What customers say
Customers overwhelmingly praise the EK Quantum Surface P240 for its exceptional thermal performance and premium build quality. Its substantial thickness and high fin density effectively manage significant heat loads, making it a top choice for overclocked systems. Reviewers consistently highlight the robust construction and clean matte black finish, reinforcing its high-end positioning. A key consideration noted is that achieving peak cooling requires pairing the radiator with high static pressure fans running at medium to high speeds, which may impact acoustics. While the price is premium, the consensus is that the superior cooling capacity and lasting quality justify the investment for builders prioritizing maximum performance in a 240mm format.
Know before you buy
With a thickness of 30mm, this radiator is designed specifically for space-constrained builds. However, you should always check your case's clearance specifications to ensure there is enough room for the radiator plus your chosen fans.
Yes, the P240 is engineered to be highly efficient even at lower fan speeds. This makes it an excellent choice if you are prioritizing a silent PC build without sacrificing thermal performance.
The radiator features copper tubes and fins for optimal heat transfer, while the end plates are constructed from durable steel. This combination ensures both high thermal conductivity and structural integrity.
Yes, the EK-Quantum Surface P240 uses standard G1/4" threaded ports. It is fully compatible with the vast majority of custom watercooling fittings and tubing types currently on the market.
While the P240 can handle a CPU and GPU loop, its cooling capacity depends on the total heat output of your components. For high-wattage hardware, ensure your loop has sufficient surface area or consider adding a second radiator if temperatures exceed your preferences.
