Thermaltake Gravity i2 95W CPU Cooler
The Gravity i2 is a compact, low-profile cooler designed for Intel LGA 1200/1156/1155/1150/1151 sockets. It emphasizes quiet operation with a noise level near 21.3 decibels and an airflow around 31.343 CFM. This model is best for small-form-factor builds or systems where clearance matters, and where the processor’s power needs are modest.
Who it’s best for: users seeking a slim cooler that fits tighter cases without sacrificing basic cooling performance. Why selected: strong compatibility across several generations and a notably quiet profile for daily computing tasks.
Caution: It is optimized for lower power CPUs; consider higher-TDP CPUs if thermal headroom is a priority.
Cooler Master Hyper 212 Black CPU Air Cooler
The Hyper 212 Black is a versatile air cooler with four heat pipes and a copper base, delivering solid cooling for mainstream CPUs. The SickleFlow 120 Edge PWM fan enables dynamic speed control from about 690 to 2,500 RPM, balancing cooling performance with low noise. Installation design has been streamlined to accommodate a variety of sockets, including older LGA 1155 as well as newer platforms.
Who it’s best for: users needing dependable, well-rounded cooling for Intel i5/i7 or AMD Ryzen systems. Why selected: proven performance for a broad range of cases and easy integration with standard brackets.
Caution: Some users may prefer a thinner or more compact model for very small cases; check clearance with tall RAM modules.
Thermaltake UX150 ARGB CPU Cooler
The UX150 ARGB is a larger-capacity air cooler featuring a copper base, aluminum fins, and a 130mm PWM fan. It supports Intel LGA 1851/1700/1200/1156/1155/1151/1150 and is positioned for flexible builds, including small form factors where height is around 72mm. Its Infinity Mirror lighting adds a visual accent while maintaining solid cooling performance.
Who it’s best for: builders wanting an eye-catching cooler with broad socket compatibility. Why selected: combines reliable cooling with striking RGB lighting and compatibility across multiple Intel generations.
Caution: The visual feature increases complexity; ensure your motherboard’s header availability for ARGB control in your case.
Thermalright Assassin X120R SE CPU Cooler
The Assassin X120R SE uses four heat pipes with a copper base and aluminum fins, paired with the TL-C12C PWM fan. It’s designed for high-efficiency cooling and supports AMD AM4/AM5 and Intel LGA sockets including 1150/1151/1155/1200 and beyond. The sealed, low-noise operation aims to deliver quiet performance under heavier loads.
Who it’s best for: users needing robust cooling with a smaller footprint in mid- to high-end builds. Why selected: strong thermals with a PWM fan and a proven design from Thermalright.
Caution: taller than ultra-compact options; verify space clearance in compact cases before purchase.
Thermalright Assassin X 120R SE V2 CPU Cooler
The Assassin X 120R SE V2 refines the 120R SE design with a 120mm RGB PWM fan and S-FDB bearing for quieter operation. It remains compatible with Intel LGA 1150/1151/1155/1200 and AMD AM4/AM5, delivering similar performance with improved aesthetics and noise performance. The cooler uses a pure copper base and four heat pipes for efficient heat transfer.
Who it’s best for: RGB enthusiasts and users seeking a quietly efficient cooler with a modern look. Why selected: combines cooling performance with RGB and low-noise operation for flexible builds.
Caution: RGB features require motherboard headers and software support; verify compatibility with your system’s RGB control setup.
Buying Guide: Key Considerations For LGA 1155 CPU Fans
- Socket compatibility: Ensure the cooler supports LGA 1155 and related sockets in your build. Many options here also fit LGA 1150/1151/1200, offering future-proofing for upgrades.
- Cooler height and clearance: Check your case clearance, RAM height, and PCIe card spacing to avoid interference with tall memory or big fans.
- Thermal design power (TDP): Match the cooler’s cooling capacity to your CPU’s TDP to prevent throttling or excessive fan noise.
- Noise and fan control: PWM fans enable dynamic speed control for quieter operation during light tasks and higher cooling when needed.
- Aesthetics and connectors: ARGB/RGB features look appealing in builds with lighting, but ensure motherboard headers are available for full control.
- Installation and mounting: Some designs offer easier mounting or redesigned brackets for compatibility with multiple platforms.
FAQ
- Q: Can these coolers fit the original LGA 1155 board? A: Yes, all listed models include support for LGA 1155 or offer broad Intel socket compatibility that includes 115x series.
- Q: Is an RGB cooler necessary for LGA 1155 builds? A: RGB is optional; it’s mainly for aesthetics and does not affect cooling performance.
- Q: Do these coolers fit in compact cases? A: Some are low-profile or compact, like Gravity i2, but always verify case clearance before purchase.
