CPU-jäähdytin Jonsbo CR-1400 EVO 140 mm tuulettimella ja 4 lämpöputkella

Jonsbo CR-1400 EVO is an air CPU cooler with a single 140 mm fan and four heat pipes designed for desktop tower builds. The cooler uses direct-contact heat pipes that improve thermal transfer from the processor heat spreader to the aluminium fin stack. A 140 mm fan provides balanced airflow to move heat through the fins while keeping acoustic levels moderate. The unit is intended for mainstream desktop processors and supports typical use in gaming, content creation and office productivity systems.

Advantages

The cooler combines four copper heat pipes with a dense aluminium fin array to increase the surface area for heat dissipation while the direct-contact arrangement reduces thermal resistance. The 140 mm fan offers a larger blade area compared with 120 mm designs, enabling similar or better airflow at lower RPM and reduced noise. The tower form factor fits most standard ATX and micro-ATX cases and is compatible with common CPU socket types. Overall, the design focuses on effective heat transfer and quiet operation in everyday desktop scenarios.

Suitable for

• Mainstream desktop CPUs in standard tower PC cases
• Gaming systems requiring stable temperatures under load
• Workstations for productivity and light content creation
• Silent or low-noise builds where moderate cooling is sufficient

Key specifications

• Cooling method: air cooling with heat pipes and fin stack
• Fan size: 140 mm
• Heat pipes: four direct-contact heat pipes
• Compatibility: tower cooler for standard ATX and micro-ATX cases
• Construction materials: copper heat pipes, aluminium fins
• Airflow/noise balance: larger fan diameter for lower RPM operation

How to use

Install the cooler following the motherboard and case manufacturer's instructions: secure the mounting bracket to the CPU socket, apply an appropriate amount of thermal paste to the processor heat spreader, position the cooler so the heat pipes make direct contact and fasten the cooler evenly to the bracket. Connect the 140 mm fan to a CPU fan header or a compatible fan controller to allow PWM or voltage-based speed control. Ensure clearance for RAM modules and case panels before final assembly, and verify fan rotation and airflow direction after boot.

Recommendations

For best results, use a high-quality, thin spread of thermal compound and ensure even mounting pressure so the direct-contact heat pipes sit flush with the CPU surface. Configure fan speed profiles in BIOS or using software to balance cooling and noise according to workload. Periodically clean dust from the fan and fins to maintain airflow and thermal performance.
