High-end PC for silent gaming / streaming : Coffee Lake or Skylake-X?
Hello dear steam mates,

I want to build myself a completely new high-end rig, that is capable to easily & smoothly do streaming and gaming (2560x1440 @ 60Hz) while staying as silent as possible. GPU is going to be a RTX 2080. Only thing I'm totally undecided is wether to go with an i9-9900K @ 4.6 - 4.8GHz all cores or an i9-9920X @ 4.6 - 4.8GHz all cores.

I know that Skylake-X benefits from better overclock results and has quad channel support, but: is it worth it or will the coffee lake CPU be sufficient enough to do the job?

ok, so let's assume that a single Skylake-X system (e.g. i9-7920X) is not that practical for a gaming and streaming pc. Although I've just watched a video of der8auer on youtube, using excatly that cpu and (!) overclocking 6 cores to 4.7GHz which he assigns to games and the other 6 cores are set to 4.4GHz for other applications. (He recommends highly using a monoblock if running X299 and overclocking).

I've seen now a few streamers who are using a dual system in a big tower, e.g.: Corsair Obsidian 1000D with system 1 for strictly gaming and system 2 for strictly streaming. Would that be a better solution? To go for 2 systems in one case, like: 1) i7-8700K @ 4.8GHz all cores + RTX 2080 for gaming and 2) i5-8600K @ 4.2GHz all cores + Elgato Game Capture 4K60 Pro and no GPU for streaming?

What do you think of that? Better solution then one single system running both?

that sounds like a rather completely overkill setup

the thing is, that you can OC HEDT platforms to high clocks aswell. Dependign on Silicion Lottery you can even OC the 7980XE on all 18 cores to 5.0GHz. AT that point it performs as any other modern CPU like the 9900K @5.0GHz.

However the 9900K can do it with less then half the heat in TDP.

The only games you would see an advantage, are the games that can max out more then 8 cores which no game can.

A Monoblock is nothign else then a normal waterblock that cools CPU and VRM together instead of a normal CPU Water Block and an extra waterblock for VRM.

Streaming isnt as CPU intensive as many believe. You can do it fine even on a Ryzen CPU. No need to go for a HEDT. The 9900K will be more then enough for it aswell.

If you want to sue a cpture card you actually dont need an extra PC if is an internal capture card. It already removes nearly all load from the CPU.


As logn as you dont have a lot of money to burn or doing professional work, stay away from HEDT. They give you no advantage. Their was a time when 7700K price where going sky high that a 7740X (7700K with slightly higher clocks on LGA-2066 with same limitations as the 7700K) + X299 Motherboard was cheaper but now you really have no advantage of them in games.

Go for the 9900k, it will easily cover your needs, or, ideally wait until June to see what ryzen 2 brings to the table.

This is from the view point of someone with both a heavily ocd delided 7900X and a stock 9900k, the new chip beats the old in just about every task and really isn't that hot, mine sits at 5GHz all day silent using a corsair h150i.

@ Monk : you're right, I'll be definitely waiting for the release of new ryzen generation and even more important, for a few independent test. Though I really have to admit I'm a bit of Intel fan boy. But a change to AMD is not out of consideration. As far as I know, Intel will introduce their next gen cpus (I believe "Ice Lake") this winter, so could be also waiting for those.

But I don't want to spend more than a year waiting for "the right" setup / system.
No offense, but it's hard for me to imagine, that a 8c cpu /w HT can easily handle high-end gaming (let's say at least 1080p / 60fps on ultra) and streaming. My problem with the i9-9900K is that it's soldered and I would need to use a Direct Die Frame from der8auer to get the best cooling solution for this cpu (aside from LN2, which I will not do!). Mainboard I would use for the cpu is Asus ROG Formula X (built in VRM watercooling section from EK).

Best regards to all ya!

I think you overestimate the need for cooling and cores. My i7-7820X is by default a 140W TDP CPU and still runs in stock settigns only at 27C idle and sub 40 under normal load.
The 9900K is a "mere" 95W TDP CPU. Means it has only 2/3 of the heatoutput. It will run nice and cold in gaming.
Even if it is sodlered you dont need a DirectDieFrame for cooling. Espacially if it is nto sodlered which means that the IHS is still in place, you simply cant. For using DDF-Cooling you need to delidd first anyways and then for consumers it is easier to simply apply Liquid Metal and re-glue the IHS back into place. The difference is for normal users unimportant.
YOu cant play with LN2 - you might want to check how ti actually works. Its a temporary thing as you need a guy alone to constantly poor LN2 onto the CPU and to monitor temepratures closely and even re-heat it with a torch when you dropped the temeprature to high. Last but not least you going to kill your PC at some point simply because of all then condensing water.
You only use LN2 with a team when trying to set records on overclocking simply as it cant be done alone.


