Is it overheating?
The I5-4690K tends to get warm easily. Early in my usage, every system shutdown would happen because the cooling wasn’t optimal. After swapping out the motherboard and CPU with a compatible older MSI Z97M-G43 and an I5-4690K, I cleaned the paste and applied Arctic Silver 5. Once it started up, the temperatures were already high at idle—around 51°C. I removed the cooler and found good contact, so I reapplied the paste and retried. After switching to an air cooler from Acetec, temperatures dropped into the mid-30s. I’m considering a more robust solution like the NH-U9 for better performance.
My Haswell (i7-4770) runs at 1.1v and 55°C when using the original cooler.
I haven't run a stress test since this machine is mainly used for internet activities like bills, browsing, and YouTube. I'll look into it tomorrow morning at home.
It’s likely you can lower the CPU voltage quite a bit, possibly down to around 0.800, using a negative offset. This should significantly reduce temperatures even with the standard cooler. My 4590 i5 has good undervolt support and a decent aftermarket cooler that handles idle cooling well. It might just be a fan curve problem?
The board might be applying a higher than needed load line calibration; reducing it could improve peak temperatures too. Be sure stability returns after undervolting to avoid unexpected crashes. Prime95 and Asus Realbench are excellent for testing full load and transitional stability.
