Metal backplate touches solder joints from CPU.

Thread Starter 
I'm installing a silverstone NT07-AM2 heatsink on a Zotac Geforce 6100-ITX motherboard. I removed the old AMD mounting bracket and back-plate and proceeded to install the new heatsink when I noticed the silverstone back-plate square opening wasn't very large. When I placed it against the back of the motherboard I could see the solder joints from underneath the CPU socket touching the silverstone back-plate. The back-plate is made of metal and has a thing layer of some sort of rubber on one side (the side touching the motherboard). But the solder joints stick out far enough to where they pass the rubber layer and may possibly touch the metal back-plate. Not trying to short my motherboard but I want to make sure there isn't something stupid I'm missing.

Pictures below show the back of the cpu socket on the motherboard and also show the silverstone back-plate for the heatsink. Any advise is appreciated. Thank you.
EDIT: Added new picture at top that better shows how some of the metal on the back-plate is exposed.
EDIT2: Added post #6. Received official word from Cooler Master that my AM2 socket is not compatible with these types of backplates (tested gemenii M4 cooler)

If there aren't visible punctures in the rubber I wouldn't worry about it.
-edit-
I see what you're talking about. It shouldn't be a problem, but if you're really worried about it wrap some electrical tape around the edges of the opening.

Thanks, think I will to play it safe. I tried getting close enough to see if anything made contact but it was hard to tell. And I'm sure after some slight pressure from the installation the joints would possibly be even closer to the metal.

Time to cut some thin strips of electrical tape.

or you could get some stock rubber/rubber with adhesive on one side and make a thick backing for the backplate.

i believe i have some 1/4 inch rubber with adhesive on one side, if you want me to ship you a small piece of it.

That's a good idea too. I think I'll stick with electrical tape for now. But thanks for the tip.

Edit: I went ahead and installed without any electrical tape. I wanted to see for myself. I wasn't able to get a clear shot with the camera but I inspected it and doesn't look like any of the solder joints are going paste the rubber/plastic layer. We'll see what happens what I turn it on.

Edit: was able to grab one pic that kind of shows it. Okay I'm done now =). Thanks all for helping me ease my nerves.

Regular shot

Just wanted to update this thread in case it helps anyone in the near future. I received another cooler to use that had the same issue with a simliar backplate. The Cooler master geminii M4. I shot cooler master an email about the situation just to get their opinion. After a week of waiting and a few more back and forth emails the answer was simply that my AM2 socket is not compatible according to Cooler Master. Cooler master said that the lay out of my solder joints is not standard and that the cooler is not compatible. Their solution, to get a compatible one. I sent them one last message telling them I liked the M4 and wanted to know if I could install it without the backplate if I bought some additional rubber washers for the nuts. Still haven't heard back from them but I went ahead with the washer idea and everything seems solid. The board is horizontal which I think helps in this case (no pun intended).

In all honestly if i was building it, i wouldn't even think twice about it and i'd mount that puppy on there. The back plate was designed for situations like this.

According to cooler master the back plate provided with both coolers was not designed for the type of solder joint layout I have. You might not be able to tell from the pictures but the solder points overall surface area is larger then the square cut out on the provided back plate. So there's a good junk of solder points making contact with the back plate.
