Will A Magnetic Dust Filter Damage Psu

What is the final give-and-take on whether magnetic dust filters tin can or cannot damage hardware?

I am thinking of buying a 750D Airflow Edition case.

However, I've read that that the increased airflow comes at the cost of increased dust inside of the reckoner.

Some people accept recommended to cake that dust with magnetic dust filters.

But non everyone agrees that magnetic filters are rubber to use near hardware. While some say that those magnets are likewise weak to have any effect on hardware, others say that they are strong enough to impairment hardware a niggling chip, and that the damage accumulates over fourth dimension.

Then I am not sure who to believe. One side of that argument obviously doesn't know what they are talking almost. How do I know which side is right?

Tin can someone please tell me a definitive answer that I tin trust every bit to whether or not magnetic dust filters can impairment hardware at all (even if they tin do but small amounts of damage, and then I even so want to know about it)?

Cypher inside a PC will be damaged past a static magnetic field, particularly ane from a tiny little magnet many cm abroad. Not even HDDs will be affected.

I have an EE caste if you want that to audio more trustworthy!

• #iii

Thank you for the info. Yeah your answer does audio quite trustworthy, which is exactly what I'g looking for.

But I don't actually know anything about magnetic fields and when they are static or not static.

Are you saying that magnetic grit filters always take a static magnetic field?

That is right.

The central point is this: the manner that a magnet tin can affect electrical circuits is that there must be Movement betwixt the magnet and a wire. That motion causes a current to be induced to menstruum through the wire, and hence through other parts of the circuit. A magnet that is NOT moving and excursion wires that also are Non moving cannot have this problem. That is why Mr. Evil used the term "static magnet" to hateful a magnet that is just sitting in one place.

Fifty-fifty at the time that you are moving the magnetic filter mount around to identify it over the vent holes, the long distance from that to the nearest excursion, plus the small size and strength of the magnet, means that his effect is much too pocket-size to crusade a problem.

The only other way a magnet can bear on your arrangement is if it comes close to a device that has magnetic signals stored on information technology. In that case the magnet might alter the stored magnetic information. Now, the only types of devices that shop info magnetically are floppy disks - and I bet you lot do Not have any of those! - and hard drives. Merely the disks inside difficult drives are already well shielded by their cases from any outside weak magnetic fields. Thus, once more the magnetic filters cannot affect your difficult drives.

I have a lower front intake filter with 4 tiny corner magnets holding it in place. Find something else to worry nigh.

I thought of 2 possibilities in OP's question: either he was talking virtually magnetic tape used to hold something like a DEMCiFlex filter, or some sort of device with a magnet that traps grit. And I wouldn't know annihilation but my imagination about such a device.

I've started using 2mm-thick magnetic tape ($4 at Dwelling house Depot for a curlicue) to secure cold-cathode lights in my case for like shooting fish in a barrel removal and replacement. The case itself -- an old Stacker 830 midtower -- uses your standard ferrous magnet in the aluminum example design to secure the swinging forepart-panel door.

In that location was a time many years ago when I balked at using a magnetic screwdriver when it seemed needed to go a screw into a tight place, for fearfulness of borking a hard disk. A long, long time agone.

If this makes y'all feel better when I was in It I started collecting all the HDD magnets for fun, we had them all over the office. Walls were scratched, fingers were pinched, other difficult drives were killed while turned on, much fun was had. Once I stacked a bunch ane on top of each other. I stuck the whole thing right on my PC case. All you hear is Bang equally it violently gets attracted. Freaked the dominate correct out when I showed him that. Simply it did nothing to the computer as long as it was kept away from the actual hard drive... When I did kill a hard bulldoze on purpose (one that was beingness replaced due to already starting to fail) I pretty much had to stick the magnet within an inch of it.

That said to be actress condom I would probably not employ those magnetic dust filters anywhere near hard drives, try to go on like several inches at least. Chances are those magnets could touch the drive and it would yet be ok though simply better rubber than pitiful.

The case you're looking at does not accept filters and you want to add together custom ones? Might be worth looking into cases with built in filters that are easy to remove and clean. So much easier. And the fit volition be tight.

Peradventure I haven't kept up with the offerings, merely I'd seen at least a few cheap cases (and Coolermaster among them) which had "removable filters." Only they were still a pain in the ass.

the DEMCiFlex filters look unnoticeable or actually almost fashionable on my steel case, and they were custom designed for it. You merely need to pull them off, run them under the cold tap, dry out them and hang them back on.

I'd likewise posted some pics suggesting how you could make your own, with the correct option of polyester mesh material. Just I don't remember I'm going to worry much most magnetic tape -- certainly not on the outside of a steel example, but nor would I worry about it on the within of my aluminum example. I don't think I should worry if it's half dozen inches away from a 2.5" HDD, either.

The case you're looking at does non accept filters and y'all want to add custom ones?

The instance I am talking about does have grit filters, however they are pretty open. I accept read comments in reviews and on forums nigh that case which says that the dust filters are too open and therefore let too much dust enter into the case.

Here is a video that shows the meshed front and the low resistance dust filter:

I am trying to find out whether I should buy DEMCiFlex filters for information technology or non. Based on the posts in this thread, I'm going to presume that the magnetic part of those filters cannot harm my hardware.

However, I also have these questions:

Will using the DEMCiFlex filters be worse for my hardware because they will impede airflow in comparison to if I do not use them?

Volition using the DEMCiFlex filters be better for my hardware even though they impede airflow, because if I do not apply them, then the dust within of my case will be worse on my hardware than would be the diminished airflow that would happen if I did use them?

