3570k Overclocked but fan is extremely loud

Hey there guys, I've only tried overclocking a few times before with my 212 evo and it's original fan and it was always pretty loud. I assumed that was because it was the default fan.

I recently bought a Noctua NF-f12 fan which is extremely quiet during normal use. So I tried overclocking again with the new fan at 4.2 GHZ at 1.15V and the fan is just extremely loud.

Without overclocking and with normal use, my fan uses 23% of it's speed(minimum because of my motherboard's Smart hardware control). When playing a game like CSGO which is very CPU intensive, roughly 40-48% fan speed is used. However when overclocking to the speed and voltage mentioned, on idle the Noctua jumps up to 40-52% fan speed. And when playing a game like CSGO, it'll jump to 80% +. Is this to be expected or is something wrong here?

If this is to be expected, should I look at another cooler such as an AIO(most air coolers won't fit because of my tall RAM) or will having a different CPU cooler not make much of a difference. I want to overclock but I also want a very quiet PC. I have a H440 case and I don't mind dropping up to $120-140 CAD on a new cooler.

Any help is appreciated, thanks.

Yes, that will probably make a difference.
Basic rule - check and optimize what you have, before changing to something new, which was not the issue to begin with.
Yeah for sure, just wanted to make sure that this much of a difference was expected considering that overclocking on idle is as if I was gaming with 100% CPU usage without OCing.

Would an AIO like an H110i V2 make a significant difference in sound if I added two Nf-nf12s?
 


Liquid coolers may be louder. More moving parts.
Fan(s) + pump + moving liquid.

I moved from an old CM Hyper 212+ to a Cryorig A80. It was a little bit louder, at idle and under load.
Of course, it ended up quite a bit cooler across all load ranges.


Also, how clean is the case and current fan filters? That can make a huge difference.
A dusty filter means the fan has to spin faster to pull the same amount of air. Often, just a good clean makes it quieter.
 


I see. I was looking at a few air coolers that seemed to be pretty good but most of them didn't fit because of my RAM. And this case is pretty new so most of the filters are somewhat clean but I'll give them a quick clean soon because every little bit helps.

So to sum it all up, it's unlikely that I'll have both a quiet PC and an overclocked CPU. It's either one or the other.

I was considering upgrading to a 6700k but trying to hold off on that since if I get a 6700k, I'll need a new motherboard and new RAM and my 3570k still has some life in it.
 
So I just realized something that may be impacting my whole PC as a whole in terms of both temperature and quietness. So my PSU has been bothering me for a while now as it's been making a lot of noise. I never really noticed it since I always had my headset on. Apparently I had my PSU fan facing up instead of at the bottom of the case where a a filter exists. So I'm pretty much taking in hot air making the fans work harder and more noise. Maybe this will make a difference...Not sure how I managed that.

Just flipped it and cleaned the front filter and it's actually significantly quieter (not OCed). Now I can't really hear the PSUs air flow however now it sounds like it's dying. Like that noise a really old fan makes, kind of a squealing. Saw a few videos saying to put some sort of lube into the fan so I may give that a try. Either way thanks for the help.
