Silentwings 3 high speed pwm or normal pwm

So what is the difference and which one should i get the price is the same.

I need four for a push pull setup in my radiator and 3 for my case.

High speed has a higher maximum and minimum spinning speed.

 

You can lower the speed of the high speed fans to a point. If the minimum speed is too high for you then that can be a problem. Otherwise the high speed is a good choice if you can control the fan speed. 

For rough estimate on noise through a radiator:

so if i get he high speed pwm fans there is still a minimum?

Yeah. But 200 vs 250rpm, it's probably not going to make or break anything. As long as you can control fan speed well the high speed look like the best option.
