Processor Cooler Thermalright Le Grand Macho RT — 15 cm Fan, 300–1300 RPM, 125 m³/h, Black/White

The Thermalright Le Grand Macho RT is an active version of the semi-passive Le Grand Macho cooler, combining a large nickel-plated copper base, seven 6 mm heat pipes and an optimized fin stack with an included temperature-controlled TY-147 B PWM fan. The cooler is designed for high-performance desktop processors and offers a compact footprint (152 x 147 x 159 mm) while supporting broad Intel and AMD socket compatibility. The TY-147 B fan uses a fluid dynamic bearing and side-vent design to reduce noise while delivering up to 125 m³/h airflow and a maximum active cooling capability of approximately 280 TDP.

Advantages

The cooler pairs a high-gloss, slightly convex nickel-plated C1100 copper base with seven tightly integrated 6 mm heat pipes to maximize heat transfer from the CPU to the fin array. The TY-147 B PWM fan provides a wide RPM range (300–1300 RPM) with low noise (about 14–20 dB(A)) and optimized side vents for quieter operation. Perforated aluminum fins, a low-air-resistance fin design and a central oval air duct improve airflow distribution and reduce turbulence hot spots. The cooler includes a universal mounting kit, an extra-long magnetic screwdriver for easier installation and a syringe of Thermalright Chill Factor 3 thermal paste.

Suitable for

• High-performance desktop CPUs, including multi-core Intel Core and AMD processors
• Systems requiring quiet active cooling with a 140–150 mm class fan profile
• PC builds where a polished nickel-plated base and mature heat-pipe technology are preferred for thermal efficiency

Когда может быть не подходящим

Из-за высоты 159 мм и ширины 152 мм кулер может не подходить для компактных корпусов с ограниченным пространством вокруг процессорного разъёма или высокими модулями оперативной памяти, которые перекрывают область монтажа вентилятора. Также при установке на новые Intel LGA1151 («Skylake») рекомендуется использовать специальную опорную прокладку 1151 для обеспечения корректной установки.

Key specifications

• Overall dimensions: 152 x 147 x 159 mm (W x D x H)
• Fan diameter: approximately 150 mm (TY-147 B)
• Fan speed: 300–1300 RPM (PWM)
• Airflow: up to 125 m³/h
• Noise level: ~14–20 dB(A)
• Heat pipes: 7 × 6 mm copper heat pipes
• Base: nickel-plated polished C1100 copper, slightly convex contact surface
• Fin material: perforated aluminum fins with oval central air duct
• Active cooling rating: about 280 TDP

How to use

Install the cooler using the included universal mounting kit that supports current Intel and AMD sockets. Apply a thin, even layer of the supplied Thermalright Chill Factor 3 thermal paste to the CPU heatspreader, position the cooler so the convex copper base contacts the CPU, and secure it with the provided mounting hardware. Fit the TY-147 B PWM fan to the heatsink using the revised fan brackets and adhesive anti-vibration pads for decoupled mounting. Connect the fan to a PWM-capable CPU fan header to allow automatic speed control based on temperature.

What to consider before purchase

• Check case clearance for cooler height (159 mm) and motherboard clearance for RAM modules near the CPU socket.
• Verify compatibility with your CPU socket and whether an optional LGA1151 support spacer is needed for Skylake systems.
• Confirm available fan header is PWM-capable to use automatic fan speed control.

Usage recommendations

For best results, mount the cooler so airflow follows your case’s front-to-rear or bottom-to-top path, ensure unobstructed intake/exhaust airflow, and use the included magnetic screwdriver to tighten fasteners evenly. Request the free 1151 support spacer from the manufacturer when installing on LGA1151 Skylake CPUs.
