Speak to your friend about getting the most expensive thermal paste from a PC retailer. If he knows his stuff he wont skimp on it, and If he tries to don't let him. Hopefully you won't have to get a new processor/MOBO ontop of the extra thermal paste. Don't forget to read the instructions of said thermal paste on how to apply it - If its decent you won't have to apply it generously. AMDs generally run hotter than Intel. I have the same proccessor as you and ontop of some really expensive thermal paste (£8) i also attached a h100i cooler to my setup. This is a must if you are going to be doing any overclocker or running of high end games - Do you have an equivalent? If you don't then I'd highly recommend you getting one as you'll be replacing the paste again next year. Once done you'll need to run your system for 24 hours on idle to make sure the problem is gone. What RAM do you have again?
