  • I finally have an AC unit so temperature controlled environment invites some case

  • temperature testing one might say quarantine hair yellow good people I'm

  • Dimitri and what we have here on the review table is the be quiet pure base

  • 500DX we saw this case CES and I gotta say what they've done here is both

  • competitive affordable and I'm hoping more companies follow and what be quiet

  • is doing here the 500DX is basically an airflow iteration of the pure base 500

  • you can check out that review over here but the guts remain identical with a few

  • exterior changes that make this a very competitive and an airflow excellent

  • enclosure so now that we find ourselves in a temperature controlled environment

  • I want to do some airflow testing both move some fans around add some fans and

  • see what is the most optimal fan configuration for an airflow focused

  • enclosure like the 500DX with my airflow system configuration and the

  • reason why I think this testing will apply not only to the 500DX but many

  • other cases in 2020 is because many brands are choosing the whole front mesh

  • panel and including quality fans so the 500DX for example comes with 3 140

  • millimeter pure wings 2 fans which spin at 900 rpm don't worry about the lower

  • rpm because the larger fan does move more air and having non-restrictive

  • front intake it gives us fantastic intake and also the 900 rpm gives us

  • that whole peak quiet operation which they're obviously known for so in this

  • video let's test out 7 different fan configuration options all using 140 more

  • fans just so that we can utilize what is already included with the 500DX and see

  • what fan configuration is best right after this the X299 CLX from asrock is

  • the best place to house your new core X processor it features aluminum alloy

  • heat sinks with dr. Mazda 13 phase power design for the best overclocking

  • experience it also has Wi-Fi 6 support 3m 2 slots along with reinforced PCI

  • brackets learn more down below alright so before we get into the air flow

  • testing let's quickly recap what is new on the 500DX so

  • see the front panel mesh is new we have quite high density of the holes in both

  • the left and right side with that a RGB strip in the middle and I do find their

  • illumination implementation inside this enclosure quite tasteful plus we have an

  • internal RGB strip inside the case that is not visible when the side panel is on

  • and it does help to illuminate whatever is in the top section on the case and it

  • does actually spill to the bottom all the way through the glass creating this

  • like pretty cool line at the bottom I also really like how it illuminates the

  • power supply shroud corner so it helps to separate the internal sections I

  • think it looks quite nice obviously you can change the color and modes of this a

  • RGB strip with a button up top and here we also find a type c connection only a

  • single USB 3 port and i really do not like this pattern and this direction

  • that many case brands are now doing now the good thing about the front panel is

  • that we have pegs instead of wires that connect the main panel to the contacts

  • on the chassis but it's really difficult to remove this thing and one more thing

  • when reinstalling the panel make sure all three pegs are making contact with

  • that frame because otherwise this front illumination will not light up so behind

  • this front mesh we have a dust filter spanning the entire portion of that

  • intake and we also have a bottom dust filter removal from the front without

  • the need to remove the front panel first nice the glass panel is attached with

  • the regular thumb screws and the rubber bits on the frame stay with the frame

  • they're glued there and they don't fall out when you remove the glass panel

  • which was the case with a dark base series as for the top panel we no longer

  • have the closed off section that we only have the mesh magnetic plate and behind

  • it you can install dual 140 s or 120 s and their respective radiators as for

  • airflow at the front you can do triple 120 s or dual 140 mm fans with their

  • respective radiators too as for the interior nothing has changed here ATX

  • motherboards support a perforated power supply shroud doula says these beside

  • the motherboard and this nice little cable covered

  • heids whatever is exiting from the back and the right side panel has some noise

  • dampening form applied to it that helps to compress some of the cables and just

  • really dampen whatever is exiting through the right side of the case I

  • don't really have anything else new to say about the 500DX so now let's begin

  • the airflow experiment I kept the room at 22 degrees Celsius I

  • have this thermal meter with dual temperature probes one that kept on the

  • outside of the case to measure ambient temperature just to make sure that my

  • control point was on point and correct and fluctuations for that temperature

  • probe was only 0.1 degrees Celsius I'm very happy about that

  • and the second probe I kept right above the VRMs on the motherboard just to see

  • if a hot pocket would accumulate there and if you add more fans or remove fans

  • what will happen to that space so first let's establish a reference

  • point with our default fan configuration out of stock cooling here we have 74

  • degrees Celsius and 78 degrees Celsius on GPU and CPU respectively these are

  • pretty decent temps and that front panel is not a massive bottleneck for air flow

