[SOLVED] Air in water loop?

Hello,
I know something similar has been asked in other threads. My water cooler is making clicking / whirring sounds kind of like a hard drive. I would say it’s due to air in the loop, but I’ve turned it on its side to see if it moved the air through, but that didn’t seem to help. The strange thing is that the noise only seems to really be noticeable during low CPU load. When I’m gaming with a 50% or so CPU load, the water cooler seems to be a bit louder than it should be, but I don’t notice this clicking sound. The sound is definitely coming from up by the reservoir. I use an ASUS z170 motherboard and swiftech H320X2 Prestige Triple 120mm fan AIO water cooler. The PC is about 3 years old, but I haven’t done any sort of water replacement or top off with it. The CPU temp seems to be normal.
Thank you!
 
Solution
you could be from pump of fans first try to press one pipe on pump to see if the sound goes out also check if there is any cable touching the fan blade on cooler .
