you don't need an exhaust fan at all.

put your best fans as intake and put your crappy fans as exhaust.

ez

 

You picked the Fuma 2 not the Mugen 2 that one is ancient and is no longer being sold new

As the fans two in the front one in the top and one in the back is fine bottom fans is not going to help anyway unless you have drives or a rad blocking the whold front which you dont

As for the stock fans they are crap they are 1000 RPM 3 pin fans so they move bugger all air even at full blast and you cant control them in any way

 

The three fans it comes with aren't bad. They are near-silent at full speed, however, I purchased two Silent Wings 3 1,600 RPM fans. I only have one fan at the bottom of the case as I use the hard drive sled/tray - you can easily fit two 140mm fans in the bottom. My setup with this case is:

• Bottom | Silent Wings 3 1,600 RPM | Intake
• Rear | Silent Wings 3 1,600 RPM | Exhaust
• Top | 360mm radiator with three Corsair ML120 (2,400 RPM) fans | Exhaust
• Front | 240mm radiator with two 140mm EVGA 3,500 RPM fans | Intake

I hope that's of some use.

The bottom fans are positioned to bring fresh air straight to the GPU, with at least one having a pretty direct route (large holes in the case shroud).

 

Sorry about that getting the name wrong. So I don’t need more than one top exhaust even though I could literally line it with like 3 since it has room for it. I assume the one top exhaust should go to the very left above the cpu cooler. And I’ve seen some people with 3 front intake

 

You can add two more fans so you got 3x in the front 2x in the top and 1x in the back but its not going to make any major difference
I had 4x fans in my XL case before and when i upgraded i bought 6x fans since they came in packs of 3 and the temps are the same as before the 2x extra fans made no difference

If you have really power hungry parts overclocked to high heaven more fans can make a difference but from what you said you had no plans for extreme OC and your parts dont draw a ton of power

You can add more fans but its just more noise and power draw for no gains

 

Aww, when I heard Mugen with a 12700k my ears perked up. I've also got a Fractal Define C which is pretty similar in size to a Meshify. This is what I did: Started with a Mugen and went to a D15. D15 is maybe good for +100mhz under the TVB+2 limit of 70c for benches, but not too relevant for games. And I always did want a Fuma, but they were never there when I had justification to buy a new cooler.

Also my top fans may be a placebo, but I like to think they aren't since the back of my case is pretty close to the wall. And the side fan is a hack job that just looks passable.

 

Thank those pictures really help. I have one more question. Should be running either the front panel or top panel without any filters for airflow and temps or does it not make it a difference. What are you guys doing?

I've already provided an optimised configuration (ignore the rads) in detail as a Meshify 2 owner, although I'll add some more detail about the filters, fans, and some things I like about the case.

• Filters: They are probably the best filters I've ever seen in a case. Each one (front, bottom, top) is easy to remove and completely toolless.
• Cleaning: Due to the fractals pattern used on the nylon filters with ridges of plastic, they can be fiddly to clean.
• Case access: It's almost entirely toolless, with every panel being easy to pop off.
• Cable Management: There are grommets and included Velcro cable ties. The only negative, is the cheap piece of flimsy plastic that's meant to keep the cables tidy. It's a waste of plastic and I haven't used it.
• Fans: The included fans (Dynamic X2 GP-14 ) which sell for ~£12/$16 each, are not the best in the world, but at 1,000 RPM +/- 10%, and being near-silent 30cm away from my head, they are fine. I suggest you read some reviews from users and trusted reviewers - they have received very positive reviews, especially in noise:airflow.

Fan Layout (no water-cooling)

• Front: 2 * Noctua NF-P14 | Intake
• Top: 2 * Dynamic X2 GP-14 | Exhaust
• Rear: 1 * Noctua NF-P14 | Exhaust
• Bottom: 1 * Dynamic X2 GP-14 | Intake

Out of the six fans in the layout above, three come with the case and you have the others on order (I didn't see how many NF-P14 fans you ordered).

Since you are only going to use a few fans and no radiators, you could save money and space by going with the equally-good Compact version (Meshify 2 Compact). There seems little point in getting a case heavily optimised for airflow and with radiator support for 420mm. To give you an idea of the space available in the case, I'll show you what mine looks like inside, but won't list fan configuration as I've already done that above:

• Top has a 360mm CLC - as you can see, there's still plenty of room there
• Front has a 240mm CLC. Underneath that radiator, there's a plastic panel that is fragile but easy to remove. You can fit another fan there
• Rear has a 140mm fan, bottom has a 140mm fan
• The motherboard is a standard ATX size, so as you can see the case is actually quite large
• The graphics card is an EVGA RTX 3080 Ultra Hybrid (dual slot)
• In the shroud, there's obviously the PSU, but also the bottom fan and a drive cage with 2 HDDs in it and two SATA SSDs vertically mounted to the cable sorting area (it has brackets included)

Anyway, my main point is that my case is quite full, but has a ton of space. Without radiators, it's going to look very empty (even with a large tower cooler).

