Things you’ll need. 1 the motherboard and GPUs from condensation because I have found that the dry eraser tends to not insulate the surrounding surface mounted components from the cold. On GPUs this can especially cause problems on long bench sessions. Use the brush and apply the grease all around the socket (areas marked green) so that the board is coated adequately. If you are overclocking memory using sub-zero cooling, then insulate this area as well, getting all around the DIMM slots. On the back side of the motherboard, apply the grease with the brush covering up pretty much whole top half of the motherboard. For this guide, I will just cover CPU and memory preparation for LN2 overclocking. The next instalment will be covering GPU preparation for single and four way multi-GPU overclocking at which point I will detail what to do with bottom half of board near PCIe slots. After the grease has been applied, take the hair dryer and heat up the board around the DIMM slots and CPU socket to make the grease more viscous so it flows in between the DIMM slots, around the CPU socket and PWM area leaving no critical motherboard surfaces free from grease. I don’t recommend putting grease directly in the CPU socket or DIMM slots as this can lead to hardware detection issues later on. After you have greased the board entirely, clean off the top of the PWM mosfets and replace the motherboard PWM heat-sink. STEP B Now take the foam tape and cut out pieces so they fit neatly around the CPU socket and DIMM area as show in pictures 4 and 5. Make sure there are no gaps or cracks where air can easily get in (example circled in green) and cause moisture/ice. Usually I will double layer the tape first before I start cutting the pieces out so each piece is just the right thickness. On the backside of the motherboard, cut some flat pieces of tape to cover the underside of the socket area and the DIMM slots as shown in picture 6. When applying the foam, tape or pre-cut the socket area pieces to the board, peel the backing off and spread grease all along the sticky side of the cut pieces before you stick them on the board. This is of paramount importance as it forms a nice air tight seal under the tape to keep moisture out. Install the CPU and slide in the CPU mounting hardware/rods. Once you’ve done that, put all the pre-cut pieces around the CPU socket and DIMM slots so we are ready for next step. Issue 20 | 2012 The OverClocker 19
