PCCooler RZ620

Manufacturer: PCCooler

The PCCooler RZ620 is a dual-fan air CPU cooler designed to fit a wide range of modern and previous-generation platforms, including Intel's LGA 1851, LGA 1700, and LGA 1200, as well as AMD's AM4 and AM5 sockets. It uses a tower heatsink form factor with fluid dynamic bearings on both fans, which generally contribute to quieter and longer-lasting operation compared to sleeve bearing alternatives. Thermal paste is included in the package, and the cooler carries a 3-year warranty.

The RZ620 measures 157.5 mm tall, 142.5 mm wide, and 130 mm deep, with a total weight of 1,400 g. Its two fans spin at up to 2,000 RPM and together push a maximum airflow of 86.73 CFM, with audible noise ranging from 16 dB at the low end to 32 dB at full speed. The cooler does not include RGB lighting or an integrated display, keeping its feature set focused on thermal performance rather than aesthetics.

Pros
  • Compatibility spans eight CPU sockets across both Intel and AMD platforms, including LGA 1851, LGA 1700, AM4, and AM5, making it usable across a wide range of current and previous-generation builds.
  • Fluid dynamic bearings on the fans support quieter and more durable long-term operation compared to simpler bearing types.
  • Thermal paste is included in the box, removing the need for a separate purchase before installation.
  • The minimum noise level of 16 dB at low fan speeds makes it unobtrusive during light workloads or idle operation.
  • A 3-year warranty provides a reasonable coverage period for a cooling product of this type.
Cons
  • At 1,400 g, the cooler is relatively heavy, which may place strain on motherboard mounting points in certain cases or orientations.
  • The heatsink stands 157.5 mm tall, which may cause clearance issues in smaller or mid-tower cases with limited CPU cooler height support.
  • Maximum fan noise reaches 32 dB at full speed, which may be noticeable in quiet environments during sustained high-load operation.
  • There is no RGB lighting for users who want their cooling solution to integrate with an illuminated build aesthetic.
Who is this for?

The RZ620 is well-matched to builders who want broad platform compatibility without swapping coolers between upgrades, given its support for eight CPU sockets spanning both Intel and AMD platforms including LGA 1700, LGA 1851, AM4, and AM5. Its dual fans with fluid dynamic bearings and a minimum noise output of 16 dB make it a reasonable fit for users who prioritize quieter operation during everyday or light workloads. The inclusion of thermal paste and a 3-year warranty also suits those who want a complete, low-hassle installation experience without sourcing additional materials.

Who is this NOT for?

Users building in compact or small-form-factor cases should verify clearance carefully, as the 157.5 mm heatsink height may exceed the CPU cooler limits of tighter enclosures. At 1,400 g, the cooler's weight could also be a concern for builds where motherboard flex or transport stress is a consideration. Additionally, users who want their system to feature a visually coordinated, illuminated interior will find this cooler unsuitable, as it has no RGB lighting and no integrated display — its design is entirely functional with no aesthetic additions.

Cooling:

Cooling type Air
Max fan RPM 2000 rpm
Max airflow 86.73 CFM
Number of fans 2

The RZ620 uses air cooling as its method of heat dissipation, relying on two fans to move air through the heatsink. Those fans spin at up to 2,000 RPM and together deliver a maximum airflow of 86.73 CFM, providing the airflow capacity needed to handle the thermal output of compatible processors.

Dimensions:

Heatsink/water block height 157.5 mm
Heatsink/water block width 142.5 mm
Heatsink/water block depth 130 mm

The RZ620 heatsink measures 157.5 mm in height, 142.5 mm in width, and 130 mm in depth, giving it a sizeable tower profile that users should verify against their PC case clearance specifications before installation.

General info:

CPU socket LGA 1851, LGA 1700, LGA 1200, LGA 1151, LGA 1150, LGA 1155, AM4, AM5
Audible noise (min) 16 dB
Audible noise (max) 32 dB
weight 1400 g
warranty period 3 years

The RZ620 is compatible with a broad range of CPU sockets, covering Intel's LGA 1851, LGA 1700, LGA 1200, LGA 1151, LGA 1150, and LGA 1155, as well as AMD's AM4 and AM5 platforms, making it suitable for a wide variety of current and previous-generation builds. Audible noise levels range from 16 dB at minimum fan speed to 32 dB at full load, keeping acoustic output relatively contained across its operating range. The cooler weighs 1,400 g and is backed by a 3-year warranty.

Features:

Fan bearings Fluid dynamic bearings
has RGB lighting ✕
Thermal paste Included
Has a display ✕

The RZ620 fans use fluid dynamic bearings, which tend to support quieter operation and extended longevity over the fan's lifespan. Thermal paste is included in the package, so no separate purchase is needed for initial installation. The cooler does not feature RGB lighting or an integrated display, reflecting a purely functional design approach without decorative additions.

Final Verdict

The PCCooler RZ620 is a straightforward air CPU cooler that covers the essentials well — broad socket compatibility across eight Intel and AMD platforms, fluid dynamic bearing fans, and a noise floor of 16 dB that keeps it unobtrusive during lighter workloads. Its dual-fan configuration delivering up to 86.73 CFM gives it solid airflow capacity, and the inclusion of thermal paste alongside a 3-year warranty makes for a complete out-of-box experience. Users should be mindful of its 157.5 mm height and 1,400 g weight when selecting a case, and those seeking RGB aesthetics will need to look elsewhere. For builders prioritizing platform versatility and functional, no-frills cooling across a wide range of ATX or mid-tower builds, the RZ620 presents a well-rounded and dependable option.
