Step 1: Replacing Your Intel Stock Cooler
English is not my mother tongue, so also I am sorry for any grammar mistakes.
So you want to change your stock cooler, with something bigger, for overclocking purposes or just for fun. Here are the steps.
Open the side of your case (usually 2 screws holding it). You will see something like this.
Now if your new cooler has a back, that needs to mount on the motherboard, then you need to remove motherboard from the case.
Usually it's 6 screws holding it ( blue marks). You need to unmount cables also ( green marks), you can write them down if that makes it easier to help you.
On the other side use your four black spacers and above them place your 2 Intel mounting brackets (cooler has also AMD brackets but we cover the Intel in this instructable).
Use the 4 LGA2011 screws to your mounting brackets.
Remove the old thermal paste from your cpu, using Isopropyl alcohol-recommended- or you can also use <70% acetone if you like.
Be careful don't spill it on your motherboard, use a coffe filter to rub gently your cpu. Be sure it's absolutely dry/free of moisture.
Apply new thermal paste, I used mx-4. One dot of paste is enough.
Place the cooler, and the 1 crossbar that comes with it, on top of it.
Use the 2 M3 screws carefully screw them equally to hold your cooler in place.
Place the 4 anti-vibration mounting arms and slight them in place to hold your fan.
Place your fan and mount the four pin socket on your motherboard.
Put everything again inside your case, mount everything you removed ( always double check).
