Temps seem pretty good, about what I was expecting. I've only really been over clocking the GPU for now will go for the processor tonight probably.
At stock the GPU idles around 10 or 15 degrees above ambient, full load after the liquid has had time to warm up it's around 23 above ambient, normally my room is about 20ish degrees so real temp anywhere from 44 to 47 degrees.
Overclocked with +100mv it jumps to 50 - 54, pushing it to 200mv it goes to 60.
CPU at stock idles about 7 degrees above ambient and on a real game load only gets 15 or so above ambient.
I am pondering whether to add another 240 rad and another 290. But at the moment the overclocked 290 is more than enough for 1080p. Maybe ill treat myself at Christmas and get a new monitor to justify the extra card.
