VERY hot ferrite core chokes?

post #1 of 3
Thread Starter 
So I have my motherboard here and the phase list says that I can overclock a 125w TDP CPU if I have cooling.
I have sinks on the vrms if that's enough.
The vrms are not what I'm concerned about, but my ferrite core chokes get pretty hot while running prime.
Like 1,2,3, ouchy hot.
My vcore is like 1.375
Is it fine?

Hyper 212+ cooler so no airflow to the vrms.

Chokes usually get hot. I can imagine the no airflow to VRM situation makes it worse, though the MOSFET sinks should make it better. Hot chokes don't necessarily increase the danger though, they can take much more temp load because unlike MOSFETs they aren't fragile, active transistors. They're just metal coils in boxes that are supposed to get hot.
Is your 945 the 95W or 125W model? How bout the temps of the MOSFET (sinks) themselves?

Thanks!
125w model.
The temps of the MOSFETs (by touch) are mildly warm.
Have any idea how to check through software?
My TMPIN2 is not connected to anything so it always shows 23.
TMPIN1 gets 55C running prime.
TMPIN0 is always at 38.
