CPU-køler Jonsbo CR-1300 EVO 90mm sort — luftkøler, 90-mm-blæser

The Jonsbo CR-1300 EVO is a compact CPU air cooler with a 90 mm fan in a black finish designed for space-constrained desktop builds. It provides targeted air cooling for mainstream processors in small form factor (SFF) and conventional ATX cases, aiming to lower CPU temperatures and maintain quieter operation compared with many stock coolers.

Advantages

The cooler’s compact tower and 90 mm fan deliver a balance of airflow and low noise suitable for compact systems. Its black finish allows consistent aesthetics in dark-themed builds. The design focuses on reducing CPU temperature under sustained loads while minimizing fan noise, supporting improved system stability and consistent processor performance.

Suitable for

• Small form factor desktop PCs where clearance is limited
• Mainstream processors with moderate heat output
• Systems where a quieter alternative to stock coolers is preferred
• Builds requiring a low-profile or compact tower cooler

When it may not be suitable

This compact 90 mm cooler may not be suitable for high TDP enthusiast or overclocked CPUs that require large heatsinks or multiple heat pipes for heavy sustained cooling. Users seeking the absolute lowest temperatures under extreme loads should consider larger air coolers or liquid cooling solutions.

Key specifications

• Cooling type: air cooler with 90 mm axial fan
• Fan size: 90 mm
• Color: black
• Compatibility: designed for typical desktop CPU sockets in SFF and ATX cases (check motherboard and case clearance)
• Intended use: CPU cooling for mainstream desktop processors

How to use

Install the cooler on a compatible CPU socket following motherboard and case clearance checks. Secure the cooler to the CPU socket according to the mounting hardware provided by the manufacturer and apply an appropriate amount of thermal paste between the CPU heat spreader and the cooler base. Connect the fan cable to the CPU fan header on the motherboard and configure fan control in BIOS or via software to balance cooling and noise levels. Verify clearances around RAM modules and tall components before final assembly.

What to consider before purchase

• Case clearance for cooler height and surrounding components
• Socket compatibility with your motherboard
• Target CPU thermal design power (TDP) and cooling requirements
• Desired balance between noise level and cooling performance

Recommendations

For typical desktop processors in compact builds, set a moderate fan curve to maintain lower noise at idle and increase fan speed under load. Ensure good case airflow with at least one intake and one exhaust fan to help the 90 mm cooler perform effectively.
