If its clear in a few weeks then you wont need to. Just make shure your ferment temps are within the yeast range and doesnt drop out before its done fermenting within the first week. Cold crashing is more ideal for dryhopping for me personally, either way if its going to clear then its going to clear in the bottle with conditoning and lagering/refrigerating without cold crashing it anyway. If Im fermenting in cool temps I like to raise the temps some near the end to enshure fermentation is complete, if cloudyness is an issue then I may cold crash it but I normally dont but I do often if Im kegging. Alot of times the beer could be hazy anyway according to some recipes and malts or even alot of hops. That said, nothing would hurt to do a few weeks or more bottle-conditoning in the fridge after room temp bottle carbonating/conditioning.
