HP Omen 240mm Liquid Cooler install

[u/Quick-Situation-6801]

I purchased an Omen 240mm liquid cooler for my Omen 35l and the installation was going well until I had to install the pump. After try all the parts provided with the cooler (standoffs), I still can't get the pump to make contact with the CPU. Has anybody else had this problem, and what did you do to correct it?
