For north bridge cooler HR-05 motherboard compatibility, what we did basically was to check visually for any component interference that the NB cooler might have with its surroundings on the motherboard. For reference on the dimension and measurement of our bracket arms, please see below drawing. If your motherboard requires a bracket not indicated in below drawing and would like to request for a customized bracket, please write to: support@thermalright.com
