well you can use a program called cpu-z just tells you the temp and some more. You can use Xtu, Trottlestop, Hwinfo64, Hwinfo LogViewer, cpu-z, gpu-z and HWMonitor. There are also many other software you can use.
CPU-Z.
As long as temps are below 80c, it's perfectly fine.
chugalug btw how do i become a comp master like you are
Learn stuff, browse reviews and PSU spec/chart pages, answer sht, answer more sht and surrender yourself to the fact that no matter how many statistics you present or how much research you do that there's always going to be fanboys of certain brands that deny whatever facts you give them so they can waste their money on a 5 year old architecture because it has a higher clock speed and more cores, frustrating you beyond belief leaving you sitting there wondering why you even bother.
Then you get badges and stuff to show how much time you've wasted that you could have spent with a glass of single malt whiskey and music, gaming or doing something productive instead.
Existence is pain.
But at least it's satisfying to help people get more bang for their buck or stop them wasting their cash when it does go well.
Even though the OP has the answer I wanted to drop a TH link/guide for Intel temps which is the Intel Temperature Guide by CompuTronix. It has a ton of info and is a great read.
