[SOLVED] Fan curves for AIO

[Bob1nba]

I installed 3x 120mm lian li unifans on my kraken x73 aio. I know lian li has software to control the fan curves and rgb, I just have never really set fan curves before so im not really sure what I'm looking for.
I top mounted the aio in the case so the fans are exhaust.

Run the fans at full blast while running a CPU performance test (Cinebench, or go find a long video to crunch with Handbrake), wait for the temperature to stabilize, then start lowering the fan speed until you can tolerate the noise. Set that as your upper limit. Then adjust it from there. Most CPUs I'm aware of have a temperature limit of 100C, so as long as you're not hitting that, you're fine. Though personally I will start worrying if it approaches 90C.

You can also use Prime95, but it isn't a realistic workload in most cases so using this may cuase your fan curve to be too aggressive.

Although there's no "one fits all" solution. I always et them so they run lowest possible speed at idle temperatures and straight line up to maximum speed couple of degrees before maximum allowable/desirable CPU temperatures are reached.
Reasons are that fans are not very finely adjustable and few hundred RPM + /- doesn't really matter. The other reason is that fans are there for cooling and only cooling. If they are too noisy, too bad change fans or complete cooler to something quieter, or adjust CPU performance to run cooler. Both of those conditions are better than risking malfunctions and overheat problems.
