Build Advice Quietest cooler, case, fans, power supply for i9-14900K build

[kartik_subbarao]

I'm looking for suggestions on the quietest components to support a PC with the following constraints. Don't worry about cost, I'm just looking for the best technical info:

• CPU: i9-14900K
• Power: motherboard will be set to enforce stock limits: PL1 = PL2 = 253 W
• GPU: Nvidia RTX 4090
• RAM: 192 GB
• M.2 NVMe: PCIe 5.0 support (yes I know this drops the GPU to 8 lanes)
• Maintenance: zero/minimal (don't want to open the case on any regular basis)
• Here is a template: https://pcpartpicker.com/list/JXcn6D

Specifically, I'm looking for recommendations on the quietest components for:

• CPU cooler -- it needs to be able to cool up to 253W as stated above
• Case and Case Fans
• Power Supply
• RTX 4090 version -- would prefer the founders edition, but if there is a quieter version that doesn't consume more power, I'm open to other options

Thanks in advance for any suggestions you might have!

There are (or used to be) completely passively cooled PCs, but I am not sure if that is possible with modern parts.

That'd be, well, cool , but seems unlikely with the 253W requirement etc.

On your list, you specify two 96gb vengeance kits.
That is a mistake.
Ram must be matched in a single kit for proper operation.
If you need 192gb here is a vengeance kit that will work

Faster kits at 192gb don't seem to be available.
No matter, ram speed does not mean all that much to Intel.

Whatever your cpu cooler, expect to see 100c. on some cores under load.
The 14900K is designed to operate that way.

Having just upgraded to a 14900K and using a noctua NH-D15s cooler, I ran a test.
I used the simple cpu-Z stress test. First of all, the cooler was quiet. The max fan runs at 1500 rpm which is quiet. Two of the P cores reached 5.985
I used xmp(ddr4) ram at 4000 speed.
Unless you are into competitive overclocking, you really do not need more.
I used a tube of NH-1 paste that came with the cooler.

The case has two front noctua 140mm intakes running at 1000 rpm.
I suppose with a hot graphics card you might want more.

When I opened up the case to change out the cpu, I was aghast at how much dust the cooler had accumulated.
Doing it again, I would use a case with a washable and easily removable front air filter.

On the psu, a 950w platinum cooler like the Seasonic prime will likely be quiet since the fans are not likely to run at all.
Corsair rm1 would be in that category also.

On cases, there is personal preference.
Looks count.
If the case has at least two 140mm front intakes you will be cool enough and quiet.3 140mm is ok and a single 200mm intake would be the equivalent.

Thanks @geofelt for your detailed comments, these are very helpful! Always good to hear people's practical experience. Some thoughts:

• Regarding a completely matched 192GB RAM kit, [ EDIT: this topic is more involved than I thought, thanks for the heads-up ]
• Good to hear the datapoints on the NH-D15, air cooling sounds appealing due to its simplicity
• Regarding the case, I'm debating between more open circulation vs more soundproofing to achieve a low overall noise level. My current i7-7700K and GTX 1080 system has a Fractal Define R5 case and bequiet Silent Wings fans, which has worked very well. Would be nice if I could use a similar setup here. But I recognize that the 14900K and RTX 4090 can use some more air circulation

Appreciate you sharing your experience and suggestions, will check them out.

So what did you choose

So what did you choose

I'm leaning towards the Dark Base Pro 901, NH-D15, and ROG Thor P2 1200. Have been waiting for the Black Friday timeframe, also to see if anything new might be released.
