Gaffer's tape to the rescue! Two issues with this configuration thoughStory of my life. Day late and dollar short as Americans say.
Indeed, not an easy install. Is this your Meshify 2 case?
Trying to think of a way to cheat and make it easier. Like maybe a little double stick tape to hold fans in place on radiator? Or maybe tape fans to rad on sides until screws are installed, then remove it?
1. To clean on the fan impeller side, I have clean them in-place from the other side. Than looks painful with these curved blades.
2. My temperatures are slightly warmer now. the pull config did better.
Might go back.
EDIT: Another thought: Pull with a shroud on the case side of the radiator (not your typical use of a shroud)!
temps see better at high rpm and a little worse at low. Is this the fan motor heat?
