[A-Series] Water Pump Pulley - Large
If you are running at high rpm regularly, you should use this larger pulley to slow the water pump down. Outside diameter is 119mm.
These pulleys have a thicker front face, so if you currently have the 4mm spacer behind the fan, you will no longer need to use this.
