An air baffle assembly for air cooling in computer systems is described. The air baffle assembly can include a baffle body removably installed on a printed circuit assembly deployed on a chassis. The baffle body can cover memory components. The air baffle assembly can also include an air dam removably installed on the baffle body. The baffle body has a slot positioned on a side of the baffle body, which can be substantially parallel to a wall of the chassis. The baffle body can further include alignment rails positioned in the slot to guide installation of the air dam into the slot. The installed air dam can reduce a bypass region, thereby reducing airflow through the bypass region and increasing airflow through the memory components.

Removable air dams for air cooling in computer systems

A micro control unit ('MCU') controls operation of a cooling fan in a compute device. The MCU is responsive to determining that a fan speed of the cooling fan is above a predetermined speed threshold to periodically determine power consumption of the cooling fan. In response to a periodic determination of power consumption exceeding a predetermined power consumption limit, the MCU reduces the fan speed of the cooling fan by a predetermined increment and continues periodically determine power consumption of the cooling fan. Upon determining that the power consumption does not exceed the predetermined power consumption limit, the MCU discontinues any prior reduction of the fan speed.

System and method for compute system cooling fan control

An apparatus can include a fan including a control pin. The fan may receive a pulse width modulated (PWM) signal at the control pin. The fan may further control a speed of the fan based on a duty cycle of the PWM signal when the PWM signal is in a first range and, responsive to the duty cycle of the PWM signal being in a second range, transmit information corresponding to the fan to an external controller.

Examples herein relate to an adjustment of a power limit of a processor. Examples disclose setting the power limit of the processor. The examples also obtaining a temperature difference between a die temperature of a core within the processor and a throttle temperature. In response to a determination that the temperature difference is at most equal to a temperature activation point, adjusting the power limit of the processor so that the adjust power limit is less than the set power limit.

Adjusting a power limit in response to a temperature difference

An electronic module enclosure has a frame with an airflow opening. A gate positioned within airflow opening pivots between open and closed positions, allowing a maximum and minimum amount of airflow, respectively, through the airflow opening.

A system and method for connecting electrical components. More specifically, a method includes positioning a first set of electrical contacts of a first device opposite from a second set of electrical contacts of a second device, and activating a mechanism configured to rotate the first set of electrical contacts between an engaged position against the second set of electrical contacts and a disengaged position offset from the second set of electrical contacts.

System and method for connecting electronic components

A system and method for managing electric cables. A cable arm is utilized to contain cables running to an electronic device. The cable arm having a mounting bracket that enables movement between at least two vertical positions relative to a base bracket is thus selectively moveable between a plurality of positions to permit access to the electronic device.

Drop down cable arm

According to one embodiment, the present invention includes a first electrical connector located on a computer component and a biasing mechanism having a leverage member, such that actuation of the leverage member biases the first electrical connector between engaged and disengaged positions with respect to a second electrical connector separate from the computer component.
