RB 850Gx2 Fan PINS

Fri Jun 24, 2016 2:21 pm

Hi all,

there is also a way to connect a 2pin fan to a 850Gx2 like there is on the 450G?

Thank You

JP1 is not populated http://img.routerboard.com/mimg/991_l.jpg

Are you suggesting manually soldering the 2 pins?

yes, JP1 is where FAN can be connected. That is 5V  MAX 0.15A. Make sure not to exceed MAX current.

I am asking again just to make sure. You mean manually soldering those two pins?
The pins header is not populated.

If yes, does that violate the warranty of the board?

So you cannot connect a fan to JP1.

On one post you say one thing, on other post you say another. :?

we cannot guarantee that user will not destroy the device by soldering. And then, the user cannot exceed the electrical limitations of the port or it can damage the circuit.

Little drilled hole with tiny screw can hold a contact too. And without the soldering...

I have about 5 mikrotik devices broken in about 10 years. Out of waranty. Who cares about mikrotik waranty if their devices doesn't brake?

Hello,

At my local supplier I found "Sunon Maglev MC17080V1". 5V, 17x17x8mm, but 160mA. Max allowed is 150mA, so could 10mA make some damage?

Anyway I am soldering in routerboards too if necessary. Never broke a piece by that.

Add a small resistor and you can use the 160mA fan safely ...

How the resistor could multiply the current to run such powerful fan?

It can not multiply the current, but it can limit it. The fan will operate with somewhat reduced speed, but the board's circuits will be safe.

Sunon Maglev MC17080V1 uses proprietary MagLev/VapoBearing, that supposed to be better in terms of resources, but not really time-tested.
so far i would sitck with ball bearings thus. eg "Sunon Maglev MC17080B1 model for example. also Maglev fans are "High Airflow" fans which would be kinda overkill for tiny/small devices.
for servers or say CCR it was more interesting thing.

The smallest fan i can find is pi-fan its .20A

Please advise

Its bloody hot here

Was 41 degrees celsius yesterday

And rb board is nearly hitting 60 degree

I believe with small fan i can get it down to 50 degrees

No need to afraid. It was stated that mikrotik devices should be working as designed even in 60 degrees of ambient temperature.
