Card-based extension cooling

1. An information handling system comprising:

a power supply unit;

a circuit board that includes a plurality of expansion slots;

a cooling card coupled to at least one of the plurality of expansion slots; and

a processor coupled to the circuit board, wherein the processor includes a heat exchanger coupled thereto, and wherein the cooling card does not comprise the processor;

wherein the cooling card includes:

a fan on a heatsink configured to transfer heat away from the information handling system;

a fluid channel thermally coupled to the heatsink, the fluid channel being fluidically coupled to the heat exchanger via a pump;

a power connector configured to couple to the power supply unit; and

an edge connector configured to mechanically couple to the at least one of the plurality of expansion slots, wherein the edge connector does not include electrical contacts thereon;

wherein the fan and the pump are configured to receive power via the power connector.

2. The information handling system of claim 1 , wherein the cooling card is a Peripheral Component Interconnect Express (PCIe) card.

3. The information handling system of claim 2 , wherein the cooling card is a double-width PCIe card.

4. The information handling system of claim 1 , wherein the cooling card does not include any processors.

5. The information handling system of claim 1 , wherein the circuit board is a motherboard.

6. The information handling system of claim 1 , wherein the processor is a circuit selected from the group consisting of central processing units (CPUs) and graphics processing units (GPUs).

7. The information handling system of claim 1 , wherein the information handling system includes another information handling resource having another heat exchanger, and wherein the fluid channel is fluidically coupled to the another heat exchanger.

8. A method comprising:

coupling a cooling card that includes a fan on a heatsink configured to transfer heat away from an information handling system to an expansion slot of a circuit board of the information handling system, wherein the cooling card includes an edge connector that mechanically couples to the expansion slot, and wherein the edge connector does not include electrical contacts thereon, wherein the circuit board includes a processor, wherein the cooling card does not comprise the processor, and wherein the processor includes a heat exchanger;

fluidically coupling a fluid channel of the heatsink to the heat exchanger via a pump; and

providing power to the fan and the pump from a power supply unit of the information handling system via a power connector of the cooling card.

9. The method of claim 8 , wherein the fluidically coupling includes coupling via at least one quick-connect fluid fitting.

10. An apparatus comprising:

a cooling card configured to be accepted by an expansion slot of an information handling system, wherein the information handling system includes a power supply unit and a motherboard having a processor thereon, wherein the cooling card does not comprise the processor;

wherein the cooling card includes:

an edge connector configured to mechanically couple to the expansion slot, wherein the edge connector does not include electrical contacts thereon;

a fan on a heatsink configured to transfer heat away from the information handling system;

a fluid channel thermally coupled to the heatsink, the fluid channel being fluidically coupled, via a pump, to a heat exchanger that is configured to couple to the processor; and

a power connector configured to couple to the power supply unit;

wherein the fan and the pump are configured to receive power via the power connector.

11. The apparatus of claim 10 , wherein the cooling card does not include any integrated circuits.

12. The apparatus of claim 10 , wherein the cooling card does not include a second processor.
