GlacialTech Launches Igloo 1800 Series CPU Coolers: A Space and Cooling Balanced Solution Designed for Intel LGA1851 CPUs in SFF Cases
   
   
 
 

[Taipei, January 28, 2026] – GlacialTech, a globally renowned leader in thermal solutions, announced the official release of four new CPU coolers: the Igloo 1833, Igloo 1837, Igloo 1842, and Igloo 1857. Specifically designed for the new generation of Intel LGA1851 CPUs, this Igloo 1800 series aims to perfectly address the cooling challenges within 8-liter small form factor (SFF) cases, striving for an optimal balance between space and performance.

The radial fin array combined with a downblow fan effectively cools critical electronic components around the CPU, significantly lowering their temperatures and enhancing the system's overall stability and lifespan.

Equipped with a unique 9cm slim axial fan, the cooler not only minimizes its overall height but also ensures sufficient air pressure and airflow within the limited vertical space. This effectively dissipates heat from the fins, preventing the CPU from overheating.
