If this is the case it could be due to the fan but it may also be just due to the added electrical load. So what I would do is just jump 12 volts to the fans and turn them on with the engine off and see if they are spinning smoothly. We don't have a manual on your vehicle as it is not offered here in the USA but I suspect this is due to another issue then the fan itself. However, here are some guides that will help with this:

I suspect we have an issue with the engine even without the fans running. So we need to check and make sure we don't have any vacuum leaks or misfires, or mount issues.

If these check out ok then the last thing we need to check is the battery to make sure it is not weak. Adding more electrical load and it vibrates could indicate a weak battery.

I attached a lot of information but this is a pretty general issue so we need to start crossing things off the list and as we do, it will make the issue more clear.
