Thermalright Frozen Prism 240 Black AIO Liquid CPU Cooler - Quiet High

Our review of the Thermalright Frozen Prism 240 Black finds it best suited to PC builders who want a balanced, reliable 240mm all-in-one cooler that emphasizes durable construction and solid cooling performance. The single biggest reason to buy is its combination of a flat copper base water block, a 240mm black aluminum fin radiator and 120mm PWM fans that together remove heat effectively while offering broad socket compatibility for modern AMD and Intel platforms. This review looks at build quality, noise, installation and real-world cooling for typical desktop workloads.

Key Features

• Flat copper base: Provides direct, efficient thermal transfer from the CPU to the loop for improved temperature control under sustained load.
• 240mm black aluminum radiator: A two-fan radiator layout moves heat away quickly while fitting most mid and full tower cases.
• 2120mm polymer woven tubing: Durable protective hoses reduce kinking and help extend the life of the loop.
• TL-E12 V2 120mm PWM fans: Fans automatically adjust speed up to 1850RPM to balance airflow and noise depending on CPU temperature.
• Fourth-generation pump with ARGB cover: Low vibration pump design with a removable magnetic top and 5V ARGB lighting for a clean look and long service life.
• Wide socket compatibility: Includes mounting hardware for AMD AM4/AM5 and Intel LGA115x/1200/1700/2066 platforms for straightforward installation.

Who It's For

This cooler is a fit for mainstream and enthusiast builders who want an affordable 240mm AIO with good build quality and wide platform support; reviewers noted that it keeps CPU cores comfortably cool in everyday and gaming loads. It is also a sensible upgrade for users moving from air cooling to liquid cooling who appreciate the included PWM fans and a durable copper cold plate.

Those who need the absolute lowest noise floor in a passive or near-silent system, or builders who require exotic radiator sizes or custom loop features, should look elsewhere; a few users reported mixed experiences with noise, so silence-focused builds may need additional fan tuning or an alternative model.

Pros & Cons

Pros

• Solid cooling performance from the flat copper base and 240mm radiator, keeping cores well controlled under load.
• Robust build quality with polymer woven tubing and an all-aluminum pump shell rated for long life.
• Helpful automatic fan speed control via PWM and a removable magnetic pump cover with ARGB for simple customization.

Cons

• Noise level is mixed in user reports, so some systems may need fan curves adjusted to achieve desired quietness.
• Not a replacement for large custom loops or builders seeking ultra-compact or passive cooling solutions.

Frequently Asked Questions

Will this fit in standard mid tower cases?
Yes. The 240mm radiator fits most mid and full tower cases that support two 120mm fans on a 240mm bracket.

Is the cooler compatible with AM5 and modern Intel sockets?
Yes. Mounting hardware is provided for AMD AM4 and AM5 and a range of Intel sockets including LGA115x, 1200 and 1700.

How loud is the pump and fans?
Noise reports are mixed; the pump is designed for low vibration and the fans are PWM-controlled up to 1850RPM, so setting a custom fan curve will help reach a quieter balance.
