I have a corsair 750D and the dust filter under the PSU intake vibrates and makes an incredibly annoying and loud buzzing/vibrating noise. I solved the problem by using electrcial tape on the outside of the case to stop the filter from moving. What I'm wondering is, the back area where I used the tape gets pretty hot because of the PSU, is it safe to use electrical tape their? Since I'm worried it will melt and seep into the case.
Using electrical tape to stop dust filter vibration?

i agree with Blackbird,
Might i also suggest using sticky weather strip molding they use for screen doors available at home improvement stores like home depot or lowes and us it on the edges of the dust filter which i feel is a more elegant solution?

well, apprently taping it did not solve the problem, but continously pushing it inwards does and so does removing it. Do you know if its really nessecary that I keep the dust filter inserted? Since right now its making a huge racket and Im not sure if its worth the hassel.

Sticky back Velcro.
All the way around.
Keeps a good air seal, and isolates any vibration. That is what I used to mount a bottom filter on my 540 AIR, that Corsair (grumblegrumble) did not see fit to actually include over the big hole in the bottom.

You know about 90 percent of computers do not have a dust filter on the PSU.
I have never seen a OEM like Dell or HP use one (I work for HP)
your fine without it for now
the sticky back velcro like USAFRet suggested or stick back weather strip molding like I suggested would fix it

Is the PSU or the frame holding the filter vibrating as much as the filter? Or is the filter just vibrating so severely because of a resonance? If it's a resonance, you can just tape/glue some weight to the filter to change its resonance frequency. It doesn't take much.
Way back when the DC-10 and L-1011 were being designed, because the third engine on both planes was mounted in the tail, both manufacturers ran into the same design problem. Small vibrations in the engine and the flexibility of the tail sets up a resonance, causing a pounding noise and sensation. The Douglas Aircraft engineers took the brute force approach and lined the entire ceiling of the passenger compartment beneath the tail with lead to reduce the noise. If you've ever ridden in the rear of a DC-10 (or MD-11), you can still feel the vibration at certain engine RPMs. (The noise sounds like when you stuck a baseball card in the spokes of your bike wheel as a kid.)
Lockheed's engineers went through the trouble to figure out exactly what was resonating, and changed its spring/mass/damper characteristics to eliminate the resonance.

The Douglas approach is what you're taking by trying to tape the filter in place or wedge something in there so it can't vibrate. They won't really help since even a small residual vibration at the same frequency will eventually lead to the filter vibrating almost as strongly, because that's what resonance does. You have to change either the frequency of the vibration, or the frequency the filter wants to vibrate at.
