Hi

My fans (cpu fan i think) ramps up and down all the time, even when i do things like open brave browser.

Anything i can do about this?
 
Most likely the CPU is going from one fan speed profile to the next one, it cools down so fans ramp down again, heats up fans speed up etc

I'd set a slightly higher fan profile, that way it'll just less amount of fan ramping
 
Sometimes you can set a delay to allow the CPU enough time to boost up and down for a short period, but the most obvious fix is just to increase the fan curve high enough that it only kicks in when you're under sustained load.
 
Would ask what the idle and load temps are

The higher the delta the more a fan profile become relevant

If however your idle is high implying that your delta is small then fan profiles are little help as the problem lies elsewhere
 
just to jump in on this discussion i have just upgraded my pc to a new case and aio cooler (a lian li lancool 217 and a arctic liquid freezer 3 pro 360mm) my fans had the same problem as the Op's I used Asus Fan Xpert 4 to alter the fan curves and managed to stop the fans ramping up when using the desktop eg.opening the browser and other tasks,
now i find when i am in a game after a while the fans will ramp up again which is very noisy, I have tried allt & tabing out of the game to alter the fan curve straight away but i have not been successful yet finding the right settings. never had this problem before so any help/advise welcome.

what curves did you set if you dont mind me asking?
 
Depends on your controller, but you can set hysteresis; if your fans are tied to a component which rapidly spikes temp, eg a cpu, a blip of activity causes a jump of say 10 to 20C, and the fans immediately adjust based on their curve, hysteresis smooths this out and prevents sudden jumps.

Some software let's you set a delay, it's a bit more rudimentary but the effect is similar; fan curve doesn't adjust until that temperature spike is sustained for more than a second, or whatever you set it to.
 
my curves are like this at the moment
asus hydronode set to on
ai cooling ii set to on

cpu fan 60/0% 75/20% 80/50% 90/100% (first Number Is degrees celsius)

chassis fans 60/20% 75/20% 90/20% 100/40% (all five set the same)
 
As far as I remember
Asus hydranode required very specific fans
Not sure i ever found any of them
So dont expect any benefit from having hydranode on
I just leave it disabled
