The Thermalright PS120SE ARGB is a dual-tower air cooler that punches far above its price segment. Its 7x6mm heat pipes use AGHP 4.0 technology, which counteracts gravity-driven performance loss in vertically oriented cases—a detail typically reserved for much more expensive coolers. The dual TL-C12B-S V2 PWM fans operate at a maximum of 1500 RPM, pushing 66.17 CFM of air at a noise floor of just 25.6 dB(A). That noise level is among the lowest in its class, making this an excellent choice for noise-sensitive builds.

The main body measures 154mm in height, fitting most mid-tower cases, and the anodized black frosted top with a pure copper base provides efficient heat transfer. Verified customer reports show this cooler keeping a Ryzen 9 9950X3D at a maximum of 78°C under sustained load with minimal throttling—a remarkable figure for a dual-tower cooler. The ARGB lighting is handled via a 5V 3-pin header and can be fully synchronized with the motherboard ecosystem.

While the overall build quality is strong, the cooler’s size can interfere with RAM slots if the front fan is not positioned slightly higher. The included thermal paste is thick and requires a proper pea-size application. For the combination of cooling performance, silence, and premium features like ARGB, this cooler offers the most compelling value proposition on the current market for mid-range to high-end builds.

The ID-COOLING FROZN A620 is a dual-tower cooler that insists on fitting into tighter spaces. At 153mm tall, it is shorter than most of its dual-tower peers, making it a viable option for cases with strict side-panel clearance (like the Dan A3). The six 6mm copper heat pipes transfer heat to the dual 120mm FDB fans, which spin up to 1800 RPM and produce a maximum airflow of 78.25 CFM with a noise ceiling of 29.85 dB(A).

The all-black design blends into dark case interiors, and the 36mm RAM clearance (63mm with the cut-out fin) is generous enough for most standard memory kits. Verified customer feedback highlights its ability to cool an Intel Core i7-13700K 4°C better than a Thermalright Peerless Assassin in a real-world build. The mounting system covers LGA1700, LGA1851, and AMD AM5/AM4 out of the box, and installation is straightforward when done before placing the motherboard in the case.

Some users report that the mounting bracket screws can be finicky to align, and the fans produce a noticeable deep hum at maximum RPM. At 40% speed with a custom fan curve, the noise profile becomes much more acceptable. This cooler is best suited for users who need the performance of a dual-tower but are limited by case width or height.
