Default Cooling fan question

So i noticed the Others day that my Car is running a Bit Higher cooling temps then "normaly" and the Fans Starting more often...well that's another issue i already have a cute for, but what seemed to me Strange is that If the Car reaches 95 degree C just one fan will come on and cool the car down to 90 degree C and then shut my question here is, shouldn't they start at 93 degree C (as far as i Recall??!) and as far as i can tell in the past both came on once the car starts to reah this temps.

I read several threads here about one fan failing and stumbled upon the testing method with the door i'm a bit confused, as per thread you should have a low speed and high Speed test of the fans, but all the Car does is switching in the Driver side one and then the Passanger side and that's it (both have the same Speed i would say from listening). Is this OK????

I thought they both came on at the same time.

Can you run the car and put a volt meter on the fan that isn't coming on to determine if it's getting power when the other fan turns on?

Looks like everything you need to test is in this thread here.
