XD5 squeaking noise

[BeachChicken420]

So I just finished building my new pc but my pump is making a off and on squeaking noise , any ideas on why and how to fix it

Try using fixed RPM/PWM% at various points to see if it’s specific to one part of the RPM band. 
 

I have seen loops emit a squeal/squeak when there is a pressure imbalance. Usually this occurs when a valve somewhere is not opened or the flow path has a fundamental design problem. Not really enough information to say if this in play, but if you loosen the reservoir cap and it stops, that may be an indication.

@c-attack my mobo says to plug the pump header into the aio header which is unadjustable and is a constant 100%

it's not an AIO pump 🙂

that header is beefier, to power AIO pumps directly (typically 3A instead of the 1A per fan header).

Your pump is powered striaight from the power supply, so it doesn't matter. you can use the CPU fan header if you like. That's usually the one to use, to get an alarm from the motherboard if the pump doesn't spin.

yep, well it's 1A only but it's still an AIO header. You don't need the full speed behaviour for a custom loop pump. You need an adjustable header, that's why most people use the CPU one or any of the chassis fan headers instead. The CPU one makes more sense because it generates an alarm if the pump  doesn't spin.

AIO Pump is just a converted chassis fan header with a default 100% speed.  It's marketing $^#^@ and would have more functionality if it were a standard CHA fan header.  As mentioned above, it is not supplying power but it will keep the XD5 pinned at 4800 rpm is you don't unlock it.  That in itself is going to make some noise.  Most MBs now have a release to restore fan control to it, but often it is really limited -- like CPU temp control only.  If you are using a Commander Pro, I would want it there.  If not, any standard CHA fan will do.  Those usually can take a temp probe signal if your MB has a 2 prong input for that.  CPU/OPT are usually CPU temp only.
