Who it fits

Key specs explained

Radiator Size: 240mm

This dimension indicates the radiator fits two 120mm fans side by side. It is a compact form factor that suits many mid-tower cases. You can mount it in the front, top, or rear of your chassis. Choose this size if you have limited space but want strong cooling. Larger sizes like 360mm or 480mm offer more surface area for heat dissipation.

Thickness: 55mm

The radiator is 55mm thick, which is considered high profile. This extra depth provides more copper and fin surface area for heat exchange. You get better cooling performance compared to standard 30mm or 40mm radiators. Ensure your case has enough clearance for this thickness. It pairs well with high-static pressure fans to push air through the dense core effectively.

Core Material: Premium Copper

The core is made from premium copper, a metal with excellent thermal conductivity. This material transfers heat from the water to the fins efficiently. It is optimized for use with copper water blocks in your loop. Copper cores generally outperform aluminum in thermal performance. This construction ensures your CPU and GPU stay cool under heavy loads.

Fin Thickness: 25-micron

The cooling fins are 25 microns thin. This extreme thinness allows for a higher density of fins within the same space. More fins mean more surface area for air to cool. This design maximizes heat dissipation without increasing the overall radiator size. It requires fans with good static pressure to move air through these tight gaps.

Design and Build Quality

The Corsair Hydro X XR7 240mm V2 radiator uses a premium copper core. According to the listing, this material provides a high thermal transfer rate. The cooling fins are 25 microns thin. This thinness increases the surface area for heat dissipation. The radiator measures 55mm in thickness. This dimension allows for efficient cooling when paired with high-airflow fans. It also helps keep noise levels low during operation.

The unit weighs 2.05 pounds and measures 10.9 inches long. Its width is 4.72 inches and height is 2.17 inches. These dimensions fit standard 240mm mounting spots in most cases. You can place it in the front, top, or rear of your chassis. The black finish features a high-quality polyurethane coating. This coating provides a flawless look that matches your system components.

Corsair moved the inlet and outlet ports in this V2 model. According to the listing, this change makes it easier to attach fan cables. This is especially useful if you use iCUE Link fans. The dual 120mm fan mounts are positioned on either side. This layout supports ambitious custom liquid cooling builds. The design prioritizes accessibility and clean cable management. You get a sturdy core with a practical layout for tight spaces.

Setup And Everyday Use

Setting up this radiator involves fitting it into your case and connecting the cooling loop. The 240mm size means you need space for two 120mm fans. You can mount it in the front, top, or rear of your chassis. The listing highlights an easy access design. The inlet and outlet ports are positioned to help you attach fan cables. This includes compatibility with iCUE Link fans. This placement reduces cable clutter near the pump and reservoir. You will need to ensure your case supports the 55mm thickness. The unit weighs 2.05 pounds. This weight is manageable for most standard case mounts. The black finish matches many system builds. You do not need to worry about visual clashes with other components. The premium copper core requires proper coolant selection. Ensure your fluid is compatible with copper to prevent corrosion. The 25-micron thin fins increase surface area. This design helps dissipate heat efficiently. You should use high-airflow fans to maximize performance. Low-noise fans also work well due to the large surface area. The polyurethane coating protects the exterior. It keeps the radiator looking clean during daily use. You will not need to adjust settings frequently. The hardware is passive in terms of electronics. It relies on your pump and fans for operation. Check your case dimensions before purchase. The length is 10.9 inches. The width is 4.72 inches. These measurements fit standard ATX cases. Ensure you have enough clearance for the tubing connections. The port location simplifies this step. You can route tubes more easily. This makes the initial build process smoother. Daily use involves monitoring loop temperatures. The high surface area helps keep them low. You get stable performance under load. The copper construction ensures long-term durability. This setup is ideal for enthusiasts who want a clean look and efficient cooling. No software is required for the radiator itself. It works with your existing loop components. Just fill, bleed, and run. The design supports ambitious custom loops. You can pair it with various water blocks. The compatibility list suggests it works well with Corsair performance blocks. This ensures optimal thermal transfer. Your system will run quietly and coolly.

Before You Buy This Radiator

Before you buy this Corsair Hydro X XR7 240mm V2 radiator, verify your case dimensions. The listing notes a 55mm thickness. You need ample clearance for fans and tubing. Check that your chassis supports dual 120mm mounts on the chosen side. This unit is designed for custom loops, not pre-baked AIOs. You must purchase separate fittings, tubing, and a pump reservoir combo. Ensure your water blocks are compatible with the premium copper core. The inlet and outlet ports are positioned for easier cable access. This design helps when routing fan cables, including iCUE LINK fans. Regular maintenance includes checking for leaks and cleaning dust from the 25-micron fins. Compare this 240mm option against the 360mm and 480mm variations if you need more cooling surface. This radiator suits users prioritizing high thermal transfer rates and a sleek black finish. It fits well in mid-tower builds where space is managed carefully.

Check before you buy

• Verify case clearance for the 55mm thickness and dual 120mm fans
• Confirm compatibility with your copper water blocks and loop components
• Check port orientation for easy fan cable and tubing routing
• Compare against 360mm and 480mm options for higher heat loads
