Well, Having NO fans in your case is a bad thing really. Without proper circulation your parts are going to be hurting in the future. Having the side of your case open 24/7 really isnt too great either, it is leaving your computer too exposed to the elements.
I believe that Temp 1 is your system/motherboard which is okay - Temp 2 is your CPU temp which is way to hot on any cpu.. I dont think I have ever seen my CPU go over 40c max on full load.
It seems like circulation is your biggest problem now...This may sound weird but for testing purposes, do you happen to have a medium to large fan that you can stick in front of your computer? If you do.. Put it on the side of your computer, with the case open, and let it run for a while(pushing cool air into your open side), then look at the temperatures again.. Take a screenshot of speedfan again. If your temperatures go down, then your problem is indeed circulation.
What are your system specs? Also what kind of case do you have?
