CPU temp monitoring

Not sure if this is the right forum, but here's the situation:

Roughly 10 servers running various VMWare flavors (ESX 3,4, ESXi 3,4,5). I'm looking for a way to monitor the cpu temp on the host server, and set up thresholds and alerts (email). Here is the kicker, due to budgeting constraints (ie no budget) I basically need something "free". If anyone has any ideas or recommendations that would be great.

Are the servers brand name? Dell has an openmanage app. HP has Insight manager. You could try Spiceworks and see if that works for you

The CIM provider built-in to ESX and ESXi in version 4 and 5 reports a lot of hardware data to vCenter Server, and vCenter Server has default alarms that trigger when there are temperature issues. That should all work regardless of your server vendor, and without any need for additional agents or monitoring software. You can associate actions with the alarms, such as email, SNMP, or even to place a host into maintenance mode which is great when you have a fully automated DRS cluster.
