DeepCool Assassin IV CPU Air Cooler

Sophisticated Elegance

The ASSASSIN returns with a new aesthetic and efficient cooling capacity. The ASSASSIN IV provides exceptional performance and is armed with seven heat pipes and newly designed 120 and 140mm FDB fans. 

Beauty In Simplicity

The elegant design of the ASSASSIN IV is not just visually pleasing; it also leads to optimal air flow and maximum compatibility.

In Quiet or Performance Mode, The Assassin IV is the obvious choice

With a simple slide of a switch, the ASSASSIN IV can morph from a whisper-quiet cooler when low noise is of the utmost importance to the efficient cooling force DeepCool air coolers are known for.

Let It Shine!

The Assassin IV's case is clean, sleek, and helps channel air through the fin towers, while the relocatable 120mm fan provides unobstructed clearance for high-profile RGB RAM.


RAM Clearance


Intel LGA1700/1200/115X: Unobstructed

Intel LGA20XX: 63mm

AMD: AM4/AM5: Unobstructed


Due to differences in motherboard layouts, the following motherboards are not compatible with the ASSASSIN IV: ROG STRIX Z790-H GAMING WIFI, ROG STRIX Z690-E GAMING WIFI, MSI MEG X570 GODLIKE, MSI B650M APE WIFI, ROG CROSSHAIR X670E GENE, and MSI MEG Z790 ACE.

Be Cool, Be Calm

A key factor in the ASSASSIN IV's extremely silent operation is the use of three-phase, six-pole fan motors with low voltage and power consumption. DeepCool is so confident in our new design that the ASSASSIN IV comes with 6 years of limited warranty coverage!

Exceptional by Design

Featuring seven heat pipes that deliver improved heat transfer through two fin-array heat sink towers for high performance efficiency. The included DM9 thermal paste meets the rigorous standards used in industrial applications.
