Temp2 is probably your CPU temp. My temp = 127 no problem there.
The only worrying temp you have is for HD0 = 173 ? .
Make sure your HD has plenty of space around it, to allow cool air to get to it.
Most PC's only have 2 monitored fans.
1. CPU.
2. Case fan.
You probably don't have a 3rd fan connected to your motherboard.
If you have a fan which is powered by one of the PSU connectors, it probably is not monitored because it is on all the time.
Only fans connected to the motherboard are usually monitored and controlled.
If HD0 keeps getting hot you might think about getting a HD fan.
My temps are.
MY "local temp" and "remote temp" are measured by my display card.
It has its own temp warning system which shows the temperature to be low.
It only gets worried when the temp gets up to 140.
