Case fan too LOUD!

I bought a CM JetFlo 120mm case fan and installed it today as a exhaust fan. I put a 19db adapter on it, but it's way too ***** loud! Before that I could barely hear my PC when I turned it on and didn't play any games or watch videos on youtube.

Like all I hear now is my case fan which is really annoying, I could stand it if it was like that during gaming, but not when my components are sitting around 20-30°C...

How do I make it quieter and spin less while not gaming, IS it even possible to do it with adapter that gives me a fixed speed? Without the adapter that things spinds like a plane for 3 seconds and then stops for 1 second and so on...

Is it safe in the wires are hanging between CPU cooler and GPU?

Also, I don't think that it shows up in HWMonitor

Either buy a Quiet fan, or use a fan controller to control the RPM of the fan. Depending upon your motherboard, you may be able to use an on-board software controller like Asus Fan Xpert 2. It will control both 4-pin PWM fans and 3-pin fans.

I went to UEFI and set chassis fan control to Silent Mode and it lowered sound quite a bit, but it's still somewhat loud. Problem was that it was spinning at 100% all the time I guess

I guess that I can't use manual settings in BIOS while I have a 19db adapter on it? It's set to 60% min AND max speed. When I change those settings they set back to 60%.

The main problem is that you bought a 36 dBA fan. If you want a quiet PC, then buy quiet fans (> 20 dBa).

If you are controlling the RPM, then you don't need the adapter (it just reduces the voltage going to the fan).

I'll just remove the adapter and configure fan speed settings in BIOS. With the adapter its always spinning on the same level which is fine for gaming but not while i am browsing internet or listening to music.

It sounds like a plan.
