Arctic Freezer 4U-M RAM Air Guide / Baffle

This is an air baffle for the 4-UM heatsink/cooler from Arctic. It replaces the default front shroud and will help guide air that would otherwise go around the CPU heatsink down towards the memory modules on either side.

The left side baffle is slightly thinner than the right one so that it will not touch any PCIe cards used in the top slot of the motherboard however this may vary depending on the motherboard you're using. In my case I'm using a Supermicro H12SSL-HT. This model should definitely fit all H12SSL varients of motherboard when combined with the Arctic 4-UM heatsink.

The model features holes to fit a 120mm fan replacing the original front shroud that is usually found on this heatsink, make special attention to the components on your motherboard which are high up near where the fan will occupy when using this mount as it may foul them. This is why the model doesn't feature a full 120mm mount and only the top half as the lower portion would sit very low. The rear shroud on the heatsink can still be used like normal.

There are minimal supports needed for this model and it features built-in clips to connect onto the heatsink using the same mounting channels that the default shroud uses.
