[Scott Diamond]

Can keep the old, just make sure you use new thermal paste.

depends if its the same mobo , whats the new/old chip?

 

[Charles Givens]

I have a g4560 thinking up upgrading to i5 6400

 

[Tuan Nguyen]

Depends on the TDP the old heatsink is made for

 

[Kris Kieronski]

In your case, yeah. If you were to upgrade to a power hungry space heater like an i7 7700K then totally no, lol.

 

[Gary Lewis]

Depends on gpu case size and airflow it helps

 

[Charles Givens]

Awesome guys thanks for all the help

 

[Martin Neal]

think u geta new cooler with the 6400 anyway

If it runs ok and keeps the temps it's ok to use the old one...if it fits that is. Same socket!
