Problem with heatsink installation

Hi All,

Back again to ask more questions. Now I'm having a problem installing a CoolerMaster Hyper N520 heatsink onto my Supermicro dual Xeon Nehalem X8RDAi-O motherboard. The Motherboard already has a backplate installed, and while the holes for the 1366 heatsink correctly fit the motherboard, they won't all screw in simultaneously. I've tried using quite a bit of force with no luck.

The Coolermaster heatsink is supposed to come with it's own backplate, but there doesn't seem to be a way to install the default one. Furthermore, the coolermaster backplate seems to go directly over some important connections on the back of the motherboard, so I don't know if that would be the best way to install the system either.

Any ideas? Thanks for your help,

Edit: So the problem involves the fact that the screws which supermicro uses are twist left to lock through the bracket, and then are supposed to have nuts which turn right in order lock them into the motherboard. It's a very odd system, and isn't compatible with already existing backplates.

So I guess the trick is either to return the heatsink, since this is a really odd design, or else remove the default backplate and add in the coolermaster backplate, which kind of scares me, because it doesn't look like it lines up well with the motherboard.

Ok, figured it out. The Coolermaster Hyper N520 simply doesn't fit with the preconfigured backplate for the Supermicro boards. So I need to find a new heatsink that allows me to screw it directly into the already existing backplate for the board (since removing the backplate would be a ton of extra work i don't want to deal with)

So I need a suggestion for a new heatsink that avoids this problem, does anybody have any ideas?

I've looked at:

But I worry that the server specification means that it will be quite loud. Also, although I won't be overclocking, I do expect to have consistent 100% loads for hours at a time.

I've also looked at the Zalman 9900, the installation looks like it will work from the flash on here:

But it's quite expensive, and also seems to be very loud for a large heatsink:

Anybody have any other suggestions?
