Try the free Speccy - do a google search.  There are several other free temperature monitoring programs and they all return different readings.  Speccy seems to be more in line with the Intel supplied monitor for my Intel motherboard. Best suggestion, whether in a warm climate or not is to locate the PC where it can get adeqate air flow.  A PC desk compartment is usually not a good location.  Same way directly on the floor and in the cleanest environment it can still collect a lot of dust.   (I live in warmer Florida).
Hello,  just recently bought a Dell Vostro 230 desktop, and living in L.A. where it gets kinda warm, I was wondering if there is a recommended software utility that can read the computer's internal temperature   Thanks Steve
