Help! Can't install the heatsink. Pics included.

Hi

First of all I am a newbie on hardware stuff.

I just upgraded my CPU and bought a new cooler. Uninstalled the stock cooler took me about 45 minutes.

I have an old Socket 939 motherboard. It has no retention module. I did some research but I am still not sure what I need exactly.
The old cooler had 4 push pins so didn't need it a retention module.

Something like this:

Without the retention module right now my cooler is sliding around and I don't think this is gonna work in the long run.

Okay so here is the situation right now:

Got the new cpu working perfectly. I just put the cooler on top, for now it seems to be working but I cant put my case vertically or it slides. and it just feels unsafe.

Do I need some kind of a adapter/converter to install retention module, do I just need a retention module, What do I need to get this working right?

or did I just bought something incompatible with my motherboard!!!

Here are the pictures:

THE NEW COOLER: (Arctic Cooling Alpine 64)

The Mother Board:

I have looked at these before, all of them have two holes side by side. I don't think it will fit my motherboard. (It has 4 holes like in the pic). I am guessing there just isn't any retention bracket for this.

I am planning on buying this:

4 Push pins.

My Motherboard model is NF-CK804.
