New build makes noise...

Hi,

Took me a grooling 5 hours to build my PC as I love good cable management

It was my first time also using a AIO for the cpu.

First thing I noticed on power up was a scratchy type noise, almost identical to how a HDD sounds when doing read/writes, but constantly. Took the panel off and my ear tells me its coming from the CPU/waterblock pump. Is this standard noice for the Corsair H100i RGB Platinum.

I have the Corsair 220T Airflow case and my initail veiw is the cpu is running warmer than id expect ranging from ~40-60 degrees C.
At the moment im just installing all the apps i want, and have the side panal off so ive not left it to idle in a closed case yet... but that brings me to my next challange:

My MoBo is Strix B450-E, I set all the chassi fans (bar the CPU) to a "silent profile" in the Bios. I noticed the thresh hold for increased speed is 50c (bang in the middle of my temp ranges) so they are constantly going up and down :rolleyes:

but tbh its really not that quiet when below 50c.

Hoping someone can help or give tips on either issue.
Thanks

Sounds like there's air in pump.
Is radiator above or below pump?
If below air could be rising to block and pump.
Which can also decrease cooling effiency.
Not that its continuous cooling performance is that great in the first place...

Front mounted pipes going to the top... so you could say above, now its been running for a few hours it seems to have gone a little quieter or i have got used to it but I can still hear it if i put my head closer.
I will monitor it for a few days before doing anything drastic.

Thanks

whilst the PC is on and running, give the case a gentle shake and lean it backwards to try a force any air in the block / pump back to the radiator

Sounds like the AIO pump. Usually at standard they run quite fast in perf mode which is usually around 3000rpm+ quite noisy. Had the same AIO before with the same issue so it should sort it.

Download and install Corsair link and drop the pump speed to quiet mode. Won’t make much if any difference to temps but will get rid of the AIO noise.

Plus you can setup a fan profile on Corsair link as well. Bios is mostly useless to be honest.

Pump running some time could force some of the air bubbles move forward.
But if block/pump is the highest point of the loop, probability is for air trying to rise back there when PC is powered down.

It is practically unnoticable now, if at all even making a sound... so it must have just been from starting new and has shifted any air if that was the problem

thanks for the help!

Im begining to learn this, Ive been in the Bios a few times trying to quieten down the fans.
I ran a Q-Fan analysis and the first time it dropped all the fans minimums to near 20%, so I was able to creat a nice quiet profile that picked up and increased with temp when the CPU hit the 65mark and so on...

I then did some messing about to get my Ram to its spec'd 3200mhz where i needed to reset the Bios after if bluescreened (got it all stable now) but when i ran the Q-fan again it set the minimum on the CPU-FAN to 90%!! and won't go any lower? To be honest im not entirely sure what it is doing when running this test, but now all my chassi fans are set to a 60% minimum... this is all for manual settings... but then the preset profiles (silent, turbo etc) are no better hence wanting to use a manual setting. it wont let me set it any lower than the minimum after the Q-Fan Analysis :confused:

Unfortunetly my MoBo doesnt have enough USB headers, so im waiting for an Internal hub to arrive before I can attach the AIO to a usb header, the usb is currently being used by the lighting node core (3 chassi fans).
Just installed Corsair link now doesnt appear to be compatible with my Node Core so will need to use the Bios for these.

Wait... Ive just thought, I did have the AIO on the usb header previosuly which may have been when it initaially allowed a manual setting of 20% (although no logic tells me why it would do this)... Im wondering if a RGB profile can be saved to the Lighting Node Core, then I can use the usb header for the AIO.

A further question and thanks for read all this:
My Mobo has CPU_FAN (AIO is connected as instructed in the manual)
CPU_OPT which ive attached rear my exhaust fan too (reading it mimics the cpu fan - so is they increase due to temp it seems wise for this one too aswell, no?

)

but I also have AIO_PUMP header and wondering should I be using this instead of the CPU_FAN specified in the H100i manual.
I am assuming the fan header is to give the Mobo a reading on what the AIO pump speed is. But ultimately it uses the sata power connection for its power and power to the two fans... further more the AIO has a profile built in so doesnt care about the power suggested/suppled by the mobo?

I'll plug the AIO usb in now and have a play around...
Thanks

If block/pump is loop's highest point that air can well make its way back there.
While pump churning constantly might have mixed that air into small bubbles evenly distributed, shutting PC down starts process of those bubbles gathering into bigger ones and trying to rise up.

Have plenty of experience with central heating and air bubbles in pumps can make quite various noises, including what can be described as "scratchy" higher frequency sound.
