hey there guys, first i'd like to apologize if i wrote in this wrong section of the forums, i'm kinda newbie here.
My question.... so recently i decided to upgrade my computer specs.

-msi x79a-gd45 Plus mobo
-intel i7 4930k
- 2 evga gtx 760 sli
-850w psu
- 2 western digital HD 500 gb each
- 2 x 4 gskill ddr3 2400

i swapped my intel i7 950 bloomfeild, my mobo to support the new i7 4930k and added 2 gpu's.

Everything ran fine, except my new cpu.

When i swapped mobos and cpu i attached the stock i7 950 heatsink fan to the new mobo and the i7 4930k ran incredibly hot, (75-84c idle).

so i then purchased the Noctua NH-D14 Heatsink fan, (thinking i couldnt slide with my stock heatsinkfan that came with the 950). and its still 80c idle!! what gives?? anyone? why is my cpu so dang hott on idle... i never overclocked it or touched any other component when i got the new pc parts. i ran a windows index and the numbers for every other component gave me 7.2+/ 7.9 but my i7 4930k score was 3.1/7.9. Something is definitely wrong with my cpu but i have no idea what it is... help :(

I also applied diamond thermal compound..

you pc is slow because of cpu overheating and 80c at idle is extremely high at stock cooler the idle temps should be around 30c and 80c is even high if the cpu is at 100% load and u are using noctua d14 so the temps should be much less.
remove the previous TP by isopropyl alcohol then put just a drop of new TP not much or the result will be opposite and spread it evenly with a credit card or something made of plastic dont use metal objects.

RobCrezz thank you for the quick reply man, much appreciation! I shall reapply the thermal paste the noctua came with and post results.

IS it common for the cpu to run so incredibly slow for a i7 4930k at 80c stock/idle? when i tried to update windows it took me about 3-4 hours LOL. the i7 950 took me less than 30 minutes to do a clean wipe and windows.

MY computer is so slow right now, that i could type faster than the actual keys being displayed. LOL. does cpu high temp (now 80-84c) relate to how fast this baby should be?
Thanks again man.

HOLY MOLY. i should probobly turn this thing off before it explodes, i will reapply paste/heatsink (again) and see if it solves the issue on why i'm able to type faster than my computer cpu (LOL).

Yeah you should, that explains why its running so slow, as the processor lower the clock speed and voltage to protect it self.

I thought credit cards are only for shopping. Never knew it is useful for applying the thermal paste evenly on a surface of a processor xD

Dont bother, its a bad method for applying thermal paste imo - coverage isnt important, filling the gaps is.

its not at all a bad method, nothing bad happens like that a lot of people apply TP like that for their PC and droping and pressing the heatsink is done by shops to save time and energy.
and whats bad about that method ???????? does it harm the CPu does it affects the cooling ??

Its bad because its inconsistent in its results and much harder to get right.

The whole point of TIM is to fill the small gaps, you cannot possibly see these with your eyes to be able to know where to put more or less paste.

The method of putting a small blob and letting the heatsink pressure spread it is more consistent as it will naturally fill the gaps between the heatspreader and the heatsink.

Coverage of the heat spreader isnt important, filling the tiny gaps is.

Even Tomshardware state that the method of letting the heatsink spread it is best.

Heres an article and expert opinion:
http://www.tomshardware.com/reviews/thermal-paste-heat-sink-heat-spreader,3600-5.html

"In light of the hot spot discussion, however, we believe that smearing paste on the whole CPU is quite pointless and a thing of the past."
