Hardware

  • PXI Chassis
  • PXI Slot Blocker Kit

Issue Details

I have concerns about heat for my PXI chassis. Will the system run cooler with the PXI slot blockers in or out?

Solution

Using slot blockers improves the cooling of the PXI chassis, and it is best practice to always use NI PXI Slot Blockers in unused slots.

Additional Information

Using the slot blockers directs airflow from unused, cooler slots to populated slots which improves the cooling of the device. 

If you are still concerned about your device staying cool, please consult How Do I Stop My PXI Chassis From Overheating?​
