AIO Cooler sitting very close to RAM, how concerning is this?

So after putting together my first build, I realised that I should probably have gone for a larger case. I was set on a top mounted AIO cooler and went for a Corsair iCUE H100i ELITE CAPELLIX cooler as the case (Corsair Carbide 275R) advertised this to be compatible. What I did not realise is when mounting the radiator and fans on the top section, that it is impossible to sit center where the screw holes are. I have had to push it against the side and use the case mesh for screw holes and only screw one side of this, see picture. It seems fairly secure however my concern is it will eventually fail and push against the memory (Corsair Dominator Platinum RGB 5200Mhz DDRR5). There is currently about a 2mm gap between the fans and the cooler, and I understand that fans will move to a degree when in use. My question is, how long can I get away with this before I eventually upgrade my case?

It looks super close from this angle.

Only 3 screws holding on one side through case mesh holes.
