Use screwdriver to remove panel screws if the panel has them Once the screws are removed, pop the panel off. If the CPU is air-cooled Unplug the cooler's fan from the motherboard Unscrew the cooler from the motherboard If the CPU is liquid-cooled Unscrew the cooler's waterblock from the motherboard.
Using isopropyl alcohol, clean the cooler's patch of any thermal paste. Remove the processor without touching the pins on the socket or processor as this can bend the pins If you plan to reuse the processor, remove the old thermal paste using isopropyl alcohol. Locate the corner of the CPU socket marked with a triangle and line it up to match the corner of the new processor with the triangle Gently drop the new processor into the CPU socket Lower the retention arm of the socket to lock the processor into place.
AI-intensive strategy games, however, can put some serious demands on your processor. The best way to check your CPU is to test your system running something from your favorite genre, or a new, demanding game you can use to push your system to its limits. With HWMonitor running, launch your chosen game and get past the menus. The likely scenario for a modern 3D game is that your GPU will be the one doing the heavy-lifting.
So, what do you do now? Well, you need to know what specifically is holding back your chip—is it simply too slow, or does it not have the required multi-threading performance? With the previous game still running you can have a quick check. The Windows 7 task manager looks a bit different than the Windows 8 one below, but shows you the same information.
If only a single thread is being pushed then you simply need a speedier chip. If all the cores are being pushed to their limits, you might need both a faster and a more heavily multi-threaded processor. Another handy application for your upgrade quest is CPU-Z. The free download will give you a full run-down of the main components of your machine.
Once downloaded, run the application to see the details of your processor laid bare. Just use common sense here: Unscrew whatever needs to be unscrewed, and don't pull too hard if something doesn't come loose at first. If you have any trouble removing it, find the model number and look it up online. Someone may have tips on how to remove it safely. Technically, the world wouldn't end if you leave old thermal paste on your heatsink or fan.
But since you're about to apply a new coat anyway, it's better to get rid of the old stuff and start fresh. You don't want a layer of thermal paste on top of another layer of thermal paste, since this would reduce its conductivity and render the heatsink less effective.
Luckily, old thermal paste is very easy to remove. Just use some rubbing alcohol and a paper towel. If you get a few drops of alcohol elsewhere in your computer, it's not going to do any harm; just make sure you don't get any stray bits of paper towel in there. Under the heatsink or fan, you'll see the old processor in its housing. There should be a small metal lever somewhere to lift the housing off.
Word to the wise: You may have to gently press the lever down and to the side first. As with other steps in this process, if you find yourself pulling hard on a component, you're probably missing a very easy, gentle way to remove it. Once you've raised the housing, all you have to do is lift the processor out.
There's nothing else securing it. In what is, by far, the simplest part of the whole process, gently place your new processor down where your old one used to be. There will be two small indentations on the side of the processor, so make sure that they match up with the indentations in the housing. You'll know the processor is in correctly when it's sitting flat. Then, lower the housing and secure it with the metal bar again. If you ask online, you're going to get a lot of opinions about the "best" way to apply thermal paste.
Drawing an X, making a cross, spreading it in advance, letting gravity do the work — there are plenty of methods, and some evidence in favor of and against each one. The short version is that unless you're building some kind of supercharged, overclocked powerhouse, how you apply thermal paste is not going to make or break the machine.
I personally went with the "grain of rice" method, and made a very small ball right in the center of the processor. The heatsink — and the heat of the processor itself — should take care of spreading it over time. Basically, when it comes to thermal paste, less is more, and you can always redo it if you find that your computer is running way too hot. It's the most open-ended part of the procedure, but it's not the hardest, unless you drive yourself crazy over it.
Whatever you did to take the heatsink or fan out, reverse the process. Screw everything back in tightly, but not so tightly that it will bend or break the cooling unit's structure. You're done!
