Idle temps

post #1 of 12
Thread Starter 
I build my first rig today and i am worried about my cpu

i7 3770k

When its idling the temp difference between the lowest core and highest core can be 19c but when i stress test the system with prime the temps are almost the same.

Does someone know why this is happening?

Tried it with 2 coolers H100i and stock no difference

Hi.
Things to try.
1. Use HWmonitor to see if the core temps have the same differences.
2. Just for good measure, you can reapply thermal paste. (Or it has a curing time)
3. Maybe the heatsink is not seated correctly.
4. Maybe it is just a stuck sensor.

turn on high performance in power options and check temps while idle on desktop/prime95

Nothing changed sadly Prime temps are still fine (high but thats caused by stock heatsink atm)

HWmonitor gives same data as RealTemp

Dont think heatsink placement is wrong it a stock cooler wich is mounted as it is supposed to and the same problems happened with a h100i wich I am gonna test tommorow again when I can get my hands on some new thermal paste.

Maybe it's a stuck sensor like said before as I'm having the same issue with my 3570k.

What are your temps at load?

Full load with prime max temp 65c all cores are in margin of 3-4c of each other (h100i)

Idle isn't as important as important as your load temps and even with your idle it isn't harmful. I get up to 40-50s on all cores at idle and up to 100C on load. Your temps are good at load.

Just throwing this out there if gour using ipgu I believe that will make that core always run hotter cause its closest to.igpu
