Heatsink with a plurality of fans
A heatsink includes a plurality of fans mounted to the heatsink. The plurality of fans includes a first fan that provides an airflow for the heatsink and a second fan that selectively modifies the airflow.
1. An apparatus, comprising:
a heatsink;
a plurality of fans mounted to the heatsink, wherein the plurality of fans comprise
a first fan that provides an airflow for the heatsink, wherein the first fan is mounted to a first side of the heatsink,
a second fan that selectively modifies the airflow, wherein the second fan is mounted to a second side of the heatsink;
wherein the first and second fans are positionally offset from each other to provide first and second offsets orthogonal to a direction of the airflow, wherein the second offset is to provide an unblocked portion of the second side of the heatsink associated with a first airflow passage to channel airflow to and from the unblocked portion of the second side of the heatsink formed by the second offset, and the first offset is to provide an unblocked portion of the first side of the heatsink associated with a second airflow passage to channel airflow to and from the unblocked portion of the first side of the heatsink formed by the first offset, wherein portions of the first and second sides of the heatsink are included in a primary airflow passage to channel airflow between the first and second fans through portions of the first and second sides of the heatsink, wherein the first and second offsets correspond to unblocked portions of the first and second sides of the heatsink such that at least one of the first and second offsets is unblockable by a fan that is not turned on; and a controller that selectively operates the first and second fan.
2. The apparatus of claim 1 further comprising the controller coupled to the first and second fans, the controller selectively operates the first and second fans in a mutually exclusive manner.
3. The apparatus of claim 1 further comprising the controller coupled to the first and second fans, the controller selectively operates the first and second fans simultaneously by default.
4. The apparatus of claim 1 further comprising the controller coupled to the first and second fans, the controller dynamically adjusts an airflow direction configuration of the first and second fans.
5. The apparatus of claim 1 further comprising the controller coupled to the first and second fans, the controller dynamically adjusts an airflow in configuration of the first and second fans.
6. The apparatus of claim 1 further comprising the controller that controls the first and second fans based on a monitored temperature associated with the electronic component and a monitored power consumption for each of the first and second fans.
7. The apparatus of claim 1 wherein the first and second fans are on opposite sides of the heatsink.
8. The apparatus of claim 1 wherein the first and second fans are on non-adjacent sides of the heatsink.
9. The apparatus of claim 1 wherein the first and second fans are on adjacent sides of the heatsink.
10. The apparatus of claim 1 wherein the controller controls the first and second fans such that a first fan speed exceeds a second fan speed by a range of approximately 5% to 19%.
11. The apparatus of claim 1 wherein the controller varies a speed configuration of the first and second fans to determine which speed configuration minimizes power consumption while maintaining a desired temperature of an electronic component.
12. The apparatus of claim 1 wherein the controller controls the first and second fans based on a monitored temperature associated with an electronic component and a monitored power consumption for each of the first and second fans.
