[BPI-R4] Replacing sinovoip FAN from heatsink

[Xiaomi_ax3600]

Good evening, I have received the 2 Noctua NF-A4x10, the temperatures on the 10gb have dropped a little but only a few degrees. and with the lid open.

10gb WAN input direct from the operator is 71,4 degrees

2.5gb input from the switch to the WAN the temperature is 50 degrees.

the speeds are correct, both 10gb and 2.5gb input, having a 2.5gb card in the pc

this is the other banana pi that I have assembled today,

the temperatures in the other banana pi was 75 degrees in 10gb wan, in that one I only had a heatsink bought on aliexpress that was for banana pi r4

do you have a 10gb line contracted with your internet provider?

If I put the 10gb line to the 2 bananas I have, it shoots up to over 70 degrees in both, it doesn’t matter if I have the noctua or the heatsink installed.

If I put a 2.5gb line to the wan, they stay between 50 and 52 degrees.

If I put a 1gb line to the wan, it stays at 40 degrees.

I hope for your help and that you enjoy your vacation.

do not remove the heatsinks from the sfp ports when using the fan. do you use the noctua blowing on the sfp or does it suck from the sfp ports? I never had problems with the 10gbit sfp line from my provider, the only problem i had was with the sfp-rj45-adapter. not sure which heatsinks you use but it should never go over 70°C - is this aluminium or copper? where did you buy them?

Good evening, I bought them from the SinoVoip Co.,Limited Banana PI store on Aliexpress:

and I bought the heatsinks here, which said they were for the banana pi r4.

I have tried the first banana I had with a heatsink and I have mounted another one today without a heatsink and the maximum temperatures reached were 75 degrees or so in both, both in the one that had a heatsink and the one that didn’t have a heatsink.

You mean to tell me that the problem is with the sfp+rj45 in the 2 I bought.

Let me know.

[oli]

its too many variables that can lead to this. i am not sure but iirc i have my fans sucking, not blowing mounted. tbh i am very unhappy with the other stuff from sinovoip so i bought those heatsinks that were mentioned here, cant check now coz i dont have access to aliexpress right now. paste exact information about the sfp adapters you have problems with.

Good morning, I’m leaving you the version of the sfp+rj45 via uart, with a 2.5gb input to both wan and land as the PC card is 2.5gb

I bought the 2 sfp+rj45 on the official page

SinoVoip Co.,Limited Banana PI

The temperatures of the rest are all perfect, but if I put the 10gb line that I have contracted to give it internet, then the temperature shoots up in the sfp+ I’ve changed them from one side to the other in the same banana, I’ve also tried them in the second banana that I bought.

I don’t know if the image version that I have in my banana is wrong because of whatever the sensor is.

But now I’m not clear with the downloads of the new my images, they give me telnet and ssh, but there’s no luci and I can’t enter through the web to be able to download the sensor.

They are tested with 4 sources of food, if that were their problem.

65W tipo C, 20V, 3.25A,

19V, 3.42A, 65W

65W USB C provides a high power output of 3.25

12V 2.5 DC who bought with the first banana

Maybe if you tell me how to download the new images I can try it again, or if you send me your image I can do the test.

Thanks for your help.

i cant send you my image because it contains my configuration. i cant reproduce the problems you have.

When i do a stress test it does not go beyond 50°C - thats the sfp-rj45 port. the sfp-wan port is much much cooler:

Maybe its the sfp-modules you use, not sure tho.

i have those heatsinks: https://de.aliexpress.com/item/1005004248744480.html?spm=a2g0o.order_list.order_list_main.10.1e775c5fnSDNp1&gatewayAdapt=glo2deu thats the sfp-rj45 modul i use, but it gets very hot and even stops working without fan and heatsink: https://de.aliexpress.com/item/1005005657528370.html?spm=a2g0o.order_list.order_list_main.40.1e775c5fnSDNp1&gatewayAdapt=glo2deu
