not anymore, nowadays most of these taiwaneese motherboards have a temp
sensor/fan speed sensor in them. but i hav noticed that most of these can't
read the fan speed of a ppga celeron (might be becauz it uses 2 leads,
whereas the older celeron sec/pII/pIIIs 3 leads).

also a good idea is to get a couple of those cheap smps/cabinet fans which
cost abt rs.125 and are quite reliable.but note that try and get a fan with
a connector that wud go into the motherboard, then u cud monitor their
speeds too.
