Looks like speedfan might be able to control voltages!  So you're not totally out of luck.

Hey, so I just got some new dust filters for my PC since a lot of dust used to enter the case, but the dust filters have little to no effect to prevent dust entering the PC, I have to clean my PC every single day due to this, and within no time there's so much dust accumulated on the PSU shroud.

 

Case: Phanteks P300 Eclipse

 

Fan Config:

2 x 120mm Intake (Front) (With Dust Filters)

1 x 120mm Exhaust (Top)

1 x 120mm Exhaust (Rear)

 

Thanks in advance!

May want to address the dust in your home, if you're cleaning every day.  Sounds like you have a much larger issue.


Also, PC dust "filters" are mess screens.  Not true dust filters.  Take out the filter in your furnace to compare.  They can help with dust but they still suck.

 

Again, if you have that much dust in your PC you have a problem.

The only place where the dust sits at are on the PSU shroud, tiny specks of dust to be precise. Other than that , rest of the PC is flawless. There's no dust on the GPU backplate too.

You're never not going to have dust. Filters or not. If you let your PC go for years without cleaning it out, then you'll have issues. Otherwise, it's fine as is. The tiny specs here and there aren't going to hurt it. If you really want, clean it out once a month or so - that should suffice.

Yeah I guess you're right, I'm probably nitpicking way too much lmao.

I've attached a couple of images.

What's your fan config?  Is it pretty balanced, maybe with a bias towards fans blowing air into the case? Is your case on the floor with fans sucking in air from the bottom?

Check out the main post! all details there!

Anyway,

Fan Config:

2 x 120mm Intake (Front) (With Dust Filters)

1 x 120mm Exhaust (Top)

1 x 120mm Exhaust (Rear)

 

PC is on a desk.

It seems like you have a slightly negative pressure. While there are the same number of intake fans as exhaust, the intake on that case is restricted in comparison to the exhaust fans. Perhaps try and increase the intake fan RPM / decrease the exhaust fan RPM?

Will have to check that out, the fan curve settings in my BIOS seem pretty intimidating to me.

If your fans are pwm fans (they have a fourth pin on them) and your motherboard fan connections are pwm (your board looks like an asus tuf board, so I'm guessing so?), you could control it using software instead of the BIOS https://www.howtogeek.com/275339/how-to-auto-control-your-pcs-fans-for-cool-quiet-operation/

And looking at the case, I agree with copacetic that you likely have some slight negative pressure, since your front fans aren't open to the air like your exhaust fans are.  It's one of the reasons I went for the phanteks enthoo pro m.  Not even sure if the front fans are filtered, but I don't get much dust in my system.

Nope they aren't PWM unfortunately since I cheaped out on good fans. board: MSI B350 Tomahawk.

sad day :( Looks like the motherboard supports fan voltage settings thankfully.  Assuming they're not too loud, you could try setting the intake fans at a static percent, and leave the exhaust on auto.

Yeah that's the best bet I guess. Thanks anyway!

aaagh lol!  Looks like the speedfan software works with non-pwm fans.  I edited my response because I didn't want to double post

So intake at 100% and Exhaust at AUTO? 

Any recommended settings for these?

Fan Config:

2 x 120mm Intake (Front) (With Dust Filters)

1 x 120mm Exhaust (Top)

1 x 120mm Exhaust (Rear)

you can start there and, depending on how loud your fans get, maybe try setting them down to 90 or 85.  Just keep an eye on your temps.
