This article takes a deep look at the Hyper 620S, a dual-tower model in Cooler Master's "Hyper" CPU cooler series, based on what Cooler Master's official Japanese product page states.

## Overview

The official model number of the Hyper 620S is RR-D6NA-17PA-R1. Its cooler type is listed as "空冷CPUクーラー" (air CPU cooler), its product series as "Hyper", and its colour as "ブラック/シルバー" (black/silver). In the page's introduction, Cooler Master says the Hyper 620S "Hyper シリーズの伝統をさらに進化させます" (carries the Hyper series tradition further).

The heatsink is listed as "6 Heat Pipes / Aluminum Fins", with six heat pipes. The fan quantity is "2 個" (two fans) and the fan profile is "アドレサブルRGB" (addressable RGB). The page's feature headings describe the heatsink as "デュアルタワーヒートシンク" (dual-tower heatsink), so this is a dual-tower air cooler with lit fans.

The official height is 154.9 mm, and the official socket entries are "Intel® LGA 1851 / 1700 / 1200 / 1151 / 1150 / 1155 / 1156 socket" and "AMD® AM5 / AM4 Socket". The short version: the reasons to pick it are the low height that the page calls "コンパクトな高さ" (compact height) and a socket list that covers both Intel and AMD widely.

## Compatibility Guide

These are the fit checks that follow from the official spec table.

**Intel sockets:** The official entry is "Intel® LGA 1851 / 1700 / 1200 / 1151 / 1150 / 1155 / 1156 socket". LGA 1851 is on the list.

**AMD sockets:** The official entry is "AMD® AM5 / AM4 Socket".

**Height versus your case:** The product dimensions (L x W x H) are "125 x 137 x 154.9 mm". Under "コンパクトな高さ" (compact height), the page says "低背設計のヒートパイプと全高154.9mmにより、ほとんどのケースに対応します" (low-profile heat pipes and a 154.9mm overall height, for most cases). Check that your case's CPU cooler height limit is above this height.

**Depth and width:** The product length (L) and width (W) are the values to use when checking the position against the memory slots and any fans or radiator at the top of the case. If you mount fans or a radiator at the top of the case, compare this length and width with the space between the top edge of the motherboard and the case roof. Check the installed orientation in the installation drawing in the manual.

**Fan size:** The fan dimensions (L x W x H) are "120 x 120 x 25mm".

**Connecting to the motherboard:** The fan connector is "4-Pin (PWM)". Check how many CPU fan headers your board has, or how you will connect the fans. Check the manual for the included cables and the lighting connector.

## Product Info

Here are the fan-related official values, with what each one means for a buyer.

- **Fan speed:** The official entry is "650-1750 RPM" with a tolerance of ± 10 per cent attached.
- **Airflow:** 122 m³/h (最大, maximum). It is a maximum, not the airflow at reduced speed.
- **Static pressure:** 1.86 mmH₂O (最大, maximum). This indicates how hard the fans can push air through the fin stack, again as a maximum.
- **Noise:** Listed as 27.2 dBA.
- **Bearing:** ライフルベアリング (rifle bearing).
- **Fan life (MTTF):** Listed as ">160,000 時間" (hours). MTTF (mean time to failure) is a measure of the average time before a failure.
- **Electrical values:** Rated voltage 12 VDC, rated current 0.26A, safety current 0.37A, power consumption 3.12W. These help when planning the load on your motherboard's fan headers. The rated voltage of 12 VDC means the fans run on 12 V direct current.

**Warranty:** The manufacturer warranty is listed as two years (2 年).

**Spec sheet:** Besides the spec table, the official page offers a "製品仕様書" (product spec sheet) download.

## Two Fans and Six Heat Pipes

On the official spec table, the fan quantity is "2 個" and the heat pipe count is "6". The page's feature headings call the heatsink "デュアルタワーヒートシンク" (dual-tower heatsink). Check the fan mounting positions in the manual's drawings.

Heat pipes carry the heat from the CPU into the heatsink, and the fins are aluminium (Aluminum Fins). On heat transfer, the page's description says "ニッケルメッキ仕上げのベースを全面に施した均一なヒートパイプにより、ムラのない効率的な熱伝導を実現します" (uniform heat pipes with a nickel-plated base finish across the whole surface give even, efficient heat transfer). The feature list also has an item called "高性能Cryofuze" (high-performance Cryofuze), described as using nanoparticles for excellent thermal conductivity.

The fan profile is addressable RGB, so the fans light up. Under the heading "自動ARGB" (auto ARGB), the page says that intelligent LED detection provides the default ARGB spectrum lighting automatically. In other words, the page says the default spectrum lighting is provided automatically. For changing colours and effects yourself, the page mentions "カスタマイズ可能でコントロールできるARGBライト" (customisable, controllable ARGB lighting) for a style of your own. Check the manual for how to connect it for control.

## Reading the Socket List

The official spec table lists the supported sockets on two lines, Intel and AMD. The Intel line has seven sockets: LGA 1851, 1700, 1200, 1151, 1150, 1155 and 1156. The AMD line has two: AM5 and AM4.

Check that your motherboard's socket is on the list, then check the mounting hardware and installation steps for that socket in the manual.

## Planning the Fit from the Dimensions and Fan Values

When fitting it into a case, compare the product height with the case's CPU cooler height limit, and use the length and width to check the position against parts around the socket and any fans at the top of the case.

The airflow and static pressure figures are both listed as maximums. The fans use a PWM-type connector, and the speed is given as a range. If quiet operation matters, look for information on noise in real use from the retailer or other sources.

If you plan to connect the fans to a single header, check the header's current limit in your motherboard's specifications. The fans' current values are under "Electrical values" in Product Info.

## Best Use Cases

- **Choosing a cooler that works with Intel or AMD.** The official socket list covers both an Intel line and an AMD line.
- **Lighting up the inside of the case.** With addressable RGB fans, it is easy to match a build where the lighting is coordinated.
- **Comparing fans by their listed values.** Airflow, static pressure, noise, bearing, fan life and the electrical values are all on the spec table. How to read each one is set out in Product Info.

## Things to Consider

Here is what to check before buying, following the official values.

First, your case's CPU cooler height limit. Compare the product height with your case's limit. If the margin is small, allow for the side glass and cable thickness as well.

Second, the position relative to your memory. If you use memory with tall heat spreaders, use the product length and width to check the position against the memory slots in the maker's official spec table or the manual.

Third, fan wiring. The cooler comes with two fans, so make sure you have enough CPU fan headers.

Fourth, the lighting connection. The fan profile is addressable RGB, and the page's "自動ARGB" description says the default lighting is provided automatically. To change colours and effects yourself, confirm the matching header on your motherboard in the manual or similar documentation.

On the warranty, the official spec table gives the manufacturer warranty period. Keep your purchase records and check the warranty terms on Cooler Master's support information.

Finally, the model number on the listing. The official model number is RR-D6NA-17PA-R1. Make sure the store listing shows the same model number. See the maker's official spec table for full details.
