I have a Swiftech mcp35x2 pump and I plug it to the motherboard fan header to control the speed; however, it still runs at max speed instead of the curve I want. What can I do? That pump is noisy at max speed.
Im using apex 12. I plugged 1 pump to the fan header 3; the other to water pump header and the one on the water pump keep running full speed. The one on the channel 3 goes up and down a little bit but it stays almost at max speed, so I use split cable and connect both pump to fan header 3. Now they are running full speed whatever curve I set it up in the bios. I dont know because I put the pump vertical in stead of horizontal so that makes it runs at max speed. My case is lian li xl and I put the pump on the back.
