[SOLVED] How many fans?

[Lukhino]

Hello,
i have this setup
3xArctic P12 PMW Front intake
1x CPU Coller Noctua NH-D14
2xExhaust Fractal GP-12

Have i change stock fan to another brand? (2xFractal GP12 - exhaust)
Is Arctic F12 PMW Black is good choice?

How many fans do i need?

Thank you for help.

You might need none, 1, or 8......depending on your temps that we don't know.

yeah, but i think there is a some rule how many fans do i need to use, i prefer quiet setup.

"how many" is maybe less than you think.

There is no specific number.

Case fans have but one purpose...Bring in cool outside air, exhaust warm inside air.
In the front, out the top/back.

Maybe he want to put his rig into wind tunnel for gimmick

I really doubt you need MORE fans, and I'm not sure where you might even install more. The only way to justify more would be if your system does get near maximum temperatures at very high workloads (e.g., sustained gaming). Given the good CPU cooler system, the only place I MIGHT think could need more cooling is on the mobo OR MAYBE the GPU chip on the graphics card. But I doubt even those are in trouble. Don't forget: temperatures in the 80C range at max workload are normal for many current components, so don't just freak at the numbers. FIND OUT exactly what temps are normal, and what are the real limits specified, for your CPU, GPU, and motherboard.

The replacement you propose would make almost NO difference. The max air flow ratings for those two fans models are virtually the same, and so are their pressure ratings. Max noise ratings are spec'd in different systems so we cannot compare. The only difference is that the Fractal GP-12 is a 3-pin design, and the Arctic F12 is a 4-pin PWM design. This makes NO difference in cooling capability, but does require a modest adjustment to the configuration of the mobo fan header used to plug them in.

Good as is, unless you simply feel like you need to spend money. The GP's are seriously decent for stock included case fans. The Arctic might be a little quieter at higher rpms, but require the higher rpms to push as much air as the GP's do.

If you want quieter fans replace the loud ones or tune them to spin slower. Even the quietest fans will be audible if running over 50-60%.

I'd guess in terms of the number of fans you're doing fine.

More fans equals more noise. You say you want a quote system then liquid cooling is the way to go. Even if it just the CPU that can help is more ways than you think (keep reading to see what I mean). The graphics card, with its 3 fans will be loud at full load. Getting a hybrid AIO is okay but a full waterblock with custom liquid cooling is a fun project. If you go that rout then tying in a CPU block is very simple. Then install a dual 120mm radiator up top and triple 120mm ok the front.
Note that on that case you can remove a top insert on the shroud that covers the power supply. It’s to the far right near the front fans. This exposes the bottom of the case where you can add another fan. This can be an install or even an exauhst to vent out the bottom airflow from the front radiator. With a custom loop and two radiators, all your fans can run at low speeds, to stay quite, and cool your system plenty.
One of the main benefits not at least getting rid of the giant CPU fin and heat pipe cooler is to allow better airflow to the backside of your graphics card. Even with a frontside waterblock, the backside (even with a backplate) gets super hot and puts a hurting on your memory chips. On all my systems I sit a 120mm fan right on the backplate with some two sided foam pads to act as spacers and to keep the fan in place. This alone cools the card quite a bit and with your large CPU cooler, there is no room for this. I have one system where I took an old Intel OEM heatsink and fan I have it sitting on the backplate (over the back side of the GPU and memory) and a thin thermal pad holding it in place. A second graphics card has a thermal pad and a very thin heatsink sitting in this same spot (there was no room for anything else worth the 1st graphics card sitting so close to it.
I also used the cheap pump and reservoir that is for sale on Amazon. Also a cheap copper waterblock for the CPU. I did make sure to invest in good quality radiators (copper core) and of course the graphics card block was not cheap either. My temps are very good for an i7-9700k and 2080ti’s (both overclocked) running under full load. I run Folding@Home and BOINC, at the same time. This puts the biggest load on both CPU and GPU then even mining or any stress test app out there.

May AIO (H60) was the loudest part of my system... listening to that pump droning away drove me crazy. My PC is blissfully silent after moving to a AS500 Plus & Noctua fans. At least at idle. Gaming it's a combination of GPU and case fans.

Not going full custom liquid cooling as this is also my work PC, replacing a fan is quicker & easier than working on liquid. Although it would be awesome!
