NMB 80x25mm Thermistor Fan, 25CFM, 3pin RPM
Product Description
NMB 3110KL-04W-B66
This fan is a best buy for any computer... Made by well known quality fan maker NMB Minebea (who now makes Panaflo's for Panasonic). These are used in Dell's and you will find them selling around the net as "Dell" for an utterly ludicrous $24-$94.79+. This fan has a fairly short ~7.25" twisted tail ending with the flat type 3 pin connector. Just make sure you properly orient it when plugging it in.
This is a temperature controlled thermistor fan (blue thermistor in picture).
I can't find accurate CFM specs for it's range but it starts at 25CFM with a noise range of 22-40 dBA and a rated draw of .34amps.
As a replacement part it is used in DELL OptiPlex GN, OptiPlex GX1, OptiPlex GX110, OptiPlex GX1P, OptiPlex GXA, OptiPlex GXPRO and possibly others. The Dell part number is identical to the NMB number.
