I’m really new to building pcs but my fans are loud as hell
Are these fans good good or are they just break the bank good
Yes they are really good.
However consider the totality of your noise footprint when setting your expectations. I started with quieter case fans, which allowed me to hear how damn loud my cpu cooler was. Replaced that with a Noctua, and that alerted me to how loud HDDs are and how often my psu fan kicks in.
My case now has zero HDDs, all Noctua fans including CPU cooler, and a PSU that will stop spinning completely if temps drop below a threshold.
If my fans don't spin up over 50% I cannot hear them. It's great.
I use two server Fans to cool practically everything, Without headphones, there is nothing else to hear other than them, but active noise cancelling is magic and now it is completely silent, as your setup.
Lol
Look at Musk over here, affording multiple Noctua fans.
Out with the old, in with the new! My Noctua fans are now known as X fans.
my grandpa worked in the mines, for months on end, just to afford a single 80mm noctua fan! You don't appreciate hard aerodynamics!
I swear by my Noctuas, they are fantastic fans. I've had a full set of them in my case for about 8 years now, even under heavy gaming load the fans will get more 'whooshy' but they are hardly noticeable and keep the system cool.
How much did they run you? My case came with four pre-installed fans and I purchased an additional three (only two can fit in the case though). I’d be willing to swap them out if they make that much of a difference while still providing cooler air than what I currently have.
In most instances, a Noctua fan should outperform the majority of fans that come pre-installed with your case.
If your fans a plugged in via molex see here, then they won't be controlled by the pc and will run at max speed. If your fans are all plugged in via the motherboard they might be loud or the fan speed is too high. You can make them run slower by adjusting the fan curve, of which there are instructions on Google.
I’ve adjusted my fan’s curves via BIOS—but I am really paranoid as this is my first build and figured that when it gets to above ~45C they should increase in speed. I do a lot of 3D rendering, not so much gaming, and my CPU and GPU usually average between 50-60C when I do this. Would lowering their speeds be detrimental to my mobo or components? 🥲
50-60C is still way far from the danger zone. You're not going to run into issues unless they're pegged closer to 100C for extended periods of time, and even then your PC is more likely to shut itself down to protect itself than kill itself.
Edit: not that you should run your PC at 100C. Anything below 90C and you're almost certainly not going to run into any issue other than loud fans.
Thank you so so much for the reassurance. I’ve really been freaking out at every temp spike thinking it’s gonna spontaneously combust. I didn’t give a shit about my prebuilt lmao but this one is my baby 😭
My cpu runs around 58 when gaming. That's fine, my hot water from the tap is that temp.
They are very good, but there are also a bunch of different models that are very similar but are not the same. So you might want to do some reaseach on what your needs are and thus which type of fans you need.
This ranges from ones that have different speeds and different noise levels, all the way to fans that are designed for airflow(ex: normal case fans) and ones that are designed for air pressure(ex: blowing through a radiator). And they can be noticably different if used for the wrong thing.
Also check which fans are making the most noise. For example the case fans might mostly be fine and swapping the CPU cooling fan(s) could fix it.
Although it's important to note that GPU fan will pretty much always be loud under load unless you go water cooled. And even then you'll hear it when things heat up.
Just hook your watercooling up to the AC system. No more sounds from your PC ;P
They are good, but definitely noticeable above 45-50% speed.
If your fans are loud as hell albeit non-critical temperatures, you probably didn't adjust your fan curves.
I’ve adjusted them, I think I’ve just been working them to death. My area is also going thru a heatwave so the ambient temperature in my room is also quite warm. I’m not sure what else to do but as long as it’s safe I can deal with the noise.
