I am currently running a non overclocked i5-3570k,
and i just bought a Noctua NH-D15.
the room temperature is somewhere around 25 degrees
on idle the temperature is around 40 degrees
under load the temp is over 60 degrees
is this normal?? did i mount it wrong. do i have a bad chip.
Ivy-Bridge did run a little warm from what I recall. Have you tried lowering the voltage to its lowest stable voltage?
40°C idle for an intel cpu is pretty normal.
So is 60°C on load.
no i have not touched the voltage or multiplier. I was hoping to overclock but don't know how high i can get since the temps are so hot already.
Reiterating what @MisteryAngel said, my i5-4690K current temps are like this while watching a YouTube video.
Try running a CPU stress test to see that highest temperatures at full load.
The NH-D15 is a really beefy cooler but it lowest temps only have a threshold form ambient temperature. The only way you are going to see very close to ambient temperature is with water cooling.
EDIT:
I have an H55 AIO cooler btw, not as good as the NH-D15 but its decent.
TJ max of Ivybridge is basicly 105°C.
But aslong as you stay arround 90°C you will be totaly fine.
you might be able to get your idle temps slightly lower, but that highly depends on your airflow inside the case, and your ambient temps.
Cpu's will generally idle about 10c above room temps so your room temp is 25c = 35+c that the min you will find your cpu at so you arent that far off.
Don't worry, it is all good.
'Sides, it is not idle temperatures that matter. Temperatures at load is what concerns you.
I've got an i5-3570K and as above my idle is ~10 DegC above ambient so usually at around 33 DegC, mid 40s gaming and 50 DeC using Prime95 with turbo set to 4.2 GHz.
So yours is a little higher but nothing that causes particular concern. My cooler is the horizontal Noctua tower which is similar but with a bit less cooling capacity. My case is a HAF XB case which mounts everything horizontally and I've spent a fair amount of time getting the air-flow just right. Plus my 980 Ti has an AIO water cooler so all the hot air is dumped externally. Ambient temps in the case are usually pretty similar to the room.
Maybe you can play with the airflow in your case too by moving fans or changing flow directions.
