DidAllCould Posted December 3, 2017 Share Posted December 3, 2017 I have recently installed this and replaced a few fans in my computer. I was wondering what could cause this and how I might fix this like reving/pulsing of the fans. Almost sounds like someone breathing. Link to comment Share on other sites More sharing options...
DidAllCould Posted December 4, 2017 Author Share Posted December 4, 2017 I have tried uninstalling both Suite 3 and corsair. I have tried disabling Q-Fan in bios and currently running it that way. But I can still hear a faint pulsing of the fans (low to high) up and down levels of noise. Meaning there is a change in fan speed for a split second or something? I am not sure.

DevBiker Posted December 4, 2017 Share Posted December 4, 2017 First, make sure Link is installed. Once it's installed, you need to make sure that the fan curve is based on the H100i V2 temperature and not the CPU temperature. It sounds like your fan speeds are based on the CPU temperature. Also, keep Q-Fan disabled for the header that the pump is plugged in to. This does not control the fan speed but provides power to the pump. Disabling Q-Fan makes sure that it gets a steady and full 12V. Link to comment Share on other sites More sharing options...
DidAllCould Posted December 4, 2017 Author Share Posted December 4, 2017 I did all that and have been running it that way. I have tried to do this with the cooling temp and cpu temp. Still have that faint like pulsing in a fan or something. Link to comment Share on other sites More sharing options...
DevBiker Posted December 4, 2017 Share Posted December 4, 2017 Keep it set on the coolant temp. Can verify that it's a fan? One or the other by stopping the fans with your finger (or something else) to see if it goes away? And what is you fan speed? Link to comment Share on other sites More sharing options...
snapper69 Posted December 4, 2017 Share Posted December 4, 2017 If some of your fans are connected to the motherboard, you will not be able to slave them to the coolant temp, nor control them with Link. My Asus Fan Xpert had the facility to set a delay of 10 or more seconds, to stop the pulsing. Link to comment Share on other sites More sharing options...
DidAllCould Posted December 4, 2017 Author Share Posted December 4, 2017 I checked over all my fans after work and 1 of my top 200 mm fans was not getting enough power I think on a 2 pin system that allows me to monitor fan speed from the front of my tower. I tested it plugged into a more direct route and the Woosh or pulsing sound went away. Thanks you all for your help and ideas. Link to comment Share on other sites More sharing options...
