DeepCool ASSASSIN IV CPU Air Cooler

The “Air” Apparent

The ASSASSIN IV is the latest evolution in the ASSASSIN series, claiming the air-cooling crown in both cooling capacity and ultra-quiet operation.


Beauty in Simplicity

Designed with clean, elegant lines, the ASSASSIN IV combines aesthetics with function:

  • Sleek, minimalist exterior
  • Optimized airflow through the twin fin towers
  • Maximum compatibility with surrounding components

Silent or Extreme – You Decide

With a simple slide of a switch, the ASSASSIN IV instantly adapts to your needs:

  • Silent Mode: Whisper-quiet operation when low noise is the top priority
  • Performance Mode: Unrestricted cooling power when only peak performance matters

In either mode, the ASSASSIN IV delivers outstanding results.


Let It Shine

The thoughtfully designed case is clean and streamlined, helping guide air efficiently through the fin towers. A relocatable 120 mm fan provides unobstructed clearance for high-profile RGB RAM, keeping your system both cool and visually impressive.


RAM Clearance

  • Intel LGA1700/1200/115X: Unobstructed
  • Intel LGA20XX: 63 mm
  • AMD AM4/AM5: Unobstructed

Be Cool, Be Calm

Ultra-quiet operation is achieved through three-phase, six-stage fan motors engineered for low voltage and power consumption. DeepCool backs the ASSASSIN IV with 6 years of limited warranty coverage.


Exceptional by Design

The ASSASSIN IV is built for high-performance efficiency:

  • Seven heat pipes for improved heat transfer
  • Dual fin-array heat sink towers for enhanced cooling performance
  • Included DM9 thermal paste, meeting rigorous industrial application standards

Streamlined Installation

Larger air coolers are often difficult to install, so the ASSASSIN IV has been engineered with user-friendly hardware and installation in mind. Even the magnetic top fan cover is designed to make the process as simple as possible.
