So I was given a pc and I am upgrading it, it's an MSI b75a-g43 motherboard. I have installed some stock fans and plan on changing the heatsink because it has a heatsink with no fan attached to it. There is a four pin fan connected to the case and plugged into the CPU fan port Should I change this? The room gets very hot. I am not sure if the computer was overclocked so I reset it to default via clickbios2. I intend on upgrading to quality fans in the near future. What I need help with is how can I make the fans quieter? They keep getting louder then quiet. I tried adjusting the fan setting in the bios and I am still having issues where it makes out the fan speed. I'm trying to make this build as quiet as possible. If I do much as open a browser the fan speeds max out. I've updated the drivers and I am unsure what else to do. I installed a gtx 1050ti in the build but it also has a hd7770 in it, I removed the hd7770 and it does not want to go past POST until that gpu is reinstalled. Also could someone tell me if the fans smaller than 120 mm fans are notoriously louder it seems to be something I noticed. Any help is deeply appreciated.
Thank you
