Understanding options for Socket 775 heatsink/fan mounting

Hi all -

I have a Gigabyte MB GA-P35C-DS3R
and an Intel quadcore CPU, with an Intel heatsink and fan.

I'm having trouble getting the heatsink push-pins to go down and _stay_ latched down.

No matter what I do, when I get the third or fourth pushpin down,
the board is very slightly bent!!
That doesn't seem right, and the HS/fan will pop out with the slightest tug.

The processor IS seated correctly and snapped in correctly.
I do have enough mechanical aptitude, after 30 years in amateur radio and other engineering fields
to know when something is likely assembled correctly.

Also, when three of the pins were attached and the fourth one mostly so,
I tested the system briefly, and it booted up absolutely normally to the BIOS screen and stopped at the no boot device screen. So the processor couldn't be mis-installed if it will boot!

I have tried this with the Intel heatsink/fan, a no-name very similar heatsink/fan, and
now a BestBuy Rocketfish HS/fan.

To my disgust, the Rocketfish ended up having the same push pin type connections (in spite of the BlueDude telling me it mounted otherwise - I think he was talking about the AMD mounts)

Do _all_ Socket 775 HS/fans use the dratted push-pin system?

I was really hopeful that the Rocketfish HS/fan would use a clip mount as I've used for
years on AMD processors and earlier Intels.

I don't want to buy some monster watercooled $100 heatsink system, I'm not planning on overclocking the processor until you could use it in the reactor control system on a Los Angeles attack sub's nuclear systems!

All I need is a basic heatsink suitable for running the processor at normal settings, or maybe slightly pushed down the road.

I am now glad I didn't buy something off TigerDirect or someplace, because it appears I could easily have gotten another HS/fan with the pushpins, in spite of what some salesdweeb promised over the phone...

Recommendations and advice for this newbie to the new style heatsinks on quadcores ??

thanks, Rabin
