mob fans and conveyors (about 2 stacks worth) taking up ram on server

[TearinGaming786]

on my smp which runs better mc and a few other mish mash mods for me and a few friends, i noticed a sudden boom in the smp ram usage, with id say around 64 total fans running on the smp, the ram usage went from 2,000 mb to 11,000 mb and persisted until the chunk was unloaded or fans turned off. not sure if this just wasn't designed with servers in mind or if this is an actual issue and figured i should report it just in case. i've switched over to conveyors now and altho it does boost the ram up it only does it by abt 600 so im not as concerned. happy to present any information i can! this is for version 1.20.1-1.0.3 of the mod running with better minecraft and 16 other mods. i also narroed it down to extreme tick delay of a maximum of around 130 tick delays, with only 6 players logged in at the time.
