After a coupe of good 140mm case fans

The fans arrived today and I've just installed them.

My existing exhaust fan was a three-pin, so no PWM on that, and it looks like it tops out at 1250rpm. So I shifted that fan to the uppper front and put my new PH-F140MPs in the exhaust and lower front slot.

First thing I noticed was more noise. Well, duh - I just tripled the number of case fans! It hasn't made much of a noticable difference with temperatures, though. Airflow has definitely improved, and it now feels like the air blowing from the exhaust fan is cool rather than warm. But running OCCT CPU test, my CPU temp dropped by one degree! Okay, this may be due to the stock cooler just not being able to dissipate enough heat so I wasn't overly surprised by that. My motherboard temperature in HWinfo only dropped by one degree as well, though. I was hoping for better, tbh.

New CPU cooler next, clearly. And I need to set a BIOS fans profile to quieten it down at idle.
 
Guess you still had reasonable air flow before after all
But yes not going to really affect cpu temp much if you weren't lacking air flow to a bad degree before
Or as you say you are already near enough as cool as stock cooler can do
And may depend where on the board temp sensor is for motherboard temp

Yeah, possibly so!

I can tell the air coming out the back is a lot cooler, but I guess the problems are with heat dissipating away from components probably due to poor heatsinks (I am not a fan of the plastic shrouds a lot of manufactures use on their motherboards these days) rather the case air actually being too hot.

Incidentally, what's the best way to set fan profiles these days? I've not done it since Speedfan was the go-to app. Is this best done in the BIOS? Ryzen Master? Another app? It would be good to quieten things down until the CPU actually gets decently hot.

EDIT: Nvm. I was being lazy (again!). After posting I decided to just got into the BIOS and set a fan profile. Ahhh. blissful quiet now when on the desktop. :)

Speed fan may still work not tried it in ages
I prefer software as can adjust on the fly as you see/hear what happens when you do stuff
Rather than constantly rebooting to bios making adjustments
Depends on whether motherboard software is any good
This is my first gigabyte board in years and the software isn't reporting 3 of my fans/pumps at all
Yet in same software in alert if a fan/pump fails section it reports them all fine
 
After a bit more monitoring, one thing I've noticed that's really pleased me is that, whilst load temperatures haven't fallen markedly, the idle temperatures of my CPU and motherboard have come down - even when the fans are spinning more slowly.

I'm now using the PC with Chrome and Word open, with idle temperatures (slightly) lower than they were before but with the case fans now all but inaudible at 550rpm. All I can hear is the whir of the CPU fan (which makes me want to grab a better CPU cooler, of course...)
 
Yeah grab a better cooler
Or if the fans replaceable on it do that
Not used stock coolers in years
So not sure if it's a fan that's different from standard
So if it's a weird shape or mounting etc
Just ignore me lol
 
Just to clarify, you got PH-F140MP fans? And after adjusting temp/rpm profile system is running cooler and quieter than before?

What case, motherboard, RAM and CPU cooler do you now have?

Yep, got two of them, put one in exhaust, one lower front intake and moved existing three-pin exhaust to upper front intake.

It's only quieter because I actually bothered going into the BIOS and setting up a fan profile since without it the sound of the three case fans was too much for desktop use.

The temperatures with this fan profile are (very slightly) better and the noise profile much quieter than they were with just the single exhaust spinning faster.

I have a Phanteks Enthoo Pro-M and running the stock CPU cooler on my 2600X. The CPU cooler is now the only thing I notice the noise of with the PC under my desk and about 60cm off to one side.
 
Bit of a thread bump. I needed some new case fans for a new build, was contemplating the Noctua's, but budget prevailed. Ended up grabbing the twin pack Phantek 140MP and Phantek 120 MP. £16.26 for the 2 140s and £14.99 for the 2 120s. They replaced some aging NZXT 3pin and Fractal fans from 6 years ago.
 
Used the Arctic before, 10 of them, replaced by the Phanteks. The only difference, as ar as i can tell is the Phanteks is slightly quieter at full blast, but don't run them past 50%, so no difference from the Arctic.
But don't think the Arctic are loud. They aren't. And you can daisy chain them easily. Cleaver design.
