• Odd Laptop Temperature issue

Right now I'm running a Sager 8130 with a i5 2520M with Speccy reporting it as 36 C idle. A bit ago I was watching a movie while defragging and my CPU temps were ~70 C I was confused to say the least. Just now I did a run of Prime95 for 5 minutes to see if my CPU temps would jump up, with all threads/cores being used 100% my temps went to 45C. I felt the back of my PC to see if it was exhausting hot air and it wasn't hot at all. Is this a broken temperature sensor? Why are my temps getting stupid high for certain tasks but not others? Also, something weird, after I stopped the defrag and watching the movie. Speccy/HW Monitor reported the temps still being up in that range while my PC was exhausting MUCH cooler air than before. ***EDIT*** Forgot to plug in my battery for the Prime 95 test. Speccy reports my CPU getting to 78 C with HW Monitor reporting 71C on Core 0 and 83C on Core 1. Temperature seems to go down after I halt the Prime 95 test. Why was it so high before?
Sometimes defragging can get pretty intensive.
Defragging is CPU and HDD intensive, you will be utilizing that quite a bit. you may want to check the vents and make sure dust isn't clogging it, blow air in it if there is.There are also programs that will set it up to a higher RPM, but laptops generally get much warmer than desktops
I put some new thermal paste onto the CPU. The the amount of paste on there was pretty disgusting to look at. The paste was literally overflowing into the green part of the chip.. Not good. So I cleaned it up with some rubbing alcohol and put a moderate amount on and now I'm getting 63C reported in Speccy with Prime 95 running and HW monitor reporting Core 1 to be 60C and the other core to be 70. I used Arctic Silver 5.
That's more than fine. 78C might seem high, but for laptops it's not really a big issue. No harm in cooling it better,though.
Well, seeing as how I cooled it down to 63C. There was definitely room for improvement. I don't understand why they put so much thermal paste on it. The spot where you put it is smaller then a normal desktop size and they put what looks like what you would put down for a desktop in terms of thermal paste quantity.
