Here is my issue. I built my own computer about a week ago. When I got it, I put in 3 extra fans for exhaust and put the 2 120mm fractal fans that came with my case as intake. The 3 exhaust fans were plugged into a splitter to the cpu fan 2 while the 2 intake fans were plugged into the the 2 fan headers on the bottom of my motherboard. The 3 extra fans that I had bought were really loud because they could spin at a high rpm. I tried to set the fan curves, but since I have an asrock board, I was limited to control my fans by percentage of the highest rpm. They were marketed as fans that could go from 1000 to a little above 2000, like 2100 or something like that. but not any more than that. When I set fan curves, you have to run a fan test. So I did and it reported back as 100% fan speed as 2666 and 10% fan speed as 1375. I figured it was the fans fault and not my motherboard, or a combination of both because I could only control by percentage. I'm going to return them. I was researching and stumbled across the arctic p12. Quiet, 120mm, $10 fans. Everyone says that they are great. So I bought them. Once they came, I swapped them out from my old fans that I thought were too loud, and plugged them back into the cpu fan 2 header since it was the only one that they could reach. Also arctic fans can be daisy changed so thats what I did. Thinking that that would fix the noise, it didn't and when I went to run another fan test to set the percentages to the rpms, and it came back with the say percentages as last time from my old fans. What do I do? Is there anyway to reset fan profiles or something? Thanks for reading all this btw. Came out to a small novel lol.
