Open the system and using a can of compressed air to blow the fins out.
Note: Do not allow the fins to spin freely while cleaning. Use a pencil or something small like this to hold the fans stationary while blowing them out. If this does not resolve the turning problem then a replacement fan is most likely needed. I found the exact model HERE for replacement.
Even more important is the Bestc mdel number ATX 1956D B2 as that seems to be the PSU. If that fan inside has stopped then try blowing it out also but in most cases I find this indicates a failing psu and replacement of the PSU is the only option. Exact replacement part found HERE

Most PSU's are secured by 4 screws on the back of the case. From there you disconnect all power connections to mobo and drives.
Take note what connections go where using a piece of tape to mark each connector where it goes and then matching the new psu connectors to their relevant spot.

Also I'm not sure but you keep saying the two fans.
The first one is the only fan you need to replace.
The second is a power supply and includes the fan inside of it.

Are you sure you have the meter set for DC and not AC?p.s. Tried to check the DC Voltage from the board to the DC Brushless fan and we were getting a reading of 120V, yet the fan motor calls for 12 volts. Is this indicative of a bigger problem?
I don't think there is any way you could get 120vac on the board. The only AC in the computer is to power the power supply. The power supply then supplies DC to the board and other components.

Hi, thanks for checking into this. We used a DC voltage meter and held the two probes to two of the three prongs (on the DC Brushless) and we would get readings of 120 - 138. Again, I am quite the newbie at this, and we wanted to make sure there was power going to the mechanism, or id it was burnt out completely. I hope this info sheds some light as to what and where we were checking... Thanks againAre you sure you have the meter set for DC and not AC?p.s.
