Help H100i Pro RGB (2018) Making odd noise

[Moonayyy]

Hello all, I am posting thread as I am looking for some help.

 

I have a H100i Pro RGB (2018) for my computer, normally when I first boot there's no strange noises, but during the colder months, Like right now it makes a odd noise that I can't really describe.

 

I am just wondering if there is something wrong or is it just due to the weather?

 

I can record a video tomorrow when I first boot up my computer if that is any help.

 

Thank you in advance to anyone that is able to help me

There really isn’t anything that should change with the pump’s operation between an ambient temperature of 15C vs 25C. So unless you are closing in on the freezing point, I am not sure what it could be. On the positive side, any kind of mechanical problem is not going to go away after the power on and would be omnipresent and increase/decrease in frequency with pump speed. That doesn’t sound like this situation at all. Are you sure it’s the AIO? Most PSUs need to do a fan power test at boot, even those with eco/zero fan modes. It would be easy to hear that in a cold, quiet Winter room and not necessarily in the warmer months with room fans, air conditioning, and whatever else raising the noise floor.

Hi, I usually have to do a cpu stress test to get the noise to stop. I don't know what else it would be besides the aio pump, my fans even spinning at the max doesn't make a sound that is similar. I will record it tomorrow when i turn the computer on

The pump speed does not change with CPU load or CPU temperature, so running a stress test should not change it. While in the idle state, you can toggle between Quiet/Balanced/Extreme on the pump to see if that has any effect. The load parameter is odd. It makes me wonder if there is something going on with the VRM on the motherboard.

[Moonayyy]

Changing between the modes didn't do anything.

I was not expecting the noise to change with the pump speed. If it did, it would indicate there is a mechanical or electrical issue with the pump. However, that noise in the background is not a VRM module, so that looks like a dead end.

 

Are you telling us it is 7C in the room?

[Moonayyy]

I'm not sure of the temperature of my room, I just put whatever snapchat gave me, the room is probably between 4 - 7 degrees celsius.

 

The sound went away after awhile, I'm not sure if thats because I had my heater on.

 

Theres no issues besides that noise (no overheating idle or playing games) and it only starts once I've gotten to the desktop.

 

I don't know what it would be besides temperature because it never happens in warmer weather or once the room gets warmer.

I don't know. We really don't have any user data for use at temperatures that low and it is certainly possible the mechanical pump sounds a bit odd in the single digit temp zone. If there is a minimum operating temperature for the unit aside from being above the freezing point, it has not come up. You could contact Corsair Support to see if they have a minimum operating temperature range for that model.

You really don't want to be running it at that low of a temperature. So it warming up might actually be why it goes away. In this case, there isn't really much that can be done other than running the heat in the room.

I know my H150i Elite Capellix makes a sound when powering down and sometimes on startup. I was able to capture the sound here. Sorry, you can hear someone mowing in the background. [ame=
