Appendix E: System Thermal Results - Onlogic HX310 Product Manual

6.4 - Appendix E: System thermal results

The thermal performance of the Helix platform was validated by fully loading system components
while the test system was exposed to the limits of its rated environment (0C-50C). CPU clock speeds
and core temperatures were measured for the duration of the test. The results were analyzed by
comparing the average clock speed over the duration of the test to the rated base clock speed. A
passing result was defined by an average clock speed no less than 20% of the rated base clock and
operation below the CPU Max temperature limit.
HX300 -Elkhart Lake SKU 3 1800mhz base clock
shows the thermal test results from an HX300 in a thermal chamber over the course of 20 hours at a
workload of 100%. After 17 Hours the 50C thermal chamber was brought down to 0C.
