Hello everyone. I’m Brandon with Lenovo and I’m here today with the ThinkStation E32 small form factor workstation. Today we are going to be replacing the microprocessor and heat sink fan assembly. This process will take about twenty five minutes, and you may want to have a little experience working with computers before attempting this. The only tool required will be a phillips screwdriver. Before we continue, we need to make sure that we are protected against electrostatic discharge, or ESD. Make sure to shut down the computer and disconnect all cables and accessories from the system. For further information, watch our “understanding electrostatic discharge” video by clicking the link in the description. And now that we’re ready, let’s get started. Before removing the computer cover, we must first remove two thumb screws. So now we’re going to press downward on the release latch, slide the cover towards the rear of the system and remove it. Next we’re going to remove the fan duct. You just want to pull the two clips apart and lift the fan duct straight up and out of the system. In order to remove the heat sink fan assembly we must first disconnect the fan cable from the system board. Next we’re going to loosen four captive screws in a cross pattern. Then we just need to lift the heat sink fan assembly up and out of the chassis. So now we’re going to remove the processor. We’re just going to press down and outward on the lever to open the processor door. Then reach in, grasp the processor by the edges, lift it up and out of the socket. Here we have our replacement processor. When replacing the processor it is important that the triangle marking in the corner of the processor lines up with the marking on the system board. Once you have them aligned, you can place the processor into the socket, close the processor door and press down and inward on the latch to secure it. If you’re not replacing the heat sink then you need to clean the excess thermal compound off of it. To do this I have some isopropyl alcohol swabs. We’re just going to hold the heat sink and gently, in a circular motion wipe the excess thermal compound off of it. Allow the excess alcohol a few minutes to evaporate. Now we’re going to apply the thermal compound. We just want to place a small, pea-sized dab directly in the center of the processor. If you’ve received a replacement heat sink with thermal compound pre-applied you can skip this step. Now we’re going to place the heat sink fan assembly over the socket using the screw holes for alignment. Then we’re going to tighten four captive screws in a cross pattern. Tighten screw one half way. Tighten screw two all the way. Now tighten screw one all the way. Tighten screw three half way. Now tighten screw four all the way. Now go back to screw three and tighten it all the way. We tighten the screws this way to assure the thermal compound spreads evenly. Now we just need to connect the fan cable to the system board. Now we’re going to align the fan duct with the fan and press down until the clips lock into place. When replacing the cover, it is important that the tabs on the cover align with the holes in the chassis. So once you line those up, you just want to slide the cover forward. Now we’re going to replace two thumb screws.
