Right now, i have a Intel Prescott 3.0 single-core running at 47 C idle. When i run games such as css, it jumps up to 66-70 C. I might be over reacting but thats too hot! I've already bought an after market cpu fan with silver thermal paste but temps seem the same...Should i be worried? and if so what could i do to cool my cpu down. I use speed fan btw.
