Computer is too Loud

[adgjk]

Hi all, 

 

I'm not really sure what to do... My computer sits about 2-3ft away from me on top of my desk. It was a loud little beast before, then I spent money upgrading it a little - I got a new CPU cooler, new case, new PSU... All in effort to make it quieter (and help future expandability, my original case was cheap and hard to work in). 

 

It's still a bit noisy though... I used a dB meter on my phone (not the most accurate, I know) but it's coming out at about 40-45dB in a quiet room (which is usually 25-30dB). There are 5 fans inside the computer, all stock Corsair AF140L, 3 of which came with the case and 2 with the CPU cooler. CPU cooler is mounted to the top, another 2x140 in the front and 1x140 in the rear. On my motherboard i've got them all on a "silent" profile, although i don't think it actually makes a difference... I'm assuming this is the motherboard's fault though. It's not a particularly good one - I've learned a lot more about computer parts since I bought everything back in September... 

 

I just don't know what to do... It says that my fans are running around 600rpm, so i thought that'd be barely audible. Apparently not... Would replacing to all Noctuas change this? I'm kind of reluctant to do that considering it would me about £100+ to do that... 

 

Advice please!

i would get be quiet silent wings 2 (or 3 when they come out)

BTW Stock corsair fans are really bad (and load) so i would change them all out for be quiet fans

Perhaps I should wait until November for the BeQuiet Silent Wings 3? Still expensive though...

Must've been typing as you posted, sorry. Thanks for getting back. That's good to know that they're known to be loud, but at 600rpm...? Is that right? I just figured they're big and spinning slow, so they'll be really quiet, but apparently not... Should I replace the H110i GT fans too? I've seen a lot of people asking, but generally Corsair are telling people to stick with stock, because they were designed for it (not even telling them to go for their more expensive after market fans)

i would replace them too (remember to get PWM fans for the rad) Corsair stock fans are just plain shit when it comes to acoustics so i would think that's normal.

i kind of regret getting corsair fans for the rad and exhaust since my silentwings 2 in the front running at 100% (1500rpm) is as noise as corsair fans running at 400rpm (i bought the corsair's because of looks) but don't get me wrong, the fans corsair sells standalone is much better then the stock ones but still.

Wow, that's impressive, and completely stupid at the same time! How can they be made so badly??

Now, for even more money (IF I get it, although I suppose this could be an upgrade to be done at an even later time), is push/pull worth it? 4 fans at lower speeds, or is that just more for looks/bragging rights?

they are not that bad, the corsair fans (non stock) is better then most fans on the market, it's just the be quiet fans that are really good

I have a mitx system that was about 40-45db which bugged me. I ended up taking out the hard drive and putting it in a external enclosure with a power switch, putting a nf-a14 in the psu, putting a nf-p12 on the front for the h55 rad, putting a low noise adapter on the h55 pump, and I took off the GPU fan and shroud and put a case fan at low rpm right on the GPU. Now it's quiet.

push/pull is not worth it i would say

Now I like the sound of this, but it also slightly worries me that it could damage something down the line... Is this common practice? And which LNA did you use?

Nope, not common... I used one that came with a noctua fan. It makes it run at about 800 RPM when I think it ran at about 1600 before. Only go for this if it's the loudest thing in your computer. The way to make it quiet is just replacing only the loudest things till everything is quiet.
