Question CPU temp at 95C during Prime95 stress test ?

[PCisverygood]

I did a stress test on Prime95 for my AMD Ryzen 5 7600X (not for very long, probably about 45 secs to 1 minute), and it's temp hit 95 degrees (what a coincidence lol). This seems incredibly concerning, as some systems only hit 45 even with air coolers (I have an AIO).

The AIO I have is the Cooler Master MasterLiquid 240L Core ARGB.

CPU thermally performs fine when gaming or idle (never goes above 55-60).

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.

How old is the AIO in your build? How is the AIO mounted in your case? If stress testing it causes those temps, and your max temps when gaming is 60 Deg C, you're in good hands.

Did you use Curve Optimizer?

The specs of my build are as follows (also I built it and fully set it up two days ago):

CPU: AMD Ryzen 5 7600X
Cooler: Cooler Master MasterLiquid 240L Core ARGB (mounted at the top of my case)
Motherboard: Gigabyte B650M D3HP AX (BIOS version F20)
RAM: Kingston Fury Beast ARGB (2x16GB, 6000MT/s with EXPO)
SSD: Kingston NV3 1TB PCIe Gen 4 M.2-2280
GPU: Palit GeForce GTX 1650 (from my old system, will be temporarily used until I am able to upgrade)
PSU: Corsair RMe 750W 80+ Gold
Chassis/Case: Montech Air 100 ARGB mATX
OS: Windows 11 Home
Monitor: iiyama ProLite PL2280HS

Notes:
AIO was released in June 2023 and is mounted at the top of the case.
PSU was released in 2023.

The 7600x is made to boost too its tj max it will always boost to under heavy cpu usage 95c unless like i did slap a arctic freezer ii 420mm on it and it wouldnt go past 75c cinebench r23 all core..

in gaming scenario's it will drop as the GPU takes more load..

being as prime 95 is a CPU torture test it will boost up to 95c ..

That said the 7600x and most other x versions will and are rated to safely boost to 95c without issues ( AMD approves )

I personally dont like it max temping like that but thats me ..

but its fine by AMDs own design !!

... Prime95 ... temp hit 95 degrees ... Cooler Master MasterLiquid 240L ... when gaming or idle (never goes above 55-60).

Test utilities, benchmarks, apps and games have workloads that vary widely.

Prime95 with default settings is a brutal 130% workload, because it uses heavy AVX coding, which is extreme compared to gaming workloads that typically range only between 30 and 70%. Even the latest AAA games that are CPU heavy and use AVX, are lightly AVX coded. As such, these games don't begin to approach 100% workload.

When running Prime95, disable all AVX test selections and run Small FFT's, which will give you a valid steady-state 100% workload that's ideal for testing thermal performance.

If you don't run apps that use heavy AVX codes such as video transcoding and rendering, then there's no point in testing for AVX thermal performance or stability, so don't run Prime95 with AVX enabled. Your Core temperatures will be up to 20°C cooler.

If you DO run apps that use AVX, then when running Prime95, use "AVX Offset" in BIOS so you don't overload your CPU. That's why AVX Offset is included in BIOS. A setting of 2 or 3 may be needed to keep Core temperatures from reaching Tj Max at 95°C.

Use Hardware Info64 (HWiNFO) to monitor Package Temperature, which is the hottest Core. Run "Sensors Only" while paying particular attention to Package Power, which is more relevant than CPU Utilization.

Keep in mind that workload drives power consumption (Watts), which in turn drives Core temperatures.
