Yes it fits! I have one in push pull configuration on a gigabyte z68x-ud3h-b3 with no type of problem to install! I had a sabertooth x58 that made the installation a little bit hard because the 8 pin power conector it´s on a horizontal form on the top left of the mobo and i had to conect first the 8 pin cable to be able to install the h100! It made a little presure on the cable but nothing to worry about!
