I got a used CPU with dry thermal paste, I cannot afford or buy?
Man , well u can get cheap thermal paste atleast from ur own pocket money if u want , it won't be nicest compared to those fancy cm or thermal grizzly ones. But would be better than nothing. And u can use that dried paste , just would say it might not work like new , but will get the work done. If you encounter any often pc crashes or very high cpu heats probably 7585 degrees and above even under no loads constantly , u better should buy one paste. Else the cpu could get damaged on long run. U can monitor cpu temps through hwinfo application. And i wont, recommend any kind of cpu overclocking or boosting. Better let it stay at stock speeds