Sorry for the quality of the photo. And for anyone concerned about the hoses, there's plenty of flex in them - it just doesn't look that way.

 

Air cooling fan setup is very different from water cooling. With air cooling any top exhaust fan not behind front of CPU cooler will draw the cool air coming from front intakes out the top thus allowing heated air off of GPU to move up and into path of air moving into Cpu cooler.

Stock Fractal case fans are Dynamic X2 GP-14 with static pressure rating of only 0.5mm H2O at full speed. That is almost no ability to overcome grill and filter resistance. We want fans with a minimum of about 1.0 mm H2O @ 1000rpm, twice what Dynamic X2 GP-14 is.

To put static pressure rating into perspective, there is 1.836 mm H2O more air pressure on your feet than 5 feet above (about neck level). 1.836 mm H2O is till very little, but way more than stock fans have.

Use your best (highest pressure rated) fans as front intake and block (tape) off all openings in fan mounting panel not covered by these intakes so air they move into case cannot leak around in front of fans to go in circles but must move on thru case and out.

As already said, using both intake and exhaust is generally not better. It's like running push / pull on cooler or radiator; maybe a little lower (2c) temps at same fan speed, but also a couple dBA louder. A single fan running a little faster so it's same dBA as 2x fans on cooler move same amount of air and give the same CPU temp. Same principle applies to case fans.

It makes sense to use them as exhaust fans, where the filter should be removed.

 

I've got a Meshify S2 and I originally removed both the top and front filter but ended up putting the front filter back in. Temps weren't meaningfully higher with the front filter removed.

I have my LF2 mounted in the top as exhaust so I'm still running without a filter there though.

@Piers I was referencing the back exhaust grill. But, yeah if I was personally using a Meshify, I'd remove the foam filter in the front.

 

The front filter is not foam.

 

Meshify grills are designed to be aesthetically pleasing to the eye way more than than for function. Same goes for most if not all case design. They go for what will sell, that's what most buyers are basing purchase on. Most buyers have little to no knowledge of airflow.

We need keep in mind how little force fans make. If your fan is rated at 1.8mm H2O, it has the same pressure differential as there is between pressure on your ankle and neck (5 feet difference in elevation = 1.8mm H2O difference in pressure). A fan causes air movement (or 'flow') by creating a pressure differential, which cause air to move from the area of high pressure to the area of low pressure. But fans have very low pressure differential, so little it's measure in mm H2O .. so we end up will very little airflow that almost anything will disrupt / restrict. Even things as small as strands of hair disrupt smooth airflow thus creating turbulence and reducing airflow, so with almost no force to start with things as small a stand of hair disrupt/restrict it.

 

I don't think there are any component built system components designed to have seperate component airflow. Only systems I know of that do are Apple Mac Pro, and they are pre-built systems.

I've done a few systems over the years with a divider between CPU cooler and back of GPU thus separating case into 2 compartments. I've used 2x & 3x 140mm front intakes and sometimes bottom intakes into GPU compartment. I duct from bottom 2x 120mm bottom intake fans to GPU's 3x 80/90mm fan shroud so GPU exhaust was separate from it's intake. While it works fine it's time consuming to build, even using file folders as material for duct and rattle-can painting to make even stiffer / more durable. Haven't done on a several years now and lost pics in crash awhile back.

GPUs, even ones with blower coolers don't seal heated exhaust from chips to exhaust ports .. not to mention how loud they are.

I've seem a few peeps mod CPU coolers onto GPU with good results, but it's not an easy project.

 

So I built the system im not sure if I did the fan setup right though. I ended up switching the fuma 2 out for noctua d15 it provided a bit better temps. I bought the mounting bracket for lga1700 just in case. My temps are fairly good 65c to 75c in gaming 85 90 in prime avx. My fan setup I left the 2 stock fractal fans in the front as intake and the stock exhaust fan and added two noctua nf p14 up top as exhaust and that’s it. My 3090 is 75c gaming max though. I do have two noctua nf p14 fans left though because I ordered 4. Is there anything I should change like the exhaust fan to a noctua add a bottom fan switch the front. Just asking. Overall I’m pretty satisfied
