FAQ

    Q Can Kingka waterblocks integrate with existing liquid cooling systems?

    A
    Yes. All waterblocks are compatible with standard G1/4 threaded fittings and can be integrated into custom liquid cooling loops for servers, AI clusters, and HPC systems.
     
  • How does Kingka ensure the durability and reliability of its waterblocks?

    We use premium materials, precision machining, and strict quality control to ensure long-term reliability. Nickel plating enhances corrosion resistance, while precision microchannels maximize thermal performance even under continuous heavy workloads.
     
  • Are these waterblocks suitable for high-density data centers and HPC clusters?

    Absolutely. Our waterblocks are specifically designed for high-density servers, AI/ML clusters, and HPC environments. They provide efficient heat transfer, reduce energy consumption, and allow higher system reliability.
     
  • What are the key performance specifications to consider?

    Important parameters include TDP support, microchannel design, recommended flow rate, operating pressure, operating temperature range, and mounting compatibility. All Kingka waterblocks are engineered to meet demanding server workloads.
     
  • Can these waterblocks be customized for specific servers?

    Yes. Kingka provides full customization, including dimensions, microchannel design, inlet/outlet positions, and visual options. We ensure compatibility with various CPU/GPU sockets and high-density server layouts.
     
  • What materials are used for Kingka waterblocks?

    Our waterblocks use high-quality materials such as bare copper, nickel-plated copper, aluminum alloy, and acrylic tops. We also offer POM or PPS for connectors and seals. Each material is selected for optimal thermal performance, durability, and compatibility with server environments.
  • What is a server CPU/GPU waterblock?

    A waterblock is a high-performance cooling component that directly contacts the CPU or GPU to transfer heat to the liquid cooling loop. It is designed for data centers, HPC clusters, and AI servers, ensuring stable operation under heavy load.
     
  • What is the lead time?

    Normally, the customized samples lead time is 15 days, the lead time for mass production is 25-30 days. It depends on the order quantity and the season you place the order.
  • What is your usual terms of payments?

    Usually it will be T/T in advance , we also can accept net 30 days for the long-term cooperation customer. Please check with our sales with details.
  • Can I customize surface treatment?

    Yes. We can supply anodized in various colors, hard anodizing, sandblasting, nickel plating, polishing, grinding, powder coating, electrophoresis and so on. It can be customized according to your requirements.
  • What documents will be offer along with the goods?

    Documents will be offered based on your requirement, like FAI report, PPAP, RoHS &material certification, control plan, COC and so on.
  • I do not have drawing, what can I do?

    We have a team of professional engineers can provide the customized design service for customer,please kindly tell me your detail requirements ,the draft drawing and samples pictures can be provided will much helpful.
  • Can you provide the sample for testing ?

    Yes ,we can provide the the sample for testing .
  • Are you trading company or manufacturer ?

    We are manufacturer for the CNC machining , turning , extrusion , skived fin process , soldering , brazing , FSW process , assembly and various hardware metal parts .
  • What materials are utilized for custom heat sink manufacturing?

    Standard production specifies high-purity aluminum alloys (AL6061, AL1070) for lightweight, cost-effective thermal management. For applications demanding maximum thermal conductivity, C1100 copper and advanced copper-aluminum composite materials are deployed.
  • Which manufacturing processes are available for high-density cooling?

    Advanced thermal requirements are met through precision manufacturing, including heat sink extrusion for standard profiles, cold forging for high-density pin fins, and skived fin heat sink technology for maximum fin density without interfacial thermal resistance.
  • How are extreme power and large-scale thermal loads managed?

    High-wattage applications utilize advanced liquid cold plates and precision water blocks. For air-cooled solutions, manufacturing distinguishes strictly between bonded fin heat sinks (assembled via thermal epoxy) and composited heat sinks (utilizing advanced soldering or vacuum brazing) to meet exact structural and thermal resistance specifications.
  • What is the standard lead time for thermal prototypes and mass production?

    Rapid prototyping for machined or extruded thermal profiles typically requires 7 to 10 business days. Full-scale mass production lead times generally range from 20 to 30 days following the approval of the first-article inspection.
  • Is there a minimum order quantity (MOQ) requirement?

    Flexible manufacturing operations support varying project scales. Production lines accommodate single-unit engineering verification builds, low-volume pilot runs, and continuous mass production exceeding 100,000 units without strict minimum volume constraints.
  • What secondary surface finishing options are provided?

    Comprehensive surface treatments enhance corrosion resistance and thermal emissivity. Standard industrial finishes include Type II and Hard Coat Type III anodizing, stainless steel passivation, electroless nickel plating, and chromate conversion coating (Alodine).
