So I want to buy a new AIO liquid cooler for my reference design asus r9 290. I'll be doing what linus did in this video: https://www.youtube.com/watch?v=LM3DyUqWWns and that's basically to zip tie the pump to the gpu. Now I need the AIO to have a single 120mm radiator because that's the biggest one I can put on the back of my case, it's silent base 800 and I don't think AIO's have long enough tubes to put the radiator on the top of my case so that's why I need it to be 120mm. Now I know that vrm gets extremely hot...that's why I don't want to buy kraken g10 and what I wanted to do is buy 16 of these: http://www.kupujemprodajem.com/Hladnjaci-za-graficku-karticu-i-ram-25058701-oglas.htm?filter_id=46032929 they're basically metal coolers that I can put on vrm. I'll take one more fan that's about 120mm and put it so that it blows on the other parts of the gpu(the right side of the gpu because left side is covered). Now what I need you to tell me is, are there any other ways to cool this gpu and vrm so the temperature of the vrm doesn't go above 70 degrees(the lower the better). I also need you to recommend me some AIO cooler.
