Dual fan AIO CPU cooler, part from my old pc that goes with the motherboard on the second photo, I asked asus themself and they don’t know the exact model of the cooler as it was one of their pre built, had the part and used it for about 6 months and it’s worked perfectly with no issues, i’ll include all the bolts and screws it came with aswelll as spare thermal paste! This fit my Intel board, if you have an AMD system you may be able to buy a bracket to fit to your board.
