Watercool HEATKILLER® SWX-A4 LT

The HEATKILLER® SW-X series is a modular system for cooling of Mainboard voltage regulator modules. In combination with the also modular HEATKILLER® NSB 3.0 series the whole Mainboard can be cooled.

The stock cooling solutions on Mainboards often do not have enough cooling potential respectively work at their thermal limit. When removing the CPU fan by installing a water block the thermal stress on the components becomes even greater.
Especially on high-performance Mainboards the thermally sensitive components should hence be integrated in to the water cooling system. The gained cooling and performance potential allow your system to work reliably even under extreme loads.

The HEATKILLER® SW-X is designed as a modular unit. By exchanging the cooling plate it is possible to rebuild the water block to fit onto different components. Optionally available rebuilding kits allow use of the top parts of the water block even on completely different hardware.
The whole water block is CC-manufactured and is made completely from copper (LT-version with POM top piece). The large cooling channel reduces the flow resistance to a minimum.

To make choosing the right water block for your system easier, we recommend looking for your Mainboard in the following compatibility list:

For some Mainboard kits with North- and Southbridge as well as VRM water blocks are available.
