Cooler Master RR-I7C7 LGA1700 ARGB CPU Cooler

Name: Cooler Master RR-I7C7 LGA1700 ARGB CPU Cooler
Brand: Cooler Master
SKU: RR-I7C7-18PA-R1

Overview

The Cooler Master i70C (RR-I7C7-18PA-R1) is a low-profile CPU air cooler purpose-built for Intel's LGA 1700 and LGA 1851 platforms. Standing just 70mm tall, it is specifically designed for compact and slim desktop builds where standard tower coolers simply do not fit. The heatsink pairs anodized black aluminum fins with a copper insert at the base, allowing for more efficient heat transfer from the CPU's integrated heat spreader into the fin array than a purely aluminum design would provide. This combination is rated to handle processors with a thermal design power of up to 95W, covering Intel Core i3 and Core i5 chips comfortably.

Cooling is handled by a 120mm PWM fan that operates between 650 and 1,800 RPM, connected via a standard 4-pin header for automatic speed control based on CPU temperature. The fan blades feature a frosted surface treatment that disperses the built-in ARGB lighting more uniformly, creating a smooth glow rather than distinct LED hotspots. The ARGB output connects through a 3-pin header and is compatible with Asus Aura Sync, Gigabyte RGB Fusion, MSI Mystic Light, and ASRock RGB LED software for synchronized lighting across your build. Installation uses Cooler Master's redesigned bracket system that mounts directly to LGA 1700 and LGA 1851 boards without requiring a backplate, keeping the process straightforward even in tight cases.

Key Features

Minimalist Revamped: Anodized Black Aluminum fins aesthetic brings a renewed vibe while keeping its minimalistic essence.

Cool for i | U Series: Aluminum fins paired with a copper insert base ensure optimal cooling for Intel 3 | 5.

Copper Insert: Copper insert deliver efficient heat dissipation for a 95W TDP CPU.

Dynamic PWM Fan: A PWM 4-pin header allows adjustable fan speeds from 650 to 1,800 RPM, to balance noise and airflow.

Frosted Blade Design: The frosted blade enhances the dispersion of aRGB lighting, creating a vibrant and customizable luminous effect.

Simplified Brackets: Redesigned brackets simplify installation on LGA 1700|1851 platforms.

Versatile Compatibility: 70mm tall design offers performance for low-profile chassis compatibility.

Pros & Cons

👍 Pros

Ultra-low 70mm profile height fits in slim and small form factor cases where tower coolers are too tall
Copper insert in the base improves heat transfer compared to all-aluminum designs at this price point
120mm PWM fan with 650–1,800 RPM range allows flexible noise-to-airflow tuning
Frosted fan blade design diffuses ARGB lighting evenly for a cleaner visual effect
Redesigned mounting brackets simplify installation on LGA 1700 and LGA 1851 without backplate hassle

👎 Cons

95W TDP limit restricts use to mid-range Intel processors—not suitable for Core i7 or i9 chips under heavy load
Only supports Intel LGA 1700 and LGA 1851, excluding all AMD platforms and older Intel sockets
Low-profile aluminum fin stack offers less thermal mass than tower-style coolers, limiting overclocking headroom
Single-fan design with no heatpipe means thermal performance plateaus quickly under sustained workloads

Frequently Asked Questions

Which CPU sockets does the Cooler Master i70C support?

The i70C is compatible with Intel LGA 1700 and LGA 1851 sockets. It is designed specifically for these platforms and does not support AMD sockets or older Intel socket types.

What is the maximum TDP this cooler can handle?

The i70C is rated for CPUs with a thermal design power (TDP) of up to 95W, making it suitable for Intel Core i3 and Core i5 processors in the LGA1700 and LGA1851 families.

How tall is this cooler, and will it fit in a small form factor case?

The cooler stands just 70mm tall, making it a low-profile design that fits in compact mini-ITX and slim desktop cases where standard tower coolers cannot be used.

Is the ARGB lighting compatible with motherboard RGB software?

Yes. The i70C uses a standard 3-pin ARGB header and is compatible with Asus Aura Sync, Gigabyte RGB Fusion, MSI Mystic Light, and ASRock RGB LED for synchronized lighting control.

Does the cooler come with thermal paste pre-applied?

Cooler Master typically includes thermal compound either pre-applied to the base or as a separate tube in the box. Check the packaging contents for your specific unit.
