Black, ARCTIC Alpine AM4 Passive, Silent CPU Cooler for AMD Socket AM4, Easy Installation and Long Service Life, 99 x 70 mm

ARCTIC #ad - Passive amd cpu cooler: the alpine am4 passive comes without a fan and yet provides enough power to keep all compatible AMD AM4 processors up to 47 Watts at bay. Dust and maintenance free: No fan means no dust and no maintenance over time.

Optimal compatibility: fast and easy to install and extremely reliable, the Alpine AM4 Passive mounting system is compatible with AMDs AM4 socket, which is used for Ryzen CPU, it is fool-proof to install and absolutely transport safe. Black anodising for improved heat-dissipation: The micro-porosity resulting from the heatsink surface treatment optimises heat exchange between aluminium and surrounding air, thus the cooling performance in passive mode is greatly improved. Pre-applied mx-2 thermal paste: Thanks to the pre-applied MX-2 thermal compound, a quick and clean installation is guaranteed.

Max. Cooling Capacity 150 Watts, Silent high Performance Cooler, Semi Passive Tower CPU Cooler for Intel and AMD, Grey/Black, 100 mm PWM Fan, ARCTIC Freezer 12

ARCTIC #ad - Decisively improved: as semi passive cooler, the Freezer 12 also works extremely efficiently as the fan only starts up at a PWM signal with 40 % pulse width. Optimal compatibility: fast and easy to install on AMD AM4 and Intel 115x, 2066, 2011-3.

Semi passive cooling: the 100 mm fan only starts up at a PWM signal with 40 % pulse width. This is leading to greater airflow and cooling at lower noise level. Innovative ventilation: fluidic analysis and long testing hours allowed us to push the fan efficiency boundary further. Easy installation & safe transportation: Thanks to different mounting models for various sockets and a backplate, the Freezer 12 is not only fool-proof to install, but also absolutely transport safe. This saves energy, extends the service life and makes the cooler at low load completely silent.

AM4 with 120 mm PWM Fan, ARCTIC Freezer 34 CO – Semi Passive Tower CPU Cooler for Intel 115X/2011-3/2066 and AMD, Silent High Performance Cooler up to 150W TDP – Black

ARCTIC #ad - Even ram modules with larger heat sinks can be mounted without any issues. High performance for high-end cpu: the contact surface of the Freezer 34 CO heat pipes does not cover the full heat spreader, but is right where the processor DIE is and covers even the largest versions 18 core.

Improved heat dissipation: evenly spread direct-touch heat pipes and an optimised heatsink design with 54 cooling fins lead to an ideal heat dissipation for the Freezer 34 CO. Easy installation & secure hold: fast and easy to install, the mounting system of the Freezer 34 CO is compatible with Intel and AMD sockets.

Thanks to a back plate and its low weight it's also transport safe. Compatibility: the cpu cooler mounting system freezer 34 by arctic mounting system is compatible with the Intel Sockets: 115x, 2011-3*, 2066* *SQUARE ILM 80 x 980 mm spacing only and AMD: AM4. Optimal ram compatibility: thanks to the compact dimensions 124 mm x 157 mm x 86 mm, there are no restrictions when using RAM modules.
