Product Advantages
Essential for PC Assembly: This base bracket is commonly required during computer builds—it's a good idea to keep a few spares on hand.
Compatible with New Motherboards: If you're upgrading to a 10th or 12th Gen Intel motherboard, your older fan bracket may not fit.
Cost-Saving Solution: Instead of replacing the entire CPU fan, simply swap in this updated base bracket to continue using your existing fan—saving both money and resources.
