Some larger refrigeration units have fans, but typical domestic ones usually do not, only inside the fridge/freezer compartment as such, and is used to force cold air inside the unit to help keep the contents cold.
As for the fire risk, anything electrical usually have a certain amount of risk as far as fire hazards are concerned, but certainly a lot lower then say an electrical heating element or similar device.
The noises you describe usually come from the pump itself, and i can not say if your particular fridge would have any type of fan on it not knowing the model, makes it very difficult to give any sort of prognosis - based on specific models and their typical faults/noises.
Unplugging the fridge simply stops the pump, and the noise usually returns in a minute or two as you have described, simply because the fault/noise is still there.
Pumps and repair work can be expensive, especially if the fridge is an older model and based on the average that most electrical units have a typical lifespan of 1 - 5 years depending on the quality of manufacture.
Look at it this way, a good basic unit costs anywhere from $800 - $1,500 and some of the more expensive models start from around $1,800 + ( Prices are based on Australian models and are quoted in Australian dollars )
Ok so lets break this down a little, i buy a new fridge for $1,000 and it lasts approximately 5 years, this is not expensive if you look at the cost per year which is approximately $200 / year.
Compared to the cost of repairs, typical service has a call out fee, plus parts and labor which can run into literally 100's of dollars. I guess what i am saying here is, they do wear out in time, due to fair wear and tear, and planning to buy a newer one every few years, is not such a bad idea - considering when you weigh up the possibilities of having purchased a device that can keep food cold for up to 5 years ( and in some cases longer ) for around $200 / year, planned replacement models make sense in the long run. A good way to know, is by looking at the warranty and plan to have a newer one to replace it within 12 months of the warranty's expiration, with the added bonus, you can now plan to sell the one you currently have for a few hundred dollars to help with the cost of getting a replacement.
Trust this helps you out a little, and please take the time to rate this answer, thank you.
