Why Seal Unused PCI Slots?

Open expansion slots can significantly disrupt airflow inside your PC case, causing components to run hotter and accumulate dust faster. Sealing unused slots with these metal blanking plates helps maintain a controlled airflow path from intake to exhaust fans, which can improve your system's thermal performance and longevity.

Q: What size PCI cases are these slot covers compatible with?

A: These metal PCI slot blanking plates measure 8 × 1.8 cm and are designed to fit standard ATX and mATX desktop PC cases with full-size PCI expansion slot openings. Always measure your case's slot dimensions before purchasing to confirm fitment.

Q: Do the PCI slot covers come with screws?

A: Yes! Each pack of 5 silver PCI blanking plates includes mounting screws, so you have everything you need for a secure installation right out of the box.

Q: Why should I use PCI slot blanking plates instead of leaving the slots open?
