Know before you buy
No. To prevent galvanic corrosion, you must only use this radiator in a loop with other copper or brass components. Mixing metals can lead to permanent damage to your cooling system.
The 30mm slim profile is designed for high compatibility, making it easier to fit in cases where space is limited compared to thicker radiators. However, you should always verify your case's clearance for a 280mm radiator and the combined thickness of the radiator plus your chosen fans.
This radiator uses standard G1/4" BSPP port threads. This is the industry standard for custom water cooling, so most aftermarket fittings will be compatible.
We recommend using CORSAIR XL coolant or an equivalent high-quality coolant specifically formulated for copper and brass custom loops. Avoid using tap water or non-specialized additives to ensure the longevity of your components.
Yes, the radiator uses M4xP0.7 screw threads. It includes the necessary hardware to mount your 140mm fans securely to the radiator frame.
The radiator is rated for a maximum operating coolant temperature of 60°C. For optimal performance and component longevity, most custom loops are designed to run well below this threshold.