For CPU's, more cores dont give any additional performance. 95% of all games as matter of fact dont even profit from more then 4 cores. No game actually needs 8 cores. As matter fo fact, even with an old i7-4790K you can do high end 4K gaming just fine. Games are more depending on the GPU anyways.


Last but not least, no reason to go for a Water Cooled VRM Motherboard. First you dont even need to water cool espacially if you have no idea about ahrdware and what to actually do. And if you do a Monoblock would be a better solution.

In your case I would simply get a Lian Li PC-O11 Dynamic Case, slap in either a Corsair H150i or a NZXT Kraken X72 and put 6x Corsair ML120 fans (and in case of a NZXT Kraken X72 replace those fans with 3 more ML120) in. Let them run on lowest RPM and enjoy a dead silent PC with superp performance for years (need to upgrade your GPU over time).


PS: Direct frame Cooling is by far not the 2nd best cooling solution, there is also Dry Ice, Cacade, Dive in Cooling with 3M Novec... alot of high performance coolign of which some are not requiring constant monitoring like 3M Novec

Well, for one, the maximus boards this gen aren't as good as they have been previously, if you want the best you'll want an aorus extreme or msi Meg godlike (I'm still considering swapping my maximus code for one of them, I went with the code as I had planned to fit a monoblock for looks, then no ones releasing one for it lol).

The consumer chips don't really pull enough power to need to watercool their vrm.

For gaming / streaming my 9900k spanks my 7900x 10 core, its more than upto the job.

As for being a fan of one or the other, don't be.

Go for what's best for the job regardless who makes it.

I tels next chips will unlikely be any real improvement over the current chips, seeing as they even told their shareholders they won't be getting to 10nm this year, you don't tell share holders you can't make a breakthrough just for a laugh after all.

Edit.
My 9900k with an aio being all but silent keeps my chip at around 60-70c give or take while gaming, there is no benefit to it being colder, unlike the gpu.

I'm only watercooling this rig as it'll look cool in my lounge lol.

My 7900x with sli 1080ti's on the other hand needed to be delided and water-cooled (vrm to) due to how hot the thing runs as it uses WAY more power, and, in games, is slower.

I already have a complete, new, boxed Asus ROG Formula X (Z370, not the newer XI with Z390).
Is this generation really not that good? I've seen a few tests and reviews to that board and everybody said that it is really a high-end enthusiast level board. I had the opportunity to get it really cheap that's why I took it, but I could also sell it again (it's completely new,unused).

And you're right, I should not go for one or another but for what get's the job done in the best way for me, that's why I said that AMD with their new Ryzen to come are not out of consideration (there are still a lot of people / gamers / streamers who claim that Intel have always been and will always be better...dunno what to say or think about that).

@tacoshy: I already have an Lian Li O11-D in black :steamhappy: (love that case!!!). I never had watercooled rig before (neither custom nor AiO). There is one important thing I have to confess here: I'm a radical and huge silent operating system freak! When it comes to quiet and silent PC gaming, I'm amongst the radical in the house of the radicals! :steammocking:

That's mainly why I want a custom watercooled loop for my new system. Everybody is saying (also Roman "der8auer") that if you're aiming for a system as silent as possible while staying as cool as possible (also while gaming!) there's nothing that can surpass a custom watercooling.

My current system (i5-7600K @ 4.2GHz delidded with Dark Rock 4 + EVGA GTX 1060 6GB SSC) is DEAD silent (even while playing games for hours. Temps will not go higher then 38°C, idle temps are 27° - 29°. I think I could even get better temps if I figure out how to undervolt.) I'd like to keep it that way, both in terms of temps and "noise" level.
Building a custom watercooled rig (without hardtubes) is very easy these days, there are a ton of tutorials / guides on youtube and I'm very confident I can build one in my Lian Li O11-D.

What do you guys think of the Gigabyte Z390 Aorus Xtreme Waterforce? (costs a hell lot of money though!)

tacoshy 2019 年 4 月 19 日 下午 2:38 
you are aware that the i5-7600K is a 91W TDP CPu and the 9900K is a 95W TDP CPU. the 4W Difference does not increase the temperatures significantly. The difference is maybe 1-2C
And I dont think a water cooled motherboard going to be worth it. In the end for a normal person a motherboard is just a motherboard.

The onyl reason why I constantly buy 700€+ Motherboards are asthetics, RGB and bragging rights.
