Pro Pioneer fan failed (?)
Hello! I have a ReadyNAS Pro Pioneer Edition 6-bay NAS device, about 4.5 years old. Running constantly without any major probems (once, however, I had to move all data off and reformat the system d...
You definitely want 4-pin PWM fans, or they are going to run full speed all the time. Also the "3-pin to 4-pin adapter" that those come with is, I believe, an adapter to a 4-pin disk drive style Molex connector.
I replaced a CPU fan with an Evercool EC8015HH12BP. It has fewer, but larger blades than the original and thus runs quieter and at a lower pitch. The max airflow is a little less than the original, but I've never seen it running at full speed except during a boot, so it shouldn't need it. A Delta EF0812DB is another option with a little higher airflow spec than the original, but it has even more and smaller blades. Mine didn't fail completely, but the bearing was getting noisy and it was just a matter of time.
The power supply fan is certainly replaceable if it should fail, but I wouldn't suggest doing so just because you can. It doesn't seem to be a big noise contributor. I had a supply fail and pulled the fan from the old one just in case I need it in the future. It is just a two-wire "dumb" fan.
I have always found the CPU temperature to be rather low and have wondered if the two temperatures are reported backwards. My CPU temp is always reported lower than the case temp, which seems odd. When my drives are spun down, I have had the CPU temperature reported at or even a little below ambient room temperature. I highly doubt that to be the case. I can easier believe that of the case temperature, the slightly below just being lack of calibration.
