Details and Installation

After installing both the fans (The Red & Black Combo over the heat sink makes the cooler damn attractive) the Assassin II is not only quite heavy (1479g) but also quite large (167mm tall, 143mm wide and 158mm long). The 120mm PWM fan can spin up to 1400RPM to produce 68.06CFM of airflow with 27.3dBA of noise while the 140mm PWM fan can spin up to 1200RPM to produce 70.08CFM of airflow with 26.5dBA of noise. The heat sink consists of 8 nickel-plated copper heat pies of 6cm each.

The base of the heat-sink contains mirror-like finish and is very much prone to scratches if not handled with care.

Installing a cooler of this size should be a struggle, but Deepcool does well to keep the entire process as pain-free as possible. Mounting hardware for many of the latest Intel and AMD sockets is provided, and on LGA 1150 the step-by-step manual was straightforward to follow. One can easily follow the guide to install this giant without a hassle.

The problem which I faced after installing the cooler is that I was not able to use my 1st and 2nd RAM slots in the Mobo as space was occupied by this cooler and I was in possession of High Profile RAM’s making 2 RAM’s and their slot completely useless. Low profile RAM can still be used though I didn’t test myself.


After Installation of the product make sure to carry the mobo by holding the cooler as after complete installation it becomes heavy.
