Slip Stream Slim 120mm at 5V?

[x135]

Hi,
According to this topic the Slip Stream Slim 1200, 1600 and 2000 RPM Versions should spin up and run at 5V.
Now i want to know, what RPM will they have and how much watt will they need at 5V?
Thanks

I'm interested too, for example the regular Slip Stream 1900rpm @ 5V spins slower than the Slip Stream 1600rpm @ 5V.

Is it possible to roughly know the spinning speed of the Slip Stream Slim fans at 5V or at least the starting rpm? We have the starting rpm data for the regular Slip Stream fans, but I can't find this info for the Slim series.

Thank you very much.

There is also a sticky thread concerning Slims:

I've seen it, but it doesn't say anything about rpm

You can find some info when using Google.

In German but the table should be self-explanatory:

Thank you for your reply.

The strange thing of the X-bit labs reviews is that the starting voltage of the Slip Stream Slim fans is quite different from the starting voltages reported here Starting & Running Voltages of Slip Stream Slim 120 mm Fans

X-bit labs say that the 1600rpm Slip Stream Slim fan doesn't spin until 5.5V, while the pinned thread says 3.89V / 4.7V... it's a huge difference.

I am afraid you'll have to accept this as tolerance. As you can see in the Scythe table and as you quoted even the two samples used to generate the table had quite different starting voltages.

I don't have more to add to this topic I'm afraid. So if no one of Scythe staff answers here i cannot supply any more input as i don't have any samples or figures.

For me it seems as if the normal +/- 10% tolerance of all Scythe fans would spread even more in the low voltage area.

Thanks for all the infos so far.

so the 2000RPM Version should spin up at 5V?
How many amp will it need then?
This would be quite important to me, as I'm planning to power it from a USB port.
