The fan may not come on until a high temp is sensed. High load does not always mean immediate high temp. Get an infrared temp sensor gun to measure laptop temp as it comes onto full load and leave it running and see if temp continues to climb. If temp climbs and stabilizes then 3 fans may be enough. Find out what the max operating temp is and measure to see if you are approaching that level.

If you are still not satisfied swap the fan with one that is running and see if the pattern continues.

You are right to be concerned because high heat will shorten the life of your electronics, but you need actual temp measurements to make a proper evaluation.
