Air Cooling a 5800X3D in a Meshify C

[Westwood]

Using a CoolerMaster 212 and a bunch of Noctua NF-F12 fans. Curious about what the configuration should be. Right now the CPU tops out at about 84º while gaming. I'm missing a second fan on the top, and a second fan on the 212. So with those added, thinking that should have an affect.

or

or something else? Top fans being the question. Not sure if I should be exhausting them upwards or downwards. I'm wondering if the cool air drawn in from the front will be carried out from the top before it reaches the CPU so inward would be better?

Or perhaps something different entirely?

Thanks.

Personally, I would do option 2 but not much is going to help that 212 out. The 5800x3D is notoriously hot, maybe a dual stack cooler like the peerless assassin you can get for $40 would help out more than adding fans to the case.

Ok, I may try that then. I bought a few more fans because two in there are the stock ones, the CPU only has one now, and I have an open spot on top.

yup, get yourself a pa/ps120 then do the top one

There's five options. But, two not counting RGB which I cannot stand RGB.

Which one am I looking at then? I'm thinking the seven pipe one, but not sure if that is going to interfere with the RAM.

damn. was all stoked to get the new fans in tonight, but I'll order the Peerless Assassin.

 

[Westwood]

Ordered the Seven Pipe version and a bunch of CPU wipes. I'll stick with what I have for a few days and swap everything over.

There's absolutely no airflow in option 2. It's four 120 mm fans trying to force air into a small case that has only a single 120 mm exhaust (+ whatever the GPU is able to push out through its mounting bracket).

I'd definitely go with option 1, also adding a third 120 mm fan to the front. A 3 in/3 out setup should cool the system much more effectively. If 3x 120 mm fans in the front doesn't work out for whatever reason (e.g., the PSU shroud or HDDs interfere), then maybe go with 2x 140 mm units.

Well, if you have a fan going +8000rpm in the back, option 2 might work, but it'll be loud and have hot spots.

 

[pendragon1]

its a meshify, it will all just flow out the back anyways...

I'm going with option one. I just wasn't sure if the air pulled in the front would get immediately sucked out from the top fans before it ever reached the CPU.

I can only do two fans in the front. The bottom portion is filled with two HDD's; not SSD's. Blocks the fan from being able to be installed. Not sure which fans I have in there currently. They take up the entire space allotted in the front. I don't think a bigger fan would fit.

That Peerless Assassin comes in this weekend. Along with forty CPU cleaning wipes. I'll get that all sorted then and return with results.

OP I would do #1 with one of the PA heatsinks. If you can fit 140's, look into that. Otherwise you can add 120's into the gaps.

Personally, I have a 212 turbo super duper black led mega balls edition (basically a 212+ push/pull in black with led) on my 5700x. IF I upgrade to 7950x, was wondering if enough... I have 2 x 140 front intake, 2 x 140 top exhaust, and 1 x 120 rear exhaust in a giant monolith Antec P100. I think I have the 212 pointing UP into the top exhaust, but I have read conflicting info on orientation. It hasn't been a problem so I haven't moved it

Looking at Peerless Assassin PA120 SE is $36 on Amz. Don't care about color or RGB. The thing is so massive though I would probably not be able to point up to top exhaust, and have to point directly into rear 120 exhaust. Prob better for linear airflow anyway.

its big but not that big, not d15 big. you cant mount it "vertically" on am4/5 anyways. it is.

The Meshify C product page states that the front will accept 2x 140 mm fans.

Maybe that's what I have then.

 

[freeagentt]

I am using a Meshify C right now with a 5600X/PA120SE combo and I have the top of the case sealed off, no exhaust fans, 2x140s and a 120 in the face of the case. Works great.

 

[xDiVolatilX]

you did good op, i would do the same thing. 7 heatpipe version with option 1.

Got all the parts on the table right now. Shutting down to put it all in right now. See what happens. be back in a bit.

 

[freeagentt]

You should try and see what works best for you and your fans. I tried all kinds of different configs.

 

[Westwood]

okie doke. all in. cleaned up the wiring.

I crammed another fan in the front. About 1/4 of it is in front of the HDD.

I also mixed up on the CPU fan. I had it,

Fan1 | Heat Sink | Gap | Heat Sink | Fan2

Fan1 was rubbing against the heat sink. So I stuck it in the middle. Works good now.

Sounds good though. Not crazy loud. The real rest will be in a full raid I think. It was 85º at its highest point before. Feels good though.

