The Rubber Anti-Vibration Screws not only mount your case fan - they dampen the vibration between the case (or other mounting surface) and the fan. This results in up to a seven decibel decrease in perceivable noise of a mounted fan.

Each package contains four fan vibration isolators which are compatible with standard fan screw holes and fans with closed corners. The standard fan screw hole size is 7/32" (5.5 mm). Please double check your fan and case for compatibility before purchasing.

These fan mounts work with our 80mm, 92mm , and 120mm case fans. They don't work with 60mm case fans since 60mm fans have a smaller hole than the 7/32" standard fan screw hole.

• Prevents resonance, absorbs vibrations that otherwise would be transmitted from the fan into the computer case.
• To be used on closed chassis fans
• 4 units to be used per fan
• Extremely high quality parts with very supple rubber used
• Far superior to similar products on the market

These are the worst rubber screws I''ve come across. They are simply FAR too stiff. It is EXTREMELY easy to pull too hard on these and break them - they are so stiff they would rather stay half-way through and snap off the end that you''re pulling from. I''ve gotten rubber screws included with fans that were better than these. Just pass and try another set.

"Head" part that supposed to stay on mounting surface won''t stay because the diameter is too small. Fan just pops right off. Ate the 20% restocking fee for this one.

Looking at some of the reviews, I was worried these wouldn''t work much or at all. They''re only a few bucks so I figured there isn''t much to lose. I put them in my computer this morning and yes, they work, very well. I have a CM-690II Advanced and I put these on both of the stock exhaust fans (because they''re both close chassis fans). The difference in vibration noise is huge. I mean, it''s absolute. Before, on full speed, the fans would use the entire case as a diaphragm; it would turn the vibrations directly into a loud ''brrr'' noise. Now there is, quite literally, no vibrational noise at all. I can turn the rear 120mm fan or the top 140mm fan to 100% and only hear the sound of air moving. Some things I''d like to point out: 1) Your fingers will probably hurt after installing these because you have to hold them tight to pull them through the fan. 2) These will stretch, a lot. You will only manage to break them if you are a gorilla.

I just ordered these a 2nd time to replace some I broke. Handling a little too roughly I guess. Anyway, the ones I received the 2nd time were not the same and would not hold a standard 120mm fan, the rubber ''bead'' just keeps slipping back into the fan screw hole. I think these things are a great idea, but Im looking for a better product...

over 10 broke out of 20. They lasted about 5 months. the attached grill on one broke a fan blade on a neighboring fan. Is it just dry weather in California? not sure. none were exposed to direct sunlight nor were any ever in temps higher than 90F. maybe try some rubber shims?
