Hi,
When i’m using a 4g USB key (Huawei E3372h-320) on my Beryl AX, it became VERY hot after some time.
Even if i’m using it as back up (Failover mode with first repeater, then Tethering), it is still very hot.
When i’m using it on my MangoV2, it is warm ,but not hot like with the Beryl AX.
Hi
The Beryl AX operates at a higher temperature compared to the Mango V2, so some of the heat may be transferring to the 4G USB modem.
If the temperatures remain within the normal operating range, there’s no need for concern.
Alternatively, you can lower the temperature threshold that triggers the Beryl AX’s fan.
Please note, however, that this may lead to increased fan wear over time.
Hi, thank you for your answer.
Actually, the Beryl itself is not overheating—only the USB key gets hot.
It feels like too much voltage (or current) is being delivered to the key, but I’m not an expert, so I might be mistaken.
May we know have you actually measured the temperature using a thermal imaging camera or sensor?
Touching it is usually not accurate enough, because human perception of temperature is relative—it depends on the temperature difference between surfaces and the thermal conductivity of materials—rather than an absolute value.
If the USB key still functions normally, it's unlikely to be a significant voltage upgrade issue, as such devices typically don't support wide voltage inputs.
But anyway, as mentioned earlier, if the temperatures remain within the normal operating range, there’s no need for concern.
Yes it was just by touching. I will try to get something to mesure it.
But the difference is big between when plugged on the Mango or BerylAX. I’m now scared of letting the key on the BerylAX for a long time.
I tried to reproduce it, but this time the key was at normal temperature. I’m not sure what happened last time.
