Abstract

An information handling system includes multiple hard disk drives, a central processing unit (CPU) and memory complex, a graphics processing unit (GPU) and input/output (I/O) complex, multiple cooling fans, and first and second airflow vanes. The cooling fans pull in airflow through the hard disk drives and push the airflow through both the CPU and memory complex and the GPU and I/O complex. The first and second airflow vanes are located between the hard disk drives and the cooling fans. The first and second vanes are in a first configuration when the information handling system is in a CPU and memory centric configuration, and in a second configuration when the information handling system is in a GPU and I/O centric configuration.

First claim

What is claimed is:

1. An information handling system comprising:
a plurality of hard disk drives;
a central processing unit (CPU) and memory complex;
a graphics processing unit (GPU) and input/output (I/O) complex;
a plurality of cooling fans to pull an airflow through the hard disk drives and to push the airflow through both the CPU and memory complex and the GPU and I/O complex; and
an airflow vane located in between the hard disk drives and the cooling fans, the airflow vane in a first configuration when the information handling system is in a CPU and memory centric configuration, and the airflow vane in a second configuration when the information handling system is in a GPU and I/O centric configuration.

2. The information handling system of claim 1 , wherein the airflow vane is coated in an acoustically absorptive material.

3. The information handling system of claim 2 , wherein a thickness of the acoustically absorptive material is set based on a frequency range of an acoustical disturbance.

4. The information handling system of claim 3 , wherein reduction of the acoustical disturbance by the vane maintains input/output (I/O) throughput of the hard disk drives.

5. The information handling system of claim 1 , wherein the airflow vane comprises:
a latch to hold the airflow vane in either the first configuration or the second configuration.

6. The information handling system of claim 1 , wherein the airflow vane comprises:
a pivot mount to hold the airflow vane within the information handling system, and to pivot to enable the airflow vane to transition between the first configuration and the second configuration.

7. The information handling system of claim 1 , wherein the airflow vane comprises:
a recess portion on a first end of the airflow vane, the recess portion provides clearance of the airflow vane with a component of a backplane of the information handling system.

8. The information handling system of claim 1 , wherein the hard disk drives are sensitive to both vibrations and acoustical disturbances.

9. An information handling system comprising:
a plurality of hard disk drives;
a central processing unit (CPU) and memory complex;
a graphics processing unit (GPU) and input/output (I/O) complex;
a plurality of cooling fans to pull an airflow through the hard disk drives and to push the airflow through both the CPU and memory complex and the GPU and I/O complex; and
first and second airflow vanes located between the hard disk drives and the cooling fans, the first and second vanes in a first configuration when the information handling system is in a CPU and memory centric configuration, and the first and second vanes in a second configuration when the information handling system is in a GPU and I/O centric configuration.

10. The information handling system of claim 9 , wherein the first and second airflow vanes are coated in an acoustically absorptive material.

11. The information handling system of claim 10 , wherein a thickness of the acoustically absorptive material is set based on a frequency range of an acoustical disturbance.

12. The information handling system of claim 11 , wherein reduction of the acoustical disturbance by the first and second vanes maintains input/output (I/O) throughput of the hard disk drives.

13. The information handling system of claim 9 , wherein the first airflow vane comprises:
a latch to hold the first airflow vane in either the first configuration or the second configuration.

14. The information handling system of claim 9 , wherein the first airflow vane comprises:
a pivot mount to hold the first airflow vane within the information handling system, and to pivot to enable the first airflow vane to transition between the first configuration and the second configuration.

15. The information handling system of claim 9 , wherein the first airflow vane comprises:
a recess portion on a first end of the first airflow vane, the recess portion provides clearance of the first airflow vane with a component of a backplane of the information handling system.

16. The information handling system of claim 9 , wherein the hard disk drives are sensitive to both vibrations and acoustical disturbances.

17. An information handling system comprising:
a plurality of hard disk drives;
a central processing unit (CPU) and memory complex;
a graphics processing unit (GPU) and input/output (I/O) complex;
a plurality of cooling fans to pull an airflow through the hard disk drives and to push the airflow through both the CPU and memory complex and the GPU and I/O complex; and
first and second airflow vanes located in between the hard disk drives and the cooling fans, the first airflow vane including a latch to hold the first airflow vane in either a first configuration or a second configuration, the first and second vanes being in the first configuration when the information handling system is in a CPU and memory centric configuration, and the first and second vanes being in the second configuration when the information handling system is in a GPU and I/O centric configuration, wherein the first and second airflow vanes are coated in an acoustically absorptive material.

18. The information handling system of claim 17 , wherein a thickness of the acoustically absorptive material is set based on a frequency range of an acoustical disturbance.

19. The information handling system of claim 18 , wherein reduction of the acoustical disturbance by the first and second vanes maintains input/output (I/O) throughput of the hard disk drives.

20. The information handling system of claim 17 , wherein a physical communication with both a vibration source and a vibration sink forces an amount of vibration through the vibration sink.
