The water cooling quality of the old brand cool cooling is beyond doubt, and there is no problem with 13900k overclocking.The second generation fan and cold head collapse pump both achieve high performance and quiet, and the rgb color of the fan is also very correct, which is easy to install and use with their own hub.The only fly in the ointment is that there is no reversing fan in the seascape room and only reversing fan can be installed.
