Abstract

A method of thermally managing an information handling system includes executing a security scan to simulate a maximum workload consuming an electrical power, and receiving sensory signals representing temperatures associated with the information handling system. A system ambient capability above an ambient temperature when operating the information handling system at the maximum workload is then determined.

Claims (31)

1. An information handling system, comprising:

a hardware processor; and

a memory device accessible to the hardware processor, the memory device storing instructions that when executed cause the hardware processor to perform operations including:

executing a security scan simulating a maximum workload consuming electrical power;

determining an ambient air temperature during the executing of the security scan simulating the maximum workload; and

estimating a capability of the information handling system above the ambient air temperature during the executing of the security scan simulating the maximum workload.

2. The information handling system of claim 1 , wherein the operations further comprise commanding a fan to operate.

3. The information handling system of claim 1 , wherein the operations further comprise commanding a fan to operate during the executing of the security scan simulating the maximum workload.

4. The information handling system of claim 1 , wherein the operations further comprise commanding a fan to operate at a full speed during the executing of the security scan simulating the maximum workload.

5. The information handling system of claim 1 , wherein the operations further comprise receiving a signal representing the ambient air temperature.

6. The information handling system of claim 1 , wherein the operations further comprise receiving a signal generated by a temperature sensor, the signal representing the ambient air temperature.

7. The information handling system of claim 1 , wherein the operations further comprise determining an excess thermal margin during the executing of the security scan simulating the maximum workload.

8. A method of thermally managing an information handling system, comprising:

executing, by a hardware processor, a security scan simulating a maximum workload consuming electrical power;

determining an ambient air temperature during the executing of the security scan simulating the maximum workload; and

estimating a capability of the information handling system above the ambient air temperature during the executing of the security scan simulating the maximum workload.

9. The method of claim 8 , further comprising commanding a fan to operate.

10. The method of claim 8 , further comprising commanding a fan to operate during the executing of the security scan simulating the maximum workload.

11. The method of claim 8 , further comprising commanding a fan to operate at a full speed during the executing of the security scan simulating the maximum workload.

12. The method of claim 8 , further comprising receiving a signal representing the ambient air temperature.

13. The method of claim 8 , further comprising receiving a signal generated by a temperature sensor, the signal representing the ambient air temperature.

14. The method of claim 8 , further comprising determining an excess thermal margin during the executing of the security scan simulating the maximum workload.

15. A non-transitory computer-readable device storing instructions that when executed cause a hardware processor to perform operations, the operations comprising:

executing a security scan simulating a maximum workload consuming electrical power;

determining an ambient air temperature during the executing of the security scan simulating the maximum workload; and

estimating a capability of an information handling system above the ambient air temperature during the executing of the security scan simulating the maximum workload.

16. The non-transitory computer-readable device of claim 15 , wherein the operations further comprise commanding a fan to operate.

17. The non-transitory computer-readable device of claim 15 , wherein the operations further comprise commanding a fan to operate during the executing of the security scan simulating the maximum workload.

18. The non-transitory computer-readable device of claim 15 , wherein the operations further comprise commanding a fan to operate at a full speed during the executing of the security scan simulating the maximum workload.

19. The non-transitory computer-readable device of claim 15 , wherein the operations further comprise receiving a signal representing the ambient air temperature.

20. The non-transitory computer-readable device of claim 15 , wherein the operations further comprise receiving a signal generated by a temperature sensor, the signal representing the ambient air temperature.
