Question i7-14700k with Thermal Bracket acts weird ?

[SteveBeast]

Hey guys, my system:

I7-14700k
RTX 4070
32GB RAM
Win 11
Kraken x63 watercooling

Today I mounted the Thermallake 1700 bracket because I had high temperatures. It helped maybe a bit but I'm not sure.
But what I'm experiencing is weird.
While playing starfield the cpu temps are always fluctuating between 42-75 degrees. It goes up and down all the time. Is this normal or an indication for a faulty cpu?
I mounted everything exactly like it was shown in the tutorial and also the watercooler is properly mounted

Can you elaborate on this? Are you referring to the one made by ThermalRight?

Make and model of your case? Number of fans in your case and their orientation? How is the AIO mounted in your case?

Run a benchmark for your platform and see what your temps are, for both high and low.

 

[SteveBeast]

yes thermalright i meant sorry

bequit pure base 500 dx case
2 fans both exhaust. 1 back, 1 up
aio is mounted in front.
As soon as i start a benchmark (or the intel diagnostics tool) temps jump to 90 in the first second, so i always stopped it immediatly.

That sounds normal. Intel CPUs are designed to operate reliably up to 100C. No need to stop any test. The CPU will automatically slow down if it ever gets too hot. This prevents the CPU from ever reaching an unsafe temperature.

Reduce the CPU voltage if you want your CPU to run cooler.

ok thanks ill try to reduce the voltag. I already set TDP to 286 W but I think it didnt help much

I already set TDP to 286 W

Most AIO coolers will struggle to keep a CPU under the 100°C thermal throttling temperature when the power limits are set to 286W. That is still a really big number.

If you are not happy with the CPU temperature you can lower the power limits as much as you like. Less power equals less heat but doing this will limit maximum performance. The choice is yours. Some people would rather have a cooler running computer than have to worry about the CPU constantly bouncing off the 100°C thermal throttling temperature. The turbo power limits are infinitely adjustable. PL1 is the long term power limit and PL2 is the short term limit. The turbo time value controls how long a CPU runs at the PL2 power limit before switching to the PL1 power limit.

You can use ThrottleStop 9.6 to adjust the turbo power limits as high or as low as you like. You can do this while in Windows without having to reboot. Very flexible.
