Often we would like to attach our fans so that their vibrations are not transmitted to our cases. While we could use "rubber screws" a.k.a. "vibration isolators" (the best of which is
here), sometimes a fan must go in a closed space. Or we have a 140mm fan with 120mm screw holes, and it must go where there are only 140mm screw holes. Or we have a 140mm fan that we want to use in a 120mm window, and our only 140mm fan has 140mm screw holes. Or we want to use a 200mm fan and the screw holes do not match the ones on our case. The answer is Velcro.
In particular, we need Velcro squares.
Now, you could cut squares from Velcro strips, or you could just buy Velcro squares:
When you pull them out, they look like this (sorry about the fuzzy image):
Cut them into strips:
Then slap them together and cut the paper to separate the squares:
Now take your razor blade and cut the squares diagonally, to make nice Velcro sandwiches:
Pull off one side. Make sure it is the same side. I decided that I wanted to put the fuzzy bits on the fan, so I pulled off the paper on the fuzzy side of the half-sandwiches:
Stick them on the corners of a fan:
Now pull off the paper from the other sides of the half-sandwiches:
Ooh. The fan is ready to stick on something:
Slap it on:
Done!
And now you can pull it off:
Here's a closeup - fuzz on the fan, loops on the mounting surface:
And that is how you can use Velcro to mount a fan on something. I'm sure all sorts of wonderful ideas will spring into your fertile imaginations.
