4 case fans - what do I need and where?

Wouldn't consider overclocking unless you really want to push the limits of your gpu but there are plenty of guides if you wish to.

Fans get the p14 pst I mentioned for the front and then you can connect to your motherboard. Some motherboard and software will let you choose which sensor you can link the fans too but again research is needed, bit it's fine running of cpu temps if your fans speed are set correctly.
Do you have an opinion on the Phantek F140M25? They're new for November 2022 and I can get them with free shipping. I was looking through the Phantek products as @bimbleuk mentioned Phantek SK's yesterday.

Do you have any experience with Phanteks M25 140mm fans? @bimbleuk mentioned Phantek SK's yesterday and I think these offer much better value for money than anything else I can see. They'll cost me £39 for a 3 pack with free shipping from OCUK. I'll use two at the front and one as the top exhaust and re-use one of the stock case fans for the rear exhaust. My spare extra stock case fan will make a great discussion piece for guests, I'm sure.

No experience but seem good for the money and you should be able to connect them to a argb/drgb header on your motherboard which you have 2 of them

2 x AURA Addressable Gen 2 header
2 x AURA RGB headers

Awesome, thanks. I'll get to buying them on Monday unless anyone else on this thread has opinions or concerns.

I appreciate your help @mickyflinn. Also thanks to @bimbleuk and @Haz123. You're all awesome.
 
This has been a very informative read, thanks for posting OP. I'm in the same situation of replacing stock fans and may follow your lead with those Phanteks.
You have the b450 tomahawk which doesn't have an argb header , you will either need a fan hub or get rgb fans.
Correct, but they do a white and a black version (that's the link for the 140mm black ones) without RGB for £10 less with the 3 pack, or £3 less each with the singles.

I know I said I don't care for RGB, but then I thought "Why not?" with those fans - as the specs are the same with or without and it's just two hours overtime for something slightly nicer.
 
Phanteks are good value and I've built several P500A cases with them recently.

Phantek to use a non-standard RGB connector witht their fans but the triple fan pack comes with an adapter to use the standard 3 pin ARGB 5V connector. So you can daisy chain the Phantek fans together and plugin to a single 3 pin ARGB header or buy the Phanteks Digital RGB fan controller at ~£22 if your motherboard doesn't have one.

The SK fans are good free flow case fans. The M series would be better for mounting on air and water coolers.

Thanks for the advice again @bimbleuk, but how do I go about deducing if fans are designed for cases vs coolers? All I can see is that the SK's are worse than the M25's in nearly every way:

All I can see is that the operating voltage varience, mean time between failures & fan weight is better on the SK's. I'm not sure how to interpret cable length, but 5.5cm of cable should be pleanty (P.S. WTF do they mean by 21.65in? That's 55cm! Did nobody proof read it?!)

The promo images for both even show them both case mounted (though I do understand it's easier to market RGB fans in a case than on a cooler). What am I missing? What's the secret?

The flow figures are not reliable because there's no standard way to test fans. Having said that as you are comparing 2 fans from the same brand looking at the max air pressure that's the biggest difference between them.

The SK do look more like a general fan which could work on a cooler and as a case fan as the blades are still quite swept. The M series have a bit more aggressive fan blade profile and probably a stronger motor.

Look at the Corsair AF series fans and you can see the smaller blades with less sweep and bigger gaps which moves more air in a case position.

I can see a clear difference between the fans (left is SK's, right is M25's). They both have equal blades, on first glace I thought that the SK's had more triangular fans because of the smaller stem diameter, but I'm second guessing that they're equal. The SK's seem to be closer together and have a more swept appearance though, no need to second guess? I'm not trying to criticize, just trying to learn. Apologies for being a pain. I appreciate your help.

These days it's getting harder to tell them apart due to better design and consumer understanding. I hadn't really looked at the M series and assumed it was a high static pressure series but as you say the SK look more like a high pressure fan at a glance.

The general rule is more sweep, closer gaps that require a more rigid fan blade and a stronger motor for high pressure fans. High flow fans used to just have a simpler fan blade and a high fan speed.

I've got an old 120 mm fan from way back marketed as the highest flow case fan called the Thunder or something. All they did was sell a fan that runs up to 7000 RPM!!

Maybe Gamer Nexus will start to post a series of fan test as they invested in an expensive fan testing rig.

I think I'll take the risk and get the M25's, I can get them for the nearly same price (£26 instead of £30 for non-rgb), I get over double the warranty, they look nicer, and on a basic paper level they claim to perform better.

I shan't be bench marking them, but at the end of the day we are discussing case fans, there isn't a miles worth of difference between the two (?).

I'll either get to buying them tonight or tomorrow depending if anyone has closing comments they'd like to add.
 
Heads up I've purchased both the Phanteks M25 120mm D-RGB and Phanteks M25 140mm D-RGB three pack in white and replaced all my case fans. The case looks awesome. I may or may not do a followup post showing new temps - probably no better - but hey. Cost me £53 total. I also took the opportunity to fit my IO shield (something has to go wrong on your first build! I also regret my choice of RAM and motherboard chipset, at least AM4 is dead).