Ultimately, I want to exercise what is in the best interest of having my hardware terminal for equally long every bit it perhaps can. Which option is more likely to aid that goal: DEMCiFlex filters or no DEMCiFlex filters?

Dust volition not injure your calculator. Never cleaning the grit out, and allowing information technology to clog your fans and heatsinks is what could cause harm. And unless your room is very dingy, or you smoke in that surface area, that takes a off-white amount of time.

I use the standard filters that came with my Fractal Blueprint R5, and fifty-fifty later on a full yr, I haven't had to clean the inside out. How is that possible? I go on the room that information technology is in clean, clean my filters every 1-2 months, and I take my PC set up with 'positive pressure'. In simpler words, I have more than intake fans than I have exhaust fans, therefore dust is not bypassing my filters through all the small gaps on my case.

If in another yr I run across dust starting to collect in the example, I'll simply blow information technology out. Information technology's really not a big bargain, and you don't desire to over think information technology.

It's squeamish that you lot intendance nearly preserving your hardware, but y'all worry too much. Because the corporeality of inch-thick dust layers I've seen within of diverse PCs, it's not the be-all, end-all of PC killers. Just keep yours reasonably clean, and don't let dust accumulate. DEMCIFlex filters are very overnice, I use a few myself. They don't impede airflow in any noticeable (and probably measurable) fashion. I'd become that route if I were you.

I've got multiple cases correct at present who's dust filters are held on magnetically and came that way from the mill. NZXT H440 also as several Silverstones. I've also used lightly magnetized screwdrivers to piece of work on computers for nearly xv years. Never had an effect with either.

I've got multiple cases correct now who's dust filters are held on magnetically and came that way from the factory. NZXT H440 as well equally several Silverstones. I've likewise used lightly magnetized screwdrivers to work on computers for nearly 15 years. Never had an issue with either.

Definitely not the gamble of Walter White's attack on the police testify room in "Breaking Bad."

The DemciFlex filters use that brown magnetic tape. I apply magnetic tape to agree my cold-cathodes in place inside the case. I know that filtering restricts airflow, merely fifty-fifty if I make clean these systems out once a week, no thing the amount of attention you requite to bravado them out, the dirt begins to grow.

• #17

I've been doing more reading about the Demi filters and then I establish this directly on the Demi site:

Filter rating: F
This rating will depend on the filter rating you are using. This is expressed every bit a percentage and is indicated on the packaging. Case: If the filter rating is 15 it volition inhibit 15% of the air from entering the computer case. This sum will have to be added to the required CFM of air needed for the intake fan(due south) to compensate for the loss of air. Let'southward telephone call the filter rating value F. Remember that this is a per centum value. DEMCiflex Filters are rated at 20.

Am I agreement that quotation correctly: I believe Demi is saying that their filters inhibit airflow by 20%. Is that right?

That sounds like a huge, deal-breaking amount to me.

Would the loss of twenty% airflow not definitely brand using the Demi filters a bad decision?

Or am I missing something?

• #18

Whatever kind of filter is going to impede air flow. I've never taken actual measurements so have null to really compare to, only 20% does not really sound that bad. It depends a lot on the fans also, some fan designs are improve at dealing with static pressure vs others. As the dusts pickup dust the airflow volition exist reduced more so you do want to clean them regularly, just similar changing your furnace filter. (speaking of which, I remember I'm due to change mine lol)

Even if that reason wasn't the basis for my thinking and practice, I've always inclined to over-powering the intake airflow. Yous don't filter the exhaust air. So I generally figure that if my intake gauged simply past the CFM specs of the fans is at to the lowest degree double the frazzle CFM, filtering is only a useful encumbrance. And filters don't catch everything. Y'all will detect a much finer layer of dust on components with decent filters, and you still need to accident out the example with compressed air or a Metro 500 in addition to merely cleaning the filters.

• #20

A static magnet really tin can mess up the data stored on a HDD. But it has to be a very large magnet. I have personally corrupted a difficult drives information with the HUGE magnet on the back of a 12 inch subwoofer. Merely this magnet weighed like 30 pounds. I likewise damaged a CRT Telly from the magnetic field of a subwoofer magnet. Only aye the teeny tiny magnets on dust filters has admittedly no effect on anything inside the PC. Retrieve of apple tree laptops with the magnetically fastened power cable. They have been using that for years without a single issue and it is closer to the HDD so a dust filter on a big belfry.

You will find a much effectively layer of dust on components with decent filters, and yous nonetheless need to blow out the case with compressed air or a Metro 500 in addition to merely cleaning the filters.

I observe with magnetic filters you have to accident the grit out MUCH less often. On my current PC I only have to blow information technology out one time every 2 years and even later on 2 years its a very fine mist of dust that gets blown out. I have a silverstone fortress ft02 on an lga 1366 i7-980x system with the 3x 180mm intakes and 1x 140mm frazzle.

Sounds about correct to me. Nosotros take a lot of dust here on this hill in So-Cal. A So-Cal Gas company employee in one case visited the house to run tests for maintenance and safe. He said we had the cleanest air of any business firm he'd e'er visited. Sure! We accept almost iv computers running with filters.

Merely like you said, finer particles eventually find their mode into the case.

• #23

Nothing inside a PC will be damaged by a static magnetic field, especially one from a tiny piddling magnet many cm away. Not even HDDs will exist afflicted.

I have an EE degree if y'all desire that to sound more trustworthy!

How many cm away until something would be damaged?
