Insane Temps on my CPU

Well, I've had my computer for about a good 9-10 months now and I've had 1 hardware change that seemed to be okay, up until yesterday July, 26th, 2013. I noticed as soon as I started up my computer it started to sound like a jet taking off. I quickly checked the thermal control and noticed how pointless it was as it doesn't show any of the real temps from your CPU or GPU. I opened up speed fan, and almost fainted. My temps on all 6 cores where running at 80C- 110C ON IDLE! I was freaking out I thought my computer was going to melt or something. I turned the fan speeds up on my system through the CC but to no avail it wasn't going down. I turned off my computer and phoned Dell's tech support, had a tech remote test my computer and he said it might be my CPU pump failing. He said he will go ahead and send a new CPU pump out. I decided to go and take a look at it myself and try and clean all the dust out of it and see if that was the issue, but unfortunately I noticed that the tech that I had replacing my CPU put the CPU pump back on to tight and stripped 1 of the 4 screws that holds the pump onto your CPU. It's stuck there, with what seems to be a broken CPU pump. I took off the radiator and cleaned it up, plugged it back in and gave it a whirl and it seems to be a little cooler now all cores averaging around 65C- 80C which is still way to high for me especially during idle! I'm not a very tech savvy guy but I can usually learn pretty quick. I think it has something to do with the thermal paste that was put on during the CPU replacement. FYI the tech was the only one who touched the CPU and the pump. I also think it might be time to change the liquid in the pump itself as it seems to make a weird squirting noise every once in awhile, like it might be almost empty or something. I think the computer I received was a refurbished computer and seems to have problems more than just 1 time. I've had other problems with it regarding the parts being completely wrong when I purchased it. Thus why I had to get a hardware change, resulting in another issue. I really don't want to have them send me a new one, as I have all my data and everything on this computer. Although maybe it's a good idea to get a replacement as I don't know how the tech is going to be able to replace the CPU pump when the screw is stripped and won't come off. Hopefully there is a way I can get this fixed without having to replace the CPU pump, as the pump is running just really hot for some reason. All feedback is appreciated.

I by no means have a "weak" computer so it can't be that it can't handle windows 7 LOL. If you need anymore info please let me know.
