Water cooling loops are not that hard to do. I started five years ago, and made the investment into a custom loop. I got my parts from places like danger den, frozencpu.com(btw...don't order from them anymore, they have gone bust and the owner is a complete junkie, took 3 months to get my money back on my upgrades to my new build I did back Feb. 12th from my card company.) Newegg....back when they had water cooling parts other then AIO's. Danger den is a good source, and never let me down....there are some other sites. I have always gone with 3/4" lines, tripple rad min, make sure you stick with similar metals, Copper rad, fittings...etc... some metals don't mix and will cause issues with your loop gunking up. I have tried the higher dollar non conductive fluids.... they are ok and I got almost 4 years out of them. I am running distilled water now, and a silver strip... and all clear so far.
I invested around $350 into my loop 5 years ago, and just spent around $120 in upgrades back in Feb. and only the new 3/4" lines was really needed and the new water tank because of my custom wall mount case. I really didn't need a new water block, or fittings, I just bought them to make my rig look better. I have found if you take the plunge and get quality parts from the start, a good pump, rad, and cpu block, it is a investment that can be carried over to all your new builds for years to come. Do it right the first time, try not to skimp on the pump and the rad, cpu block, and you will be happy you made the investment. One important thing is to make sure you have the placement right on the rad and the pump, make sure when you fire it up for the first time to not let the pump burn up from lack of water. Use another PSU to fire up only the pump, do not connect your mother board or other components up in case you have a leak... and turn off the pump by unplugging it if you hear air in it, make sure its getting water, then turn it back on. Leak test for 24 hours if you can using this method. Very simple procedure, youtube is your friend.
I know I have, I am on idle and at 26C on my I7 4790K @ 4.8ghz right now... never see higher then 49-51C while gaming. I have set up good air flow cases, and to be honest, its just not the same as a well built quality water loop. I have never bought a AIO water loop, and don't think I ever will. Its just to easy to put together a custom loop, and the results have always been better from my experiences.
