Hi there. I've had a custom loop assembled for a couple of years now, in this sequence:
Alphacool Eisbecher D5 250mm
Alphacool Eisblock XPX Aurora - Plexi Chrome Digital RGB
Alphacool NexXxoS ST30 Full Copper 240mm radiator V.2
Alphacool Eisblock Aurora Plexi GPX-A Radeon RX 5700 XT Thicc II / III
Alphacool NexXxoS ST30 Full Copper 240mm radiator V.2
I was trying to make a custom case, and all, a hobby which I have now stopped for other reasons. So at the time, it was "assembled" simply by having the components on top of the desk, no case at all, just all components on riser screws, with somewhere near a meter of tubing in between, so I could move things around. As you can see, going back and forth between cooler and radiator involved a lot of tubing.
Amazingly, it worked perfectly.
So after I decided to assemble all this in a decent case, while I finish doing my hobby "case", suddenly the problem started. The pump started whining really low ( I have the whole loop on low speed until the temperature rises ) but at a frequency not even noise cancelling headphones can hide, and it's just unnerving.
I researched and it's said the order of the coolers in the loop doesn't matter that much in terms of cooling and efficiency... It's still weird to me, but whatever, I just wanted to try something to get this whine off.
So I switched the GPU block with a radiator, so it became
Alphacool Eisbecher D5 250mm
Alphacool Eisblock XPX Aurora - Plexi Chrome Digital RGB
Alphacool Eisblock Aurora Plexi GPX-A Radeon RX 5700 XT Thicc II / III
Alphacool NexXxoS ST30 Full Copper 240mm radiator V.2
Alphacool NexXxoS ST30 Full Copper 240mm radiator V.2
All in all, this allowed me to cut most of the tubing. I made sure it had the least possible upwards flow ( since gravity is still a thing, I think ), and made it as short as possible. I tried several different configurations, and the whine persists. I tried isolating blocks, starting from a pump-only loop, and adding one by one, and the whine only started after adding the first radiator. Why? I have no idea. From what I could see from the flow of water coming back to the pump, the block that opposes the flow the most is the GPU block, before adding it, it would reappear at the reservoir with a nice pressure, after adding it to the loop, it became a lot slower.
I have no complaints about the performance though ( at least, not yet ), it's just the bloody whining that is driving me nuts, and it wasn't there before.
I took some pictures but can't attach them, since they're too large, apparently. I'll share them here. Sorry for the quality, it's not easy to access.
What am I doing wrong?
