?s about upgrading CPU heatsink (pacifically, socket 775)

As a hardware noobie constantly trying to accumulate knowledge, I have question,..

I was thinking about upgrading from the stock CPU heatsink on 775 mobo. I know that most modern heatsinks require a brace/baseplate to be put behind the socket for the heatsink to screw in. Because all 775 heatsinks use the same screw positioning/size, couldn't I just use the stock Intel brace and just swap out the heatsink?

Don't recall a backplate being a stock item on an

Intel MB or on an Intel HS FAN

Here's a Intel MB ... no HS Fan backplate there and there's no accessory part either.

Only time I see a backplate is on a MB with an oversized aftermarket HS Fan.

Ohhh... urrrrm...

I'm talking about the heatsink you get when you buy the CPU, not the mobo.

I should probably explain myself better.

Look at this picture set that comes with the Thermaltake CL-P0464.

As you see, it comes with a mounting bracket that is placed behind the motherboard. It seems (somewhat) logical that should I install a heatsink like this, I could just screw it into the bracket that is presumably holding my stock intel HS in place.

NONE of the many AMD or Intel CPUs I've purchased over the

last 20 plus years came with backplates and I should add they were all retail CPUs with HS fans. The backplates I've acquired over the years always came with high-efficiency, aftermarket heatsink fans.

urghh.....

So I just cracked open my case and got a look at the heatsink. The heatsink is screwed in through the 4 holes on each side of the 775 socket. Could the holes be threaded, or is there a brace behind there?
