Recommend? Sure, good program? No.

The only temp program I've ever had much confidence in was Asus PC Probe way back when it was an old simple version rather than whatever the mess they have now is, and you sort of need an Asus board for that.

Speedfan seems to be a popular recommendation, and I'll admit I've used it, but I've never felt very confident in its results. And if you don't use some critical thinking you'll see what it reports and get paranoid and post back here asking if your system is really running at 125C.

You can run components very hot, and while that may shorten their life span, you are shortening it from something like 10 years down to 5-7, and chances are you won't even be using those components in 3. So I wouldn't worry about temps at all unless you are expierincing issues with stability.
