Print fan (MK3S/+, MINI/+) new generation weaker

Have recently bought 3 new fans for my Prusa MK3S and MINI, unfortunately had to realize that these do not approach the old Orginale Prusa fans. Have wondered why the new fans are suddenly too quiet, after some test was clear, less air flow and also less speed according to the display, the new have about 3600U/min at 100% fan speed and the old are at 4700U/min, I do not find OK from Prusa, then I could also take FYSETC fans, as these are just as weak or have less cooling capacity, especially with PLA.

Have you also had the experience?

How do I tell which fans I have?  I have used FYSETC and they worked for me.  

Have you tried Sunon or LDO?

It's not about trying it out but yeah, I've tried the FYSETC and LDO, the FYSETC are less powerful than the original Prusa fans, the LDO are more powerful, but the speed monitoring needs to be disabled.

The new Prusa fans I bought last week now have the same throughput as the FYSETC, which is why I removed the FYSETC again, after all I want the same throughput as the old Prusa fans.

I know Prusa's speed control isn't that great, but I wanted the originals again, but this time they're less powerful than the old ones from last year.

Here is a small video of the new and old Prusa fans.

new original Prusa fan:

 

old original Prusa fan:

 

The old ones are of course louder, have more throughput than the new ones, or in other words, the new ones don't have the same speed as the old ones.

Have you contacted support?  They might be able to point you where to buy the old ones or an equivalent?

I've already done it, let's see what comes out of it, just don't think it's okay that Prusa is now selling worse ones.
