Why Do This?

Agar aapka MacBook overheat ho raha hai ya fans continuously loud chal rahe hain, toh ho sakta hai heat sink ya thermal paste weak ho gaya ho. Heat sink ko nayi thermal paste ke saath replace karke aap cooling improve kar sakte ho.

Tools You’ll Need

  • Phillips #00 screwdriver

  • Spudger (plastic pry tool)

  • T6 Torx screwdriver

  • New thermal paste (high-quality like Arctic MX-4 recommended)

Step-by-Step Instructions

Step 1: Remove Lower Case

  • MacBook ko ulta flat surface par rakhkar 10 bottom screws remove karo:

    • 7 short (3 mm)

    • 3 long (13.5 mm) near the hinge

  • Lower case ko gently slide karke rear edge se remove karo.

Step 2: Disconnect the Battery

  • Spudger se battery connector ko logic board se gently lift karke disconnect karo. Safety ke liye ye step zaroori hai.

Step 3: Disconnect the Fan Cable

  • Fan ke connector ko logic board se gently spudger se pull karo—thoda twist se asaan hota hai. Break na ho jaaye, isliye gently karo.

Step 4: Remove the Fan

  • Fan ko case se remove karne ke liye teen screws (one 7 mm T6 Torx, two 5.4 mm T6 Torx) ko alag-alag remove karo.

  • Fir fan ko carefully upper case se lift karke nikaal lo.

Step 5: Disconnect Display/Data Cables

  • Display data cable ko dhyan se sideways pull karke disconnect karo—kabhi upar ki taraf mat kheencho.

  • Subwoofer, camera, and other connector cables ko bhi gently unplug karo.

Step 6: Remove the Logic Board

  • Logic board ke connectors aur screws hatane ke baad (e.g., DC-in board screws, ribbon cable connectors), board ko slightly lift kar ke nikaal lo.

Step 7: Remove the Heat Sink

  • Heat sink ko logic board pe hold karne vale four screws (8.5 mm Phillips) ko carefully remove karo.

  • Suno — har screw ke neeche thoda sa spring hota hai. Make sure ye gira na toh.

  • Fir heat sink ko gently upar lift karke board se remove karo.

Step 8: Clean & Apply New Thermal Paste

  • Processor aur heat sink surface ko isopropyl alcohol + soft lint-free cloth se clean karo.

  • Ek pea-sized drop of new thermal paste dalke even layer spread karo.

Step 9: Reassemble

  • Heat sink ko carefully logic board par place karo, screws wapas diagonally tighten karo for even pressure.

  • Fir logic board, fan, battery, aur lower case sab wapas same sequence mein reassemble karo.

Final Check

  • MacBook ko on karo.

  • Cooling performance check karo—ab fan zyada quiet hona chahiye aur temperature better stable hona chahiye.

Pro Tips

  • Use thin, high-quality thermal paste, and apply just enough—too much can cause overheating.

  • Similarly tighten screws diagonally—pressure evenly distribute hoti hai.

  • Jab MacBook open ho, dust clean kar lena acha hota hai for long-term cooling.
