just sorted it for youWho bought all the black ones?It says on pre-order now. I managed to get hold of one, but had planned to get two...
Well spotted yes 5Vdc is used, with loads no more than 500W.Is the Noctua fan you use to replace the stock fan the 5V or 12V model? In the fan swap guide it says 5V on it but the stock fan is 12V...?
The fan voltage mapping of ENP-7660B means it sits at around 3Vdc to around 480W. So a 12V noc would not spin up at all until thermals reach a point where it comes on
it shortens the fan life. takes about 1-2 months, according to Noctua, ie if you were to run it at 12V constantly.What happens to the 5V Noctua when load goes above 480W though? Will it not break when the voltage goes too much above its rated voltage?
No, it doesn't apply more or less. It depends on the fan control circuit and it's function / mapping. The PSU you have looks a particularly old circuit design >10-15 years and is fairly inefficient. That results in higher thermal losses.Does this apply to (more or less) any flex PSU? I have an Argus 250W PSU that only powers a 11400/MB/RAM. Would you also recommend a 5V Noctua fan for this one?
Safety is your responsibility, should you be in any doubt seek a professional for the following.Measure your fan header voltage with ps on taken active low@Overtek are you still selling these custom 2 pin black Noctuas? Or even the cream ones.
I did fan swap on my ENP 7660B since it was sounding mini jet using the adapter Noctua provides with the fan but after maybe a week I did notice that PSU runs very hot and the fan was not spinning. I think my total system consumption should not be more than 180W.
After taking the Noctua fan out it was a little bit smelly, but so was the PSU. Luckily it still works. I used 5V 3pin version and with included Omni Join adapter made it 2 pin. It was spinning in after i boot the system but must have stopped after a while. Noticed approx after a week.
So I would like to try yours fan made with more professional care since I am not really satisfied by the Adda fan the ENP has. Sadly while playing Cypberunk it is almost as loud as GPU fan or maybe even more.
Thanks
