CPU temps creeping....

I was curious if anyone is aware of intel internal thermal substance goes bad over time...

I ask this because I am running an old CPU in my current rig waiting out the release of Zen 2 here in a few months, but something i have noticed since switching my old rig from air to full custom watercooled is the CPU temp is always the hottest part in the system and seems to have increased in temps just slightly since building the rig 9 months ago...

The system:

Corsair 1000D
4x RX480 rads
26x Noctua Relux pressure fans

Intel i7 4770k
2x EVGA GTX1080ti SLI

I am using Heatkillers PRO series CPU and GPU blocks in the rig....

Idling the system, the GPUs sit at 21c and rise to the high 20s during gaming.... typically between 27-29c
The CPU idles 21c, but rises to the low 40s during gaming... when i first built this rig the CPU would max out at 39c during gaming...

Recently i pulled the CPU off to check thermal paste and placed new thermal paste on the CPU with no change in the temps... I'm using thermal grizzly Kryonaut on both CPU and GPU

Is it summer where you are? A few degrees difference is nothing to worry about, the temperature in the room could be affecting it from the last time you monitored. Low 40's is nothing to worry about.

I run the main house at 78F, but I installed a 120v 6k BTU pioneer mini-split in my office keeping the room at 72F about 6 years ago, so I could close the door to the room and game/work since the home a/c just didn't cool the room properly if I closed the door. I work on the computer as a realtor a lot, so I wanted to be comfortable in the room I worked in. I also replaced the room door with an insulated door meant for the front door of a house and insulated the room with Rockwool to stop the sound traveling in and out of the room, because the interior walls were hollow.

You're good. Those temps are better then mine on a similar configured rig.

Maybe it's related to newer versions of the CPU "microcode" that were released for the "Spectre" and "Meltdown" security issues? When the microcode updates came out, people noticed that their overclock settings behaved differently and needed more Vcore for stability. Perhaps the different behavior also causes a change in temperatures?

This "microcode" thing is first loaded into the CPU by the motherboard when you power on the computer. Then later when Windows boots, it can also load a version of the microcode into the CPU. This means the CPU microcode version you are using can change by itself through a Windows update without you doing anything.

It’s possible you have a small build up of crude in the CPU block. When was the last time it was opened up and inspected?

My System
ASUS ROG Swift PG278Q Owner's club
Asus Maximus XI Formula, 8700K, Corsair Dominator Platinum ROC 3200 16GbB, Asus ROC STRIX 1080 Ti OC version.

Actually that was something i was concerned of also, being my first watercooled system and going the route of just pure distilled water with antibacterial added, so when i redid the thermal paste, i took the cpu block apart and this is how it looked after 9 months of use... i found no residue on anything i inspected...
