Scythe Shuriken 3

Manufacturer: Scythe

The Scythe Shuriken 3 is a compact air CPU cooler designed for systems where vertical clearance is a constraint. Its notably slim heatsink, standing at just 39 mm tall, makes it a practical option for small form factor builds without requiring liquid cooling infrastructure. The unit ships with thermal paste included and carries a 2-year warranty.

Cooling is handled by a single fan capable of spinning up to 2500 rpm, delivering a maximum airflow of 36.45 CFM with noise levels ranging from 1.8 dB at the low end to 31.78 dB at full speed. The fan runs on fluid dynamic bearings, which generally contribute to smoother and quieter long-term operation. The heatsink body measures 92 mm wide and 94.4 mm deep, and the cooler as a whole weighs 320 g. Socket compatibility covers a broad range of Intel and AMD platforms, including LGA 1851, AM4, and AM5, alongside LGA 1200, LGA 1155, LGA 1151, and LGA 1150. RGB lighting is not featured on this model.

Pros
  • Fluid dynamic bearings on the fan contribute to smoother and quieter operation over time
  • Minimum noise level of 1.8 dB makes it suitable for near-silent use cases at low loads
  • Compatible with a wide range of sockets including AM4, AM5, LGA 1851, LGA 1200, LGA 1155, LGA 1151, and LGA 1150
  • Thermal paste is included, allowing for immediate installation without additional purchases
  • At 39 mm in height, the heatsink fits in chassis with tight vertical clearance restrictions
Cons
  • Maximum noise level of 31.78 dB at full fan speed is relatively noticeable under load
  • Single fan configuration offers no redundancy if the fan fails
  • No RGB lighting for users who prefer visual customization in their build
  • Maximum airflow of 36.45 CFM is modest, which may limit cooling headroom under sustained heavy loads
  • Warranty period is limited to 2 years
Who is this for?

The Scythe Shuriken 3 is well suited to small form factor and compact builds where vertical clearance is limited, given its 39 mm heatsink height. Users who prioritize quiet system operation will also find it a practical fit, as its minimum noise output of 1.8 dB means the fan is nearly inaudible at lower speeds. Its broad socket compatibility — spanning AM4, AM5, LGA 1851, LGA 1200, and several older Intel platforms — makes it a reasonable choice for builders working across a variety of Intel and AMD systems who need a straightforward, low-profile air cooling solution.

Who is this NOT for?

This cooler is not well suited for users running thermally demanding workloads that require sustained heavy cooling, as the single fan and maximum airflow of 36.45 CFM offer limited thermal headroom under prolonged load. Those who expect near-silent operation at full speed may also be disappointed, since noise levels can reach 31.78 dB when the fan runs at its 2500 rpm ceiling. Additionally, builders looking to incorporate RGB lighting as part of a visually coordinated setup will need to look elsewhere, as this model does not include any lighting features.

Cooling:

Cooling type Air
Max fan RPM 2500 rpm
Max airflow 36.45 CFM
Number of fans 1

The Scythe Shuriken 3 uses air cooling and is equipped with a single fan that spins up to 2500 rpm, producing a maximum airflow of 36.45 CFM. This setup provides a straightforward, self-contained cooling solution without any liquid components or additional fan configurations.

Dimensions:

Heatsink/water block height 39 mm
Heatsink/water block width 92 mm
Heatsink/water block depth 94.4 mm

The heatsink on the Scythe Shuriken 3 measures 39 mm in height, 92 mm in width, and 94.4 mm in depth, giving it a compact overall footprint that reflects its low-profile design intent.

General info:

CPU socket LGA 1150, LGA 1151, LGA 1155, AM4, LGA 1851, LGA 1200, AM5
Audible noise (min) 1.8 dB
Audible noise (max) 31.78 dB

The Scythe Shuriken 3 is compatible with a wide range of CPU sockets, covering LGA 1150, LGA 1151, LGA 1155, LGA 1200, LGA 1851, AM4, and AM5, making it suitable for a broad selection of Intel and AMD platforms. Audible noise ranges from 1.8 dB at its quietest to 31.78 dB at full load, and the unit weighs 320 g in total. A 2-year warranty is included with the cooler.

Features:

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

The fan on the Scythe Shuriken 3 uses fluid dynamic bearings, and thermal paste is included in the package, so no separate purchase is needed before installation. The cooler does not feature RGB lighting or an integrated display.

Final Verdict

The Scythe Shuriken 3 is a purposefully designed low-profile air cooler that delivers where its specifications promise — specifically in compact, space-constrained builds that demand a slim heatsink profile without sacrificing broad platform compatibility. Its fluid dynamic bearing fan, near-silent low-end noise floor, and wide socket support across current and legacy Intel and AMD platforms give it a well-rounded foundation for the use cases it targets. That said, users with higher thermal demands or a preference for whisper-quiet operation at sustained loads should weigh its modest airflow ceiling and single-fan configuration carefully. For small form factor builders who need a reliable, no-frills cooling solution with a straightforward installation experience, the Scythe Shuriken 3 represents a coherent and well-specified option within its category.
