Noctua NH-D15s or NH-U14s

I'm planning to upgrade my PC this year and the CPU I'm currently looking at is the 9900K. I currently have a NH-U14s on a 6700K but, after some research, it seems the 9900K runs a lot hotter than the 6700K. I'm wandering if upgrading the CPU fan is a good idea, or something I can do without.

The NH-U14s will handle the 9900K well, just maybe not if you push it to, say, 5GHz on all cores, unless you get really lucky with the silicon lottery.

Desktop: Intel Core i9-9900K | ASUS Strix Z390-F | G.Skill Trident Z Neo 2x16GB @ 3200MHz CL14 | EVGA GeForce RTX 2070 SUPER XC Ultra | Corsair RM650x | Fractal Design Define R6

Laptop: 2018 Apple MacBook Pro 13"  --  i5-8259U | 8GB LPDDR3 | 512GB NVMe

Peripherals: Leopold FC660C w/ Topre Silent 45g | Logitech MX Master 3 & Razer Basilisk X HyperSpeed | HIFIMAN HE400se & iFi ZEN DAC | Audio-Technica AT2020USB+

Display: Gigabyte G34WQC

The U14S is solid, despite double the core count on the 9900K. I think you'd be satisfied by the cooling performance.

I WILL find your ITX build thread, and I WILL recommend the SIlverstone Sugo SG13B

 

Primary PC:

i7 8086k - EVGA Z370 Classified K - G.Skill Trident Z RGB - WD SN750 - Jedi Order Titan Xp - Hyper 212 Black (with RGB Riing flair) - EVGA G3 650W - dual booting Windows 10 and Linux - Black and green theme, Razer brainwashed me.

Draws 400 watts under max load, for reference.

 

How many watts do I need? ATX 3.0 & PCIe 5.0 spec, PSU misconceptions, protections explained, group reg is bad

Why do you want to go for the 9900K? just wondering since you cannot upgrade a skylake/kabylake mobo to a 9th gen if you're getting a new mobo anyway might as well settle for ryzen 3000

I run a 9900K at 4.6 all cores on an NH-L9i. You should be OK.

 

But yes, note the mobo caveat above.

Ryzen 3000 is amazing, and I'm still considering it. But the 9900k still offers better gaming performance, at least from the benchmarks I've seen. Also, rumour has it intel will be reducing the price of their CPUs so that makes it a little better for me

Still though, r3000 is easier to cool, has better upgrade, and is just better in a lot of ways. The gaming performance gap is MUCH smaller than with ryzen 1000/2000 and for a lot of people it's not noticeable much.

What most people like about AMD is their AM4 socket and backward compatibily, you can use a X370 board to run a 3700X, or a Ryzen 1700X on a X570 board (you see the point), unlike Intel that make a chipset that support X cpu but you can't overclock it, other chipset just don't support higher end CPUs, etc.

 

The NH-14s will do just fine on the 9900K, not optimal cooling performance but will do the job.

Main System: Ryzen 2700, Asus Crosshair VII Hero, EVGA GTX 1080ti SC, 970 EVO Plus NVMe, Crucial Ballistix 3200mhz CL14, CM H500, CM ML240L cpu cooler.

Second System: Ryzen 2400G, Gigabyte B450 DS3H, RX 580 Nitro+, Kingston A400 SSD, Team T-Force 3200mhz CL15

If it ain't overclocked it ain't good...

The NH-U14S should be plenty for cooling. You can always decide to replace it later if you're not satisfied with the results.

Yeah, this is my thinking as well. I plan on using some parts from my current PC, and it seemed unnecessary to upgrade from a U14s to a D15s. But since the 9900k does run hotter, I thought it would be a good idea
