Questions about getting water cooling

[Hollow021]

Me and my friend both have almost the same cpu (I have a fx 6100 and he has a fx 6300), but he has water cooling on his and he doesn't do massive games on it. I got a stock fan taht came with my cpu and it's not running that great and also I want to overclock my cpu because it's lagging on some games. So I asked him if we could replace both of our cpu and coolers and he accepted. Now before I do it, I wanted to know how often will I have to change the liquid and all, and how much the liquid costs? And is it worth it?

water cooling's never worth it its just to much of a hassle get a cooler master 212 evo and be done with it

It sounds like your friend has an AIO loop such as the H100i. If this is true then you don't need to replace the fluid.

I don't know much about liquid coolers so what's that? I mean it kinda looks like it, but the radiator is smaller.

In that case he has a H80i. If it doesn't have a light in the middle it is probably a H80.

So what's the benefit of that? Just not having to replace the liquid? And does the liquid go bad eventually?

There are a lot of places that have discussed this countless times all over the web. I suggest look up "benefits of AIO coolers".
