I mean, it will get air in some how because of the 14.7 air pressure even with no intake fan. Air will still be drawn in because the air gets pushed out the top and the back. Most of the air gets trapped in the top and back of the case. They still get dirty. All fans get eventually dirty. The solution is to add a mesh filter to the intake side so you can just wipe it every now and then than trying to pick it off from every single blade and trying to suck more out with the strongest Dyson vaccuum. Even doing it that way stuff will still remain.
The idea is to think of it like you are in a sealed house that is hot with all windows closed, a fan blows on you and you still get cooler.
That's a completely different mechanism in most cases, unless your CPU sweats.
I find compressed air to be much more effective than just a vacuum. When the avg cpu temps get to a certain level I take the computer out to the garage and blow the dust out. I used to do it inside the house, using compressed air to dislodge the dust and a vacuum to suck it up. But the vacuum doesn't get everything so it just made more sense to take it outside.
Not sure what you're getting at here, especially with the outer space stuff. That comment was that the reason you feel cool even if a fan is blowing hot air on you is that you're perspiring, and you cool off because the sweat absorbs heat from your body to evaporate. Your CPU obviously doesn't sweat.Any fan in the entire world will dust up. Stuff falls from outer space and spreads out and it collects that dust. It collects dead skin dust. It collects carpet dust. It collects dust from outside that goes onto the clothing. Unless you have a super clean room and body, there is no way it won't stop collecting dust to the point where it matters. I use the PC all the time. It never turns off. I added a mesh to my radiator fans and all that has to be done is to wipe it. Sure it might block airflow faster but it's either that or removing the radiator fans then cleaning the inside. Maybe a small rechargeable USB vaccuum would be the solution to clean this up quick.
In regards to this, it's IMO still a little sketchy to be vacuuming inside your computer while it's running, simply because most vacuums produce so much static. If you want to do this, a really effective way is to flip the fans around on your radiator and mount those filters on the top of the radiator. You're then drawing outside air into your case through the filters (and rad), and letting it diffuse out through all the holes in the case. Because it's positive pressure dust is much less likely to enter through all your system vents, and when you do want to clean it you just need to pop the top off and vacuum the top of the rad rather than stick the vacuum into your case anywhere near your motherboard or GPU.yeah but I want to actually clean the dust while the PC is plugged in an online
I'm a big fan (haha) of having tons of positive pressure, seal up any unused vents, and force air out one or two different spots. The filters would go on the intakes. In the case of water cooling I'd probably have the rad sitting externally, as if it's internal, then what's the point of even doing water cooling if you're still relying on case air flow to keep the water cool, may as well just do pure air cooling. If you really wanted to geek out you'd have the rad in a completely different room. Or a central water cooling system that does all systems. That would be something fun to build actually but a failure would be catastrophic.
Ahh, I missed that detail from your earlier post. Sounds like a good solution then. Accepting the steady restriction of the screen to prevent the fans from getting super dirty. I wonder how restrictive the screens actually are. It would be an interesting test; measure the amperage drawn by a fan with and without the screen.
