I’ve been active the last few days with a few posts and I appreciate everyone’s help and input. I’ve been learning a lot delving into things I normally haven’t had to deal with in all my PC builds over the years.
I finally got my thermals under control with my 3900x but had a general question when it comes to setting fan curves. My Radiator fans and case fans constantly would rev up and down based on CPU temps. I found this to be quite annoying so I went in and created a custom profile for both my Krakken X63, The Radiator Fans, and my 6 case fans.
My goal was to keep it as quiet as I could while still maintaining the best performance. It took me awhile to find the sweet spot, but I think I landed on custom profiles that work pretty good. I would like some advice or input if I’m setting it up correctly.
Adjusting my Krakken X63 I found that putting the Pump on Performance provided the best overall noise to performance ratio when paired with a custom profile for my rad fans. I had the hardest time adjusting the rad fan curve; it would fluctuate all over the place. So instead I set the fans to a fixed 1200rpm, if the CPU reaches 70c the rad fans goto 100%. My corsair ML120 case fans I had a way easier time setting the curve. I found the most important spots to fix the revving up and down was adjusting the curve between 40c and 70c. I basically have the fans running slower than default at each point on the curve until about 60c. I basically have my rad fans and case fans waiting a little longer before they start increasing in speeds. So far Idling, Web Browsing, Gaming, and full loads hasn’t changed much in terms of thermals. I would say I’m giving up maybe 4c-5c under certain conditions for better noise levels. This I am fine with since even under 100% load I’m never really going above 70c. In order to maintain these curves I have to have the pump set to performance which is near it’s max, but oddly quieter than I thought it would be.
So my question, should I have not adjusted these curves? Is it not recommended? The default curves had everything revving up to 80% at around 55c which to me seemed like overkill albeit with 5c better thermals, but at the cost of noise. I just want to make sure I’m not doing something stupid.
