Build Advice Quiet gaming rig advice ?

[Daniel_Daniel]

Quiet gaming rig
OK – I want 2 things that don’t necessarily go together – something to game on, and something quiet. This will be my first build. I really don’t like all the humming and buzzing you get from a normal PC, and I’m prepared to compromise a bit on other specs to keep noise down.
Other than having a big crush on the be quiet! case, I’m open to suggestions on how to do this better.
I have zero interest in custom lighting. I giant black box that is quiet is my ideal.
I’ve got a nice sit-stand desk, so I’ll probably put the PC case under the desk (but raised a little on a small table) for more sound insulation.

Approximate Purchase Date: I want to accumulate parts over the next 3 months, and build the machine during my Christmas break.

Budget Range: AUD $3500 -4000ish
The current list of parts adds up at $4144, which is too rich for my blood, but I’m not sure where to cut back.
My current PC has the ZOTAC GAMING GeForce RTX 3060 Ti Twin Edge OC LHR 8GB GDDR6, and I’d like a step up from that (but quieter). I won't be cannibalising the old PC.

System Usage from Most to Least Important: quiet, gaming, office work and household stuff.

Are you buying a monitor: No

Parts: (e.g.: CPU, mobo, RAM) Include Power Supply Make & Model If Re-using

Note: some of these seem to be mail-order only parts, so I’ll be adding a premium on top of this. I’m not sure what that is.

Case comes with a built in fan speed controller and the cpu cooler runs quiet. btw I'd look at Windows 11 Home instead of Windows 11 Pro if you're looking to cut cost.

For a 4K monitor get a 3080 at least. I see no need for all the drives.

[geofelt]

You are missing the boat with a 9700K.
Newer 12th gen is better in every way.
The i7-9700K has 8 threads which are usually ok for gaming(multiplayer excepted) It has a passmark rating of 14561. That is when all 8 threads are fully utilized. Not a common occurance in gaming.
The single thread rating is 2909 which is more important for games.
By comparison a 12th gen I3-12100 has 8 threads and a similar rating but a stronger single thread rating of 3550. It is also vastly cheaper.
More likely you would look at a I5-12400 12 threads 19538/3531
Still cheaper.

Most any B660 or Z690 motherboard will be fine.

Scythe makes very good coolers.
The ninja5 uses 120mm fans.
For quiet, look at the Noctua nh-D15s with slower/stronger 135mm fans.

The noctua based Asus graphics cards are supposed to be very quiet.
Probably a good choice there.
But, for faster action gaming, perhaps you can manage the 3080 Noctua version.

Seasonic Prime are very good power supplies.
But, I think 1000w is overkill, 850w perhaps.
If you want to save a bit, look at the prime PX 850.
The Prime series are longer. If your case restricts psu length, the focus units are 140mm.
Seasonic warns you not to be alarmed if the fan does not run.
It will only do so under the heaviest of loads which you will not see.

There is no performance value of 4 500gb drives vs a single 2tb ssd.
And no real benefit from the PRO version. endurance is no longer an issue.
Use a 2tb m.2 970EVO plus. You will get the benefit pf pcie speeds.

Under the desk is a good idea from a noise point of view.
The more distant from your ears, the better. If the power button is not convenient, there are cheap power button extenders.

Cases are a personal thing. The case you picked is reasonable.

[Daniel_Daniel]

Thanks All, lots of good advice.

I'll try come up with a revised list of parts, and per @Why_Me I'll need to be more attentive to free delivery options, as I can see how this will quickly add up.

I have zero dogs in the fight so far as AMD vs Intel is concerned for both CPU and GPU - other than I want more grunt than my current RTX 3060 Ti.

I had heard that AMD runs cooler, which I guess means quieter, so if anyone has any advice on AMD alternatives (or indeed, if I'm just way off base), that'd be appreciated.

I don't know a whole lot about AMD builds other than the alternative would be the 5900X + B550 board.

Thanks @Why_Me that's helpful as the AMD costs about twice as much as the i5-12400 recommended by @geofelt, which isn't going to help bring my project under budget!

I had heard that AMD runs cooler, which I guess means quieter, so if anyone has any advice on AMD alternatives (or indeed, if I'm just way off base), that'd be appreciated.

tbh, since AMD switched with zen2 to chiplets, they are much harder to cool down then intel counterparts (same apply to zen3), 80C under full CPU load is what they do even with best coolers, gaming usualy sits around 60C as games have low CPU utilisation
its not like its an issue, as you can run fans at low/vs high speed and it will have minimal impact on CPU temperature, in games GPU will heat probably more than CPU as those can run 80C+ in games which also adds a bit of heat to your CPU intake
you can add 3x140 fans at top to reduce heat abit

Good you are reading the fine print before you buy.
Download the case instruction manual to see how it all fits together.
Read a review of the case.
Here is one:
https://www.tomshardware.com/reviews/be-quiet-silent-base-802-review

1) Motherboards will come with the latest bios available when it was made.

