Cooling issues

[JWReplogle]

Specs

R7 5800X - no OC

RX 6600 XT - no OC

Corsiar 140 MM single CPU AIO Cooler - mount front, air sucked in through radiator 

1 front 120 mm fan - air in

1 back 120 mm fan - air out

1 top 120 mm fan - air out

 

issues, case is too small to mount CPU cooler in top or back to blow hot air out.

I'm actually blowing hot air in and back/top fan are blowing out.

 

Would it be feasible to reverse direct of all fans and blow air out of front of computer?

[MonkeyBomb]

You could reverse the fans, but no real need to.

 

You have a 140mm with rad as intake on the front and another 120mm fan as intake on the front as well?

 

The 5800x is a pretty hot cpu, a single 140mm AIO seems like it'd be a little small.

[Kid.Lazer]

It probably won't perform the greatest, since you'll be fighting natural convective air currents that want to rise from the components. But if you're already having thermal issues, it certainly doesn't hurt to try. Just make sure you keep track of your before/after temps to see what, if any, changes occurred.

 

And as @Cypher64 mentioned, a single 140mm rad is very inadequate. A good tower cooler would get you further.

Either undervolt your CPU, or buy a better cooler.
If the rad is already intake, putting it as exhaust might be worse in your situation.
Intake = The rad uses fresh air to try and cool down the liquid inside it. Everybody else inside gets the leftover air.
Exhaust = The rad uses air that has mixed with what expelled by everybody else.

IIRC i saw somewhere that 5800x is hotter than a 5900x

Btw, what's your ambient temperature

Lol, that "due to" was omitted in the edit.
Can't really remember.
Something about core speed retaining i think.

Only having one CCX with all cores and threads enabled. It's much more dense of a CPU. 2nd spoiler in the quote below.

In that case, here's the X570 version. Same price as the MSI B550, a little bit more features in the chipset. And pretty much same color scheme. Tier A VRMs, should still hold up plenty fine with a 5800x. As far as how their PBO works and all that, I'm not sure.

As far as how overclocking would work on AMD, here's a couple of quick videos on how PBO works, and a really good undervolt guide. It is very possible to undervolt and get an overclock in return.

Since I said I would work on explaining why the 5800x is so hot once I was at my computer.

It has to do with how AMD is handling changes to their charged coupled devices(CCD). Each CPU core complex (CCX) allows for up to 8 cores and 16 threads. The 5600x will have 2 cores and 4 threads of it's CCX disabled. The CCX isn't being pushed as hard by default. The 5900X and 5950X will each have 2 sets of CCX, with the 5900X having 2c/4t disabled in each one. There's two there, but they're not working hard. This is why cooling a 5900x is almost closer to trying to cool a 5600x than a 5800x or 5950x. The 5950x will have 2 CCX with all cores and threads enable. It's a hot son of a gun. However, you are usually not using each CCX as hard due to how core and thread usage is handled. 

Where people get into trouble with the 5800x specifically is that it's "Only" 8 cores and 16 threads. It should be easy to cool, but the components on the 5800x are working "harder" and producing more heat than they expect.

 

5600x/5800x

5900x/5950x

 

That's at least my $0.02 on what I've gathered reading about Zen 3.

Due to 8 cores on the same CCD vs 2x6 on the 5900x

[mike_seps]

So, may as well go with the 5900X or 5950X. Noted

[JWReplogle]

OK

 

I'm going to purchase a 240 cooler and I will have to mount in front again.

I have room for the 240 setup not the 360.

Is there any reason you want to have an AIO over an air cooler?

Only if you need the cores. 5800x does really well with a slight undervolt and negative PBO offset. First spoiler in the link above. I was able to run a 5800x off a baby L12s with 4.8 all core and no throttle. Less power with PBO can make more speed up to a certain point.

With a 240 you'll probably want to play with some PBO settings and negative offsets. The second video in the first spoiler in my post above is a very good guide. First video in that spoiler explains their boosting system. It will run warmer at idle and low clocks than you're used to. 40C isn't that uncommon for them to idle/light load at. Temps under load are what you're paying attention to. My particular CPU and motherboard were happiest with a -20 offset but YMMV. What case are you using?

With a 240mm they'd be looking at top of the line NH D15s, Scythe Fuma 2 and other dual tower coolers to compete.

Good to know. I probably won't be upgrading any time soon, have the 5600X right now and it's running just fine. Haven't hit any real bottlenecks or slowdowns yet

[JWReplogle]

what about?

and no im not stuck on AIO cooler

 

My last system the MB fried on a friday night and the local store only had a single AIO cooler in stock.

 

 

[JWReplogle]

I also watched the PBO videos 

I reduced mine to -25

Air cooler is less prone to failure. In the event it does fail, it's less likely to go to the full on disaster route.
Unless you go AIO for something like aesthetics or more empty space inside the case, or using a seriously hot CPU, like 12900k or something.
I'd suggest just sticking with air cooler for your build.

A good quality air coolers lasts forever, as long it's not physically abused.
The fan will die at some point (very very very very long), but as long it uses a standard 120mm / 140mm fan, it's easy to replace.

I think you need something more robust.

Deepcool AK620 is a good option, it goes toe-to-toe with the what people subbed as "The King of Air Cooler". Which is Noctua NH-D15
Noctua NH-D15 also a good option, if you want it black color it's NH-D15 Chromax . They are more expensive though, especially the Chromax.

IIRC, AMD said the new AM5 will use the same mounting as AM4, so in the event you upgrade your CPU later down the road with another AMD, you can use it.
Plus usually the respective brand provide (either free or paid) a new mounting kit, if there happens to be a sudden change with the socket.
Like what happened with Intel's LGA1700. Not all coolers gets one, but the top end coolers all gets one.

The heatsink? it will be above your ram stick a bit. Unless your ram stick height is more than 59mm.
The rightmost fan will hang over your stick, you might need to move the rightmost fan above the cooler's heatsink, how much upward depends on the RAM stick height.
If the ram height is under 43mm, you don't need to move the fan upward.

Check your PC case if it has enough CPU Cooler clearance though. AK620 needs atleast 160mm PC case clearance.
