I first bought these to cool my cryptocurrency mining rig which gets insanely hot and requires fans of all sizes and cooling. Air escapes sideways. Spend a little more and get something that will really cool your rig. Don't expect anything from them, you won't feel wind with your hand right in front of them. For me it was a waste of time and money. Please, I beg you, stop giving these people any more money. They robbed me and many other people. The only positive is that they give off a very bright blue light. Unfortunately, the blue light does not improve the airflow of the fans. At the risk of sounding redundant, I definitely wouldn't recommend this to anyone except maybe your worst enemy. Even your worst enemy doesn't deserve fans that don't blow air.
