TikToker Cools Its Processor With Diamonds – Does It Really Work?

Anyone building a gaming PC needs thermal paste. Now a TikToker has mixed diamond dust into the paste.

Anyone who assembles a gaming PC needs thermal paste. It comes between the processor and the CPU cooler and is intended to minimize the bumps in the processor.

You can’t even see these microscopic bumps between the two touching metal surfaces. The thermal paste fills these and prevents air from settling in these areas. Thermal paste ensures that the “brain” of your computer stays cool even under load.

A TikToker has now mixed diamond dust into its thermal paste and smeared it onto its processor. In our article we explain whether this really works.

Can Diamond Dust Thermal Paste Really Cool?

Who Tried This? Mryeester or Adam Yee is a TikToker with around 1 million followers on TikTok. On his channel, he tests various computer hardware and is mainly involved in DIY projects.

What exactly is he doing? In his almost 40-second video, he mixed normal thermal paste with diamond dust. He then applied the mixed paste to his processor (via tiktok.com).

In a next step, he then tested the temperatures because he wanted to find out what cools better: the normal thermal paste from the electronics store or his mixture with diamond dust. In the video he also briefly presents the results:

• The temperatures with normal thermal paste are around 49 degrees Celsius.
• With diamond paste the temperatures are around 46 degrees Celsius.

Overall, he can save 3 degrees in this way with an open mainboard. He did not test how the diamond paste affects his processor when he installs the mainboard in a housing.

Manufacturers also offer thermal paste with added diamond

Can this really work? Tech blogger InventGeek also conducted the diamond dust experiment a few years ago (via intentgeek.com). In his test, he used 18-carat diamond powder and also put the mixture on the processor. In his experiment, the temperatures dropped even more:

• With a silver mixture, the temperatures are around 42 degrees or 57 degrees under load.
• With its diamond compound, the temperatures are at 29 degrees or 38 degrees under load.

In his article, however, he also explains that the temperatures can vary greatly depending on the consistency of the thermal paste and how he applies it.

Why does this work? Normal thermal paste often consists of a mixture of silver and silicone grease. After all, silver has a thermal conductivity of 429 W/m K.

W/m K indicates the amount of heat in watts per hour or J/s that is transferred through 1m² of a 1 meter thick material at a temperature difference of one Kelvin.

However, the conductivity of diamond is much higher than that of silver. Because the thermal conductivity of diamond is between 900 and 2320 W/m K. In the best case you have five times the performance of silver.

Can you buy something like this? Some manufacturers now also offer a combination of thermal paste and diamond dust. manufacturer like innovation cooling however, use synthetic diamonds in their mix. So no real diamonds are turned into dust.

But the prices are steep. While you might pay 4 euros for completely normal thermal paste, the prices for diamond dust paste are 25 euros or more.

For people who care about every degree Celsius, this should certainly be exciting and worth the extra charge. For most other people, however, the surcharge should not be worthwhile.
