Got surprise - after CRS310 worked in vertical state (it is allowed state due to we have corresponding wall mount holes on the case) I heard that fan started work much noisier even if no any traffic load. Opened the case and saw this :frowning: : https://ibb.co/PQS5fYq Question 1 to Mikrotik team …

Question 2. Fan connector in the front of fan… it is weird That isn’t a question.. What is weird about it? Standard 4-pin fan power connection. One pin is ground, one pin is power, one pin controls the speed, and one pin reports the speed.

BTW after my fix my router looks like: https://ibb.co/n7r6QXv i.e. I used special double side scotch for heatsinks Yes, I made “support leg” using thick scotch like Mikrotik’s do due to no choice, you can see it. I replaced original plate pin heat sink with square pin one with about same area. W…

Thanks! I thought I was the only one with this problem. I suspect half of all CRS310-8G+2S+ has this failure. Out of the 12 switches I had, 6 had the issue, and the rest is just waiting to fail. MikroTik has been totally silent about it, and RMA’s running since the start of June has not been answe…

Question 1 to Mikrotik team - may be use more robust heatsink mounting instead double-sided scotch tapes which cannot hold good ??? I’m really surprised that thermal epoxy wasn’t used in this case. Question 2. Fan connector in the front of fan… it is weird It’s standard 4-pin PWM con…

It’s standard 4-pin PWM connector, you’ll find it in modern PCs too. Before answering randomly, it would be better to read the previous posts first. It has already been written (on post #2 !!!), and already badly interpreted. It is very OBVIOUS that it refers to the CAP that forms the connect…

Just wondering : could a free flying heatsink cause a short-circuit / be a fire hazard? If so they might be at risk of getting this device pulled from the market.. Or am i just talking bs here? In any case i am going to hold off a new purchase until this is fixed (vertical mount is required for me…

[PushPinHS.PNG] A couple of extra holes on the PCB and 2x Push Pins would solve this problem.

Yes - using 2 extra holes and a push pin solves the issues. The current issues are clearly a design fault. Seems MT used a PCB design bureau that does not have that much experience in this area given the design mistakes (heatsink, fan connector, fan noise). i rather pay 10-15 euro’s more and have th…

This is what i got - a heatsink camping on top of the capacitor. See
