If you're building a computer, you need thermal paste, or heat paste, to ensure that your computer's processor doesn't overheat. It's a gloopy, silvery material that you squirt between the processor and the cooler to fill in all the micro cavities in their surfaces, enabling a more efficient transfer of heat from the processor to the cooler. The best heatpastes work so well they let your processor run harder and faster, at lower temperatures, making your PC quieter in turn.
You need to replace the thermal interface material every few years, too, so if you haven't opened up your PC in a while, it might be time to give it a spring clean. Gelid Thermal Pad
If your CPU and cooler are clean and ready to go, we can jump right in to applying new heat paste. If they aren't clean, and have old hea tpaste on them, scroll down to the section on how to clean your CPU first.
The key to applying thermal paste is not to overdo it; you only need to use a small, pea-sized bit of paste – anything more would be excessive. As long as you aren't using a conductive heat paste, however, putting on too much won't break anything, it'll just be messy and in extreme cases, can cause your cooler to actually be less effective.
Step 1: Install your CPU in the motherboard if you haven't already, then use the plunger on the tube of thermal paste to squirt a pea-sized amount in the center of the processor.
Step 2: Next, install the CPU cooler while applying top-down pressure to the unit. Note that there is no need to first spread the paste before installing the cooler; the cooler's pressure will evenly distribute the thermal paste.
Step 3: Once the cooler is installed, check the CPU's edges to see if any excess thermal paste has spilled over, and, if needed, wipe it away with a microfiber cloth or paper towel.
If you already have a working machine that needs thermal paste to be reapplied, you'll first need to clean off the old thermal paste. Before beginning, ensure that the CPU cooler has been removed, and you can visually see the thermal paste; it is generally white or gray.
Step 1: Begin by wiping the top of your CPU with the microfiber cloth to remove as much thermal paste as you can without issue.
Step 2: Place the microfiber cloth over the end of the isopropyl alcohol bottle and upend it until some of it has saturated the cloth, then wipe the CPU down until all the old heat paste has been removed.
If you like, you can use cotton swabs soaked in isopropyl alcohol to remove any errant bits of heat paste that are proving tricky to get to, but you don't have to.
Step 3: Repeat the above process to remove any old thermal paste that may be stuck to the underside of your CPU cooler.
Step 4: Now you can move on to applying new heat paste, as per the section above.
This one is up to you, as some leave their heat paste for years at a time without much issue, and some replace it every year. Intel recommends reapplying the solution "every few years" or if you remove your cooler for any reason. Typically, your thermal paste will last you quite a while, but keep an eye on your temperatures, as if they start to rise, it could be a sign your thermal paste is drying up.
Need help with that? Here's how to check your CPU temperature.
Yes, kind of. You have to have something to fill the gaps in between the cooler and the processor, and heat paste is the most common and effective solution. However, if you don't want to re-apply heat paste at least once every couple of years, you could opt for a thermal pad instead.
Thermal pads perform the same job as heat paste, but they're a malleable material with strong thermal conductivity. That lets them transfer heat from the CPU to the cooler efficiently, but without the chance of drying out or degrading, so performance should remain the same for years to come. They don't tend to offer as strong performance as the best heat pastes, but for peace of mind and ease of use, they win hands down.

This fall has been jammed full of PC hardware releases, but AMD had one more big product launch for the year. Today, AMD announced its RX 7000 line of GPUs, based on the new RDNA 3 architecture.
We have a full rundown on how these new graphics cards will compete with the best from Nvidia, and you can rewatch all the announcements as they rolled out down below.
We're on the edge of a new generation of gaming CPUs -- 13th-gen Raptor Lake from Intel and Ryzen 7000 from AMD. If you're reading this on the day it's published, in fact, AMD is set to launch it's next-gen processors tomorrow. But should you care?
AMD and Intel will undoubtedly both come out claiming ownership over the best gaming CPU, but testing consistently shows that gaming CPU upgrades don't have the biggest impact on your frame rate. There's a lot going on in the next generation of processors, so I'm going to help break down how to understand your CPU's role in games and how you can determine when it's time for an upgrade.
