You definitely need thermal paste for a CPU cooler. Sep 6, 83 0 4, 7. It would do more harm then good to not use it, so really ask yourself why not? FinalDrive :. VincentP :. But you also have obviously never put a heatsink on without thermal paste before and monitored what happened. In my first hand experience, nothing bad happened, ever. Paste is designed to HELP transfer heat, and btw there are alot of cases where thermal paste HARMS the transfer of heat, aka badly applied, old, generic brand that insulates instead of transfering heat, ect ect.
Until u, yourself, actually does it, u shouldn't comment. Its smart to use thermal paste sure, it will lower your heat sure, but u do realize what modern cpu's and gpu's are rated to withstand heat wise right? Lastly, don't call people fools. This is a debate, no need for personal attacks, sometimes being wrong or misinformed is hard to deal with but try to take it as a learning experience.

Sep 21, You can buy small tubes of thermal paste at electronics stores, sometimes accompanied by a small shovel-like tool called an applicator. When you're building a PC, you'll need a tube of thermal paste for your PC to run smoothly. Some CPU heat sinks come with thermal paste pre-applied to it so you can install it and go. Some hardware enthusiasts, however, will swear by and manually apply their favorite brand of thermal paste.
The role of thermal paste is to help transfer heat away from the CPU and into the heat sink. The heat sink then expels the heat away from the hardware. This keeps the CPU cool, especially when it's hard at work processing tasks.
You may also find the term "stock thermal paste. However, some manufacturers skimp out on the thermal paste and use a compound that's not very effective at conducting heat. As such, enthusiasts will often replace this stock thermal paste with their preferred brand of "aftermarket" pastethe stuff you buy off the shelves. CPUs can get very hot, so it's essential to draw heat from it as quickly as possible.
Unfortunately, air is a terrible conductor of heat, so there needs to be as little air as possible between the CPU and the heat sink for optimum transfer. If you've prodded around inside a computer, you'll know that the heat sink presses tightly against the CPU. This seal may seem good enough to stop air from getting in; unfortunately, even a tight squeeze isn't enough to keep air out. The surface of the CPU and the heat sink's contact plate is covered in tiny grooves and gaps.
If not properly sealed up, these gaps allow air between the processor and the heat sink, reducing the heat transfer efficiency between the two. This is where thermal paste comes in. Not only is thermal paste a good conductor of heat, but it can get into those small gaps and grooves on the surfaces of the hardware. This creates an air-tight seal and increases the rate of heat transfer. Over time, the thermal paste will get old and dry.
The dryness reduces its effectiveness and causes the CPU to get toasty. This occurrence is why people suggest re-applying the thermal paste to prevent a computer from overheating.
You may think that thermal paste isn't as essential in a PC build than the processor or power supply. While a computer will boot without thermal paste, the problem will be keeping it alive while you use it! For intensive programs like computer gaming , a CPU works very hard and can potentially get very hot.
Overclocking also increases thermal production. A heat sink is a device that clamps on to the CPU, designed to draw heat away from the chip to protect it. The bottom surface of the heat sink is designed to be extremely smooth to maximize surface-to-surface contact with the CPU. But imperfections and pits in the CPU wafer allow tiny gaps that reduce the effectiveness of the heat sink. This is where thermal grease comes in. This is a thin layer of one of a variety of compounds that thermally binds the CPU and heat sink together.