While it sounds logical, thats not really how case airflow works. You want to force air in, as much as possible for this type of case with a ton of mesh area around the back. This prevents the GPU and CPU coolers from pulling hot air back in from the mesh areas, which they will do readily (even the itty bitty intel and AMD fans can get air back in from outside the case). Having front intake and top exhaust in equal amounts is one of the worst setups because most of the cool air in the front then leaves through the top without ever getting to the stuff it was meant to cool. You wind up with a stagnant area above the GPU where hot air just goes in a vortex and doesn't leave the case at all.

The actual ideal setup would be 3 front intake, 1 top rear exhaust, and 1 rear exhaust. This has been tested thoroughly with many airflow type cases rigged up with temp probes and smoke machines to see what exactly happens. If he was using an AIO, we would actually want the front case air to go directly up, in that situation 3 front 3 top would be ideal.

 

[freeagentt]

The ideal setup really depends on your fans. I have run that case full 120x38s in every orrifice. I’ve run it full of iPPC 3Ks, and with that case, there is such a thing as too much. 4 in 2 out works good. I would resist using both tops as exhaust. Mainly because a good chunk from the front fan will just get pulled out of the case before making it to a cooler, effectively becoming useless.

 

[Krenum]

Get a NH-D15 and go with the First picture Option.

Yes, it will fit. I ran a NH-D15 in my Meshify C for years.

 

[xDiVolatilX]

The first picture would be better if there was an additional bottom floor intake. Is the mounting holes there? My other case didn't have one so I went in with a Dremel and fashioned a 140 with mesh dust cover. Works like a charm the air cooled 3070 gets a refreshing blast of fresh air from the bottom directly into the intake fans. Entertain the idea if you want more cooler air flow, case modding could be fun.

 

[xDiVolatilX]

Also in the second picture you could try the first top fan near the front to intake from the front top and the second rear top fan to exhaust. That would give the CPU air cooler cold air from it's front intake and then have the rear and rear top exhaust fans exhaust it out. Just have the intake fans speed and air pressure higher than the exhausts.

Peerless assassin 120 se working well on a 7700x build I did, bet it'd do well on the 5800x3d.

It does do well on X3D. With FC140 I can run it semi passively with the stock Torrent Compact fan configuration. I honestly wouldn't buy D15 in 2023.

 

[Westwood]

Had the day off. Gamed for, well, just about all of it. ¬.¬

Maxed out at 82. I think I'll live with that.

 

[Westwood]

So I just discovered something stupid.

I'm at 75º at idle. Seems high.

Netgear Genie. Something that has always been running. I figured I needed it for the wi-fi to work. Check my CPU usage, and Netgear Genie is at 25%. I exit out of it, within ten seconds I'm at 48º.

Hah, its 45º now. Even my fans are on low now. wow, what a difference that did.

edit: I click the genie thing back on, instantly at 78º. what in the hell...
edit2: shut Rainmeter down. 35º.

 

[Mega6]

I prefer letting physics work for me and in low and out high. Unfortunately thats not possible in all cases. Front to back or back to front should work fine.

yea, I was about to flip the top fans to suck in. but now that I have the stupid netgear genie resolved, I'm curious what its going to run in game now. I can't believe the temp dropped 40º in, I'm dead serious here, a second.

 

[Mega6]

LOL Genie - if there is one task you should have in your startup, it's taskmgr. Keep an eye on that stuff - always. Good lesson there for everyone.

I didn't even think anything of it. I figured that was for the wi-fi. No idea. I feel so stupid. That and I'm probably going to drop Rainmeter. Been using that for 10+ years. I have it setup nicely. I'd check it often. But I guess its just as easy to check the weather online. And, really, there isn't much on the PC that I need to keep any eye on. CPU temps is about all, and I have that in my little taskbar window.

Reducing the refresh rate of rainmeter doesn't help? I don't guess they have an updated version that's better optimized...

I think I have weather on a five minute update. I could change it, see what happens. meh. I have it updated though. It was using between 8 and 15% cpu though.

 

[Mega6]

That weather app crap is usually chocked full of spyware (like most of the mini-startup-progs). Just use a web page with noscript, privacy badger, ghostery, ublock origin, add-block plus plugins. Firefox is typically the safest main stream browser but there are specialized ones as well.

Its not an app; I don't think? Came from DeviantArt. Run in Rainmeter.

Oh it's a skin api. I see.

 

[Westwood]

Alrighty. Current temp, 35. Firing up the game and see what it gets to be.

 

[Westwood]

So there's an improvement.

Good to go I'd say. Neato.
