What does an open clutch cover bring?

Hello. I bought a ducati Monster 1100 2 weeks ago and wanted to convert it now over the winter. On the internet I have seen dozens of different open clutch covers. But why? will the standard clutch be too hot during a slightly more aggressive ride? Besides, I have read that an open clutch lid the clacking so this ducati typical noise some have amplified. I hope here someone knows the purely optically I like the open en lid very good and I was happy to get one but just not who the engine could take harm
