3 pin mobo connectors?

[2uantuM]

I'm thinking about rigging up the fans on the front of my case to run off the 3 pin fan connector and using speedfan to dynamically change the speeds. What's the maximum current that the motherboard can handle? I checked the manual put I didn't see anything. The motherboard is a MSI Neo4 Plat

I'd like to know the answer to this myself! I know back in the PII/PIII era, it was really easy to blow out a fan header...
