Replacement for dying X8DT6-F if i don't need on board SAS?

My SM MB is having issues and needs to be replaced.

What’s a good dual socket board i can get for dual L5640s? I’m pairing down the amount of drives so i don’t need the on board controller.

Supermicro X8DTL

Any iteration in particular?

I see there are a few models.

Also - it looks like that board has a lot of chipset heat issues. If it’s going in a tower case how should I best address that?
