Cons
- No installation manual
Cooling Performance: The Arctic Liquid Freezer II 240 ARGB delivers exceptional cooling performance thanks to its solid pump block and two identical fans, which have an air pressure of 48.8 CFM and a static pressure of 1.85mm H20. In my testing with the i9-12900K OC, the Liquid Freezer II peaked at a delta temperature of just 38.3C under load.
Build Quality: What stands out to me about the Liquid Freezer II 240 A-RGB is obviously the pump unit which comes with a 40mm VRM fan that can spin up to a speed of 3000 RPM. Arctic has used a 240mm radiator that has a thickness of 38mm, which adds to the overall build quality of the cooler. The radiator also comes equipped with rubber pads that absorb vibrations.
Aesthetics: The pump block is rather simple in design, but the fans do have beautiful RGB lighting in my opinion. While Arctic does not include an ARGB controller, the RGB can still be controlled using software such as ASUS Aura Sync, MSI Mystic Light, and RGB Fusion 2.0. Arctic has also used a 450mm tube with braided sleeves that make the design stand out.
We also captured some shots during our review:
You want top-notch cooling performance: With a rated TDP of over 200W, The Liquid Freezer II is able to handle even the most power-hungry processors according to my testing, even while overclocking.
You want a built-in VRM fan: The inclusion of the VRM fan into the pump block can especially be a game-changer for motherboards with weak VRM cooling systems.

The Silencio FP120 fan has an air pressure of 2.9mm H20 and an airflow of 42 CFM. Even while spinning at the maximum speed, I found the peak fan noise level to be quite comfortable at 26 dBA.
Build Quality: Unlike most air coolers that use fan clips to mount the fan, Cooler Master uses fan brackets that make the installation of an extra fan much easier. An extra set of fan clips is also present with the cooler, allowing you to add another fan. Due to its slim design, RAM and GPU clearance should was not an issue in my experience, and the build quality is adequate.
Aesthetics: Cooler Master has launched the Black Edition of the Hyper 212, which performs just as well as the other iterations of the Hyper 212 but with an all-black aesthetic. The clean design fits really well with the industrial theme of the Hyper 212, and while the cooler does not have any RGB lighting, it really does look attractive in a case.
The Cooler Master Hyper 212 has been around for a long time, and for good reason. With a little bit of digging, even the Black Edition can be found for under $50, which gives it a gigantic advantage over the other coolers in terms of value. This cooler will not let you down if you are looking for an entry-level cooler for your new build.

Thermal Benchmarks
To make sure the coolers I recommend offer truly the best bang for the buck under $100, my team and I tested all of them, here are our results:
How We Tested & Picked The Best CPU Coolers Under $100
Ensure you’re aware of these pivotal factors when you’re shopping for a CPU cooler in a budget under $100.
- Type: CPU coolers come in many different types and sizes such as dual-tower air coolers, single-tower air coolers, All-In-One liquid coolers, and low-profile air coolers. A larger dual tower CPU cooler with a huge footprint would require an adequate casing to fit into; whereas, smaller low-profile coolers can even be installed in small form factor cases.
- Compatibility: Before purchasing your next cooler, you need to make sure it is compatible with your processor. This can be done by visiting the manufacturer’s website. You also need to make sure you have the correct mounting brackets. In case you are not provided the required mounting brackets with the cooler, extra ones can be bought separately.
- Efficiency and Performance: Performance is essentially the most important factor when choosing a cooler for beefier processors. There is no point in buying a CPU cooler that can’t perfectly cool your CPU. A relatively simple way of measuring the performance your CPU cooler can deliver is by looking at its rated TDP.
- Size and Clearance: CPU coolers are generally available in a number of sizes; picking the right size depends on the type of case you have. Usually, mid-tower cases have a CPU cooler clearance of up to 165mm. One must also ensure that there is no interference between the RAM kits and the CPU cooler itself.
