Does the XGS1250-12 have/use active cooling?

Hello,

you can also mount the switch vertically, the port side being vertical.

The switch temperature is now naturally much lower, no heat sink or fan added.
The environment where it is mounted is quite clean.
With the heat exhausted by the switch, I barely doubt dust coming in…

Being happy with this setup, I just wanted to share.

from the datasheet it say it got a fan

Thanks for the replies everyone but this thread was answered early this year. The 1250 does have a fan, the v1 firmware was … let's say, "not the best", and the v2.00(ABWE.0)C0 firmware solved most of the thermal issues although I'm waiting patiently for some refinements in the next firmware release. For what it's worth though, all 4 switches have been stable and efficient, keeping up with a fairly heavily loaded Arista DCS-7010T-48 in each of the home data center, the real data center, and at the day job for about 9 months now. The WAX650S APs are really solid, and the next deep dive will be into the XS1930-12HP and XS1930-10. The current round of Zyxel designs appear to be solid and perform well. Thank you, Zyxel!

Unfortunately this switch has very ineffectual heat dissipation design. There is a metal plate inside of switch mounted on several stands and this plate contacts with hot chips through the thermal pads about 3-4mm thick. This metal plate has no either ribbing for better heat dissipation or any contact with switch's top case cover. Existing fan mounted right under this metal plate and I don't understand how it can effectively cool this plate ! I use 10G ports and switch gets very hot and frequently turn on the fan. Fan is noisy enough and I decided try to make the switch silent by adding cuprum plate 50mm x 200mm x 2,5mm + couple thermal pads 50x200x0,5 on top of existing metal plate. Overall thickness between factory plate and top cover is about 3,5mm. Thus through this sandwich heat dissipates directly on top cover of metal switch case. I already test the switch for several hours and didn't hear the FAN all this time. Now switch case much hotter then before. Its external look didn't change and there is no tons of different creepy heatsinks on top of case.

Hi @DeGlucker,

I would like to share with you:

Our product design must comply with regulations across various countries, which requires controlling the product's surface temperature. Therefore, we have added a fan to meet the chipset's heat dissipation needs. We have also considered noise concerns and implemented the smart FAN control system.

If you still find the noise level unsatisfactory and choose to modify the equipment to enhance cooling performance, we must remind you to prioritize safety, avoid burns, and ensure that foreign objects do not enter the device, as this could lead to short circuits and damage.

If children are at home, remember to place the device out of their reach or consider adding a protective cover.

Yes, you are right. Silent device is priority number one for me. And I think passive cooling could be better thought out. For example, look at Mikrotik RB5009
