Two-wire fans can be detected just as well as three-wire ones, if you measure current draw :) In fact, some chips (like the lm75) can actually COUNT ticks on two-wire fans by measuring spikes in the current draw... If you detect fan presence using ticks, you will never detect a stuck fan on startup, which is *dangerous* as it could cause the software inhibit an alarm on that fan. -- "One disk to rule them all, One disk to find them.
