CPU chladič PCCOOLER GI-R66U 120 mm ventilátor, 1000 ot/min, tichý vzduchový chladič

PCCOOLER GI-R66U is a compact air CPU cooler with a 120 mm fan that rotates at 1000 RPM. It is designed for basic thermal management in desktop systems, offering a balance of airflow and low acoustic output. The cooler is suitable as a direct replacement for many stock coolers or as a modest upgrade to improve processor temperatures during everyday office and home use.

Advantages

The GI-R66U combines a 120 mm low-speed fan with a streamlined heatsink to deliver quieter operation compared with higher-RPM solutions while maintaining adequate cooling for mainstream CPUs under light to moderate loads. Its simple design supports easy installation and compatibility with common tower cases, and the low-noise profile makes it appropriate for noise-sensitive environments such as home offices.

Suitable for

• Office PCs and home desktops with light to moderate CPU workloads
• Replacing factory stock coolers for improved acoustics and marginal temperature gains
• Builds where low fan noise is a priority
• Systems with limited airflow requirements that fit a 120 mm cooler footprint

Key specifications

• Fan size: 120 mm
• Fan speed: 1000 RPM (nominal)
• Cooling type: air cooler with heatsink and axial fan
• Acoustic profile: low-noise operation at rated speed
• Compatibility: designed for standard desktop CPU sockets (physical mounting depends on motherboard and case)

How to use

Before installation, power down the PC and disconnect from mains. Remove the existing cooler and clean any thermal compound residue from the CPU surface. Apply a thin, even layer of thermal paste to the CPU; align the GI-R66U cooler over mounting holes and secure it according to the motherboard mounting hardware. Reconnect the fan header to the CPU_FAN or SYS_FAN header on the motherboard and ensure the fan spins at the expected low RPM during initial power-up. Monitor CPU temperatures during the first boot and under typical workloads to confirm adequate cooling and proper fan operation.

Recommendations

The cooler is intended for office and home use with standard processors; do not rely on it for sustained heavy workloads or overclocking. Maintain case airflow by keeping intake and exhaust vents clear, and periodically clean dust from the fan and heatsink fins to preserve cooling performance and low noise levels.
