Low-profile cooler for Intel LGA 115x builds

The Silverstone NT09-115X is a 45 mm tall air cooler designed for compact Intel systems. It supports LGA 1150, 1151, 1155 and 1156 sockets with a 65 W TDP rating. The unit weighs 0.47 lb and fits inside slim chassis where standard tower coolers cannot be installed.

92 mm PWM fan and vertical fin stack

A custom 92 mm PWM fan spins between 550 and 2500 RPM to deliver 10.34 to 47.0 CFM of airflow at 18.5 to 32.0 dBA. The fan mounts vertically on an extruded aluminium fin array with an aluminium core. A reinforced back-plate reduces motherboard flex and improves contact pressure without requiring case-specific brackets.

Reinforced back-plate included

The bundled back-plate strengthens the mounting area to prevent PCB bending during installation or transport. No additional brackets, thermal paste or software utilities are mentioned in the specifications, so builders should verify socket clearance and prepare their own interface material.

Questions about this item

Will the 65 W TDP limit throttle my CPU during long workloads?

The cooler is rated for 65 W TDP, so sustained loads above that may cause thermal throttling.

How loud does the 92 mm PWM fan get at full 2500 RPM?

At maximum speed the fan produces 32.0 dBA with 47.0 CFM airflow.

Does the mounting kit fit Intel LGA 1151 motherboards?

Yes, the included hardware supports LGA 1150, 1151, 1155 and 1156 sockets.
