i downloaded command centre for my pc (msi b450 tomahawk) and have been monitoring temps, at the moment all my fans are 3 pin but for some reason i can still control them, not by much it would seem

im replacing these fans with noctua pwm fans which i have ordered (2x 140 + 2x 120), ive been playing about with the system fan settings, my layout is 2x 120 intake and 1x 120 rear and 1x 120 top exhaust, by increasing the rpm of the front fans (1000rpm) and the rear (600 rpm) ive noticed the cpu temp drops which can only be a good thing, its pretty audible but when the noctuas arrive that should be fine, the case is a meshify c and i was just wondering if using this software configuration is advisable? setting the intakes to higher rpm than the rear and top?, the front fans have a filter, the software seems to the best solution for case fan control i think, should i also let the cpu run on smart mode rather than playing around with the fan configuration, ill also be replacing the cpu cooler with a 212 evo, its currently running the wraith spire (2600x), im guessing the 212 will do a better job straight away

Thanks
 
First, don't use command center for monitoring on Ryzen. Download and use Ryzen master. There are good reasons for this including offset issues generally not incorporated into many of the other monitoring utilities. Ryzen master and Core Temp are pre-offset. Others are hit and miss.

Fan controls should be done through the BIOS fan control settings UNLESS you have all fans connected to a dedicated third party fan controller. Even if you have an integrated hub that came with the case and connects to a single motherboard fan header, the controls and settings for that header should be managed in the BIOS.

Good deal on the Noctuas, which models did you go with?

Setting the intake and exhaust equally generally provides the best balance of performance and dust suppression, and I like to see a fan curve that starts around 20-30% PWM signal at the low end, gradually increases to about 50% at 65°C and then quickly starts ramping up so that by the time you are at 75°C all fans, intake and exhaust, are at 100% PWM signal. Or if it's a DC controlled setup, a similar configuration.

The CPU cooler fan can pretty much be set to a similar curve, and you can play around with it to find what works best for you based on what you do and where you tend to "live" in terms of peak thermals. You don't want to see CPU core or package temps in excess of 80°C under full load, so make adjustments that take that into consideration based on what you see happen under those conditions.

I'd forget about the 212 EVO unless it's the only decent budget option you can afford or is available to you in your region.

How much can you actually afford to spend on a CPU cooler? Do you plan to overclock the CPU?

How many DIMMs (Memory modules) are you running? What is the model of your memory kit?

Thanks for your help, it's the noctua NF-A14 and nf f12, mostly bought them because they are a tried and tested fan, I don't really plan on doing anything heavy with the PC, overclocking etc, it plays games just fine so that suits me, I just want to be able to maintain temps and the 212 would be fine for my needs, water cooling could be something I do at some point In The future, I'll have a look at the fan control via the bios, I'm just not really sure which would be the best fan curve, the pc is located in a small room that can get hot in the summer, no pets, I have 16gb ram corsair vengeance at 3000mhz
 
So, that's all good. The fans are excellent. I run exclusively NF-A14s in my system.

Memory configuration is good as well. Not going to add a lot of extra heat or voltage.

Your 3 pin fans are likely controllabl because your motherboard has the ability to switch between PWM and DC controls. It would be recommendable that until you do replace the fans, and after doing so, that you go into the BIOS and find the fan control settings. Change them to DC control for each fan that is connected if they are currently set to PWM. They may already be.

Once you install PWM fans, be sure to go in there and change them to PWM controls. As for the fan curve, I loosely outlined what I think is a fairly quiet yet capable curve above. Each board and BIOS have somewhat different methods for control in the BIOS but overall they are primarily the same. If you don't want to be bothered with setting a custom curve, you can select one of the preset curves in there. The silent or standard preset fan curves are probably fine for most people.

As for the cooler, if you really wish to keep it cheap, and simple, the Deepcool Gammaxx 400 is a much better choice than the Hyper 212 EVO. Not only does it outperform it but it uses the stock backplate and mounting bracket so there is no need to change the backplate out like on the 212 EVO, which might be a real pain if you have no cutout in the motherboard tray under the socket. For a cooler that performs better, and is easier to change, it's a better choice.

If you don't mind spending a little more, this cooler, while it will require changing the backplate, is far superior in terms of quality and performance.

Fantastic write up really appreciate that, I have had a look at the last cooler you recommended and think I may be convinced on it, I suspect overall the cooling will be better after installing everything, I'm just wondering how the gpu will be temperature wise, that's a sapphire rx580 8gb nitro+ and runs kind of hot anyway I believe, usually taking readings of about 75c with the current cooling method
 
And you are using only the stock fans that came with the Meshify C?

Then here's what I'd recommend for the best combination of balance between cooling, noise and dust suppression.

Three NF-A14 fans. Two in front as intake, one in the top rear position as exhaust.

One NF-S12A in the rear as exhaust.

But, that's a chunk of change at almost 100 bucks for four fans. If you're ok with that, then you pretty much can't do much better than this arrangement.

More than enough to keep the CPU cooler fed and the GPU card as cool as possible.
