M3 Magnetic Screw Set, Suitable for Fixing 25mm Thickness Cooling Fan on The Surface of Various Electronic Products (10 Pack)

When it comes to mounting fans these are my new favorite screws. They fit snug in most fans and they and can be easily placed anywhere your case is metal. Love being able to just pick back up a fan or slide it over if I make an error and need the space or to tidying up cords I forgot instead of having to unscrew them. Great for those beginners building a PC for the first time. Just keep in mind the magnets do sit over the side of the fan so they won't sit flush so, but that does give you a cheeky little nook for you to slide the cables under instead of around. Their quality is ok, the magnets are strong but they will pop out of the feet if you screw try to tighten them to much because the hole for the feet goes right through to the feet and to the other side. I just used some super glue and popped them back into the door and everything was good to go. The overall ease they have added to working on PCs is tremendous, and you can use them for just about anything. I've used a few for hanging up picture frames, lights, and other projects I've done around my house.

The magnets included with these are strong enough to get whatever job done you're needing for a pc fan. I bought thise to use with a 30mm fan and while the screw was long enough, the diameter of the magnet end that the screw goes into was just too wide for me to use for a 30mm fan. I could have drilled out the screw holes for the fans and inserted the magnet/screw receptacle that way but I didn't want to damage the fan. I imgagine these are meant to be used with a bit of a gap inbetween the magnet end and fan but I want to reduce that as much as possible. Fantastic product, though.

Works great added back fans to the z15 miner. Excellent mod option.

Pretty good magnet. Perfect for small PC projects like reorganizing the fans.

I got these to easily add fans inside my SAMA fish tank case. These mounts let me easily add fans to the bottom of the motherboard area of the case. The magnets were very strong and allowed flexible and optimal placement of the two DarkRock LED fans I also purchased. I do recommend that you make sure that the bolt isn't too long if you are using this to install a thin fan. You might have to use a shorter bolt or cut it. I think the only way these could be better is if they came in both white and black color options.
