Thermal Paste

[kjframe]

So I took my tower outside to air dust it cause it was getting pretty rough looking... 
I never had an issue with over heating or anything until I did the air dusting. 
There was a lot of dust and build up around the CPU
I have never touched the thermal paste since i put it on 3 years ago.
I feel like that is poor maintinance on my part. 
But could i have possibly like blown some of the old thermal paste out from between my CPU and the heatsink?
Because since then I have had some fairly big over heating issues of like 75-90 degrees C

Fans spinning? Reseat CPU Cooler and put on new thermal paste?

Any chance you damaged the fan when dusting it off, is the fan rpm still ok?

It's very unlikely to remove any thermal compound or material when dusting but it's not a bad idea to replace older thermal compound if heat issues arise, just be sure your fans are proper working and installed back where they were previously.

Earthbounds right, reapply thermal paste and consider getting a new cooler
