Implementing thermal paste in a straight line can reduce GPU temps by 5C

by Mark Dylan

In context: A single of the oldest debates in Pc constructing centers on the accurate way to apply thermal paste. A single blob, a number of blobs, a cross, or a butter spread? Igor’s Lab not too long ago tried using to evaluate strategies, but only for GPUs, whilst the discussion ordinarily considerations CPUs.

A new test from Igor’s Lab implies making use of thermal paste in a “sausage-like” straight-line down the middle is the best strategy, at least for graphics processors. The results come with caveats and are not likely to resolve age-outdated arguments about how ideal to unfold the paste on a CPU.

Igor examined a few thermal paste solutions on a reference RTX 3080 running Furmark even though applying Alphacool’s Aurora GPX-N drinking water backplate and the exact same company’s Apex thermal grease at a 20C area temperature. A Do-it-yourself liquid cooler, while a bit labor-intensive and not as low-cost as a pre-set up air cooler, can save cash compared to shopping for a liquid-cooled GPU.

To make certain reliable test outcomes, Igor took treatment to properly clear the GPU ahead of making an attempt each and every system. He then expended 10 minutes warming it and 5 minutes measuring the temperature.

The sausage system realized temperatures close to 3C cooler than implementing a single dot (which Intel suggests for CPUs) and 5C cooler than spreading the paste across the floor of the GPU. On the other hand, an important detail is how Igor screwed the cooler on to the GPU, firmly placing the screws on a person aspect, then the other in advance of tightening the two. Igor claims that GPU brands do this to use pressure to the paste properly.

Another caveat is that the line approach appreciably differs with larger, large-close GPUs. Igor admits that the regular dot fashion is probably great more than enough for smaller sized mainstream GPUs (like the RTX 3060, which is increasing in Steam’s survey charts) because they have significantly less area to go over.

Even if you aren’t fascinated in the test, the short article presents a comprehensive tutorial on implementing thermal paste, whether or not for GPUs or CPUs. It covers steps like cleaning the processor’s area, paste viscosity, and securely attaching the cooler.
