Unless you have dust problems or a big requirement to avoid moving parts that you can't mitigate by just having more fans than the minimum requirement, fanless might well not be necessary, a low airflow fan can be pretty quiet and will make a huge difference to cooling compared to no fan. (BTW another thing to watch out for with fanless machines; in some cases the machine is fanless but there's a separate PSU which is not!)
