Compact Intel LGA 115X cooler

The BGears b-Cooler LGA 115X is a low-profile air cooler built for Intel sockets 7775, 1150, 1151, 1155 and 1156. It fits processors with a thermal design power up to 90 W. The 57 mm height suits small-form-factor chassis where taller towers cannot be installed. Builders upgrading legacy office or home PCs will find the socket coverage matches many older platforms.

Pre-applied grease and push-pin mounting

Thermal paste is already on the copper-core base so no separate tube is needed. The push-pin mechanism locks the unit onto the motherboard without tools or a back-plate. A 4-pin PWM connector lets the motherboard control the 90 mm fan speed automatically. No extra brackets, adapters or software utilities are included in the package.

90 W TDP rating decides suitability

The cooler is rated for 90 W maximum heat dissipation. Systems running CPUs that exceed this limit will throttle or overheat under sustained load. Buyers who need more thermal headroom for higher-power processors must choose a different solution. The 90 mm fan spins between 1000 and 2400 RPM, delivering 26 to 52 CFM at 16 to 24 dBA.

Questions about this item

How often should I replace the fluid dynamic bearing fan on the BGears b-Cooler LGA 115X?

The fluid dynamic bearing fan is rated for long life and typically does not need scheduled replacement; monitor noise or RPM drop after several years of continuous use.

What thermal limit appears first when the cooler runs at its 90W TDP rating for extended periods?

At the rated 90W TDP the 90mm fan must spin toward 2400 RPM to maintain temperatures, so fan speed headroom becomes the limiting factor before the copper-core heatsink saturates.

How loud and hot does the 90mm PWM fan get when it runs all day at full load?

At full load the fan reaches 2400 RPM producing 24 dBA and 52 CFM, while the heatsink stays within its 57mm height envelope and draws power only from the 4-pin connector.
