is it to go from a solid front panel to a mesh front panel when you've got high-end power-hungry hot components but then we got some really anomalous data how could adding knock to a fans all over our mesh case possibly put it in a position where our GPU is running at the same temperatures as this here hotbox the only way to find out is to use our new smoke machine hit me with the smoke poof smoke me that is weak that's all it's got i told you guys to get the good smoke machine we did the other one well anyway there's a dead spot you can see it we'll get you more details in a minute and this video is brought to you by microcenter who sells of course both solid front panel cases and mesh ones so ultimately i guess they don't care which one wins which is good no conflict of interest to kick off our intended video mash versus solid front panels we turned to the nzxt h510 a case that was notorious for looking great but having very poor ventilation now to their credit nzxt did listen and gave us the h510 flow which is the exact same case just with a mesh front panel which means should be fine right just drill some sweet speed holes and bang boom you're off to the races well yes but actually no as you can see despite the flow's improved flow of air our core i9 12900k hits a hundred degrees on the package with the stock fans and even the mighty nhd15 cooler couldn't tame this 250 watt beast without us resorting to drastic measures we then swapped out the stock fans thinking maybe they were the problem for some knock to us which brought us down to 97 degrees which well it isn't exactly amazing but it did at least stop the thermal throttling that we experienced before unlocking the maximum performance potential of our CPU and demonstrating once and for all that mesh front panels are indisputably better than solid ones which don't allow any air through them no matter how many Noctua fans you install so why is this video only one third over let's talk about our GPU yeah we've got one it's an rtx 3090 and it did run a little cooler when we switched over to the flow but only by a few degrees then our 20 minute furmark soak saw temps rise steadily to roughly 79 degrees on the stock fans with the solid panel and then 84 degrees with the Noctua fans and the wait i know what you're thinking that can't be right but we triple checked in both cases while the Noctua fans markedly improved our CPU thermals they actively hindered our GPU thermals and there's nothing wrong with our nfa-12s they're great fans and available at your local microcenter by the way don't forget they sponsored this video so what the devil is going on here to start our investigation we're gonna dial things back a little and use a gaming rather than a synthetic load for our test we looped our f1 2021 benchmark for 30 minutes and we got better results seeing a drop of 6 degrees on the flow on our CPU and 7 degrees on the GPU so that's a solid improvement going from solid to mesh but then again we swap to our noc to a fans and the CPU improves while the GPU heats up though at least our mesh case still did manage to see better numbers than our solid front panel guys we are running exactly the same components in all of our tests yes we built and rebuilt these pcs enough times to need some refreshing ice cold water ltteststore.com and we double checked our compatibility with microcenter's custom pc builder tool we're gonna have everything in an affiliate link down below so what is going on here let's take a look at our smoke test with our stock fan setup it's not so bad air gets pulled in wafts all around our components with a good chunk getting pulled into our CPU cooler and some circulating around our GPU then it gets exhausted out the back it's clear now though that part of our problem is this huge graphics card in such a small case it's almost right up against our fans and you can see that the air gets pulled in and hits a wall causing turbulence when we swapped to our noctuas we thought wow these things are so quiet we could spin them faster while maintaining the same noise level but get this at such a high RPM the turbulence becomes even worse and we got small pockets of air in front of and underneath the GPU that were just recirculating being heated up multiple times before going anywhere you can see our CPU cooler is still getting plenty of fresh air so it's fine better than before even but it's pushed right up against our 30-90 not quite touching but not much of a gap for air to pass through either so almost nothing is able to circulate around the GPU's back plate more fans more better though right we certainly thought so but since now we have all this air intake but no extra exhaust there's only one spot for a fan on the top of the h510 and good luck getting a regular thickness one up there with our motherboard all this extra front fan ends up doing is putting even more pressure on the top stream and since it's blowing too fast for our CPU cooler to keep up with we also get some turbulence at the top front of the case where air cycles around for a bit before it can be vented out anything trying to come up from the bottom is instead constantly pushed toward the back so in a nutshell you can pull in all the air you want but if it can't leave or if it passes over a hot tower cooler before getting pushed down into your GPU you're gonna have a pretty bad time as the air heats up inside your case obviously there are a ton of other fan configurations cases and hardware to examine so make sure to get subscribed so you don't miss our upcoming LTT Labs content where we'll be exploring this in much more depth all of the side questing out of the way though it's time to revisit our original question mesh or non-mesh we chose a bit of an extreme example as the h510 only has this tiny strip on the side for airflow but it really was a huge difference look how little air we suck in through these side vents even with our intake heavy configuration even when we blasted our fogger more directly at the side vent it hardly helped so a mesh front panel at this point seems pretty obvious but pc building is often about balance and your own personal preference the more power you're after for work or gaming the stronger the components need to be and the hotter they might get so the better cooling solution is obviously going to be the best on the other hand if you've got a pc with integrated graphics that's meant for light office work or light gaming you probably don't even need to think about what kind of case and cooler you buy whatever you need though you can find it at today's sponsor micro center if their online builder tool isn't enough just head inside and ask for help from any of their knowledgeable
