be quiet! MC1

Pros

• If your motherboard does not already have a heatsink, add a third-party one like the Arctic M2 Pro, Thermalright TR-M.2 2280 Type A, or Be Quiet MC1.
• Get the Patriot P400 Lite or Crucial P510; if your unknown motherboard does not have an M.2 heatsink, add a third-party one like the Arctic M2 Pro, Thermalright TR-M.2 2280 Type A, or be quiet MC1.
• A "high-end gaming PC" should have a motherboard with an M.2 heatsink. If not, you can a third-party one like the Arctic M2 Pro, Thermalright TR-M.2 2280 Type A, or be quiet MC1.
• Double-sided coolers (e.g., Arctic M.2 Pro, Thermalright TR-M.2 2280 Type A, be quiet MC1) have just some thin metal on the underside.

Cons

• the bequiets do look much more sleek and probably feel like it too but these coolers are very small no matter how they look in the pictures. i just couldnt justify spending 2x on passive cooling from the bequiets even if its 15 bucks lol.
