Description

The high-performance fan series (PN: 03GX153, 03GX154, 02JG447, 03KH521, 02JK422, 03KH522, 02JK421) is specifically designed for Lenovo SR650V2 and SR665 enterprise servers, serving as a core cooling component to ensure stable operation of server hardware under high-load conditions. As original used fans from Lenovo servers, they have undergone strict functional testing and quality inspection, with intact cooling performance, no obvious physical damage, and consistent compatibility with the original server configuration.
These high-performance fans adopt dual-rotor design (60 x 60 x 56 mm) with a rated speed of up to 19000 RPM, delivering strong air flow and efficient heat dissipation to cope with the heat generated by high-performance CPUs, memory modules, and other core components in SR650V2/SR665 servers. They support hot-swap functionality, allowing for on-site maintenance and replacement without shutting down the server, which effectively reduces enterprise downtime and ensures continuous operation of business systems.
Each fan model (03GX153, 03GX154, 02JG447, 03KH521, 02JK422, 03KH522, 02JK421) is fully compatible with Lenovo SR650V2 and SR665 servers, perfectly matching the server's cooling system and control logic. The fans feature intelligent speed adjustment, which can automatically adjust the rotation speed according to the server's internal temperature, balancing cooling efficiency and noise control, and avoiding unnecessary energy consumption.
As cost-effective original parts, these high-performance fans provide an economical alternative for enterprise server maintenance and replacement. They retain the original factory specifications and performance, ensuring consistent cooling effect with new fans, while significantly reducing maintenance costs. For enterprises using Lenovo SR650V2/SR665 servers, these fans are the ideal choice for cooling system upgrades, failures replacement, and daily maintenance.

Frequently Asked Questions

Q1: Are these fans new or used? A: They are original used fans from Lenovo SR650V2/SR665 servers, strictly tested and inspected to ensure intact cooling performance, no functional defects, and stable operation.
Q2: Are all 7 models (03GX153, 03GX154, etc.) compatible with both SR650V2 and SR665 servers? A: Yes, all 7 specified part numbers are fully compatible with both Lenovo SR650V2 and SR665 servers, and can be directly replaced without additional configuration.
Q3: Do these fans support hot-swap? A: Yes, they support hot-swap functionality, which allows for on-site replacement without shutting down the server, effectively reducing enterprise downtime.
Q4: Can single-rotor and dual-rotor fans be mixed use in the server? A: No, single-rotor and dual-rotor fans cannot be mixed use. It is recommended to use the same type of fan to ensure the cooling system operates stably and efficiently.
Q5: Why does the fan still run when the server is shut down but powered on? A: This is a normal system design. When the server is shut down but still connected to AC power, some fans may continue to run at low speed to provide appropriate heat dissipation for internal components.
