nicecity host: fan replacement
The fan of the CPU heat sink of the nicecity host died (the fan was stuck). It was a cooler master 40mm fan with 3 pins (something like the A4010-70RB-3QN-F1 model).
I replaced it by the original fan provided with the Gigabyte D525TUD motherboard but this model is really noisy (that's why it was replaced in the first time).
Then I replaced the original fan by a Noctua NF-A4x10 FLX. The fan is very quiet.Here are some photographs:
