9800X3D + 5080

[sh0_]

There's surprisingly little information about the PSUs on offer, only the 850w RMX specifies that it's ATX 3.1, the other options don't specify at all.
Am I assuming the 1000w RMX I've chosen is the new 2024 ATX3.1 model with 12 2x6 slot? I don't really want the older 12VHPWR from 2021.

Also, anyone have any feedback on the PCS coolers? How do they compare with other brands?

Hiya, please could you read through the above and provide the information requested, there are a couple of changes most of us would recommend that will be guided by the information requested.

The 1000W PSU currently offered is the older ATX 2.4 model, the 750W, 850W and 1200W options are the newer ATX3.1 models that we would recommend for a new build. We would not recommend the PCS coolers; with this sort of budget opting for a reliable AIO from Corsair is sensible as they have a proven track record.

I've edited the post with the info requested. Thanks for the PSU info that's helpful.

I don't really want the corsair ones either for the cooler as they're overpriced for their performance, shame there is so little options in this category. Usually I'd build the pc myself but since GPUs are so hard to get right now the price is almost the same here as it would be collecting the parts and building myself. Maybe ~£100 or so difference unless you can find a GPU for its actual MSRP.

I've edited the build slightly, too.

3x storage = 1TB for OS, 2TB for games, 4TB for storage
I'm hoping I can request where I want the M2s to be configured, I've gone for the Hero as I want to eliminate lane sharing with the GPU and the Hero lets you use the M2_1 (OS) and M2_4 and M2_5 slots. M2_2 and M2_3 are the lane sharing slots and I'd like to leave them empty.

RAM I've gone for the cheapest option as I will be buying my own 6000mhz CL30 and slotting that in instead.

Last point is I intend to have the rad mounted to the front (with the 3 pre-intstalled fans) to minimise temps on both gpu and cpu

That would increase temps, not decrease as all the hot air would circulate in through the build

I've been doing some research on this today and it sounds like it'd be the opposite? With an open multi fan gpu it should actually lower temps;

Physics 101: hot air weighs less than cold air when volume is equivalent since its density is lower; hence, a radiator should be placed on top of the case whenever possible; try to avoid front/bottom, tube-up configurations.

The radiator radiates the hat from the cpu. If you have the radiator behind the intake fans of the case, the hot air from the cpu is being drawn into the case and mixing with the GPU air.

Its impossible to reduce temps with that config

Even Corsair note that mounting it in the top position is the best:

"Mounting the radiator at the top is the best option for sure and most mid and full-tower cases are designed with this in mind"

Just because you can mount your All-in-One anywhere it will fit, doesn't mean you should. Here's how to orient your AIO correctly.

Bear in mind that Ryzen chips are extremely efficient and, unless you are running them full tilt all the time, are unlikely to have any thermal issues. So it's better to mount for optimum GPU cooling

Just so I'm understanding this correctly...

You intend to put the AIO rad/fans behind the original case fans, which will pull in air to blow through the radiator, and the cooler fans to suck the hot air from the radiator into the fan case, GPU and CPU, with nothing blowing the hot air out of the case?

Not true, even here in the GN video they say specifically that front mounted will be cooler at idle and at load vs top mounted exhaust. Only top mounted INTAKE would bring them back to about even. The previous video I showed proves this by actually testing it.

All in all, front mounted (tubes bottom) is better for all round temps.

It will have an exhaust fan at the back, of course, but otherwise yes

 

[Ekans2011]

So, five fans for intake and one for exhaust?
Even if you adjust the intake fans to the lowest speed, I believe you will still have too much air and nearly none will be extracted.

You'd want to maintain a slightly positive pressure inside the case to ensure a constant supply of fresh air as the hot air is properly evacuated.

btw, the air that will cool your CPU will become hot, so it must be expelled from the case rather than circulated inside it... that way, you'll have the opposite effect: lower CPU temperatures (useless because the 9800X3D doesn't require much cooling) and higher GPU temperatures because the air circulating will be hot, not cold.

Huh, that's possible. I'm not entirely sure how much the big radiator would affect the CFM tho. It wouldn't exactly be 5 fans worth of power as theyd all be pretty much strapped to the rad.

That's how the Berserker was originally set up when I got it, as due to RGB ram, there wasn't room to mount the rear at the top, it's now got the rad on the front with air being blown through it, 2 exhaust fans on the roof, and another one in the rear

The case fans are airflow fans, not static pressure, so most of their air won’t made it through the radiator, it will simply cool the front side fins of the rad

The radiator fans on the inner side of the radiator will be static pressure fans, so they’ll draw the intake effectively through the fins.

Just one single exhaust IMHO is not sufficient if you’re running anything over a basic office pc.

Its up to you, but it’s certainly not an optimal configuration.

If there was no space, that's another story, and, correct me if I'm wrong, you have a good balance of intake and exhaust fans, right?

If the case allows it, I'd personally follow the natural flow of air and mount the radiator on the top as exhaust.

Correct on all counts, if it wasn't for the ram the cooler would be on the top, if you do a search for fettling, and my user name, you'll be able to see what I did
