So i got my motherboard to work,grubbed my I7 920! dropped a bit of heat sink compound!,grubbed a paper and applied,mended so that the Thermal paste has a nice spread across the cpu!,Grubbed my Horrid Heat sink and settled it,locked it in in place!

Booted up,Ran Core temp and boom ! am hitting 100 Degrees Celsius on my CPU,

can anybody help me out ?,my suspicion is that there is a pocket of air between my CPU cage and the heat sink but i do not know how to check and make sure it is air tight

I am on the dx58So board with a intel i7 920 at stock speeds

Honestly even though method and amount has an affect on temps, there's more at work here than the way you spread the thermal paste.

Even on the stock cooler, it shouldn't be reaching those temps, I don't think it would even go that high if you bought two tubes of AS5 and squidged the whole of both onto the CPU, you'd just get a whole ball load of excess around the socket.
Thermal compound just bridges the microscopic gap between the metal on the CPU and metal on the heatsink. A good paste with a fair amount of conductivity is pretty much all that is needed. Application methods and brand are really considerably over examined imo.
With that said I like the dot method (eh, figured I'd add to the method conversation).

I'd...

Are you talking about Linux (GRUB) or CPUs? But, seriously, you can tell if the cooler is making contact by removing it and looking at it. if it is spread around on both the CPU and bottom of the cooler, it is making contact. You never mentioned anything about a CPU fan...

I removed the paste first,but i rubbed it with a piece of paper for it to spread.
so summary is to

Line/Droplet in center method
Check the heat sink ?

should i know anything else before trying again ?

I'd be willing to bet your (Stock?) heatsink is the fault, especially considering you wern't running a stress test, or anything too demanding at the time. Have a look in your case and check the fan is running correctly.
Check that neither the heatsink or its fan is clogged full of dust.
And my personal bet, check that all four clamps are how they should be. I've dealt with an issue like this before where someone's computer (allbeit an old one) had one of the clamps that had broken/came loose and caused it to shut down immediately upon booting.

It definitely sounds to me like a contact issue with the heatsink. With that said it is still seemingly in contact, otherwise you would shut down immediately. Still very very borderline. Have a good look at it, press down on each side and make sure there's no lee-way each time you do.

Heck, go as far as picking the damn mobo up using the heatsink, if it flings off one side then there's your problem.

Furthermore, if your fan is working correctly, does it sound like an absolute jet engine?

A very serious Jet engine! a clean one though!,i am ordering a NH D14,i am hoping it has a really good mounting method!.
but i need to get this working!,ill work on it tonight,i can pull the entire mobo by the heat sink,i think its cheap clamps may be damaged i have to squeeze them back!.
i hope this would work for now,ill try the Droplet method as my thermal paste spreads fast

Btw could constantly applying thermal paste and removing with denatured alcohol cause any damage to the Copper surface of my heat sink,Or worse the surface of my CPU ?

Don't forget to wipe off all the old paste from the CPU using a 90+% alcohol liquid (Such as Isopropyl), wouldn't want to limit that glorious beast that is the NH-D14.

Thank you ! ill give everything a try and come back here to post to see what worked for me! thanks for now guys!

EDIT! So i went from 100 to 60 while idle,but when i load up a game the Cpu Jet engines and it gets to 100
Could this still be a contact issue ?

EDIT 2: THANK YOU GUYS SO MUCH! I WENT FROM 100 idle to 45 ahaha! thank you!,i used the pea method,and tightened the motherboard to the extreme!
