Know before you buy
The HEATKILLER IV PRO is specifically designed for Intel LGA 2011, 2011-3, and 2066 sockets.
The PLEXIGLAS GS top is durable, but you should avoid using aggressive cleaning agents or alcohol-based coolants, which can cause stress cracking. Stick to high-quality, manufacturer-recommended water cooling fluids to maintain the clarity and integrity of the acrylic.
Yes, the block is designed with a generous thread distance of 25mm, which provides enough clearance to support most extra-large compression fittings without interference.
The tool-less Easy-Mount System uses a pre-tensioned mechanism that allows you to secure the block firmly to the CPU socket without needing a screwdriver. This ensures consistent mounting pressure and significantly reduces the risk of overtightening or damaging the hardware.
The redesigned engine utilizes thinner fins to increase the surface area for heat transfer, resulting in up to 3°C better cooling performance compared to previous iterations. Additionally, the internal geometry is optimized to improve flow rates and minimize the risk of clogging over time.
