P03-630 Intake and exhaust upgrade FYI

Hi all, so yesterday evening I swapped out both intake and exhaust fans with the Noctua NF-A9 PWM 92mm. I'm disappointed to say I've already removed them and put the factory Predator fans back in. The Noctua fans spin at 1/2 the RPM max speed, 2000rpm vs 4000rpm from the Predators. This made for a much quieter operation but higher temps, I'd rather a bit more noise than a much hotter system.

With predator fans the system temp on PredatorSense never got past 38c while having a long gaming session of COD. Idle system temps hover around 25-30c depending on room temp. When the Noctua fans were installed I was reaching 52c when gaming on COD, idle temps were 39c. They just don't have the RPM to move the air in my opinion.

figured I'd share my findings, thanks!

Yes, most of the fan noise is from the volume of air being moved, not from the fan mechanics. A quieter fan is quieter mostly due to a lower air volume.

Thanks for reporting your results. Are those processor temps? 52*C isn't too warm under gaming loads. If coolboost is enabled, you could disable it for quieter performance even if processor temps are 20-30*C higher. Won't hurt anything.

CPU and GPU temps were higher while gaming. after prolonged gaming the RTX3070 runs at 68-72c with the Predator case fans and the CPU sits about 65-69c (CPU cooler upgraded to NH-U9S)

when I had the Nocuta exhaust and intake fans the RTX3070 ended up at 75-78c and the CPU was 79-80c

Big difference in my opinion.... I just thought the Nocuta fans were going to improve the air and heat movement in the case but most definitely did not.

the 52c is the ambient temp inside the case i assume. in my PredatorSense app i have 3 temps: CPU, GPU, & System

No coolboost button?

Nope, mine looks totally different.

Just for some additional advice, does a 1200mm fan fit? As the Noctua NF-S12B redux range is their top case fans, as they make allot of case fans (which are of premium performance/quite sound and quality) but and also you need to not only upgrade the case fans but also the CPU cooling system tandemly as to give you maximum cooling of your system while gaming, btw an AIO water cooling is also advisable but you need to measure your spaces as they are much more bulky and need more space. The appropriate Noctua CPU cooler for your desktop is the Noctua NH-U9S chromax.black which is an excellent cooler that will considerably reduce temps if tandemly used with the Noctua case fans.

A 120mm wont fit in this case. I already run the NH-U9S CPU cooler, just not the black one

I'm happy with my temps, my hope was id be able to achieve them a bit quieter with the Noctua fans. Unfortunately that's not the case because they run at a much lower RPM

Well-enough should be left alone.

Good job with the HDD tray deletion and upgrades!

I did cooler and Noctua fan swap with my PO3-620 (10400f, RTX 3070) and I also removed the HDD tray. Interestingly my temps were considerably lower than yours. Not sure if it matters, but I used metal side panel that has some ventilation holes on it.

Our ambient room temperatures may differ a bit. But some of the CPU temp difference may be caused by restricted airflow. Removing HDD tray helps, but those intake and exhaust fans are still partially blocked by metal mesh... not to forget how covered in plastic the front of the case is.

I don't recommend you or anyone else to do this, but I removed (Dremel went brrr!) those restrictive metal meshes and replaced them with finger guards. The more air goes through the case, the cooler components stay.

I believe that the CPU and exhaust fans work in tandem. Now that your CPU stays cooler the cooler fan and exhaust fans spin slower as well. Maybe you could try using Y-splitter cable and connect intake and exhaust Noctuas and adjust them via PredatorSense?

Oh, I even turned the PSU upside down so that it helped to suck hot air from the case and exhaust it out. Not sure if that makes any real difference, but at least the PSU was not sucking dusty air anymore.

The pic below is after cooler and fan swap, HDD thay and mesh deletion. Originally the CPU started to throttle... and the fans "would have" damaged my hearing in the long run. :-P
