Review on 🔥 ARCTIC MX-4 (with Spatula, 8 g) - High-Performance Thermal Paste for CPUs, GPUs - PC, PS4, XBOX- Enhanced Thermal Conductivity, Longevity, Safe Application, Non-Conductive by Geoff Foster

I replaced the old OEM thermal paste on my late 2010 Lenovo ThinkStation S20 with this one. I've tried the "5 point" method and the "pea sized ball" method (using a slightly larger ball due to the larger chipset/IHS on the old hexacore Xeon W3680 processor). I did before and after measurements and noted the ambient temperature with the BIOS set to "normal" fan control. I found: 1) Using the "pea sized ball" method outperformed the "5 point" method on my Xeon) with an MX-4, but with much lower fan speeds (200-600 rpm lower with a CPU fan). The BIOS seemed to aim for an average temperature of 72 C, with the cores ranging between 68 and 76 C. One more note, I bought this to replace an Arctic Silver 5 bulb that I've been using for years. It's a little easier to use. I found that AS5 was not "shelf stable" and was disconnected, requiring either remixing or removing the first bit before use. It also left stringy marks. MX-4 appears to be much more consistent and easier to apply accurately.