2) Not a big deal. Drive bays are easily removable if need be.
And, with the transition to ssd devices 2.5" devices can fit anywhere.If you need many 3.5" Hard drives for storage, then calculate.

3)All new Noctua coolers will come wit lga1700 mounting.
If you happen to get a very old unit that lacks the adapter, noctua will send you one free.
It takes about a week.

 

[Daniel_Daniel]

Thanks everyone, you've all been awesome!

I'm going to slowly start accumulating parts in anticipation of my leave.

 

[geofelt]

It is usually best to buy all at once.

On occasion, parts will be defective and past their return date when you finally assemble.
There is no rush, parts get better price/performance over time.

You may discover, too late, that your needs have changed.

Perhaps the best part to buy early would be the case of you get a deal on the one you really want.

 

[Daniel_Daniel]

Thanks @geofelt, good tip!

Quiet pc's are easy to accomplish, if that's your primary concern. All they require is overkill cooling.

That's the hard part. On the one hand, some feel a silent based case with noise dampening baffles is the way to go. There's just one major problem with that idea. Lack of airflow, which is the lifeblood of cooling. Airflow starts with fans having good access to air, and a case front with a damper or door does nothing but block noise, doesn't help airflow.

On the other hand, having great airflow means wide open avenues for any noise to escape.

So the answer is cooling. That means a Platinum rated psu. The higher the efficiency of the psu, the less heat is wasted in AC to DC conversion process. So the fan doesn't spin as fast.

Oversized cooling. The better the cooler, whether aio or big air, the better it works. That means the fans don't spin as high as on a lesser cooler to do the same job.

140mm fans will push the same cfm as a 120mm fan, at lower rpm. Less noise.

Use OC versions of gpus but cut power limits back to stock or get a DTW Evga, which is an FTW heatsink on an SC clock. The better and beefier heatsink won't require fan speeds and high associated noise with lowered clocks, but performance will be no worse than standard for the card.

Airflow case. The better the airflow, the cooler components will run vs same performance in a airflow restricted case. Creates less noise.

But be prepared to allow slightly elevated temps in order to chop fan curves. There's realistically no measurable performance difference in a fan running 90% and a fan running at 100% but that last 10% will double the noise output.

If possible, and budget allows, I'd opt for the 3080ti over a 3080. Considerably stronger card, especially at 4k workloads, and fps isn't in the equation. What is is the ability of the card. You'll be pushing the 3080 close to its limits at 4k, that means almost max power hitting the heatsink, rated for that card. For the same performance a 3080Ti will have more headroom, and has a beefier heatsink. Asus ROG has about the best setup on the market for cooling and some of the quietest fans.

Thanks @Karadjgne The case comes with 3 built-in 140mm be quiet! fans, and I think also they've put a bit of work into making sure the case doesn't pick up vibrations, since that seems to amplify any sounds. I'm also going to try and keep it off the desk, since distance will make a big difference.

The 3080 Ti is a little rich for my blood, but you make a good point. I'll leave buying parts as close as possible to my annual leave (probably Christmas), in the hope that prices drop a bit more.

 

[Karadjgne]

Keep an eye on pricing, as often as possible. The gpu especially. Most assume prices will keep lowering as stores make room for the next gen gpus. That's true, to a point, even having 'fire sales' if inventory isn't moving fast enough. But as is often the case, when supply starts to dwindle, demand goes up, and prices follow.

Black Friday/Cyber Monday will probably see the lowest prices, after that they'll climb as stores can charge more for their limited stock.

