while I'm not new to modding, there are a lot of areas I never wandered into. One of them is watercooling, I'm considering getting a water cooler, just to add it to my case. So my question is; I noticed on a website, when I was looking for water coolers, they were categorized by cpu type. Does it matter individually, or can I buy any cooler and can change the Block for a specific cpu type? Second question is; can anyone explain what the difference is between the different cpu types? Or can anyone direct me to a comprehensive site that I can read into it. I really want to know which one I should choose. I'm trying to put together a new machine, but my budget most definitely will not allow me to do it all at once, so I'm going to buy the simpler parts first (psu, optical drives, sata hdd's) and get the ram, mobo and cpu last. Anyone got any advice for me.
