its doubtful anything you use would produce the heat prime95 does anyway! the max operating temp that intel state is 66.8c,that doesnt mean you cant go higher as many do,i just think that if your under what intel state your all good. as i said mine is pretty much the same temp can get a little lower with EPU enabled but i dont bother nor do i overclock just optimal setting and mine is on 24/7 doing various things all day and night(streaming,video rendering,gaming ect) think the hottest ive noticed it at was bout 56c!
the h100 is a good bit of kit,ive played around with it turning all the fans off, after 30min my cpu only went up 2/3c.
