Low-profile Intel cooler for 95W CPUs

The Cooler Master i70C ARGB is a 70mm-tall air cooler built for Intel LGA 1700 and LGA 1851 sockets. It targets small-form-factor builders who need to cool a 95W TDP processor without exceeding tight case clearances. A 120mm PWM fan with rifle bearing spins between 650 and 1800 RPM to move up to 37.08 CFM. The unit weighs 406g and includes the LGA 1700 install kit.

95W thermal limit and 28 dBA noise ceiling

The aluminium heatsink with copper insert is rated for 95W TDP, so processors beyond that envelope will throttle or overheat. Fan speed tops out at 1800 RPM with a maximum noise level of 28 dBA, limiting acoustic headroom in silent builds. Addressable RGB lighting uses a 3-pin 5V header and is certified to sync with Asus AURA, Gigabyte RGB Fusion, MSI Mystic Light and ASRock RGB LED. The 4-pin PWM connector provides standard speed control.

Check 70mm clearance and 5V ARGB header

Verify that your chassis allows at least 70mm of cooler height from the motherboard surface to the side panel. Confirm the board has a 5V 3-pin ARGB header if you want lighting control; otherwise the LEDs will remain at default behaviour. Ensure the CPU socket is LGA 1700 or LGA 1851, as the supplied mounting hardware does not support other platforms. The 120mm fan occupies 120.00 x 120.00 x 25.00 mm, so check for RAM or VRM heatsink interference.

Questions about this item

Should I pick the 70 mm height version or a taller cooler for my case?

This cooler is 70 mm tall, so it fits cases that limit CPU cooler height to 70 mm; if your case allows more clearance you could consider a taller model, but this is the only height offered for the i70C.

What does the 95 W TDP rating mean when the cooler is installed?

The 95 W TDP rating indicates the maximum heat load the aluminum fins and copper insert are designed to dissipate under typical workloads.

Does the 4‑pin PWM connector limit fan speed control on my motherboard?

The 4‑pin PWM connector lets the motherboard vary the fan between 650 and 1800 RPM, so speed control is handled by the board’s PWM header, not capped by the cooler itself.
