective CPU cooling while keeping acoustic levels subdued. This cooler is ideal for users seeking a budget-friendly option without sacrificing core cooling needs for mid-range CPUs, including many LGA 1151 configurations.
Key considerations include the 90 x 30 mm heatsink and the 92 mm fan size, which influence case compatibility and clearance. As with most air coolers, proper application of thermal paste and ensuring unobstructed airflow from the case fan setup will maximize performance. Compared to larger tower coolers, the i30 offers simpler installation and adequate performance for typical office, HTPC, or light-gaming setups on LGA 1151 systems.
QUETTERLEE Replacement New CPU Cooling Fan With Heatsink
This QUETTERLEE replacement kit targets Intel LGA1150/1151/1155/1156 platforms with a 4-pin, 12V cooling fan and integrated heatsink. It’s positioned as a direct replacement option for systems requiring a straightforward upgrade to maintain CPU cooling, especially in older or budget builds. The kit’s compatibility with a wide range of 115x processors makes it versatile for various Intel generations, and the included mounting hardware simplifies swap-outs on compatible boards.
Practical considerations include verifying the exact model numbers and device compatibility before purchase, as the kit is designed to mitigate common cooling failures. This option suits users performing routine maintenance, or those who want a spare cooling solution for estate or office PCs using LGA115x sockets. Installation typically requires standard fan connectors and basic mounting hardware found in most PC builds.
i50 CPU Cooler – 92mm Low Noise Cooling
The i50 CPU Cooler from Toptekits is a compact solution featuring a 92 mm fan designed for low noise operation. It’s compatible with LGA 1150/1151/1155/1156 sockets, making it suitable for HTPCs or compact builds where space is at a premium. The unit includes thermal grease pre-applied to the heatsink, enabling quick installation and initial thermal performance without extra prep work. This makes it a practical option for budget-conscious builders who still require reliable cooling on LGA 1151 systems.
Despite its small footprint, the i50 aims to balance airflow with quiet operation, delivering an approachable entry point for users new to DIY cooling. When choosing between compact air coolers, consider case clearance, RAM clearance (if a tall heatsink is used), and the processor’s turbo or boost behavior to ensure sustained performance under load. This cooler offers a straightforward path to improved thermals for standard office-to-gaming workloads on LGA 1151 systems.
Buying Guide: Key Purchase Considerations For LGA 1151 Cooling
- Socket compatibility: Confirm support for LGA 1151 and check for additional supported platforms (1150, 1155, 1156, etc.) to future-proof or reuse on a broader range of builds.
- Airflow and noise profile: Look for fans with PWM control and a balance between CFM and decibel output. Lower noise is essential for quiet builds, while higher CFM improves sustained loads.
- Heatsink design: Four-heat-pipe designs generally offer better heat transfer than basic fin stacks. Pay attention to total height and case clearance in compact builds.
- ARGB and aesthetics: If lighting matters, ARGB-capable coolers add visual flair; ensure your motherboard supports RGB control or use standalone lighting options if needed.
- Installation effort: Some coolers use universal mounting across multiple sockets; others require specific brackets. Check installation manuals for screw patterns and backplate compatibility.
- Upgrade path: If you plan future Intel generations, select coolers with broad compatibility (AM4/AM5 or newer Intel sockets) to minimize future purchases.
- Thermal paste and pre-applied paste: Some units ship with pre-applied paste; if not, plan to use a quality thermal compound to maximize contact efficiency.
When evaluating options, weigh the balance between price, noise, and cooling capacity for your PC’s workload. For mid-range gaming or multitasking on LGA 1151, a compact cooler with four heat pipes and a 120 mm fan generally delivers dependable performance with reasonable noise. For aesthetically focused builds, ARGB variants provide enhanced lighting without sacrificing cooling. For smaller cases, compact 92 mm options can fit where space is at a premium but may trade off some thermal headroom.
