    I have always loved this idea
    Intake air is bubbled through a water tank, trapping al dust and other nasty things, a fine wire filter on the intake would prevent bugs and stuff getting into the water. the air is then extracted from the top of the tank, above the water, into a computer case which his total sealed off from the outside, apart from a 400 fan at the rear, which is doing all that work.
    Cooler the water in the tank, cooler the air entering the case, and if the case were constructed from toughened glass and if the exhaust fan had a flap that sealed it, if the fan stopped. I reckon it could look really cool
    If only I had the time to build one.
    Mineral oil, nice idea, but very messy when you want to rig it a different way or want to upgrade etc. I'l keep to using that on my chopping block thanks.

    Not a correct test . Not all cases have the same amount of fans on the same spot . I even see one case without fan in the bottom . Oneven conditions have uneven results.

    makes me laugh, got a new case yesterday for water cooling, it has dust filters on top and front where the radiators go, not wanting to blow the hot air from my radiators back into the case that makes these filters redundant, the rear fan is also sent from the factory blowing air in accross the nb area (which is what you want if everything else is l/c and there is no dust filter on this fan, what kind of fuckery is this? is my pc just an air conditioning unit to keep my house dust free?

  • chuckyz2
    chuckyz2 21 day ago

    The one that had all out was the best. You just left the intake on the back unfiltered. If there was a screen on that one it would have been much cleaner on the inside. Anywhere air comes in should be filtered. No need for filters on exhausts. And the filters should be able to keep any dust from passing through. Computer filters seem to all be to porous. Yet if paper filters were used, then more maintenance would be required. Flow would be reduced also.

  • Matt West
    Matt West 22 days ago

    Very interesting results! Especially surprised by Inny myself!
    Also, not even joking, In all these cases, that is, with variance.
    This is how much dust I get through / stuck on my air filters on my computer in 1-3 weeks thanks to my parrot lol xD
    It is a nightmare! I even covered up all the chassi holes around the case to force air through the filters.
    Air compressor is a must lol!

    4th year of using two NZXT H2 cases with identical setups of 3 fans in and 1 fan out, a push-pull configuration on the CPU and blower-style GPU fan... The little dust that came through after cleaning the filters once in a while are insignificant. I taped the honey mesh as well as the expansion brackets on the back just to avoid air getting sucked in where its not supposed to get in.
    I live in an apartment with my wife, a kid, 3 cats and some friends visiting every now and then. Think I have opened my PC to clean it 3 times since I bought the case 4 years ago, but I never had to clean neither CPU or GPU. The tiny amount of micro-dust that actually comes through gets stuck on the GPU PCB, which is the only thing I ever clean in my PC. Didn't open PC to clean it, but to replace thermal paste and pads, dusting off the GPU while I was in there just because.
    Good case, NZXT did a great job with this one! :)

    LeitoAE HachiRoku 24 days ago

    Well.. The inbetween setup definetelly needs dust filters more often to be cleaned, because they work as they were designed to. When you have fans to pull air out of the case you don't need dust filters at all, because all you did with those filters you filtered the air that was going out of the case, and you keept the dust between your case and dust filters...

    Clearly neither of these guys has tried to clean computers owned by smokers with pets. The cig tar turns into a glue almost and the fur becomes like sticky furry dryer lint. It is truly awful. I told my step-father (RIP) to get his off the floor, so he put it up on his desk. Better, right? Well, not if you put your ashtray right in front of the intake fans. And you smoke a ton. After a year the inside was like black honey dripping off everything. I pulled the HDD, threw the system in the trash, and got him buy a new one.

    Takeaway...
    1) smoking is terrible for you, and not good on your PC either
    2) smoking, pets, and computers don't mix well
    3) trying to clean smoky, furry, tarry computers IS NOT WORTH IT. It can never be cleaned enough.

  • kart0ns

    best would be to get average temps over this year for all 3 setups, dust is one thing, but thermal efficiency is greatly dependant on how clean fans, filters and radiators are

    Try having a bird room with 6 budgies and then place your desktop 1m away from the bird cage and birds get to fly around the whole day... 3 months in and I could make a pillow out of the dust I get in there! The dust comes from their seeds, vitamins, skin, the material around their brand new feathers, the wood pieces on their cage floor, stuff they shred etc. lol Your towers look clean compared to mine after 1 month! lol And my air management is mixed (in and out). I clean my pc every 2 months or whenever my pc starts restarting randomly :D The tower runs only 3 to 5 hours daily! :D

  • Bob Saget
    Bob Saget Month ago

    I'm thinking of removing my glass side panel, and using a perforated piece of sheet aluminum, cut and drilled to fit and hold a fan on a bracket to suck air as well as from the front, exhaust is top and back, three fans. Planning on also putting a dust mesh on the outside, but my question is, would this be good or bad? The fan would have to be placed perpendicular to the inlet flow from the front, and since the panel will freely flow air, there wouldn't be much "pressure" inside, to allow a particular direction, so would the idea of having the "exposed" side allowing ambient temp air to seep in and exchange freely be beneficial, or should I just leave the glass on and let the air flow of two 120mm intakes from the front do its work?

    You use all in-y except you put filters directly onto the fans. That way all the air that's getting pulled into the case is getting filtered and being pushed out elsewhere keeping the dust away

  • nobody
    nobody 2 months ago

    all out fans (neg pressure) works great if you do it right, i have it all out the back and a filtered air intake high up on the side (and yes the blower, blowing out on the floor of the case), not much dust gets in.

  • Turrebo
    Turrebo 2 months ago

    I'd say filter the incoming air, but not the outgoing air.
    Eventually the filters for air out will get clogged, thus preventing a good air flow.

    Or you could -dust- just clean the filters from time to time. I don't know. I thought RGB would fix everything.

  • rchew2 TehBecks
    rchew2 TehBecks 2 months ago

    Outy is seriously flawed, you didn’t have any fans in the bottom... so the negative air pressure turned the bottom filter into an intake for Outy

  • Frédéric Jeanbart
    Frédéric Jeanbart 2 months ago

    Quite interesting thanks! To see a negative pressure case staying relatively clean considering where it was (I would've guess that it would've been full of dust). It looks like with a "very" negative pressure, it's sufficient to blow out the dust and keep the case clean inside. 3:20: have you guys open the GC, just to see if there was a dust built up inside (since it looks like a blower card rather than an open card)?

    Pretty sure that "Outy" should mean that there is positive air pressure in the case blowing air out, not negative pressure external to the case sucking air out.
