Replacements are $12.50 each including shipping from Sapphire and they are super easy to replace.
Isn't sapphire only selling led versions, that slightly different (0.35 vs 0.42 current, different noise floor). Only place I've found CF1015H12D selling is single lot on ali, that not available anymore, and it was $26.5 per fan. So, can you tell where are you getting such cheap replacements from sapphire directly?
The replacement black fans are available from Sapphire. Email Sapphire at
. The LED fans are for retail stores.