 

[geofelt]

Since you will be buying closer to Christmas time, here are a few thoughts:

On the power supply,do some research.
I like the Seasonic units but the various prime/focus and sub designations can be confusing.
Here is a decode chart:

If you have ever built your own high-end custom PC you will have no doubt come across and probably u

www.kitguru.net

On efficiency, do not chase titanium efficiency vs. lesser efficiencies.
The price paid will not be recovered in electricity cost savings.
The wattage matters. A psu is most efficient in the middle third of it's range. The main selection criteria is the wattage required for your parts.
Particularly the graphics card. Wattage calculators are deadly accurate IF... you can provide accurate information. But we can't.
Nobody knows what a future graphics card upgrade might bring.
Or, what peak transient demand your graphics card may demand.
I have found it useful to use this chart:
http://www.realhardtechx.com/index_archivos/Page362.htm
For 3080 class cards of today, 850w would be plenty.
Seasonic includes a testing plug for the 24 pin cable.
If the fan runs when power is applied, the unit is functional.
When I have done this, I can't hear the fan on my newly acquired 850w prime unit.
You can do some research here:
https://seasonic.com/prime-gx

In the USA, Seasonic has, in the past, had some very good sales in the fall so look for that.
Power supplies have not changed much over the years,
But it looks like graphics cards of the future may have a single 12 pin pcie power connector.

The release date of Intel's Raptor Lake CPUs and 700 series of Motherboards has been leaked by Enthusiast Citizen. As per the rumours, Intel plans to

appuals.com

In part, this is to counter the upcoming AMD 7000 series processors.
Normally, expect to see about a 15% boost in price/performance from either camp.
I would expect either to need less power for a given performance level and thus will run quieter.
Rocket lake is compatible with current Z690 motherboards after a bios update. There will be an updated Z790 chipset with unclear advantages.
Be prepared to do some research.

New graphics cards are coming. Including some from Intel.
Rumors abound, Fun reading, but the test is from legit reviewers at launch time. Again, expect to see about 15% price/performance boost.
The big talk will be about the top(very expensive) cards which will be launched first.

Approximate Purchase Date: I want to accumulate parts over the next 3 months, and build the machine during my Christmas break.

if you are planning on waiting until the end of the year to get it all together i would not put much stock into the interior(CPU, motherboard, RAM, etc) quite yet.
Intel 13000 series and Nvidia RX 4000 series are on the way so prices and performance options could be very different by then.

case: be quiet! Silent Base 802 ATX Mid Tower Case

nicest case i've seen or worked with for many years.
i've recommended them to a few local friends & customers and they are a breeze to build in and have many awesome modular features which leave many ways to go with your setup; super high airflow, super quiet, mix of both, right or left facing motherboard, one of the best multi-fan & radiator placement options, front I/O USB type C(3.2), etc.

CPU: Intel Core i7-9700K

Motherboard: SI MEG Z390 ACE

definitely ditch the 9th gen.
MUCH better performance on even lower-end 12th or possibly 13th gen series for nearly the same price.

but i would certainly stick with the higher end Z*90 motherboards.
they almost always have better VRM cooling, more headers available, and a lot of the time more room for airflow between components.

CPU cooler: Scythe Ninja 5

the newer Scythe coolers seem to get some good praise and i see it for ~$95-110 right now vs the $209 you have listed.
but i would always stick with either Noctua or be quiet! for air cooling needs.

the Noctua NH-D15 chromax.black goes for near to the same as the Ninja 5, ~$125.
the be quiet! Dark Rock Pro 4 goes for even less, ~$90.

GPU: Asus GeForce RTX 3070

if you're really planning on 2160p gaming i would be going for something quiet a bit stronger than the 3070.

i used the RX 6700 XT, which is very similar to the RTX 3070, for a bit earlier this year and even at 1440p it was very disappointing.

moving up to the RTX 3080 Ti handles my 3840x2160p 120Hz TV very well. with HDR & RT effects enabled in games i can remain rather close to 100-120fps.
on my 3440x1440p 120Hz monitor maintaining 120fps in the most demanding games is fairly easy but the RX 6700 XT stayed closer to 80-90fps even with some lower settings.

Power: SeaSonic PRIME TX-1000 1000 W 80+ Titanium

i'd be looking more at a nicer 850-1000w Gold series.
spending an extra $200 for this type of Platinum rating is not really worth it vs the higher end Gold standards.

if you are set on Titanium series; the be quiet! Dark Rock Pro 4 1200w is only ~$400 vs the $479 you have listed for the Seasonic.

RAM: Corsair Vengeance LPX 16 GB

for this type of setup i'd definitely be going with 2x 16GB vs the 2x 8GB.

and by the end of the year when you'll actually be building this, DDR5 may have even dropped enough in price to finally be worth the upgrade with the right motherboard.

Storage: Samsung 860 Pro 512 GB 2.5" Solid State Drive x 4

i don't really see a point to having 4x smaller drives.

i would alter this to 1x 512GB for OS & applications,
1x 2-4TB for games,
and 1x ?? for backup purposes and other storage.
