Hello all,

I'm looking to quieten my gaming PC down without causing thermal issues.

My system is the following
5800x
3070 ti FE
Phanteks 750 amp (hybrid mode)
EK 280 aio cooler (fans set to 1000rpm)
Lian li lancool 215 stock fans

My PC is not exactly loud, I can hear it over my headphones (g pro X) so looking to improve it.
I have looked into custom watercooling, which I may do CPU only next year.
I'm wondering if changing all the fans in the system will help? So replace the two front 200mm with three 120's and then replace the rear 120 and two 140s in the roof also.
I quite like the new bequiet light wings.

Any opinions or advice?
Case change?
Thanks

Are we talking noise under load or idle ?

Surley the bigest noise under load is the gpu and psu.

If I'm honest, it dont get louder under load, just has the same sound at all times.
I've looked at maybe changing case to a p500a and running 140mm light wings all round

What's spoeds are the 120mm and 140mm fans running at and Are they all the same fans ?
 
So the top 140's for the aio are the EK Vardar fans, they are set to 1000rpm fixed
Both the 200's are 800rpm fixed (stock case fans
Rear 120 is 1100rpm (stock case fan)

Disconnect the 120mm see of its causing the problem if its extracting then if mite be worth changing to an intake .
 
For silence, the only custom watercooling worth doing is the GPU. Unless hammering the CPU, for the average user, a Arctic Freezer II or a Dark Rock Pro 4 will be virtually silent. The issue is the GPU, which under load will be louder than any decent CPU AIO or Cooler.
When I mention the Arctic Freezer, isn't just performance, but the pump design is great. No noise, no high pitch like I had with Corsair, and I believe plagues most AIOs.
Alphacool had an full block AIO for GPUs.

Sorry been busy haha

Ok will try that soon and see what difference it makes.
My PSU is a seasonic made unit so assuming that shouldn't be the issue, and my 3070ti never exceeds 74-75c and I'm positive it's not the GPU fan
 
Big fans shift the same volume of air at a lower RPM compared to smaller fans. Which also comes with the added benefit of producing less noise.
Switching out 2x200mm fans for 3x120mm is going to either reduce airflow, or increase noise to keep airflow the same. The same will happen swapping 140mm for 120mm as well just to a lesser extent.

It's going to be either the FE cooler is allowed to do what it wants which is not that great noise wise above 60%. Or it's the Vardar S fans which I'm looking to replace on my AIO with Arctic P12's.

I'm thinking it's the vardar s fans and the rear 120, going to try unplugging to found out soon
 
How loud is the PC in bios compared to sat in Windows? My FE fan is idle in bios so any noise the system is making can only be CPU/Chassis fans, and if you adjust the fan curve in bios you will get the nosie changes instantly without the need to unplug anything.

I wouldn't replace any fans.

I would have a look at your temps under load. There's a good video from Jay on this recently:-
https://youtu.be/AkNEvIWp2fM
TLDR is run Heaven and Cinabench on multicore CPU whilst looking at temps in Ryzen Master and MSI Afterburner for a minimum of 15 mins.

Once you know your temps under load you then know how much thermal headroom you have to slow down your fans (assuming your fans are making the noise, if it is coil whine or spinning hard disks or something else we'll need to take another approach).

Now check if your fans are plugged into your motherboard or not. If not, maybe they are plugged into a fan controller that is plugged into the motherboard? If this is the case and we're unable to solve the noise in basic troubleshooting we'll need to check that all cables and connectors are working as a fault may cause a fan to run full speed all the time. If you have have fans that are not plugged into the motherboard (either directly or via a fan controller) see if you can't fix this.

Now check your motherboard manual and make sure you didn't use the AIO or Pump fan header from the motherboard as this will always run at 100%.

Now head into BIOS and see if there's any fan tuning software. What make is your motherboard? You may be able to see all the fan RPMs. Here you can try tuning your fan curves and the go back to stress testing.

Let us know how you get on.
 
Sorry for the late reply all!

I've decided to change case after seeing the 011 mini air haha

So going to buy one of those and kit it out with the new bequiet light wing fans.
Only issue is I will to move my 280 aio rad from the roof to the front, do you think this will cause any issues for my 3070ti FE?
I will have the bottom front and side fans as intake, and the rear and roof fans as exhaust.

So will have 2x140 in front (intake)
2x140 on floor (intake)
2x120 on side (intake)
2x 140 in roof (exhaust)
1x 120 in rear (exhaust)
 
Wouldn't it be better to keep 280 AIO rad up top with front and bottom having 140mm intake fans? Would help to use taller feet so bottom of case is about 50mm above what it sets on. Gives much better airflow to bottom intakes (3x 140x50mm=21000sqmm airflow area into 140mm fan with about 15000sqmm airflow area. Stock feet give maybe 20mm of airflow, so 3x sides times 20mm=8400sqcm of airflow area into 15000sqmm of 140mm fan airflow area. You can see how more is better. ;)

With 4x 140mm intakes and 280 rad in top exhaust you wouldn't need any other fans. The 4x 140mm intakes will just flow the air not being used by rad on out thru case's other empty vents.
