1. Remove Old Cooler & Clean CPU: Begin by carefully detaching your existing CPU cooler. Using isopropyl alcohol and a lint-free cloth, meticulously clean any residual thermal paste from the CPU’s integrated heat spreader (IHS) until it is spotless.
2. Prepare Mounting Hardware: Consult your cooler’s manual and install the appropriate mounting brackets for your specific CPU socket (Intel LGA 1700/1200/115x or AMD AM4/AM5) onto the motherboard. Ensure any backplates are correctly positioned and secured.
3. Apply Thermal Paste: Dispense a pea-sized or rice-grain amount of high-quality thermal paste directly onto the center of your CPU’s IHS. Resist the urge to spread it manually; the pressure from the cooler will distribute it perfectly and evenly.
4. Mount the Cooler: Gently lower the CPU cooler onto the processor, ensuring the base makes uniform contact. For coolers with an offset design, such as the DeepCool AG400, the fan can often remain attached during this step. Tighten the mounting screws in an ‘X’ pattern, alternating diagonally, until they are snug. Crucially, avoid overtightening, as this can damage components or warp the motherboard.
5. Connect Fan(s): Connect the CPU cooler fan(s) to the designated ‘CPU_FAN’ header on your motherboard. If your cooler uses multiple fans, employ a Y-splitter if necessary. It is imperative to connect to the CPU_FAN header to ensure the motherboard can accurately monitor and control fan speeds based on CPU temperature, preventing potential overheating or unnecessary noise.