  • so we only drop one degree Celsius on the GPU and two degrees on the CPU but

  • that front mesh removed now removing the dust filter as well so we have totally

  • unrestricted intake we do drop slightly on the CPU but the GPU remains the same

  • 73 and 73 and the really interesting thing about the noise profile with a

  • dust filter and the mesh removed is they do dampen this sound a little bit but

  • it's basically like it sounds like an open and closure already which is why

  • having lower rpm fans helps a lot this machine behind me has six fans

  • running and it's very quiet actually the fan on my light is louder

  • I can hear it more than the system with six fans in it so let's see if we can

  • move some fans around and get better temperatures so the first thing I wanted

  • to do is move the top fan to the front so both the CPU and GPU have that nice

  • fresh column of air and as expected that fresh column of air does actually drop

  • our CPU temperature by three degrees and only one degree on the GPU and this is

  • without adding any fans we're just reconfiguring what is already here am i

  • testing previously with cases like the H510 from NZXT having dual exhausts

  • one at the top one in the rear does actually help with CPU temperature but

  • that case has a pretty restrictive front intake whereas here it seems like that

  • benefit of having fresh air intake and having like plenty of exhaust at the

  • back is enough to drop our CPU temperature by a little bit and I

  • welcome that but what if we move those front fans to top exhaust and this

  • actually surprised me quite a bit because our CPU temperature actually

  • increased to 79 degrees Celsius that is higher than our default control point

  • and the GPU temperature also increased by a degree so it seems like having no

  • intake inside the 500DX is not a good thing and having everything being

  • exhausted isn't enough to cool whatever is being accumulated inside the

  • enclosure I then decided to flip the top fans to intake air and a CPU temperature

  • did drop to 78 degrees so back to our control point but the GPU actually

  • increased in temperature I'm guessing there's just nothing to remove whatever

  • air is being accumulated at the bottom and finally let's populate all 140 ml of

  • fans thoughts in here having to the front to the top and one for exhaust so

  • I kept the top fans as intake and having two front fans delivering air so there's

  • a lot of intake happening here and both the CPU and GPU temperature has reached

  • a 74 degree equilibrium giving us the coolest CPU temperature 74 degrees

  • Celsius but still not too far off from the 78 degree of our control point and

  • finally I rotated the top fans as exhaust and weirdly the CPU temperature

  • did go back to 70 80 degrees Celsius while giving us a nice cool GPU staying

  • at 73 now what about that internal temperature probe above the V RMS and as

  • you can see this space is only adequately cooled when there's intake of

  • air either from the top or the front with the good balance of temperatures

  • when we reposition the top fan to the front but what's really interesting here

  • with the top fan set to exhaust this area becomes really toasty because of

  • competing airflow streams between the lateral CPU cooler and vertical top

  • exhaust so something that should be mitigated if you rotate the CPU cooler

  • and it seems like for this type of Tower if we don't have enough front

  • intake GPU temperature suffer and if we don't have enough top exhaust GPU

  • temperatures suffer again and the most interesting thing here is that if we

  • have all fans populated the best configuration is have both top intake

  • and front intake as well gives us better CPU and GPU temperatures at 74 degrees

  • Celsius but the second next best configuration is to simply move that top

  • fan to the front intake which is pretty surprising but then maybe we're

  • encountering the law of diminishing returns of like adding too much air flow

  • where the components are adequately cooled already out of the box for my

  • concluding remarks this whole thing has been quite interesting being in a

  • temperature controlled environment and playing with some variables to see what

  • happens with our GPU and CPU temperatures and the most impressive

  • thing is you don't need to buy any more fans simply relocating the top fan to

  • the front will improve both GPU and CPU temps and if you really want to go all

  • out and having the best temperatures inside this enclosure then in my testing

  • having intake at the top is better than exhaust for the CPU and as long as you

  • have adequate intake for the front GPU temperatures will not suffer so I hope

  • you guys enjoyed this one I'm really interested to test this type of airflow

  • configuration with many other airflow mesh front enclosures coming up in the

  • future like the Phanteks P500a coming out something from Lian Li with the LANcool 2

  • so yeah let me know in the comments what do you think of this experiment and

  • potentially move your friends around to see what gives you better temperatures

  • now Dimitri thanks much for watching check out this how the relevant content
