... Running a stress test my 10900k thermal throttles at 100% usage , Later in the test at 100% usage its more around 50c with no issues ...
“Stress” tests vary widely and can be characterized into two categories;
stability tests which are
fluctuating workloads, and
thermal tests which are
steady workloads. Utilities that don't
overload or
underload your processor will give you a valid thermal baseline. Here’s a comparison of utilities grouped as
thermal and
stability tests according to % of TDP, averaged across six processor Generations at stock settings rounded to the nearest 5%:
Although these tests range from
70% to 130% TDP workload, Windows Task Manager interprets every test as
100% CPU Utilization, which is processor resource activity,
not actual workload.
Core temperatures respond directly to Power consumption (Watts), which is driven by workload. As you can see from the scale, Prime 95 Small FFT's with AVX imposes a brutal 130% workload, but with AVX disabled it's a steady-state 100% workload that's ideal for testing thermal performance.
Shown above from left to right: Prime95 Small FFTs (no AVX), Intel Extreme Tuning Utility CPU Test, and AIDA64 CPU Test.
Intel Extreme Tuning Utility is a fluctuating workload at about 80% TDP. AIDA64 has 4 CPU related stress test selections (CPU, FPU, Cache, Memory) which have
15 possible combinations that yield
15 different workloads and
15 different Core temperatures. The individual FPU test is about 115% TDP workload, the CPU/FPU combination is about 90%, all 4 tests combined is about 80% and the individual CPU test is only about 70%. All other AIDA64 test selections are fluctuating workloads which are suitable for
stability testing.
For
thermal testing, if you only use your rig for gaming or never run highly demanding workloads such as rendering or transcoding, then run
CPU-Z >
Bench >
Stress CPU, which is a steady workload at about 80% that's more typical of games with the heaviest CPU workloads.
But as
mdd1963 has already pointed out, not every AIO can handle a 10900K, so a 240 is not really adequate. The minimum is a 280 or 360, and preferably a custom loop.
Once again, welcome aboard!
