Or I described it in a manner that made it sound like more work than it is.
So let's take my cooler, a XIGMATEK 1283. It board mount are two trapezoidal looking brackets. The ends mount to the motherboard, the middle mounts to the HSF. The holes at the end of the brackets are long enough to accommodate the sockets it supports. Except that you couldn't take those same brackets and put them on say a Zalman or a Thermaltake something. In fact, the last time I bought a XIGMATEK cooler, I bought brackets for the wrong model, and it wouldn't fit.
And this is what I mean. So if CoolerMaster doesn't have said brackets, then you're probably out of luck unless someone out there made it. Which you could spend a few minutes on the web looking for.
You're thinking about adapting the HSF to the motherboard, I'm talking about adapting the Motherboard Retention Brackets to work with your existing HSF... IF
that HSF mounts to any standard motherboard retention bracket.
Your Xigmatek 1283 when used on an AM2 AMD motherboard mounts directly to the original AM2 motherboard retention brackets
. Meaning, you can take your Xigmatek 1283 and any retail AM2 motherboard & with the Xigmatek AM2 kit on the Heat Sink mount it to that AM2 motherboard without doing anything to the motherboard. It simply clips to the retention brackets as AMD intended. Meaning that if you had the hardware necessary to mount your Xigmatek 1283 to an AM2 socket, all you would need to mount it to say an FM1 motherboard would be an FM1 to AM2 Retention Bracket Adapter. Likewise, if you wanted to use that Xigmatek 1283 on an LGA1155 motherboard & you only had the Heatsink hardware for an AM2 socket, then you could get LGA1155 to AM2 retention bracket adapters.
Now in a case where you originally had to change out the stock motherboard retention bracket, then yes there would be a more involved process, and you would need additional hardware from your HSF manufacturer.
BTW, I've been searching since I first put my Llano APU into FAH production several weeks ago, but I know that not everything is on the internet...
