Key specs explained
Socket Compatibility: AM4
This block fits AMD AM4 motherboards directly. You do not need separate mounting brackets for most AM4 CPUs. It also supports older AM2, AM3, and FM2+ sockets. This wide range means one purchase works for many AMD platforms. Check your motherboard manual to confirm the socket type before buying. This ensures a secure fit without gaps.
Material: Red copper
The base uses red copper for heat transfer. Copper conducts heat faster than aluminum. This helps move thermal energy from your CPU into the coolant quickly. You get better cooling performance with this material choice. It is the standard for high-efficiency water blocks. Look for copper bases when comparing custom loop parts for optimal thermal conductivity.
Height: 3 mm
The copper base is only 3 mm thick. This thin profile reduces thermal resistance. Heat travels through the metal faster. It allows the block to sit closer to the CPU die. This design suits cases with limited clearance. Verify your case compatibility before installation. A thinner base generally improves temperature readings in custom liquid cooling loops.
Micro water channel
The base contains micro water channels. These small passages increase surface area. Coolant flows through these channels to absorb more heat. This design improves heat exchange efficiency. You get lower temperatures with the same flow rate. Compare this to flat bases when shopping. Micro channels are a key feature for high-performance custom cooling blocks.
Materials and physical design
The listing specifies a red copper base for this water block. Copper conducts heat efficiently, which helps transfer thermal energy from the processor to the coolant. The base surface features micro water channels. These channels increase the surface area in contact with the flowing liquid. This design aims to improve heat absorption speed compared to flat surfaces. The copper base height is listed as three millimeters. This dimension affects how the block sits relative to the CPU heat spreader.
The top cover is made of transparent acrylic. This material allows you to see the coolant flow and any bubbles inside the block. It provides a visual element without adding significant weight. The mounting mechanism uses a stainless steel buckle holder. Stainless steel offers durability and resistance to corrosion over time. This hardware secures the block to the motherboard socket. The listing notes the width, height, and length are all 0.39 inches. These compact dimensions suggest a small footprint on the CPU socket area.
According to the listing, the large water area helps carry heat away quickly. The anti-oxidization technology on the copper base is intended to prevent degradation. This treatment may extend the lifespan of the block in a liquid environment. The combination of materials suggests a focus on direct thermal contact and visual clarity. You should ensure your case has enough clearance for the acrylic top and stainless steel hardware.
Setup and everyday use
Installing this block requires aligning the stainless steel buckle holder with your AM4 motherboard holes. The listing confirms compatibility with AM2, AM2+, AM3, AM3+, AM4, and FM2+ sockets. This means you can reuse the same mounting hardware if you upgrade to an older AMD platform. The base height is 3 mm, which is thin. This low profile helps ensure the block sits flat against the CPU integrated heat spreader. A flat seal is critical for heat transfer. You will need to connect the input and output ports to your loop tubing. The transparent acrylic top cover allows you to see the coolant flow. This visual element is purely aesthetic. It does not affect thermal performance. The red copper base is treated with anti-oxidization technology. This treatment helps prevent corrosion inside the base over time. You do not need to add special inhibitors for the copper itself, though your loop fluid choice still matters for other components. The large water area is designed to absorb heat quickly. This suggests the block can handle moderate thermal loads. The micro water channels increase the surface area in contact with the coolant. This design improves efficiency. Daily use involves monitoring your loop temperature. The thin copper base responds fast to changes in CPU load. You should check the mounting screws periodically. Vibration from fans or pumps can loosen mounts. The stainless steel holder is durable, but thermal cycling still stresses the seal. Ensure your tubing connections are tight. The acrylic top is brittle. Handle it with care during cleaning. This block is a straightforward add-on for any custom loop built on AMD hardware.
What You Need To Know
This block is a passive component for custom loops. You must supply your own pump, reservoir, tubing, and radiator. It does not include fans or coolant. Ensure your pump provides adequate flow for the micro channels in the base. The copper base requires proper coolant chemistry to prevent oxidation over time. While anti-oxidization technology helps, regular maintenance is still necessary. This solution suits builders who prefer direct-mount blocks for AM4 sockets. It offers a compact footprint compared to larger AIO units. You save space inside the case but handle more assembly work. Check that your case has room for the radiator you choose. This block fits well in small form factor builds where space is tight. It is a solid choice for enthusiasts who want to control every part of their cooling system. You need to source compatible fittings for your tubing size. This approach gives you flexibility in loop design. It is ideal for those who enjoy the hobby of custom loop building.
Check before you buy
- Verify your motherboard has AM4 mounting holes.
- Ensure your loop includes a pump and radiator.
- Check that your case fits the chosen radiator.
- Confirm tubing size matches your fitting requirements.
- Select coolant compatible with copper components.
