Could a Faulty Motherboard cause a CPU to overheat?

I have a pc build which consists of a Fx 6300, HD 7850 and 4 gigs of ram. A few months back i went to go take out the cooler and cpu. And i dropped the CPU in the case and some of the pins bent, which i bent back in place. When i was done cleaning the CPU and Fan i put the cpu back into my motherboard, applied new thermal paste and put the cooler back in. When i loaded up borderlands 2 i noticed that my CPU was reaching 80C within a few minutes and causing my cpu to over heat which was not normal due to it never going past 63 C before i took it out. I decided to buy a new CPU with a different cooler which is a Arctic Freezer 7 rev 2 and new thermal paste which is Arcitc MX-4. After a week i got all my stuff put everything in the motherboard and applied the thermal paste with a pea shape on the cpu. I fired of Battlefield 3 and noticed my cpu was getting to the same temps as my previous cpu. At this point i dont know what the problem is with my computer, and cant figure out what the problem is. That is why i think after some thought that it could be my Motherboard.

Your problem could be that you have poor contact between the CPU and HSF - push-pin HSF can be very hit-and-miss for that.

Personally, I would use a screwed-in HSF like the Hyper 212+/EVO/X. They might be a little more troublesome to install but you never have to worry about them coming loose.

Well i've reseated the heat sink multiple times and still have gotten the same temps. Same when i had my original stock cooler before i bought the Arctic Freezer 7 rev 2

If the CPU or something else fell on the motherboard, there is a slight possibility that it may have damaged one of the VID lines or something else of the sort that could have bumped core voltage or that one of the VID pins on your original CPU got damaged and that it damaged the motherboard socket when you put it in, causing a similar effect.

If you have not tried removing and re-installing the CPU, you might want to try that and double-check that it is laying completely flat on the socket. If the CPU is inserted slightly crooked, it may damage the CPU or socket - maybe you accidentally did exactly that the first time around.

Hey man, this has happened to me, but if this somehow happens again. Go into the bios, Intel Turbo boost probably caused you this problem (disable it) when enabled you will see a bit of an increase in frames for short amounts of time. However, this, there is no cooler good enough to keep it cool so just disable it. A second way to fix your mobo is to use jumpers, (most mobos have jumpers or a reset button ) CMOS almost never works besides changing your time. Use the jumpers on the next 2 pins and boot up your pc, than shut it down and replace them how they were ( thats how you reset your pc to fix voltage temps, etc ) Hope it helps if someone else has this problem!
