Some of them say 52mm and some 56mm is there a big difference in cooling ?

the difference of half an inch can make quite a bit diff so my miss reckons, its the difference between a oh and a agh, so yer mate it should. proberly not temp but more cooling capacity if you should need it.

4mm isn't even half a centimetere let alone half an inch wouldn't think it would make much diffrence .
