But the whole point of this argument is that if you cheat then you probably don ' t know what you ' re doing . <| sep |> The problem with Nano is that the stock cooler is rather bad and the GPU thermal throttles . And the fan can get really loud . My idle is just under 40 C . I can ' t be bothered to check what it gets under loadsince I would have to wait until the water heats up but if I remember correctly something around 65 C , maybe . I have 240 mm rad with older Noctua fans . So that cools decently well . One of the main reasons I did it in the first place was that I got the rad for free from work . It was part of all in one where the CPU block had melteddumb story why we had it in the first place . The other was that Nano GPU block was actually rather well priced . I would not get any other GPU block under 100 but that one was 80 . I don ' t think water cooling would be something for you if you want extra performance . Maybe if you want to reduce noise but you still have fans and a pump that still make some noise . But overall it was fun to build water cooling . Made some mistakes and what not . If you have the money to spend it ' s a pretty cool addition to the PC building hobby .
