Question Is 10sec response time too much for fan speed control?

My vent has been revving and it's annoying. Most people say that hysteresis 5'C and response time 5sec will fix this. Mine is still revving though. Now I've put the response time to 10sec and it's good. Just not sure if such a big delay is recommendable. Though logically thinking, my cpu won't catch fire within 10sec, especially not if it never goes above 70'C anyway. The curve goes from 30'C and 30% speed to 70'C and 70% speed where each +5'C increase the speed by +5%. I'm pretty happy with the results (even got 3'C less than before on the Throttlestop stress test). But I gotta admit that I don't know much about tweaking fan curves, so I'm here to ask if you guys think that this is ok.

I don't think it's too long. If it is, you have bigger issues.

This sounds like a CPU that experiences periodic temperature spikes, which are normal since idle tasks cause the CPU to boost hard.

Cool, thanks man! It's actually an intel stock cooler, so that explains a lot. But with the fan curves and undervolting I did recently, my i5 9400f runs 4k high settings Shadow of Tomb Raider at steady 60 fps, no revving anymore, temp around 45'C except for those super crowded missions where it hits 60'C. So the stock cooler does a decent job after all, makes me even doubt my decision about replacing it. 😄
