What customers say
This Coolgate 140mm radiator earns high praise, especially from SFF builders prioritizing thermal performance in tight spaces. Customers consistently highlight the exceptional build quality, noting robust construction and a durable finish that supports its premium cost. The standout feature is its superior cooling capacity; users report impressive temperature drops, confirming its effectiveness for high-end dissipation. While the dense core design causes slightly higher flow restriction, most agree this is a worthwhile trade-off for the cooling gains. The consensus is clear: this unit delivers benchmark performance and reliability for serious water-cooling setups where space is limited but compromise is not an option.
Know before you buy
The radiator measures 191mm in length, 142mm in width, and has a thickness of 60mm. Please ensure your PC case has sufficient clearance for this 60mm depth before installation.
Yes, it features an optimized fin-per-inch (FPI) count specifically designed to maintain high thermal efficiency even when paired with low-speed, quiet fans.
The radiator uses standard G1/4 threaded ports, which are the industry standard for custom water cooling loops. This ensures broad compatibility with most aftermarket compression and barb fittings.
The included silencers help decouple the fan from the radiator frame, reducing vibration-induced noise. They also create a tighter seal, which improves static pressure and overall cooling performance.
The radiator is constructed with 90% copper inner tubes and copper fins, which are excellent for thermal conductivity. To prevent galvanic corrosion, we recommend using it in a loop with other copper, brass, or nickel-plated components and avoiding aluminum parts.
The triple parallel row configuration is engineered to minimize water flow resistance. This allows your pump to circulate coolant more efficiently, which can improve the overall flow rate of your cooling loop.
