Hello,

When you use some finger gards on the fan, the fan will have enough cooling and will be safe to use.

This is only one example, but you can get them for all sizes of fans.

@bertus Thank you for the link. I was planning on ordering one since I lost the original one. Its a custom made case with all the components and I had tried all the pc fan finger guards I had but none would match.
