Do you have a concern about the fan, or was your question 'interest only'?
I think that you will find that most folk here run the custom firmware with the fan package, which keeps the fan running all the time at lower revs. The benefits of this is that the HDD runs cooler and more temperature stable, so does not reach the temp at which the Humax switches it on to full revs causing it to be pretty noisy. I run mine at 50% which keeps the HDD at or below about 40C.
I have just replaced the HDD which was beginning to fail, probably not helped by the large temperature cycling. I have now also installed the "fan" package and set the minimum duty cycle to 34%. This keeps the drive at 50C, but I do have a concern over the life of the fan when running continuously. The 34% was chosen as a compromise between HDD temp and fan speed. Fan life is dependant upon speed and temperature. Also, of course, noise is also a function of fan speed.
So the Nidec fan is likely to be slower, move less air, but be less noisy than the Delta. My Humax was quite an early sample, so did Humax change the fan to improve cooling? It may also explain why some owners complain about fan noise and some don't.
