Know before you buy
The HEATKILLER IV PRO HWLUXX Edition is compatible with Intel sockets LGA 1150, 1151, 1155, 1156, 1200, 1700, and 1366.
No, this specific edition does not feature integrated RGB lighting. It utilizes a clear acrylic top, which allows you to see the coolant flow, but you would need to add external lighting strips if you want to illuminate the block.
The Easy-Mount System simplifies the installation process by allowing for tool-less adjustments once the initial mounting hardware is set up. This makes it significantly easier to remove or reseat the block during maintenance without needing to disassemble your entire loop.
Yes, the block is designed with a 25mm thread distance, which provides enough clearance to accommodate most extra-large fittings without interference.
The block features a nickel-plated copper coldplate for efficient heat transfer, a PLEXIGLAS GS acrylic top, and high-quality stainless steel brackets. The mounting system is constructed from nickel-plated brass for durability.
This HWLUXX edition is engineered for high-performance custom loops, offering up to 3°C better cooling performance than standard models. It also features an optimized internal structure that improves flow rates and reduces the likelihood of clogging over time.
