Does the XGS1250-12 have/use active cooling?

jamestk · May 2025

i've had to RMA two XGS1250-12 units and currently on my thrid, the previous ones just cooked themselves to the point where the 10G Ethernet ports just stopped working, there seems to be a serious design flaw on these, i've had to put an 80mm 5v fan at one end to blow air across the until just to keep it cool.

I just ordered this and had not seen this thread. I am definitely planning to populate all 3 of the 10Gbe ports. Instead of a giant copper plate maybe a few copper pennies with thermal pads placed right above where the underlying hot chips are would work as well? I may try that.

I just ordered one and I had not seen this thread. I am planning to use all 3 of the 10Gbe ports. Should I be preempting the cooling? I don't have any copper plates but I do have a lot of pennies and thermal pads. So theoretically I could strategically place the pennies above any hotspots on the existing plate to transfer some heat to the case.

I ended up doing exactly this, I placed 5 pennies right above where the 10G port chip is. I put 0.5mm tape above and below each penny. Since they are copper, they seem to transfer a lot of heat to the exterior of the case. I also placed an old CPU heatsink with heat pipes on top of that same spot on the exterior. It seems to get quite warm so the heat is transferring through conduction well it seems. I originally had a smaller heatsink and that got quite warm, the later one is rather large and it seems to dissipate the heat well.
