I am using an Intel i5-4670 processor and a Corsair 200R case. I was cleaning my computer yesterday and changed my thermal paste with some Cooler Master termal paste. After I was done I noticed that the CPU temperature is between 50-70 degrees Celsius when I play games, and would like to know if this is normal/good. I would also like to know your opinion on the aftermarket cooler called Cooler Master 212 evo, and if I should change my CPU Intel stock cooler with it. The last question i have is about thermal paste. Which termal paste would you recommend me to use?
