Needs compatibility options
The one complaint i have is it does not have another way to power it but the 4 pin adapter. The other roswell fans black in color had the old ide power and a 3 pin connector, this fan did not. Not that big of a deal if you have the 4 pin connector like most newer pc's do but i did not have that luxury.So my minus one star is merely for a lack of compatibility. Plus the 4 back black fans that are compatible are only 14 bucks and this was 11.
