Arctic Silver 5 Thermal Compound - Large Size 12 Gram Tube less than 0.49 micron less than 0.000020 inch Peak: -50oC to more than 180oC Long-Term: -50oC to 130oC 3 to 12 degrees centigrade lower CPU full load core temperatures than standard thermal compounds or thermal pads when measured with a calibrated thermal diode imbedded in the CPU core. A 3.5 gram syringe contains enough compound to cover at least 15 to 25 small CPU cores, or 6 to 10 large CPU cores, or 2 to 5 heat plates. At a layer 0.003" thick, the 3.5 gram syringe will cover approximately 16 square inches.
