Symphony Lighting, Four Heat Pipe Single Tower Radiator | Jonsbo CR-1000 EVO unpacking

The Jonsbo CR-1000 EVO is a single-tower, single-fan radiator, equipped with four heat pipes. It features a captivating carbon fiber texture and is paired with a distinctive color fan for an appealing aesthetic appeal.

The CR-1000 EVO is compatible with popular Intel LGA 1700/1200/115X and AMD AM4/AM5 platforms. Its offset design ensures no interference with the memory modules, thereby providing an enhanced display of the memory.

The CR-1000 EVO comes in two color variants, black and white. The top cover, fan, and wires all match the selected color, while the body of the radiator boasts a nickel-plated silver finish. Its CPU contact surface features a direct heat pipe contact design for efficient heat dissipation. Furthermore, its tower body is offset to prevent obstruction of the memory, thereby enhancing its compatibility.

With a fan speed range of 600-1500RPM, the CR-1000 EVO uses a 4Pin PWM connector. It does not come with an additional connector for lighting power, meaning the light cannot be adjusted or switched off. However, this simplifies the process for users, as there is no need for motherboard light control support. The lighting on the top cover also uses a 4Pin PWM connector and can be connected in series with the fan using just one wire. In practice, this setup offers commendable performance in terms of airflow and noise control.

CR-1000 EVO Intel and AMD platform installation demonstration

In this demonstration, the ASUS ROG Strix Z690-E GAMING and Asrock B650E TAICHI are utilized to illustrate the installation on the Intel LGA1700 and AMD AM5 platforms, respectively.

For the Intel platform, the included plastic backplane is used for installation. The first step is to adjust the backplane to align with the 1700 holes and affix it to the back of the motherboard. The backplane is secured with adhesive posts on the front, followed by using screws to fasten the metal bracket, and finally, the tower is locked into place.

Choose LGA1700 or 115X/1200 holes according to the platform.
Install the back panel.
Install the glue column.
Remember to install the CPU before installing the metal bracket.
Apply thermal paste and lock the radiator.
Remove and check whether the heat dissipation paste is uniform so as not to affect the heat dissipation performance if it is not installed properly.

For the AMD platform, you’ll use the backplane that comes with the motherboard. The first step is to remove the existing AMD latch while retaining the backplane. After that, install the adhesive post and the metal bracket, apply the thermal paste, and secure the radiator, mirroring the process used for the Intel platform.

The Jonsbo CR-1000 EVO is designed as an entry-level radiator, recommended for processors up to the Intel i5 or AMD R7 range. This evaluation puts the radiator to a rigorous test, focusing on real power utilization for assessing thermal performance, rather than just temperature performance.

In this instance, three usage scenarios were simulated: CINEBENCH R23 (Multi CORE) for high pressure, AIDA64 CPU for high load, and 3DMark Time SPY for low-pressure daily gaming. On the motherboard, XMP was activated, while other settings were left at default.

Here are the specific components of the test platforms:

Intel Test Platform:

  • Processor: Intel Core i7-13700
  • Motherboard: Asrock Z690 PG Velocita
  • Memory: Corsair Vengeance RGB DDR5 6000 32GB
  • Graphics Card: None
  • System Disk: AGI AI818 1TB NVMe PCIe 4.0 SSD
  • Cooler: Jonsbo CR-1000 EVO
  • Power Supply: CORSAIR HX1500i
  • Operating System: Windows 11 Pro 22H2

AMD Test Platform:

  • Processor: AMD RYZEN 7 7900
  • Motherboard: Asrock B650E TAICHI
  • Memory: Corsair Vengeance RGB DDR5 6000 32GB
  • Graphics Card: None
  • System Disk: PLEXTOR M9PeGn 512GB M.2 2280 PCIe SSD
  • Cooler: Jonsbo CR-1000 EVO
  • Power Supply: CORSAIR RM1000e
  • Operating system: Windows 11 Pro 22H2

The test results reveal that the Jonsbo CR-1000 EVO struggles to cool the Intel i7-13700 effectively, which is expected given that even previous water-cooling tests may have not achieved optimal temperatures. The cooling performance of the CR-1000 EVO on the Intel platform is roughly around 150W, making it suitable for i5-class CPUs.

However, the CR-1000 EVO performs much better on the AMD platform. The TDP of the AMD platform without the X suffix is just 65W, and the maximum power of the 7900 with PBO enabled is 90W. The CR-1000 EVO can efficiently cool this configuration, maintaining a very low temperature.


The Jonsbo CR-1000 EVO, featuring a top cover and fan with vibrant lighting, delivers a solid performance and a positive installation experience. It’s available for sale at the official Shopee Mall for 699 yuan and comes with a 3-year warranty. For a radiator with a single tower and a single fan, it’s quite the all-rounder, excelling in every aspect. It’s an appropriate choice for gamers looking to upgrade from a stock radiator, as it offers significantly better cooling performance and quietness. The only downside is the lack of lighting adjustability. If lighting control is important to you, an ARGB version from the same series is also available.
