i got mine up to 170 very stable with an s7 fan on it. i can take it up to approx 180, but thats too risky i think, i heard someone talking about running it at 195 or so, he had one of the latest, they are better oc able.
try it and you know it how high you can go start at 160, 165, 170, 175, 177,179,181,183 and so on after trying the new speed use it for several hours to see if its stable, if it ahngs or if you get black markings your going to far, without any extra cooling like a s7 fan i think you wont be able to get more than 166 stable. dont push it too far.
All I used was 4 no.6 wood screws cut to length. I placed a little nail polish(my wifes by the way!!) on the screw heads were they come in contact with the heat sink. This is probably overkill, but the thought of a screw laying across my soundcard doesn't impress me.
I just had an idea. I'll put a little piece of styrofoam on the heatsink where the screw will align so that the screw can be screwed (???). Styrofoam does not melt when it's heated in the heat sink, right?
i used only 1 screw to attach it to the heatsink cause the fan is too big. only 1 screw will hold it, thats good enough. we all try to find or own solutions, so attach it the way you think, but the 1 screw doesnt cost any time the other options do.
I may be white trash but I attached an 80mm fan to my voodoo3 2000 with a rubberband and it is stable at 175. Just a thought. Now I am gonna go back and watch the bug zapper, on the front porch of my trailer, in my underwear. Later
Finally got the 600e and the Global win VOS32. Now I need some good ram...
