DeepCool ASSASSIN IV CPU Cooler

DeepCool ASSASSIN IV is an air cooler for processors, aimed at more serious configurations where you seek stable temperatures without hearing the fans "roaring". It combines a large 140 mm fan with a low noise level of up to 22.6 dB(A), making it suitable for quiet gaming or work machines. Support for modern sockets like LGA 1700, LGA 1851, AM4, and AM5 makes it a flexible choice for current and future upgrades. If you are looking for a balance between efficiency and acoustic comfort, this cooler fits right in.

What you get

With the large 140 x 140 x 25 mm fan, DeepCool ASSASSIN IV can move up to 63.76 CFM of air, which is important for quickly dissipating heat from the radiator without the fan needing to spin at insane speeds. The range of 500~1350 RPM allows for very quiet idle at low speeds and stable cooling under higher load, without crossing the threshold of annoying noise. The connector is a standard 4 PIN PWM, so you can adjust the curves through your BIOS or motherboard software and choose whether your priority is absolute quiet mode or more aggressive cooling. In combination with a maximum static pressure of up to 1.58 mmAq, the fan performs well even through dense radiators, which is key for the efficiency of large air towers.

• Air cooling from DeepCool, relying on a large 140 mm fan for effective and relatively quiet heat dissipation.
• Wide compatibility with CPU sockets like LGA 1700, LGA 1851, LGA 2066, LGA 2011/2011-v3, and AM4/AM5, making upgrades easier without changing the cooler.
• Operating range of 500~1350 RPM±10%, allowing for quiet mode at low load and stronger cooling when the CPU is under serious load.
• Maximum airflow of up to 63.76 CFM, providing good circulation of the radiator and lower temperatures during prolonged use.
• Low noise level of up to ≤22.6 dB(A), which is suitable for systems where silence is a priority — streaming, sound recording, or just quiet gaming.
• Maximum static pressure of up to 1.58 mmAq, helping air to pass effectively through the dense fins of the radiator.
• Standard 4 PIN PWM connector for easy fan control through BIOS and flexible management of cooling and noise profiles.

Who it is suitable for

This cooler is suitable if you are building a mid-range to more serious build on Intel or AMD and want reliable air cooling with an emphasis on quietness. It is a good choice for gaming configurations, productivity, and even heavier loads, as long as you are not aiming for extreme overclocking. If you are looking for a maximum compact solution for a mini-ITX case, you may have limitations due to size.

With the combination of a large 140 mm fan, low noise level, and wide socket compatibility, DeepCool ASSASSIN IV is a solid choice if you want serious air cooling that simply does its job quietly and reliably.
