The video focuses on the value and process of repasting graphics cards to enhance their thermal performance and longevity. Various thermal paste brands and their properties, such as Arctic Silver, MX4, and Kingpin Extreme (KPX), are discussed, emphasizing the significance of thermal paste in maintaining optimal thermal contact. Practical testing involves a Nvidia GeForce RTX 3070 GPU under specific conditions, revealing the effects of thermal paste on temperature stabilization and performance.

The video elaborates on the meticulous steps for disassembling a GPU, applying new thermal paste, and reassembling the card, including handling thermal pads and avoiding damage to components. Techniques for cooling down the GPU, maintaining accurate thermal pad placement, and achieving even compression are highlighted, alongside considerations about potential risks and benefits of repasting, especially for heavily used GPUs. The speaker concludes that repasting can significantly benefit older or heavily used graphic cards, though it’s less critical for new or factory-sealed models. The theme underscores maintenance practices to avoid thermal degradation and sustain GPU performance.

In this part of the video, the presenter discusses the value of repasting a graphics card, particularly focusing on a mid-range, older model to determine the benefits. The segment covers various thermal paste types, their effectiveness, and when to consider repasting. Additionally, the presenter examines different thermal paste brands like Arctic Silver, MX4 from Arctic, and KP Extreme, highlighting their properties and usage. Furthermore, there’s a brief advertisement for the new MV7 full tower PC case from Fantex, emphasizing its features such as airflow, GPU cooling, cable management, and integrated DRGB lighting.

In this part of the video, the speaker discusses the performance and characteristics of various thermal pastes used for cooling graphics cards. Key points include the resilience of Kingpin Extreme (KPX) thermal paste, which remains soft and can be easily revived with warmth, and the versatile use of Thermal Grizzly products, known for bridging the gap between everyday thermal pastes and high-end options. The speaker emphasizes the importance of thermal paste’s role in filling microscopic gaps between the cooler and the chip, improving thermal contact. They outline the plan to use 3D Mark Speedway to test the out-of-the-box temperatures of a lightly-used graphics card, highlighting the impact of environmental conditions on thermal paste performance over time. The objective is to determine the thermal properties under realistic use conditions.

In this part of the video, the speaker discusses testing the thermal performance of a GPU, specifically a 3070. Key testing conditions include setting maximum core voltage, power, and temperature limits, and locking the fan speed at 75% in an HVAC-controlled room at a steady 71°F. The GPU’s temperature and core clock behaviors are observed until stabilization, with temperatures peaking at 64-65°C and hotspots at around 76-77.9°C. As the entire board heats up, the core clock shows fluctuations from 1980 MHz down to 1965 MHz, highlighting the impact of overall thermal saturation on performance stability. The goal is to ensure that temperatures do not increase after reassembling the GPU post re-pasting.

In this part of the video, the discussion focuses on mitigating thermal degradation to improve the longevity of a graphics card without losing performance. The speaker explains that efficiently managing heat can maintain or even improve performance slightly. Specific actions include cooling the card off properly after testing by running the fans at 100% to dissipate heat from the entire PCB, and carefully disassembling the card to apply new thermal paste. The importance of not damaging fan connectors and avoiding the influence of warranty-void stickers is emphasized, advocating for the right to repair. Detailed steps include identifying and unplugging connectors, loosening the cooler for easier handling, and keeping track of screws using a grid method.

In this segment of the video, the speaker details the process of disassembling a GPU for maintenance. Key points include: ensuring all screws are removed before separation to avoid damaging components, with a specific focus on the four spring-loaded screws around the GPU which maintain even pressure. The speaker demonstrates removing the cooler from the GPU PCB, noting the resistance due to aged thermal paste, which is normal. They emphasize the importance of maintaining the positioning of thermal pads even if they tear. The cleaning process involves using isopropyl alcohol on a shop towel to avoid contamination when applying new thermal paste, highlighting the necessity for a clean surface free from old residue.

00:15:00

In this segment, the speaker discusses potential experiments with mixing different thermal pastes without cleaning the remnants of the previous paste to see the effects. They indicate interest in feedback via comments and likes to pursue this experiment. They then describe using a spreader for applying thermal paste on a GPU, emphasizing the non-conductive nature and consistent method they’ve used for years. They proceed to reassemble the GPU and cooler, highlighting the performance of the Corsair Zenon Flex display. During testing, they observe a slight increase in temperature and more stable clock speeds, explaining that freshly applied thermal paste often needs time to meld and reach optimal performance. The segment concludes as they stop the test to let the GPU cool, demonstrating the temperature drop in real-time.

00:18:00

In this part of the video, the presenter addresses an issue with temperature inconsistencies by running the fan at full speed for 15 minutes to cool the system. Upon inspecting the thermal pads, the presenter discovers that the compound is unevenly distributed, indicating compression issues. They identify that torn thermal pads may have overlapped, causing improper contact and increased thickness. The presenter carefully adjusts the pads back into their correct position to ensure even compression. After this adjustment, the GPU shows more stable temperatures and improved performance, with temperatures consistently lower and voltage more stable.

00:21:00

In this segment of the video, the speaker discusses the impact of thermal paste on GPU performance. They highlight how a new thermal paste can provide peace of mind and potentially longer-lasting performance, especially if high-quality paste is used, which won’t dry out as quickly over years of use. However, they point out that most new graphics cards come with adequate factory-applied thermal paste and that repasting a new card might be more risky than beneficial. They emphasize the importance of repasting for used or extensively used graphics cards, like those subjected to mining or heavy gaming, as it can help in maintaining better performance. The speaker concludes that while repasting can offer benefits, it’s crucial to consider the potential risks and the specific circumstances before deciding.
