Eh no it's not. Your PSU should be drawing air from outside of the case for a start. The temp inside your case should still be quite low even if your cpu is hot. 70c or so is not really hot either for a cpu.

It's not blowing 70c air around either. That's not how it works. Your temp inside your case is probably only about 5-10c above ambient. Maybe 20c above ambient directly coming from the cooler exhaust.

With the stock fan and 120mm intake, PSU taking air from the roof, the case was hot to touch. With the Noctua that was still the case albeit to a lesser extent, and only the addition of a second fan in push/pull mode dropped the in-case temps low enough that I'm comfortable with the setup.

Not sure where you're getting the idea that an arctic freezer 11lp would be a better option than the noctua. The only setup that I've seen in reviews that matches it is a shuriken 3 with a noctua 25mm thick fan on it, and that's at higher RPM.

That's on the cooler/cooling setup, not the CPU.
Ryzen 3600 uses around 50-80W depending on load & voltage settings.

I have my 3600X under a 360mm AIO at minimum fan speeds and it's a reported 39-45C average, with spikes to 60C.
And that's with PBO so it's hitting up to 1.4V per core at times & low fan speed.

under a 360mm AIO
That's exactly my point. A 7nm CPU at stock, playing a mildly threaded game, shouldn't require a triple-fan liquid cooler to keep temperatures under control in my opinion.

To be clear, I've gone into this knowing that I was going to be dealing with suboptimal thermals in a tiny case. Not pretending otherwise there. But reviews (and I read a LOT of them over the last ... 5 years I've been fantasising about a new build!

) definitely played down both the thermals produced and the performance of the stock fan, which was generally positioned as a given that you'd have to replace the stock intel cooler and thus the intel premium over Ryzen at this performance level was +50 quid +replacement cooler. I think for the 1600 where you were getting a copper based wraith stealth the stock cooler on Ryzen was probably sufficient but the current one certainly isn't.

In an ideal world I'd have a modded sg06 with an SFX PSU at the front and a tower cooler with a roof and rear exhaust fan setup for quietness and thermals but that's well beyond my capabilities.

Thanks to G. for the hint; I am all-core 4.2ghz and dropping voltages to get lower temps. Currently at 68* load at 1.275 volts, compared to 74* at 1.35volts.

You missed 2 important bits:
I've turned the fans WAY down for noise levels (30-40%)
I'm letting PBO do its thing (including spikes to 1.4V+)

Once I get some free time, I'll actually tune it properly.

But one other thing I neglected to mention: Ryzen doesn't thermal throttle until it hits 95C. So hitting 70C shouldn't harm performance or the CPU much.

I just didn't want to buy any new fans/coolers so the 500DX is the only case I found to allow a 360mm front rad + 3x 140mm exhaust fans.
Plus, the be quiet fans are going into the Fractal for resale.

Never heard of them. Any use?

Looks like about a ~14% improvement* over the H mobile parts across the board. I suppose in graphics terms it's not like there's a sudden expanse of extra space for CU's, so it's down to the frequency bump more than anything else.

What are the chances of a price drop for Zen 2's as we get nearer/or into the release window for Zen 3?

I'm half tempted to go from my 7700k to a 3700x late into the Zen 2 lifecycle, and consider a Zen 3 chip further down the road...

Given the COVID situation and the fact they're already somewhat discounted, I wouldn't be hopeful.

7700 has plenty of life in it yet. I'm not sure i would do that.

They'd have to take even a slight hit at some stage when Zen 3 drops and becomes plentiful no?

You reckon? It's a solid chip, but I figured now with 8-core consoles coming out that next-gen titles will push the 7700k beyond it's 4/8 limits?

They may do at that stage but that could be March next year. I also think that AMD will jack up the price of Zen 2 3 based products given their popularity and point to their older parts as the 'value' proposition.

wotzgoingon · 29-07-2020 10:58pm

Zen 2 is actually really good. Each iteration of Zen has been a big improvement over the previous so hopefully Zen 3 will continue the same trend which I believe it actually will do.

7700k is on par with a 3300x, so you don't even have to go up the stack as far as a 3700x to get the performance.

finally the B550 itx arrived....

1 month delay at Austria airport

That MSI mATX one arrived from OC like nearly 4 weeks ago lol

K.O.Kiki · 12-08-2020 5:03pm

tl;dw

MSI B550M Bazooka slightly beats MSI B450 Tomahawk.
MSI B550M Pro-VDH & ASRock B550M Pro4 are great despite being budget offerings.
Asus Prime B550M-A is worst board despite being most expensive.
All boards are OK on 3700X and stock 3900X - but avoid Asus Prime B550M-A & Gigabyte B550M-DS3H for 3950X

Aodhan5000 · 12-08-2020 10:12pm

Tbf if someone was buying a 3950X they'd be fairly braindead to put it with an mATX board imho

Serephucus · 13-08-2020 12:47pm

Why? Not all mATX mobos are budget, and lots of people (myself included) like compact cases.

The only reason I haven't gone ITX, is because I'd like room for a 10GbE NIC. mATX is perfect for this, but lots of companies don't bother wit it, so it's very hard to find high-end, watercooling friendly mATX stuff.

Thankfully compact ATX cases are becoming more popular, but the point still stands: mATX != low-end.

Aodhan5000 · 14-08-2020 6:02pm

Fair point, probably would've been more accurate to say budget mATX. I'd just be if the mindset that if you've enough room for an mATX you probably have enough for an ATX board

Serephucus · 15-08-2020 6:06pm

Yes, that's true. Although that said, I'd take the same volume of case and put an mATX board and more rads in it given the choice.

That was more what I was trying to get at above, but with a lot of unnecessary words.

seraphimvc · 17-08-2020 8:41pm

I forgot to post the benchmark, pretty smoooth i have to say, since i am upgrading from the ancient G3258 lol. when on load it goes to 4GHz without me doing any OC, pretty sweet.
