Ferm. temp on Beer smith vs White labs

[Rhinocook]

So I've just brewed my first brew with a yeast starter and using Beer Smith software. One thing I noticed is that Beersmith said to ferment at 67 yet on the Whites labs bottle it said 70. Which should I do? Beersmith has all the parameters of my specific system and the beer itself, but White Labs knows their yeast!
Like I said, I made a starter on my stir plate over about 20 hours. Would love to hear some peoples thoughts on this one. It has been 4 days and fermentation seems to have slowed right down.

Every vial says the same thing(with the exception of lager yeasts). Go to their site and find your yeast. It will tell you the specific temperature range for that yeast.

What Weizer said, FWIW 70 is too hot for almost all yeasts unless your doing a Saison....most of your standard Ale yeasts will want 62-65 to be happiest.

You set your own temps in Beersmith. It comes defaulted but you set up your own fermentation temps/times/vessels/etc.

And 70* isn't too hot for ales. It is probably too hot during propagation but after that, crank it up. I generally start my ale temps at 67*F. After 24hr I'll bump it to 69*, then 71*, then 72* and leave it there for the rest of fermentation. Last two batches using US-05 this way I'm averaging over 83% attenuation. I was averaging around 76% when I ran fermentation cooler the whole time.
