Question about setting AIO pump correctly

[Sharkley22]

Hello everyone,
first of all I would like to apologize for any writing mistakes, because English is my second language. But back to the topic...
Yesterday I have mounted AIO for the first time to my PC (bequet! silent loop 2 280mm). Generally, everything works fine, CPU temperatures do not exceed 65 degrees, but I am concerned about my AIO pump speeds. Right know the motherboard set it up to 1800 RPM and that value is changing up to 2800 rpm depending on the CPU temperature. Im afraid that at idle 1800 RPM is to low. I have done some reserch and according to the producer website the voltage at which the pump should operate ranges from 9-12 volts. I have tried to set it up like that, but it looks like that, my motherboard (gigabyte b550 gaming x v2) does not allow setting fan or pump via voltage, I can only manipulate rpm values. Producent website states that pump RPM is 2800, so im assuming that this value is maximum voltage with which the pump can work, that is 12 volts. So in order to set it up to 9 volts (9-10V in order to keep the pump silent) I should set it up to 2100 RPM or it doesn't work in that way? I am kindly asking for help, because I do not want to break the newly purchased AIO.

just set it to static 100%.

Well... I tried that but at 100% pump is "buzzing" quite loudly, and the whole point of upgrading to AIO was to finally keep my proccesor cool and silent (meaby it was a mistake, at least it's cool right know). I have red-necked thought that If 100% is 2800 RPM and thats 12V, so 9V should be 2100 RPM am I right or that logic is completely wrong?

You should be able to have fans run off the board, AIO to be on the AIO header.

I have plugged aio pump according to Gigabyte manual that is to the CPU OPT, by the looks of it this motherboard doesn't have a described and dedicated AIO header like for example some ASUS one's.

then set it gradually lower until it's not annoyingly loud. but have a static RPM it's a lot better for bearings/motors in general.

So i should set it up with the "RPM Fixed Mode" in my BIOS? But at which value, i don't want to over do this and go below 9V and break the pump .

What Gigabyte board do you have? On mine there's two dedicated AIO/PUMP headers

how are you supposed to break a product that is literally running in spec? 9V is probably the minimum to make it even start working.

 

[Sharkley22]

So guys any do have any idea on how much rpm should I set it in order to run the AIO pump on 9V?

I think you are confusing things, it sounds like the pump is DC controlled, so the header has 3 pins, which means it's controlled by varying the voltage. The way that works is at some point the voltage becomes high enough that the pump starts spinning (this varies from pump to pump. or fan to fan) and then at 12V it reaches it's maximum speed, you don't have to worry about breaking anything, that's just how that works. There is no predetermined RPM at which it spins if the voltage is 9V, this varies from product to product and it's of no relevance to you.

I suggest just leaving it as is, it's actually better that it's not spinning at it maximum speed all the time for longevity.

1. All moving parts generate noise.
2. As long as temp stay below 90 C it will be hard to get a warranty replacement and you are only as good as your ambient temp.
3. Try setting BIOS header speed to 100%.
4. Do not overtighten the AIO mounts or use excessive paste.
