Closed I5 2500k 2 cores at 50% IDLE..? Normal? Tags: CPUs Intel i5 Motherboards Last response: December 22, 2011 1:01 AM in CPUs Share RoZmX December 12, 2011 10:02:48 PM Hey. I just recently purchased an i5 2500K and tested in my brothers motherboard. It is reading two cores constantly at 50% while on idle. The other two cores are completely dead on 0. I'm coming from a i7 960 build and i have never seen this. I heard this CPU was supposed to be better.

RoZmX December 12, 2011 10:44:41 PM nvm i think its background programs.. both of our CPUs idle around 1% in safe mode.

My 2500k idles 1% on one core and bobs up to 5% sometimes. Although, 50% on two cores for background software still seems a bit high.
