Hyper 620S dual-tower air cooler

The Cooler Master Hyper 620S is a dual-tower air cooler with six copper direct-contact heat pipes and a single 120 mm PWM fan. It targets builders who want strong thermal headroom for mainstream CPUs while keeping case clearance generous. ARGB lighting syncs automatically or through a 3-pin header. The nickel-plated finish adds corrosion resistance and a clean look.

Socket and height check before ordering

Verify that your motherboard uses one of the listed sockets: AM4, AM5, LGA 1150, 1151, 1155, 1156, 1200, 1700 or 1851. Confirm your chassis can accept a cooler up to 154.9 mm tall. Ensure a 4-pin PWM header is available for fan control and a 3-pin 5 V ARGB header if you want full lighting customisation. The upgraded brackets simplify mounting on current AM5 and LGA 1700 platforms.

Thermals, noise and power in normal use

The 120 mm rifle-bearing fan spins between 650 and 1750 RPM, moving 71.93 CFM at a maximum of 27.2 dB(A). Dual towers double the fin surface area for efficient heat dissipation under typical loads. PWM control lets the fan ramp only when needed, keeping idle noise low. Power draw is limited to the 4-pin header rating, so no extra cabling is required.

Questions about this item

Does the Hyper 620S box include thermal paste and a second 120mm fan, or must I buy them separately?

The package contains the dual-tower heatsink, one pre-installed 120mm PWM fan with addressable RGB, mounting brackets for AMD AM5/AM4 and Intel LGA 1851/1700/1200/1151/1150/1155/1156, and a tube of thermal paste. A second fan is not included but can be added using the supplied fan clips.

Should I choose the single-fan Hyper 620S or look for a dual-fan version for my Ryzen build?

This model is sold only in the single-fan configuration. The 120mm PWM fan runs at 650–1750 RPM delivering 71.93 CFM at 27.2 dB(A). Adding a matching second fan is optional and uses the same clips, but no dual-fan SKU exists for the Hyper 620S.

What does the 154.9 mm height figure mean for fitting the Hyper 620S inside my case?

The cooler stands 154.9 mm tall, so your chassis must list a CPU-cooler clearance of at least that figure. Measure from the motherboard surface to the side-panel window; if the case spec is 155 mm or more the Hyper 620S will fit without interfering with the glass or door.
