Actually, I’d recommend a moderate positive pressure to keep dust from coming in through every opening in the case.
Your link actually takes you to the Arctic 280.
Arctic arguably make some of the best AIO around at the moment. I use an Arctic 38mm Liquid Freezer 120 on an i9 9900 without any issues. I doubt any other 120mm cooler other than possibly a H45 Corsair could handle a 9900K .
Good enclosures have clip on filters that can be easily cleaned without removing covers. That’s what I have and the filter gets cleaned every 2-3 days. Too many enclosures are badly designed unfortunately making dust prevention difficult.
Dust in my systems tend to accumulate on the base of the enclosure but not on components that generate heat, that’s because I have lots of air which stops dust accumulating within the path of the airflow. I base my cooling systems on my professional power system designs to ensure that dust is not that much of an issue. With professional industrial power systems, cleaning out dust just doesnt happen so designs have to reflect that.
Thanks I’ll change that and I agree the Arctic are one of the best if not the best AIO on the market. I couldn’t find anything to keep my 5900x cool until I ran across them.
With enough 120mm fans in the case overheating is not really a problem, not even in summer.
I would not recommend running the graphics card in passive mode (no fan mode) while not gaming because it is getting really hot without fans (55°C or more). A hot graphics card is heating up the whole computer and especially the NVMe direct above the backplate like a cooking plate.
Having the graphics card fans running at lowest settings while in idle makes no noise at all but the graphics card will stay almost cool to the touch and NVMe and RAM will be a lot cooler.
And the CPU fan makes way less noise in a cool tower.
Positive pressure helps insure all air comes through the filters and none is sucked through random openings.
Yes what do I know? I only design high power industrial power systems in enclosures for a living, that could not possibly give me any sort on insight into how to cool components in an enclosure.
Cool I pump gas for a living and no dust accumulates on the base of my PC.
I dont care about dust on the very base of the enclosure, that doesn’t matter, the important thing is keeping it off of the semiconductors that need to be cooled.
OverClockers did some tests and they concluded that there was no benefit in having positive, negative or near neutral presure as far as dust build up was concerned. Their tests showed that just plain old regular maintenance was the best way to deal with dust.
As far as dust goes, avoid sticking your PC under the desk sitting on the carpet , is the first step.
One advantage of the LED lit Wraith Prism cooler is you can actually see any buildup of dust on the cpu heatsink (it always looks worse than it is).
Anybody interested in my bargain priced magic dust cloth?

What a sham…wow
Props to ya. I’ve been using Asus motherboards since the 90’s and they’ve never let me down.
Really happy with the 240mm Corsair H100i Capellix that I installed last week for my i7-11700KF.
I ran the Cinebench all-cores test for 10 minutes a little while ago and the highest package temp peaked at 73℃ after 10 minutes. Coolant temps were about 38.5℃ at the end of the test. I’m annoyed I didn’t think to make a screenshot. D’oh.
It may not be the best but it sure is good. I got quite a bump switching from the MSI aio.
I did some more case tweaking. I have a plexiglass front and top. I also discovered the top fans were intake. I removed the top and front plexiglass. It’s kind of interesting and ugly with the exposed fans.
Anyway, the top ventilation whether it’s in, out, glass on or off does not really seem to make much difference that I can tell within margin of error. It could just be a closed top. Top off with fans out may bump it .5 C but it’s hard to tell.
Removing the front plexiglass however made a big bump, around 7 to 8 degrees C. With this config I’m able to keep the fans near silent and the sim running in the 50s and 60s. When I first posted in here I was holding up at 90 C. Changes in order of impact were:
- new thermal paste (biggest help)
- Swap to Corsair aio
- Tuning curves with Ryzen Master
- Modifying the case and tuning the fans
When did this trend of putting figurines in the case start? People are finally taking their toys out of the box and putting them in the case.
Wife bought it for me for my case so I put it in there. First time and only time I’ve done this or thought about it.
My son is thinking of taking his Saitama (One Punch Man) out of the box and putting it in the case I just built for him.
If I ever do a white case I’ll put Darth Vader in it.
That’s really cool… Yes Vader would be interesting in an all white case for sure.
