SST-FF123W

Even water cooled pcs require air flow to cool off their reservoirs, and dust collecting in radiators is just as annoying for rigs that are all air cooled. My main gaming rig is housed in a Corsair Obsidian 800 case that I mostly cool via airflow from 3 120 mm top mounted fans and a bottom mount 140mm fan. I recently switched to negative air pressure (normally I prefer positive air pressure, but I saw significant cooling improvement by switching to negative) and purchased 3 new Noctua fans. I used to use a competitors air filter that had a hexagonal grid and was rated at being able to filter fine dust, while those filters did in fact do a good job, they had to be cleaned with increasing frequency as the filter material eroded with each cleaning. After some research of varying other filters, I decided to give the Silverstone Tek a try.Wow, what a difference. First off, due to the configuration of my box, these go on the top vent, I don't even need to screw them into the case as the magnet frame adheres my steel frame very snugly. Secondly, I did a smoke test to see how much the air was being moved with the filters present and when they weren't. Though I'm sure some hindrance was present, with the naked eye I couldn't see any, the fans pulled in air just as fast with or without the Teks in place. I did the same test with unused filters of the previous sort as I had bought a entire box of them at the time and was curious to see how those held up against the Teks. I won't bore you with the nitty gritty details, same smoke test, and I could see a definite impact on how much air was being pulled through, the Teks won hands down.Cleaning these things is a snap, though in part its due to how they're mounted on my rig, I just peel them off soak, rinse then air dry overnight and then slap them back into place with very little fuss. Someone who has actually mounted these with screws will have a more involved process obviously, but the filters themselves clean up very easily if you put a little effort into taking advantage of their features. As far as their performance at filtering dust is concerned, that will take a while to test but so far I've seen zero buildup on my brand new fans. I'll update this review in a month or so with further input.

While originally I purchased this product for its effectiveness and need, I found the customer service to be exceptional in providing quality support for a problem I ran into, with its dimensions and the space I needed it for. Overall, I appreciated their attentiveness and can recommend them for their product quality and customer support.

80mm gets 5 stars. 120mm gets 3 stars. Splitting the difference.I was surprised by this QC issue, as I had purchased a similar product at 80mm and it fit exactly right. The 120mm was off by 1 mm, which was enough that the provided screws did not work to secure the filter. If trying to screw on corner to corner, the filter bows and pops up in the middle. Didn't try sinking the screws any further, as it would have broken the filter. Fortunately I have an extensive M3 nut and bolt kit and was able to secure it with narrower fasteners, but for a non-enthusiast that doesn't have spare parts lying around this would have been a deal-breaker.Glad I didn't have to blow a bunch of fossil fuels on a return, but someone else will. Buyer beware.Regarding the 80mm, that was the first SilverStone filter I purchased and it fit exactly right. It withstood some abuse. My computer was on periodically while we were getting some drywall work done in my office space, and it did an excellent job of filtering the air intake. At the end of the project I took out the filter to clean it up. Filter was dirty but the inside of the computer case looked good as new.I bought the 120mm following a very good experience with the 80mm, so the bad fit was disappointing. A minor intervention got things working, but I just wish it would have worked exactly as it was specified. At the very least I know that the 120mm filter should do a good job of keeping the case clean.

Couldn't be happier. My case has a couple fan mounts on the side, and I wanted to deliver fresh air to my GPUs without clogging them with dust/hair. In comes Silverstone to the rescue with this magnificent piece of hardware.It needed 3 things to make me happy:1) Be easy to remove and clean.It's MAGNETIC, so it just pulls off, a quick couple spurts with an airduster, or some time under the faucet if it's really dirty and you can toss this mother back on and it goes back to being awesome.2) Needed to stop dustThis thing has a finer mesh than most pantyhose, let alone the stuff that comes with most computer cases. Every couple days I stop to marvel just how much dust this thing keeps my computer's guts safe from. If this thing was a bouncer at a classy club, that club would go out of business, because (you guessed it) nothing is getting in.3) Be cheap.Ok, so it could be cheaper, but honestly? $10 is not that bad, and it saves me from the struggle of tearing apart my computer once a month and going through seventeen million airdusters trying to clean it out. In fact, if you do the math, I'm saving myself nearly 10 cleanings a year, each one taking at least an hour, so that's ten hours saved. Let's use the valuation of my time that my crappy fast food job uses ($8.25 per hour) and what do you know, this thing will save me $82.50 a year in time, sounds like a steal at $10 now, doesn't it?Unless your case is made entirely of plastic and you keep it in an airtight, heavily filtered environment, you NEED this filter, so stop reading, scroll back up, and click "Buy," you won't regret it.
