Webman Mod & Irishman PS3

Hi i wanted to ask is it safe to install webman mod and irishman on one ps3? Will there not be clashes with each other in the future, I see that in Irishman there is also a setting to control the fan, currently I am using the Webman mod to set my fan, I'm worried there will be a clash between the two. especially on fan settings, please explain whether it is safe or not

sorry I'm still a beginner, I'm very new here

PS3 Hen 4.90 3.2.2
