The DeepCool ASSASSIN IV WH CPU Cooler features a dual tower design with a 140mm PWM fan operating at 1400RPM, ensuring optimal airflow and heat dissipation. Engineered for universal compatibility, it offers exceptional cooling performance, ideal for high-end gaming rigs. Enjoy quiet operation and striking aesthetics with this powerful cooler. The ASSASSIN IV WH provides exceptional performance and is armed with seven heat pipes and newly designed 120 and 140mm FDB fans. Its elegant white design is visually pleasing and leads to optimal air flow and maximum compatibility. The case channels 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, certain motherboards are not compatible. A key factor in the ASSASSIN IV WH's extremely silent operation is the use of three-phase six-pole fan motors with low voltage and power consumption. This cooler comes with 6 years of limited warranty coverage. 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 rigorous industrial application standards.
