Noctua NH-U12P installation...
 

WEll, I've got an i7 920 on an X58 EXTREME board ocerclocked to 3.8GHz. On Idle i get 38ºC CPU and every core about 52ºC. Of course, on idle the thing raises up to 72ºC CPU and the cores up to almost 90ºC or so. I have set the pull/push fans, but the thing thast worries me is that i have installes the heatsink 90º rotated. if the mobo is this:

I------------I
I-------cpu--I
I-------ram--I
I----------- I

I have the heatsink oriented like this so that every arrow is a fans direction:

I-----------------I
I --------> -heat->
I -----------------I
I -----------ram -I
I-----------------I

So i've read some manulas and the installation manual says it has to be vertical not horitzontal like mines. If I change it will i notice some temperature improvments?

I have installed my Noctua in horizontal position like you, with the push/pull fans to take air outside the case, I can't see why a vertical position would help to lower temperatures. However if you try it and it works, let me know
