I've never had much knowledge of the insides of a computer, but about 5 years ago I bought the parts for a new PC, and assembled it myself.
Recently the battery on my motherboard died, so I had to put in a new battery, which led me to cleaning out the inside of my PC (which is something I have unfortunately not done thoroughly before in my PC's lifetime).
I had never heard of thermal paste before, so I wondered about the weird gunk on my CPU and on the heatsink, and scratched it off. The thing is, I didn't apply thermal paste myself back when I assembled the computer, but I have learned that there must have been some kind of pre-applied thermal agent on the heatsink or on the CPU, which I didn't give any special notice back then.
The fan(s) in my computer have begun to blow harder with time, but I thought it was probably due to general dust buildup inside the computer. However now, even though I've thoroughly cleaned out the dust, there is still one fan that makes a lot of noise. I take it it must be the CPU fan.
I've checked in the BIOS monitor, and I can see that my CPU goes from about 25 degrees celcius to about 45 degrees celcius in about ten minutes, even when I leave the computer idle. As far as I have learned from browsing the internet, 45 degrees is way too hot for an idle CPU.
My question now is: can this be solely because of the missing thermal paste? Or would you think there has to be something else wrong as well, for a CPU to become that hot when idle?
