I was putting the heatsink, XIGMATEK HDT-S963 92mm Rifle CPU Cooler, onto the cpu, AMD Athlon 64 X2 7750 Kuma 2.7GHz, in my new build. Also my first full build, I've done some upgrades but never the whole deal. Anyway the heatsink doesn't completely cover the cpu like I've seen before, is this a problem? It is only about a mm short but I still noticed it, will that cause the cpu to overheat.
P.S. I used thermal compound from best buy and it's 99% silver if that matters.
You should be fine. They leave it short so you can see the excess squeeze out and focus directly above the core.
Silver paste conducts a current and can short out a mother board. So only use a BB side bead. If its squeezing out alot make sure none runs onto the board.
Also a CPU is really the size of your pinky fingernail. The silver mating surface is nothing more then a sealed cap. You can see how big it really is if you do some research.
Also always check your temps. After you get a board going you can view the temps in BIOS under the health category.
To put your mind at ease read this. Remember what I said about the size of a fingernail.

This is not your average aluminum heatsink with copper heatpipes, but it looks innocent enough from the outside. The Xigmatek HDT-S963 heatsink is a unique thermal solution because the German thermal engineers who designed it, made its three copper heatpipes come in direct contact with the CPU itself.
If you take the Xigmatek HDT-S963 in hand and flip it over, you'll see an aluminum base with three long grooves cut into it. Set snugly in these grooves are three copper strips which are the heat pipes. There is no bulky copper base plate, no heavy copper heat spreader, instead heat is conducted directly from the core of an AMD or Intel processor to three 6mm diameter copper heatpipes. The heatpipes in turn transfer that heat directly to a large aluminum fin cooling tower above.
