Corsair h110i GT fans 'surging' while playing games

[gailjon]

Hi,

My H110i has been faultless for the past almost five years until just recently when the fans have started ramping up, then slowing regulatory while paying games.

It normally is set with a custom curve on Corsair Link so that there is a gentle progression of increasing fan speed and all is usually well.

Thinking that it might be a software issue I have installed iCue and set a custom curve with the H110i temp as the sensor.

No luck, as soon as I start playing COD, for example, the fans start surging.

It is really annoying and, as the past five years have shown, completely unnecessary.

Any ideas? It doesn't do it when I am not playing games. Is the H110 on the way out?

They are getting to around 45 for cpu and 70 for gpu (2080) when the fans start ramping up and then down.

Sounds like they are in pwm temp mode.

Ah, I will look at bios and see what it syas

Okay, so I went into bios G fan control and changed to Dc from PWM. I will see what happens.

So hold on your cooler fans go faster when the CPU is under load ? mine do that too,then when the CPU is no longer under that load the fans slow down again this happens on and off throughout the day for me .

It's not that they get faster under load, which is normal, it is that they suddenly increase their speed to max and then decrease their speed in around 2-3 seconds. It seems that they are 'pulsing' when under load, which they have never done before.
