CPU Temperature Higher Than Anticipated?

Hello,

I just put in a new motherboard, CPU, and CPU cooler into my system today. The CPU, thermal compound, and cooler is what I'm concerned about. I am using a Cooler Master Hyper 212 EVO with Arctic Silver 5 High Density Polysynthetic Silver thermal compound (not the regular Arctic Silver 5). Upon looking at CPU temperatures in BIOS, I am seeing 43~45°C. I am really surprised, as I thought it would be much lower than that. Could this be because of the "break-in period" that is required for Arctic Silver 5 and other Arctic Silver pastes? If so, as the break-in period advances, will my temperature gradually reduce? If not, could it be that I put too little or too much thermal paste?
Thank you for your help!

Read the article. Check the center to make sure it isn't keeping the bracket from seating properly. There is a nub in there that has to sit down in a hole, also, there is a thumbscrew in the center that must be tightened. If you will read the entire tutorial, it's all explained.

And it should not require much effort to start the screws. You need to start one screw by about two threads, move to the one across diagonally from it and do the same, working in an X pattern. Then tighten in two or three turn process using the same pattern. If you screw one in too far, the others will be hard or impossible to get started.

The temperature in my room during this time of year is 68~70°F (with heater sometimes running; also live in south Louisiana). The motherboard temperature is usually around 30°C (~86°F) when on (just extra info). I am pretty sure I mounted the cooler correctly, though it required a good bit of pressure to get the screws from the cooler itself into the standoffs on the motherboard (normal or not?).
