" rel="nofollow - What cooler do you have? You can connect the pump directly to your power supply so it runs at full speed and plug the fan to the motherboard to control the fan speed. ------------- https://valid.x86.fr/1tkblf" rel="nofollow">

Nice cooler BTW. According to Step#4 in the manual you can connect the fans and pump together or separately, and there is no loss in pump performance if you do. However, if you want/need the maximum cooling performance then plug the pump directly to a 12v supply. This way you can adjust the fan speed for noise and performance without it affecting pump speed. I didn't see any software included in the package,...so you will have to use the motherboard BIOS/UEFI to control the fan speed on the 4-pin motherboard connector. Of course, you can also connect the pump directly to the 3-pin motherboard fan/chassis connect and set it to full speed and it will receive full voltage/speed as well and you can monitor its speed. ------------- https://valid.x86.fr/1tkblf" rel="nofollow">
