I had an issue with cooling my cpu a while ago and decided to get a new water-cooler, then i got a couple of fans for it. I don't know the policy on products on here but I guess the important part about them is that they are less than 30 dBA.
When I was tinkering around I noticed that when one fan is plugger in, taking in air from the back of the chassi into the radiator. It was pretty much noiseless regardless of stress. IE at 40-100% speed it was pretty quiet.
Then I plug in the other one, on the other side of the radiator, like so: ->|-> where arrows are fans and the line is the radiator. I noticed that the sound level had increased a noticeable amount on low speed, and at full speed it sounds really bad, like a high frequency whining. The fans themselves are not defective. The issue only comes up when they are placed on both sides of the heatsinks as shown.
If anyone has any ideas as to why this is or how to solve this it would be greatly appreciated. Thank you for reading.
