Safe to run computer without heat sink secured?

I'm in the final stages of putting my new pic together that I built.

I just came to realize that the motherboard and my cpu heat sink won't work together. The heat sink is from my dell Inspiron and bolts to the motherboard. The new MSI motherboard isn't threaded there, it's meant to be used with plastic clips.

I don't want to wait til Monday to find out if everything works, so what I plan to do is leave the tower on its side, put the thermal paste down plug the heat sink fan in and rest the heat sink on top, so the weight of the heat sink wil press it together and the paste will bridge any gaps. If the whole tower is on its side the heat sink will stay in place and do its job long enough for me to install Windows and verify it all works.

Is my logic sound or am I going to destroy something?
 
Alright guys, you convinced me not to try it.

I have to wait until Tuesday though, I've been down for a week now!

It's crazy how you can't get any of this stuff in person anymore, I looked for 50 miles around and no store has cpu fans and heat sinks in stock. Best Buy has one option with a full liquid radiator for like $150 but I'll pass on that.

Thanks, everyone.
 
I have Amazon prime so cost isn't an issue, just wait time. At that point even the next day option was 3 days because of the weekend.

It was up and running Sunday, though. I figured a solution to it without waiting until Tuesday.

Sunday afternoon I took a trip to lowes and got some 5mm x 3" bolts with matching nuts, along with some rubber washers. My plan was to run the bolts down through the heat sink mounts where the factory bolts would go, through the holes on the motherboard and out the back. Then put the rubber washers on the end so the nut doesn't contact the board and tighten down the nut, boom.

The bolts were a bit too short though, so that's where I got the dremel out. I shaved about a quarter inch of metal off of each mount so the bolt could drop that much further down, it came out perfect.

Slapped the paste on, bolted it down snug, fired it up. It idles at a cool 29-30, and gets up to 50 at the max when I run dying light or just cause 3 at ultra high settings
