Should I change fan/Heatsink

[RmeNayv]

I have a Lenovo c560. Changing CPU for G3240T to i5-4570t. The new cpu includes a a new fan, do I need to change it out or should the original be fine?


Thanks

when you have a new fan change to the new one

because there is a chance that there will be some dust in the old one and if it is clean and working fine without any problem then use the old one and keep the new one for future use

Thanks, the machine is only 5 months old so I will just keep the old one in. I was just concerned they might create different temp levels and one fan would be stronger or something.
