Phanteks P360A 2x140mm intake vs 2x120mm intake improvement.

[Dukesilver27-]

Hi All, as the title says, would 2x140mm improve the cooling (whether it is a worthy purchase), relevant parts concerning cooling:

Case: Phanteks P360A

CPU: i5-12400 with ID-Cooling SE-234 ARGB

GPU:

Asus TUF RX 6800 XT OC

UV -125mV

OC Clock speed 2525 MHz and 2150 MHz VRAM

Slightly aggressive fan curve

Case fans:

2x stock intake fans (max 1600 RPM)

1x 120mm (max 1200 RPM) back exhaust

1x 120mm (max 1200 RPM) top back exhaust. 

Aggressive fan curve.

 

Stress test with CP 2077 ultra preset:

CPU max 61C with 60% ish utilization

GPU max 82C (hot spot not edge temperature) with 98% ish utilization

 

The 140mm fans in question: Cooler Master Masterfan MF140

What 140mm fans? Thats the main thing here as every fan performs differently.

 

Whats the current issue? What runs hot?

 

Since you have a 240mm aio I assume that is at the top? If not and you want a cooler aio and cpu simply putting the aio at the top as an INTAKE and putting the 2 120mm fans at the front as an intake will greatly improve airflow

Sorry, the fans in question is Cooler Master Masterfan MF140.

Those arent better. Id just reposition your cooler and fans. Its just a case of changing the way air flows in your case

I don't think swapping 2x120 case fans for 2x140 will have a huge effect on thermals, it can be more useful to have them get same thermals at reduced noise levels imo

Your CPU temps are ridiculously low already, my 5900X idles at 45C on watercooling 

But I'm a bit surprised by your 6800XT temp of 82C, it's not worrying but high, is that due to OC ? (I don't know much about AMD GPU OC)

Try losing the top exhaust fan and see what happens. It could be exhausting some of your fresh intake air before it can be useful.

How would you change it?

The noise doesn't really bother me, my AC is much louder than the PC fans lol.

The GPU temp is the hot spot/junction temp, but the max edge temp is 62C. OC no OC barely change the temps, unfortunately.

The top exhaust actually does better than the back exhaust, a bit more hot air flow came from top fan than the back fan.

As I said. Aio at the top as intake and the other 2 120mm fans as front intake.

Ah sorry, I actually don't have AIO, the CPU cooler is an air cooler.

Anyway, does top + front intake configuration only work for builds with AIO?

Oh no that woulf have been the better option if you had an aio.

 

With just 2x120mm fans its best to have them in the front as then both cpu and gpu get fresh air pushed to them

Ok, then all is good ! I thought 82C was the GPU temp ...

Really then you don't need any improvement

Yeah I suppose, the thing is, I'm mining when I'm not gaming, so about 19-20 hours a day.

Trying to make back the cost of purchase with my free electricity.

 

I thought improving case air flow might ease the GPU fans' burden, therefore preserving the GPU fans and the GPU itself. I suppose there's no way to increase the airflow unless I get a decent 140mm fans.

 

Thanks anyway.
