In this video we are going to replace the stock Intel cooler with an Arctic Cooling Freezer 7 Pro Rev.2 and then overclock the CPU from 3.7GHz to 4GHz and overclock the memory.
Replacing the Stock Intel CPU Cooler with an Arctic Cooling Freezer 7 Pro Rev.2
We've already removed the stock Intel cooler and cleaned the thermal compound off of the CPU as shown in Lesson 2.
To unbox the Freezer 7 Pro you need to turn it so you can see the specs on the back. There are three plastic fasteners, two on either side and one at the bottom. Once those are loose you can separate the front from the back and slide out the cooler. Lift the cooler up and set it on its back to protect the pre-applied thermal compound. There is an Intel bag with push pins and screws which we will be using. The AMD bag has two metal pieces and screws used for installing the cooler onto an AMD CPU. We won't be needing those so I'll set them aside.
The cooler comes with an Intel mounting plate. On each corner of the plate there are 3 holes for the push pins to go through the mounting plate and through holes in the motherboard. The holes closest to the center of the plate are used for installation onto a socket 775 motherboard. The middle holes are for socket 1156 motherboards and the outer holes are for socket 1366 motherboards. We have a socket 1366 motherboard so we will use the outer holes.
I'll set the mounting plate onto the motherboard so the outer holes are above the holes in the motherboard and the screw holes are facing the front and back of the computer. The push pins are in sets of two. The white shorter one with the arrow head looking tip goes through the mounting plate and motherboard. The other black push pin goes through the first and wedges the arrow head outward to secure the mounting plate to the motherboard.
The push pins are very small so, to make it easier, I will use needle nose pliers to insert them. Insert the white arrow head shaped one first into the outer hole. Once it's partially in I'll let go of it and use the pliers to push it down. I'll insert another white arrow head shaped push pin into the opposite corner of the plate the same way and then the two remaining corners.
Next, I'll get a grip on the head of the black spreader pin with my pliers and push it straight through the white arrow head shaped pin. I'll do the same at the opposite corner from the first and then the final two. The plate is secured to the motherboard. If you need to remove the pins, use your needle nose pliers to pull straight up. Twisting the pins will make them break off.
On the heat sink, the fan is covering up a screw hole we need to get to. The plastic fan is held to the cooler on each side using a notch in the metal cooler. I'll reach through the fan shroud and press outward to remove the fan from the cooler.
Next, I'll lower the heat sink onto the CPU and mounting plate making sure the direction of air flow from the cooler's fan is directed towards the rear exhaust fan. On one side of the cooler, use your philips or plus screwdriver to pass the mounting screw through the hole in the cooler into the screw hole on the mounting plate. Get it started in the hole, but do not tighten it. On the other side of the cooler do the same and snug down the screw. Then go back to the other side and snug it down. Neither screw will tighten completely. You just want to feel some resistance.
Next, I'll re-attach the fan to the heat sink and insert the fans power cable into the CPU fan header on the motherboard.
That's it. The Freezer 7 Pro Rev.2 is installed.
Comparing the Temperatures after replacing the CPU cooler
We're back in Windows after installing the new CPU cooler. I haven't changed any of the settings in the BIOS. We want to compare the temperatures with the new cooler to what they were when the stock Intel cooler was installed. I'll open RealTemp. The CPU idle temperature is now 43c . The idle temperature with the stock Intel cooler, with these frequency and voltage settings, was 62c. That is a 19c decrease in temperature at idle. Let's open Prime95 and compare the load temperatures by running the large FFts test. After 10 minutes the temperature is 75c. The load temp with the stock Intel cooler was 97c. That is a 22c decrease in temperatures at load. This is very good and will give us more thermal room to overclock the CPU even higher.
Overclocking to 3.8GHz
Let's try to get the CPU to 3.8GHz. A base clock of 190 x a multiplier of 20 gives us 3800 or 3.8GHz. Once again the RAM, Uncore and QPI changed automatically. To watch all of our complete video lessons with full written instructions you will need to purchase a login for the site. Buy Now..
