This is the bulk version so there are no screws included!
These fans are great (move a lot of air + silent) and when connected correctly as argb the blades look fantastic.
Bought 2 of these for me new H500M case to place them on the top of the case for exhaust and machy-machyness. They actually work really well. Shipping could have been cheaper though..
I bought some ARGB splitter cables to connect to the pre-installed H500M ARGB controller. Right now, I have 4x 200mm CM ARGB and 1x 140mm CM ARGB fan connected to the controller - a total of 5 fans. Then the lightning effects are controller by my motherboard.
The only issue I found was that these spare fans did not spin as fast as the ones that came with the case pre-installed. Even though, Coolermaster claims that the fans sold on this page are the exact same ones used in H500M, something is a bit different as the fans spinned below 800RPM at 12V DC, while the ones pre-installed ones spinned around 830RPM or something at 12V DC, or in some cases around 70RPM faster.
Well these are completely useless since they decided it would be better to send no screws with it.
