Product Description & Info
Made especially for Dell PCs and previously unavailable at reasonable prices,
Sidewinder Computers has acquired this special thermal controlled 92x32mm fan
made by NMB. Each 3612KL-04W-B66 has an integrated blue thermistor at the fan
hub and helps eliminate unnecessary dangling wires in your case. As the
temperatures it detects increase, the 3612KL's RPM will raise to compensate and
dissipate unwanted heat from your PC. Other Dell PC owners have already
discovered this little gem and saved themselves time and money by sourcing
Sidewinder for this product.
