Where to get thermal paste? [Solution]

Computers overheating are one of the most annoying things in the world, especially when they run perfectly for years and then suddenly start responding without warning. The bad guy? thermal paste.

When heat moves through an object, it causes expansion (also known as “conduction”), meaning certain materials like metal expand more than others depending on how hot something gets. For example, copper expands much less than iron at elevated temperature, while aluminum expands only slightly. In this way, metals transfer heat better by conducting it faster or slower depending on their physical characteristics.

The same principle applies to thermally conductive connections used in laptops and desktop PCs to dissipate the heat generated during use. These substances are called thermal pastes because they were historically made from silver-filled silica gel (as opposed to other ingredients).

Because computer processors generate so much heat, these connections have evolved over time to become more and more effective at transferring heat from devices.

Heat sinks and fans remove excess air and moisture to prevent short circuits due to static electricity. But if there’s no proper path for the heat to pass through, even the best cooling system won’t do the job right. It turns out that proper application between the processor and its heat sink allows heat to dissipate efficiently. This makes thermal paste one of the cornerstones of PC design.

That said, not everyone has easy access to high-quality thermal grease. Fortunately, companies like Intel offer

We’ve got some tips on where to find those examples below.

Where to get thermal paste


If you already shop at Amazon regularly, it’s probably worth checking to see if the company offers free shipping on items like thermal grease. Most products ship within two days via standard delivery. However, it is still helpful to specifically check for deals offered by third parties that sell goods directly on Amazon Marketplace.
It takes some searching, but once you know exactly what you want Amazon tends to offer lower prices compared to sites outside the US

One perk of shopping here: Amazon typically accepts returns of defective products sent by suppliers, rather than requiring customers to return defective parts themselves.

In general, however, ordering something from Amazon costs quite a bit more than elsewhere, simply because the site receives such a large portion of the proceeds from its sales from retailers.

Local DIY stores

You might think finding cheap thermal grease would mean going to Fry’s Electronics or Micro Center, but local hardware stores aren’t always great places to buy things online, either. While both big-box retailers have a lot of cool gadgets, neither has dedicated electronics. Instead, you’re better off going to an independent store. Check the Yellow Pages under Shop Locally for offers. Also search Google Maps for nearby stores.


For example, Newegg sells a wide variety of electronic equipment, including CPUs, RAM sticks, graphics cards, and gaming peripherals. All these items are clearly marked with pricing information, photos and detailed descriptions. You can filter the results by brand, price, and reviews to narrow down your choices. And if you live near a store that sells a specific item, you can use the website’s built-in map feature to easily find it. Unfortunately, Newegg doesn’t accept international orders, although you can get around that restriction by purchasing items from eBay.

Another popular choice among consumers is NCIX – formerly known as No Credit Needed Internet Exchange – which specializes in providing affordable tech accessories, especially video game consoles, TVs, DVD players and home theater equipment. Unlike many eCommerce websites, NCIX ships worldwide. To save money, place multiple purchases together, at checkout, or in advance. Some services charge extra for expedited shipping. While NCIX generally charges higher shipping rates than other sites, they guarantee fast delivery and excellent customer service.

Best Buy

Best Buy also allows users to compare prices for similar items side by side. After selecting products, Best Buy displays the estimated total cost of each purchase, along with shipping charges and taxes. Customers can see exact prices for individual models in various locations in North America. Like Newegg, Best Buy ships internationally, although you must select the country destination before making a purchase.


First, let’s talk about why adding thermal paste is important. Heat naturally rises to colder objects (like the ground), but if it’s not dissipated quickly enough, it will eventually build up to the highest possible point – that is, the surface of the device it’s inside .

That’s when it gets stuck and starts to radiate energy back to the environment, heating everything around it. A poorly designed case can exacerbate this problem as it can block airflow near the motherboard.

That is why manufacturers use thermal grease (or compound) to ensure efficient conduction of heat across gaps. And unlike many other brands available today, high thermal performance doesn’t come cheap. You will pay anywhere from $5 to several hundred dollars per tube based on material type and purity.

However, the correct application of thermal paste is essential to achieve maximum heat dissipation. Using a low quality product may simply allow the heat to build up instead of moving with it.

Poorly applied thermal paste also creates voids that allow moisture to seep in, accelerating corrosion and decreasing overall reliability.

Also keep in mind that incorrectly installed thermal paste often needs to be replaced after installation. With the wrong formulation, the paste can harden too quickly, causing premature failure. Worse, poor thermal contact can cause components to run hotter than normal, leading to premature shutdowns or crashes.
