The max rpm is: 2200@ 2200rpm the fan delivers ~ 32 CFM and has 17.7 dB(A)As this fan uses PWM function the min rpm is 450rpm.There is a speed adapter in the scope of delivery in case you like to drop the max rpm. In this case the max rpm would be 1750rpm.

What connector does this have? Nothing listed or shown.

PWM implies 4-pin and indeed it has a 4 pin connector

I'm running an older dell i7 3770. 77 watt. this fan is the same size as my cpu fan. i have an adapter to go from the mb to a pwm fan. will this work?

Most Dell systems use a proprietary 5-pin fan header. In order to make it work you'll either have to modify this header or buy a special adapter to make it work with Dell motherboards

Does it come with Molex adapter / Can I connect it to the power supply instead of to the mother board ?

You can connect it directly to the power supply. It doesn't come with a MOLEX adapter and I'd just pick up a generic one here on Amazon instead of opting for a dedicated 3 or 2 pin fan. Here's why: Today you may want to run it directly off the Power Supply, but down the road you may want to connect it to a 4-pin fan header and then you'll have to buy another fan if you opt for a dedicated 3 pin or 2 pin fan now
