Hexagonal holes problem and CPU fan recommendation
Posted: Mon Jul 29, 2019 2:38 pm
Hello, I need advice about my case situation and fan recommendation.
- I have Define R5 and I put his stock fans to case fan controller. One stock fan is aimed at HDD cage (intake) and other is bottom intake. Problem is that when are fan on 7V I can hear sometimes humming noise like fan speed is going up and down. I read from this that this is known problem with R5 cases. From other forum:
"The humming is normally caused by the fans being too close to a hexagonal holes. I had the same problem on my Fractal XL R2."
"R5 is at fault, because of the shape of the holes. I tried with/without, different fans, and all different setups to isolate the issue. It is 100% the R5 top vents."
So can I solve this only but putting some smaller fan on bottom intake (120mm)? In reserve I have Noctua 120mm 700 redux but it can only work as far as I know on 12V so it will be needed to be connected to motherboard. Any other solution? I am pretty sure that bottm fan is the problem but I need to test it more.
- Other thing is that I want to replace my CPU fan which is Noctua industrial 3000, it has some buzzing noises (I read that is normal for those industrial fans?) and sometimes when I turn my PC during cold times I got a mesage that my CPU fan is no working. Than I restart computer and it starts normally, so maybe it start up with a delay and mbo after I turn PC on it recognises him as 0RPM at it gives that message? I have same situation with my previous board so fan must be the problem in this case. Any fan recommendation that doesn`t have problems (humming noise, PWM problems)?
My favorites (I want a silent fan with a good pressure):
- Coolermaster silencio 4pin 120mm
- Arctic Bionix P120 4pin
- Bequiet Silent wings 3 120mm 3 pin (I read that PWM versions has some problems)
Cooler is Coolermaster TPC 600, CPU is Ryzen R5 1600 but in future it will be replaced for some 12c Ryzen.
