Slim and compact design
For multimedia and graphics systems with limited space
Thanks to its asymmetrical and compact design, Pure Rock Slim is the perfect choice for PC cases with limited space. Nevertheless, it allows full configuration of RAM memory banks. For this reason, the cooler is compatible with a variety of installation parts and allows many installation options.
Very good cooling efficiency.
A good choice for beginners systems of all kinds.
Pure Rock Slim is placed in the Essential category. With 120W TDP, it offers an amazingly high cooling performance for this performance class.
High-performance heat pipes:
The important feature behind top performance
The Pure Rock Slim has three heat pipes with aluminium caps. These are the key of its high cooling performance, because they transport the heat optimally to the cooling fins.
Noise optimised in operation.
Only 25.4 dB(A) even with PWM function.
The volume-optimised PWM fan with seven fan blades and high-quality sleeve bearing ensures the optimal balance between necessary cooling and smoothness. The fan blades are stream-optimised to reduce noise generating turbulence.
