i currently use just fans and dont really look up much on watercooling but i have heard that it is better and can have better temps but ive also heard stories about leakage and damaging parts. i mean, whats the worst that could go wrong?? i might wanna get into it

71C isn't bad at all, well within safe limits. GPUs will also throttle themselves when their getting critical temps. Highest I've ever seen one of my GPU cards was my Radeon HD 6990 when aircooled. It would run about 90-94C in Dragon's Age II, yet ran fine. I didn't like this at all, and even manual fanspeed adjustments didn't lower it much, without sounding like a jet engine spooling up at least. This is what got me back into watercooling again. After converting to watercooling, the same card, same game, temps never went over 53C.

I don't know a lot on watercooling but if you're going to do something, do it right. There are plenty of good guides out there, and asking here is a good step as well! For sure while setting up and testing if it works you want to protect your electronic components for if there's a leakage the water will drop on the components which will most likely damage them.

It can be. The newer sealed units like the NZXT Kraken or the Corsair Hydro are fine and very reliable. But they will only cool your CPU, or a video card. Not both your CPU and your video cards. The older style all in one systems are a bit pricier and unless you have a fine eye to detail can leak, which can damage your board and components.
 
Are you looking at a "kit" AIO style, or a custom loop? They both have pros and cons that only you can decide on whether it's worth it or not. Worst case scenario would be as described above, but the actual risk if done properly should be very minimal. I'd check over the many available guides to help in your decision. It can also get expensive fast, especially if going custom. I'm running a custom loop myself in my main system, and a standard AIO in another system I have. I believe there are adapters available these days to attach a standard AIO cooler to a GPU, but you have to be careful that the one you choose accommodates and cools the VRMs on the GPU.
 
using AIO water cooling for my CPU has lowered noise dramatically but runs very near to the same temps my huge air cooler did. a couple degrees cooler at idle and the same at stress levels, 26°C - 58°C. i7 4790K @ 4.6GHz. this is running on a custom "silent" fan profile. i could crank up the pump and the radiator fans and get much cooler.
also looks much nicer now than with a giant finned monster with 2x 120mm fans right in the center of my side window.

for GPUs i hear a lot of conflicting statements about the manufacturer included AIO cooling options. some people claim they get worse temps than the nice aftermarket coolers from the same manufacturers.
