I purchased this card since my old 3ware RAID card didn't have UEFI support. This card works in my UEFI system and I'm happy with its performance. I'm disappointed though that an LSI MegaRAID card can be so hot and is designed with such an underperforming heatsink (the comments about being designed for a server environment are BS). So much for the MegaRAID brand. It's disappointing that a big brand like Broadcom doesn't give a ... about the internet big full of the 9361 cards overheating and doesn't provide at least a copper replacement heatsink.
