Cooler Thermaltake NIC C4 Processor Cooler 12 cm

Thermaltake NiC C4 Untouchable CPU Cooler is a tower-style air cooler designed to provide high cooling performance while avoiding interference with memory modules and motherboard components. The cooler uses a nickel-plated copper base, four U-shaped heat pipes, curved aluminum fins and dual 120 mm fans with an adjustable speed control to support overclocked systems and maintain compatibility with tall RAM modules.

Advantages

The NiC C4 provides a non-interference layout that allows installation of tall or overclocked RAM without removing cooling components. Its nickel-coated copper base combined with four 6 mm U-shaped heat pipes and a large fin array ensures effective heat transfer for CPUs up to 200 W TDP. Dual 120 mm fans on a tool-less bracket and an adjustable speed knob let you balance airflow and noise between 1000 and 2000 RPM.

Suitable for

• High-performance desktop builds with overclocked CPUs (up to 200 W thermal load)
• Systems using tall or densely populated RAM modules
• Compact mid-tower and full-tower cases where a 120 mm fan cooler fits
• Users who want manual fan speed adjustment for noise/performance trade-offs

Key specifications

• Fan diameter: 120 mm

• Maximum air pressure: 2.99 mmH2O
• Rated voltage: 12 V
• Heat pipes: 4 × 6 mm U-shaped
• Base: nickel-plated copper
• Fins: curved aluminum fins, 0.4 mm thickness
• Weight: 0.794 kg
• Dimensions (fan): 120 × 120 × 25 mm
• Supported sockets: Intel and AMD mainstream sockets including legacy AM2/AM2+/AM3/AM3+/FM1/FM2

How to use

Mount the NiC C4 using the included all-in-one backplate and mounting hardware compatible with supported Intel and AMD sockets. Position the cooler so airflow runs through the curved fin stack toward the case exhaust, attach the dual 120 mm fans onto the tool-less bracket, and connect the fan power to a 4-pin PWM header or appropriate fan connector. Adjust the fan speed using the integrated knob to obtain the desired balance of cooling and noise.

Recommendations

For best results, ensure adequate case airflow and confirm RAM clearance before final installation. Use moderate fan speeds for everyday operation and increase RPM when performing sustained CPU-intensive tasks or overclocking to maintain safe temperatures.
