I do on my e46 330xi. Have been for about a year. I took it out to swap the radiator, which turned into more stuff since I broke some things and never put it back in. I monitor temps with my app and it stays between 190 and 210 on a hot day. I am planning on putting in an electric fan on it and I am sure you can do that with your 3.0.

I even let the car idle for 30 min and it never got hotter than 210.
