About this deal

Intel i7 10700k was set to run 4.8GHz on all cores using 1.270V VCore (manual). We had wanted to test the chip at 5.0GHz but the high ambient temperature did not warrant that testing. As the technological demands on processors continue to increase, the importance of effective heat dissipation cannot be understated. The choice between these thermal compounds rests on considerations ranging from thermal conductivity and application suitability to long-term reliability. For enthusiasts and professionals seeking peak performance, the MX-6 emerges as a clear choice, offering enhanced thermal transfer, safety for delicate components, and innovative features such as the MX Cleaner for residue-free maintenance. GC-Extreme I was using only on older GPUs and CPUs and there performance was meh for me, sometimes was on par with EK Ecotherm or Hydronaut but sometimes was worse than cheap TIM Thermal Compounds: Arctic produces thermal compounds, also known as thermal pastes, which are used to improve the heat transfer between a CPU or GPU and its heatsink. These compounds fill microscopic gaps between surfaces to enhance thermal conductivity.

Arctic Cooling products are popular among PC enthusiasts, gamers, and professionals who are looking to optimize their computer’s thermal performance. The company focuses on providing cost-effective cooling solutions without compromising quality. Arctic MX-4 Most quality thermal compounds are non-electrically conductive. This is important because it prevents accidental electrical connections between the conductive parts of the CPU/GPU and the heatsink, reducing the risk of short circuits.

SYY-157 is again good paste, easy to spread, cheap and performance is on par with TFX or Kryonaut, that thermal paste will not dry out after while, used that on few builds and no issues, this TIM I was using on my another RTX 3090 and no issues, temperatures was within 1-2°C from TFX and core to GPU hot-spot delta was in 8-10°C As mentioned already, this variant of MX-5 comes with an ARTIC branded Spatula. The user can use the spatula to evenly spread the thermal paste. The MX-5 has low viscosity making it more liquid than the MX-4. Hence it is easy to apply. The tube has ARCTIC branding over it.

The chip was drawing power of nearly 156W so we still have enough thermal heat output to deal with. Answer: Arctic MX-5 faced issues with irregular durability, premature hardening, and overall consistency in some batches, leading to its discontinuation. These concerns prompted Arctic to replace it with the improved MX-6 thermal compound. A stress run of 30 minutes was made using AIDA64 Extreme (FPU). Temperature values on all cores are taken at the end of the result.CPU and GPU Coolers: Arctic manufactures a variety of air and liquid coolers for CPUs and GPUs. These cooling solutions help dissipate heat effectively, allowing for better performance and lower temperatures. Case Fans: Arctic offers a range of case fans with different sizes and performance levels. These fans are designed to enhance airflow within a computer case, which is crucial for maintaining optimal temperatures. Durability and Consistency: MX-5 faced issues with durability and consistency, leading to its discontinuation. MX-6 was introduced as the successor with improvements over both MX-4 and MX-5 in terms of performance and reliability. Slightly better thermal conductivity (9.8 W/mK) than MX-4, with improved temperature range (-40°C to 180°C).

Please note that not every run of the stress test may yield the same result. This could well be due to many factors like mounting pressure, thermal paste application, varying ambient temperature. Not to mention the silicon differences even among the same category of the chips. Hence, it is pertinent to mention the testing methodology along with the specifics. Thermal compounds, also known as thermal pastes or thermal interface materials, play a crucial role in the thermal management of electronic devices, particularly in computers. Their importance lies in their ability to improve heat transfer between two surfaces, typically a central processing unit (CPU), graphics processing unit (GPU), or other chip, and a heatsink or cooler. What changed is the viscosity of the MX-5 compared to the MX-4. While all this is great on paper, some batches of the Arctic MX-5 showed irregularities in durability, premature hardening, and overall consistency. As a result, Arctic decided to retire the MX-5 in favour of a new and upgraded product. Specifications Manufacturer Properly applied thermal compounds can contribute to maintaining lower operating temperatures for CPUs and GPUs. Lower temperatures can lead to improved performance and longevity of these components.

Technical Documents

Thermal Resistance: MX-6 has a lower thermal resistance (0.01275 K/W) compared to MX-4 (0.0155 K/W). Lower thermal resistance indicates better heat transfer capabilities.

We were able to find the mixture of substances used in the MX-5 as can be seen in the above picture. These are not hazardous. Viscosity and Application: While MX-6 has a higher viscosity compared to MX-4, it has properties that prevent leakage due to the Pump-Out Effect. This ensures consistent performance over time and reduces the risk of the thermal paste “pumping out” from between the CPU/GPU and heatsink due to heat cycling. ARCTIC, one of the leading manufacturers of low-noise PC coolers and components, officially launches its MX-5 thermal paste today. The newly developed, high-performance paste comes with an ideal set of thermal properties, guaranteeing reliable heat dissipation over long periods of time. ARCTIC MX-5 is available now in variants ranging from 2 to 50 grams, with and without spatula. If you know about the world-famous MX-4 then you already know of ARCTIC! They started in 2001 with the name ARCTIC Cooling and has evolved into a much more popular and reliable cooling solution provider now known as ARCTIC. Their bases of operation are in Switzerland, Germany, Hong Kong, and the USA with the availability of their products in over 45 countries. Quiet cooling without performance compromise is their motto. Their product lines include CPU Coolers, Case Fans, Thermal Pastes, Charging solutions, Audio solutions, and monitor stands to name a few.The values on the graphs are calculated by taking the average of all cores temperature values and deducting ambient temperature from the average value to yield delta temperature values. Arctic Cooling MX-4 or MX-5 I was using on 3 builds in past and to the date(I built them like 8 months ago) I didn't replace TIM there, temperatures are still same and took apart only one of build and from TIM spread and viscosity of TIM, TIM is still okay and didn't dry out on GPUs, all 3 builds are running 3080 or 3080Ti and 3090 When the paste was placed on the IHS, it gave the impression that it is almost liquid (low Viscosity). The quantity shown in the picture is not used as it is only to show the thermal paste. A blob method was used to test the thermal performance. The surfaces of processor chips and cooler floors are covered with microscopic dents; ARCTIC‘s MX-5 thermal paste is composed of carbon micro-particles which fill these cavities guaranteeing that heat is dissipated efficiently from the heat source. Test results were dropped if the mounting pressure was found not enough as indicated by the spread of the thermal paste. And the test was repeated so as to have validated results.
