before i'm on watercooling..i'm using xigmatek achillies to cool down my i7 965 at 4.0g's..

idle temp is at 5x and load temp is almost 95..that would not be so good in my opinion, however

if you need something which is more better than xiggy, try prolimatech or venemous-x..both would show you good result...but oc'ing on air is quite riksy...

i've been using h50 but not h70..

h50 performance is quite similar with prolimatech megahalems bro..but that time, i was using QX9650..the temp is quite same for both cooler..+/-1 only..

is okay if you are going 4.0g's with h50, there is no issue about that, but once you oc, you have to monitor the temp, you have to remember that i7 965 is c0 stepping..

it requires a more voltage that an ordinary i7 procs, which means that it is more hotter..etc, 920 d0, 930, 940, 950..
