Customer Reviews
Awesome combo if you’ve got the room.
Running this in a tr100 case and it fits great.
Only reason for 4 stars is the provided port diagram in online pictures. You technically only have 2 return ports that flow through the rad and 2 just return to the reservoir and completely bypass the rad if used.
That said once I noticed was an easy fix and it makes filling a loop in an itx build way better than cpu pump block combos I’ve used in the past
