Slip Stream 1900Rpm

[stealth]

Hi everyone

Scythe Slip Stream fan on my computer I'm using a trademark.
Technical specifications:
1900 Rpm
0.53A

I've used other brands fan Silverstone Fm121's technical features:
Rated Current: 0.40A (Max: 0.50A)
Rated Power: 4.80W (Max: 6.00W)

This maximum value on the Silverstone brand of fan is?
Of its own power for a fan can draw more current?
Scythe Slip Stream current in the same feature?
So the maximum power values Scythe fan is the brand?

See you soon.
