Coolerguys Anti-Vibration Gaskets (120mm)

It works and it does what it's supposed to, can't ask for more. I guess you can DIY instead and come up with a similar solution, but these are cheap enough. I still have a few similar gaskets for 120mm fans from the days I used to water cool and those seem a bit better and easier to handle, in that they have skirting around edges that "hug" the fan frame so it stays in place during installation. These don't and it can be a bit of a pain to install depending on where you are using them. They do appear to be a bit flimsy, so I would take some care with handling them so that you don't accidentally rip them apart. The mounting holes are a bit small, but perfect for 6/32 machine screws; I would not try to use regular case fan screws as you may start biting into the material possible ripping them apart at the edges.

I ordered these because my radiator fans had a slight bit of gap after being tightened as tight as they could go. To avoid the unnecessary vibrations that would've caused, I ordered these gaskets. I got the 120mm gaskets, and they seem like they'd be for a 125mm with how much extra slack the sides had. (I know that's not a PC fan type, I'm just saying that there's extra slack). I cut off the sides, and only used the corners, and they work just fine that way. But if that's the case, you'd likely be better off buying rubber screw washers, or something like that.

I bought these recently to solve a vibrating fan issue (The fan spinning would cause the back of the case to vibrate against the I/O shield and thusly would make this buzzing/annoying vibrating sound) after taking a look over things... Example - Looking over the back plate and making sure it was tight, checking the fan for any obstructions, and checking the fan it'self and oiling said fan with 3 in 1 oil I decided to buy these rubber gaskets (After some research online of course) and I can say I'm 100% satisfied with the outcome, they're easy to install and easily silence any noise if you're having the same issue that is (But I suggest checking things over first naturally) the quality of the gaskets is decent...I mean they're just over 5 dollars in price so don't expect "too" much there BUT the point is they get the job done, that said I 100% recommend this product.9.5/10

Measured 70mm across. Very little help when I contacted the cooler guys, but told me to take it up with Amazon. Amazon said it was likely I would have the same issue if I returned it for the same item. Ridiculous.

I should have bought one more (I have bought two of these so far). I have a 120mm Delta fan slapped right on to my Prolimatech Megahalem CPU heatsink. That heatsink was designed for slimmer 120mm fans, so I have been forced to use zip ties to mount my Delta fan to the heatsink. As a result, the vibration is loud and incredibly annoying. Don't get me wrong, I am all for super high CFM fans and can tolerate the noise that comes from that, BUT VIBRATIONS AGAINST METAL? *we're all going to die*If YOU have this problem too, this is a must have! I also highly recommend getting some of that high density foam tape if you're using zip ties like me. You can use strips or squares, use a flathead screwdriver bit to punch through, and then push your zip tie through the high density foam. If you use the high density foam wisely where needed along with these 120mm anti-vibration rubber fan gaskets, you'll definitely get rid of metal vibration noises. ONE OF THESE GASKETS MAY NOT BE ENOUGH, ORDER AN EXTRA JUST IN CASE.

I’ll admit, I’m a little conflicted that, in the same order, I received gaskets with two different materials (three 2-packs of silicone rubber and one 2-pack of latex rubber).While I’m happy with three of the packs, the fourth pack is concerning as the rubber has different chemical, thermal, and mechanical properties less suitable (not to mention the poor finish quality and odor) for purpose. The lack of product consistency makes this difficult to recommend or even consider for certain projects where a more flexible material material less sensitive to hot or cold temperatures, UV resistance, odor, or chemical stability (exposure to air) is required.

When installing the Noctua 3000 RPM model fans, we always utilize these bushings. They really help keep the vibrations (not that much in a good fan like Noctua) separated from the chassis. When you are buying really good fans, you want to make sure that all of their air is going where you point it (and not leaking due to air spaces). This provides a means of sealing that gap between fan housing and case. Well worth it when you are putting the money into quality fans (or even cheap ones for that matter - b/c they would shake more than a well balanced one). IF you have noise coming from your fans, this is a great solution.

They Fit well, item just as described.
