Fan Settings / Control Tips

Ive just build a new system and I'm wondering if I need to be adjusting any settings for the fans in the BIOS. My setup is 2x140mm intake, 1x140mm exhaust as well as the H100iGTX AIO mounted on top woth 2xSP120mm pwm fans.

Everything seems to be working properly in benchmarking and games although the ramp up speeds seem to be fairly random. The fans go from high to low to high again randomly (nothing bad). I was wondering if I need to configure them in a particular way so they ramp up when needed keeping the components at a low temp. I've also noticed the SP fans on the AIO seem ro stay at the same speed and in corsair link only show up as one fan.

I've done loads of research on everything when I built the system, besides fan settings. Any information, as detailed as you can give me, with whatever time you have spare would be fantastic. Thanks a lot.

If fans are ramping up when your system isn't under load, try setting fan curves in the bios that don't go as high when temps are lower. 

If Corsair link shows the fans as one, it may be that the fans are running off of a splitter or only one of them are plugged into the waterblock's header.

I've set the SP120mm fans (on the AIO) to PWM mode in the bios as they're pwm fans. Now I'm getting this weird buzzing sound from them. Is this normal or does it have to do with something that is insecure?

Are you sure you set the fans to pwm and not the pump?

This is what I've got at the moment. I assume the CPU fan means the fans and not the pump itself hopefully. I've just got it set to standard in the PWM mode. I'm guessing the buzzing is just the Pulsing (Pulse Width Modulation). 

 

The other 3 fans that are intake and exhaust are set to DC. They are the AF140mm and I'm not sure if they would benefit from or even support PWM.

 

I'm not sure about the benefits of PWM. All I can tell is that is making a buzzing noise now, haha.  

 

As far as the fans adjusting to the load, is this all done automatically?

The CPU_Fan header is just for whatever is plugged into that header--it doesn't necessarily mean that it is the fan used to cool your rad. 

The graph you see is the fan curve I was referring to. You can adjust how fast the fan goes depending on the cpu temp.
