Applied new Arctic Silver 5 now my AMD 8350 with hyper 212 EVO is running hot.

If you don't want to read the whole thing the base is my CPU is running around 50C to 78C under load, I did pea size dot with credit card spread on my hyper 212 evo connection plate, not on my CPU.


So when i first built my PC, i had no idea how to apply the thermal paste. I did the research and decided to do the credit card spread. that has worked until i decided to redo my thermal paste. I first cleaned the heat sink and the CPU with rubbing alcohol and paper towels. I let it sit for about 10 minutes to let the alcohol dry. I used the old container of Arctic Silver 5 and did the pea size dot in the middle method. that did not work at all. When very first turned it on it turned off after 3 seconds or so. I turned it on again and was able to get to the BIOS for a split second and saw that the temperature was at 80C. So i immediately turned it off to try to save it from burning up. I then took it back apart, cleaned it with rubbing alcohol and paper towels, and did the center dot but added more until it was about a size of two peas. This actually worked and let me used the computer but it was running at 60C idle temp. If I were to try anything it instantly got too hot and I would shut it off. I cleaned it the same way as before but this time in lines and on the cooler instead of the CPU. Since the Hyper 212 is not totally flat i tried to fill in the gaps by doing the lines on it cooler. Put it back together and was running still same temp as my second attempt. So i took it apart AGAIN, cleaned it the same way and did the credit card smear on the cooler, I was hoping it would fill in the gaps between the copper and metal so it would have a flush connection. i turned it on and now it actually runs very cool, but very random. At idle i can see it from 19 C to about 40C depending on opening the internet and such, but while using 3D Mark 11 Demo, it can jump from 50C up to 78C and i still dont really like it running at 78C. I tried to be detailed so you guys know what i have done to get it running cool. Any help will be great!
 
Solution
are you installing the hyper212 correctly? make sure you are using the right brackets and screws.

have you overclocked your CPU and to what speed/vcore voltage?

don't apply the thermal past to the cooler or spread it with a card. apply the paste directly on the CPU (pea to bean size is fine). then make sure you tight up the screws enough for it to make appropiate contact but don't overscrew to break your mobo.

I am installing the 212 the same way it was before I screwed this up. I reset my CPU to defaults so all the volts and clocks should be stock. And I did try the pea size but it was the worst of all my attempts. That one would barely boot into the BIOS before it would overheat and shut off.

I also run an 8350, and I've switched from AS5 to MX-4 these days, myself. I used to use a hyper 212 as well but had similar issues with temperatures under load (I use an Arctic A30 in my 8350 build now, though).

The method I use with heat-piped heatsinks is small lines across the heat pipes. Remember that thermal compound is only meant to fill microscopic gaps, not visible gaps. It's also the heat pipes that are actually removing the heat, so forget about trying to make the connection flush, as that will likely have the same result as having too much thermal compound in general.

I can't recall if AS5 is of a thick consistency, but if you're willing to give something else a try, MX-4 is pretty easy to work with.

Well I was out of options so i decided to try the bean method, since i already tried the pea method. I put the paste parallel with the copper heat pipes. This actually worked! The temperatures are even lower than before i attempted all of this mess. So I call this a win.
