CPU Clock Rate

3.6 GHz

CPU Temperature While Idle

30.0° C

CPU Temperature Under Load

85.0° C

GPU Core Clock Rate

1.632 GHz

GPU Effective Memory Clock Rate

8 GHz

GPU Temperature While Idle

33.0° C

70.0° C


Finally decided to upgrade my i5-4670k after 5 years since it was bottle-necking me hard at 144Hz. Decided on the i9 since I wanted strong single core performance but also wanted 8 cores/16 threads. Kept the GTX 1070 that I already had, may upgrade soon.

Part Reviews


Best gaming performance money can buy.

CPU Cooler

Keeps my i9-9900k at 5GHz cool under load.


VRMs can run a bit hot but besides that great board, with a pleasant to use BIOS and really nice RGB. Note that the RGB over the IO shield is pretty dim.


Best looking RGB RAM on the market

Video Card

Best GTX 1070 in production. Performance and temperatures are great, and the RGB is amazing.


Amazing case at a very competitive price point, I love the integrated RGB.

Power Supply

Clean quiet power what's not to love


Great G-Sync monitor, note that setting the monitor to 1ms may cause ghosting.


Great 4k IPS monitor, make sure you get the software from Dell's website that lets you control the brightness from your computer.


The best keyboard I have ever used.


Hands down the best mouse available.

Nice! Over clocked or just running that hot under load stock?

I'm using ASUS AI OC, currently its running at 4.9GHz, I think it couldn't get it stable at 5. Might try a manual OC if it doesn't figure it out soon, it seems to adjust itself.

a6600 2 points 5 months ago

Oh okay! I tried the AI thing and it added way too much voltage and temps were pretty high under load, I am running a 9700K though. Switched to manual overclocking and adjusted voltage until I found a stable clock and temps dropped significantly! Regardless congrats on your build, looks great!

Thanks! Yeah I'll give manual OC a shot, glad to hear you got your 9700k stable at good temps.

1070 with 9900k? seems overkill for me

Robotdude submitter 2 Builds 2 points 5 months ago

I'm reusing the 1070 from my last build, and I do a lot of productivity tasks that benefit from the high clock speed and core count.

How is the airflow with the case? I like it but want to make sure it gets good airflow.

Robotdude submitter 2 Builds 2 points 4 months ago

Pretty good, I get 62 deg c temps under a decent load (for both GPU and CPU) with all fans maxed. Certainly a lot better than the P300 and P400 due to the larger side vents.

Can the x62 handle the 9900k at 5ghz or higher

Robotdude submitter 2 Builds 1 point 3 months ago

It's fine at 5GHz, not sure about higher.

Thx for helping I appreciate it

Nice build!

Just curious, do you get full NVME speeds from each of your two M.2 drives?

Did you have to do anything to get them both set up to run at NVME speeds?

I’m looking at this motherboard and CPU and am a bit confused about the speeds at which two M.2 NVME drives will run and specifically whether you can get both to run over the chipset’s PCIe lanes for NVME speeds or whether one of them will run only at SATA speeds.

Robotdude submitter 2 Builds 1 point 4 months ago


Yes you can get both of them to run from the chipset at NVME speeds. You will get up to PCIE 3.0 x4 speeds max combined from both SSDs. They both run at NVME speeds, but if you try and use them at the same time there will be a bottleneck. If you want them to run unrestricted you will need something like the Asus Hyper M.2 card.

Hope this helps, please let me know if anything is not clear.

DeepPuffin 1 point 4 months ago

Thank you so much for the response!

What exactly does it mean to use them both at the same time? For example, if I’m running Windows on one of the drives and run a game (or more intensive application for storage) on the other, could there be a bottleneck then?

Would it make sense for me to go with one 1TB NVME drive instead of 2 500GB NVME drives to avoid bottlenecks / restrictions? Or am I just overthinking things? :) Why did you opt for the two separate drives?

Btw, do you have any thoughts generally about running the NVMEs through the chipset lanes instead of directly to the CPU? I’m guessing the difference is not discernible, but I’d be curious if you know anything about it / have any thoughts. I’m not even sure whether it’s really possible to run an NVME drive directly to the CPU lanes in a build with this CPU where there’s going to be an x16 PCIe GPU (without restricting the GPU)...

Thank you again, I really appreciate the help.

Robotdude submitter 2 Builds 2 points 4 months ago

Using them both at the same time means requesting a total read/write of over the PCIE limitation. While technically there could be a bottleneck when you use them like you said, its very unlikely that you will be reading or writing enough information to hit that bottleneck.

I would recommend getting the 1TB drive which leaves a space for you to put in another one later. I used 2 just to get the fastest speed possible, but realistically its only a little bit faster than a single drive.

You are correct you cannot run anything else directly to the CPU with an x16 GPU unless you dropped the GPU down to x8. While x8 mode can use some gpus to their max potential, the types you would pair with an i9 (2080/ti) would prefer the full x16.

So helpful. Thank you again.

No problem, glad I could help

Awesome build! Keeping an eye on this case for a while aswell, but how much space do you have left between your radiator and i/o connectors, cause i know 280rads can fit, but the one i’m looking for is 7mm longer then the nzxt x62 rad. And how much space is there between your gpu and front fans/rad? Just wondering :)

Robotdude submitter 2 Builds 1 point 3 months ago

There is plenty of space between the GPU and front fans as shown in the third pic. Not sure of the exact measurement sadly.

The rad and io connectors are a very tight fit, the rad is mounted at a slight angle to make it fit and I really doubt a longer rad will fit at all. They really should have made the case a bit taller, I had a tough time fitting the fans above the mobo vrms.

Thanks for the fast reply :)

Ahriona 1 point 2 months ago

Are you able to use Aura Sync with the RGB on the case with the addressable header on the motherboard?

Robotdude submitter 2 Builds 1 point 2 months ago

Yes, it works great. Note that the front LEDs only light up if you connect the case's SATA power connector, but the side LEDs will work regardless.

Ahriona 1 point 2 months ago

Awesome! I wasn't sure if it would still sync up with the addressable header or not. Thank you :)
