Silverstone SST-AR11 92mm low-profile CPU cooler 47mm

Low-profile 47 mm cooler for Intel LGA 115x

The Silverstone SST-AR11 is a 92 mm tower cooler that stands only 47 mm tall, making it suitable for slim HTPC or small-form-factor chassis. Four 6 mm copper heat pipes use direct-contact technology to move heat into an aluminum fin stack, while a horizontal 92 mm PWM fan pushes up to 55.76 CFM at a maximum of 44.5 dBA. The unit weighs 290 g and fits the Intel LGA 1150, 1151, 1155 and 1156 mounting holes.

Suits builds limited to 47 mm height.

This cooler targets system integrators and DIY builders who need a 95 W-class thermal solution in a 47 mm envelope. The dual ball-bearing fan spins between 1200 and 3000 RPM, delivering the rated airflow within the specified noise ceiling. Builders targeting processors above the rated thermal range, or who require a taller heatsink for additional surface area, should consider alternative designs.

47 mm maximum height decides fit

The single specification that determines compatibility is the 47 mm overall height, measured with the fan installed. Verify the chassis CPU-cooler clearance before purchase; if the case allows more height, a larger cooler may offer lower noise or higher capacity, but this model is defined by its 47 mm limit.
