ive had my celeron 2.0 overclocked to 3.0 gigahertz for about 4 days with no crashes and the temp is only 5 degrees higher than before.
im thinking of leaving it like this but just want to know what the long term effects might be?
personally, unless you have already, id add a fan or two to the case in some way to improve air flow through the case.
I hear overclocking shortens the lifespan of your CPU, but I think its more for if its too hot, it'll shorten the lifespan. 5oC aint gonna make a difference I dont think, although I'd see what other people say as I aint an overclocking expert
