Low-Profile 60 mm Cooler

This 60 mm tall air cooler combines a 120 mm ARGB fan with an aluminium and copper heatsink. It mounts on Intel LGA 1156, 1155, 1151 and 1150 sockets using a 4-pin PWM connector. The rifle-bearing fan spins between 650 and 2000 RPM, delivering up to 37 CFM at a maximum of 28 dBA. Its slim profile targets all-in-one systems and compact chassis where standard tower coolers cannot fit.

Builders With LGA 115X Systems Only

The cooler suits owners of older Intel platforms who need a thin, addressable-RGB solution for a space-constrained case. It will not fit sockets outside the LGA 115X family, so builders upgrading to newer platforms must choose a different cooler. Users who require higher static pressure or greater thermal headroom than 37 CFM provides should also look elsewhere.

60 mm Maximum Cooler Height

The heatsink measures 120 x 120 x 60 mm, making the 60 mm overall height the single dimension that determines whether this unit clears your case and motherboard layout. Verify that your chassis allows at least 60 mm of CPU cooler clearance before purchase.

Questions about this item

How often will the 120 mm rifle-bearing fan need replacement in this Cooler Master RR-I71C-20PA-B1 cooler?

The 120 mm fan uses a rifle bearing rated for long life expectancy; no fixed replacement interval is defined, but bearing wear is the only moving part that can require service.

What thermal limit appears first when the 60 mm tall heatsink runs at the 2000 RPM maximum?

The aluminium-and-copper heatsink is limited to 37 CFM airflow, so sustained loads hit the cooler’s dissipation ceiling before the 28 dBA noise ceiling.

How much noise and heat does the 4-pin ARGB fan produce at full 2000 RPM in a small-form-factor case?

At 2000 RPM the fan reaches 28 dBA maximum and moves 37 CFM; the 60 mm height keeps exhaust heat inside compact chassis airflow paths.
