Hi all,
Just got myself a Ryzen 9 7900x and my temps fluctuate a lot. Like, a whole lot...
When gaming it spikes between 45 and 82 degrees, I know, it's not pushing 95, but still. Quite annoying as all of sudden my pc sounds like a hurricane.
FANS AND DIRECTIONS
Bottom 3 x 120mm unifan PULLING COLD AIR IN
Side 2 x 140mm unifan PULLING COLD AIR IN
Top 3 x 120mm uni fan (Lian Li Galahad 360) PUSHING HOT AIR THROUGH RAD
Back 1 x 120mm uni fan PUSHING HOT AIR OUT OF THE CASE
Any ideas on how to resolve this 'issue'?
Solved! Go to Solution.
I'm sorry, but with that kind of fan placement its not just the sound, you really have a hurricane inside your case.
Here are some takes for you.
FIRST
You have those fans for style and you are unwilling to remove them.
If so, keep INTAKE/EXHAUST fan curves flat at low to mid rpm without ramping up to avoid air turbulence. Adjust only the Radiator fans plus pump. The latter is much more important.
Offset Undervolt or Curve Optimize (or both)
SECOND
Remove the side fans that are probably blasting RGB and change it for a RGB panel if you really want to keep the color going.
Adjust the fan curve slightly on the INTAKE Bottom fans and, keep EXHAUST fan at minimum so it won't steal the radiator airflow.
Offset Undervolt or Curve Optimize (or both)
THIRD
Keep everything, make a flat fan curve at low rpm and set ECO MODE 105.
You will loose a bit of performance but you can get it back (and more) with...
... Curve Optimizer!
Another thing to keep in mind
Did you changed the stock radiator fans? Make sure the new ones are good at Static Pressure, Airflow focused fans are much worse moving air through lots of fins.
Airflow best scenario is something like this:
This is an old photo with the Ryzen 2700X but the difference to my actual is the 240 Water Cooler keeping the 7950X really cool.
Good Luck

Thanks a lot for this!
Using the curve optimiser brought them down to 40-50...
Any chance you know how to set the CO mode as default start-up?
Kinda lame that you have to reboot your pc to get into the mode you want to.
Or can't this be done? Searched the web, but found no direct answer to my Q.
Kind regards
I have set my Curve Optimizer in BIOS.
