Install a CPU


Introduction: Install a CPU

Instructions how to install a Central processing unit.

Step 1: Get Ready!

Eliminate any chance of frying your new CPU with static electricity. Your body can carry a slight electric charge. To discharge your body of static- touch something metal occasionally.

Step 2: Up Next!

Processors, can be different, so you don't want to swap out a Pentium 4 with a AMD Sempron . They are not compatible, unless you plan to build an entirely new system. If you are unsure your new CPU will fit in your current system, Go to the program CPU-Z will tell you everything about your computer. Remember to verify that the socket on your motherboard will fit the new CPU.

Step 3: Lets Get Started

Open up the case of your computer. The CPU is housed underneath the big object (heat sink) which is usually Silver or Copper. There is a fan over the heat sin, but I removed it for the picture.

Step 4: Let It Free!

Most heat sinks have a release tab (picture). Remove the heat sink with this release tab.(keep in mind to discharge) After you remove the heat sink the CPU should be visible.

Time to take out that old CPU!
Nearly all CPUs use ZIF (zero insertion force) style for removal and insertion of the processor. Just take the handle and pull up until it clicks. The CPU should now be ready to be removed. When pulling the CPU out be careful, do it slowly and be sure not to bend a single pin.
Unpack your new CPU and install it. Line up the arrows. When you are finished lock the CPU in and if needed apply thermal paste(heat transferring paste and is very cheep), but only use a small amount. Finally lock the heat sink and fan in place close up the case and see if it works. Good Luck!

    I'd like to see your silver heatsink. I would buy it from you lol. Its aluminum or copper, silver is much to expensive to be used for a normal heatsink. It offers minimal advantages over copper anyways.

     an hour?!? lmao, unless you have a 50 pound heatsink it's unlikely that it would take more than 5-10 minutes to cool to room temp.

     Fair enough, have you ever stuck your finger on a bare processor and powered it on?? It's like an endurance test of who can hold the cast iron pan the longest.

    Even old pentium 1 processors (the 233 MMX ones) can get VERY hot in a short amount of time.

    Also don't forget to add thermal paste or the processor temps can rise too high. Especially if there is old thermal compound on the heatsink. It needs to be scraped off and thermal paste put on.

    well, I should have added that but for this install it was a socket 478 p4 2.40 ghz which i never applied thermal paste although on the bottom of the heat sink is a pad.

     I recommend using one or the other, using a thermal pad and thermal paste together would make a huge mess for you later.. trust me. Really you don't need ANY kind of thermal material in there, so long as the heatsink sits FLAT on the processor, but the use of a thermal transducer helps transfer the heat a bit.

    then you dont need paste but dont take my word ,do your own research

    actually it was a P4 socket 478 and the heat sink had a thermal pad, I think someone else needs to do there research
