EVGA CLC 120 not working right when connected to the CPU Fan header

[dakota.lapointe]

I just upgraded to a Ryzen 5 from an Intel i7 870, so I had to buy a new motherboard as well. On my old set up the EVGA CLC 120 aio cooler was plugged into the CPU fan header and ran at about 2800 RPM on full speed averaging load temps at about 50-55 degrees C.

The new Ryzen is much cooler never topping 45 degrees while under the same load. But I did notice that my pump speed in the EVGA flow control software would never go faster than 1980 rpm even with the pump speed set at 100%. Normally I understand that the aio fan would plug into the cpu header and the pump would be plugged into a sys fan to keep the pump running 100% all the time but the CLC 120 pump and fan are both powered through a single 3 pin connector.

I currently have the fan/pump plugged into SYS1 header and pump never gets passed 1980 rpm as it did before.

When I plug it into my CPU fan header the led lights on the pump are dim and both the fan and pump do not move.

Why aren't I reaching the full RPM speeds that were previously capable and should I be worried that my pump is running much slower even though I am getting better temps?

Thanks for any help.

My system is
Ryzen 5 2600
2x4 GB 2400 mhz Hyper x Ram
500gb curcial mx 500 m.2 ssd
Evga CLC 120 AIO cooler
Asus Pheonix gtx 1050ti

I have the CLC 240 and had a similar problem until I manually set the fan header which the cooler is plugged into to 100% in the bios - I could then change speed with the flow control software.

That said, I run my pump at 2000 rpm as it's quieter and I don't need the extra cooling power.

Thanks that solved my problem, didn't realize that MSI had weird fan profiles set from stock.
