Key Features of 40mm Aluminium Alloy Water Cooling Block
- Premium Aluminium Alloy Construction: Lightweight yet highly thermally conductive 6061 aluminium ensures rapid heat absorption from the mounted component.
- Precision CNC-Machined Micro-Channels: Internal serpentine or multi-pass flow channels dramatically increase water-to-metal surface area for maximum cooling efficiency.
- Compact 40mm x 40mm Footprint: Perfectly sized to cover small to medium heat sources including TEC Peltier modules, 40mm CPU/GPU dies, laser diodes, and LED arrays.
- Leak-Proof O-Ring Seal: Integrated rubber gasket between the top and bottom halves prevents coolant leaks under normal operating pressures.
- Universal 6mm Barbed Fittings: Inlet and outlet nozzles accept standard 6mm ID silicone or PVC tubing - compatible with most hobby-grade water pumps and cooling loops.
- M3 Corner Mounting Holes: Four screw holes allow secure, flush mounting onto heatsinks, processors, or custom brackets with thermal paste or pads.
- Smooth Machined Contact Surface: Flat, polished bottom face ensures excellent thermal interface when paired with thermal compound.
- Corrosion-Resistant Finish: Anodized exterior resists oxidation from prolonged water contact and ambient moisture.
- Low Flow Resistance: Optimized channel geometry maintains efficient cooling even at modest pump flow rates (1-2 L/min).
- Versatile & Reusable: Easy to disassemble, clean, and reuse across multiple projects and cooling setups.
- 100% authentic from trusted suppliers - CNC-machined to precise tolerances
- Ideal balance of cost, weight, and thermal performance for maker and hobbyist builds
- Drop-in compatible with standard 40mm TEC modules and common mini water pumps
Perfect For
- Peltier/TEC Cooling System: Mount directly onto a 40mm thermoelectric cooler module to dissipate the hot side efficiently - perfect for mini fridges, CPU coolers, or dew-point controllers.
- High-Power LED Cooling: Keep COB LEDs or UV LED arrays within safe junction temperatures during extended operation in grow lights, projectors, or curing systems.
- Laser Diode/Head Cooling: Maintain stable lasing temperatures on CNC laser engravers and cutters by liquid-cooling the laser module mount.
- 3D Printer Hotend Cooling: Use in custom all-metal hotend designs where air cooling is insufficient, especially in enclosed heated chambers.
- Overclocked SBC/CPU Cooling: Build a silent water-cooling loop for Raspberry Pi, Jetson Nano, or other single-board computers running intensive AI/ML workloads.
