I have 2 questions related to CPU thermals:
- How do you determine appropriate base thermal expectations for a new build (in this case 3950x see below)?
- What are (or how do you find) thermal limits beyond which you are risking shortened lifespan?
My Use Case:
- General productivity power user (Office, a dozen chrome tabs, trading software, video recording/rendering, etc.)
- Aorus Elite x570 m/bd (supposedly pretty good VRM)
- 32Gb (2x16) G.Skill Ripjaws V Series 360016-91-19-39 (XMP enabled)
- 1 Tb Sabrent Rocket PCIE 4.0 NVME m.2
- 1 Tb Intel 660p PCIE 3.0 NVME m.2
- 3 Tb Seagate Constellation SATA
- PowerColor rx590 8Gb Red Dragon (not a gamer)
- Thermal Grizzly Conductonaut compound
- NZXT X72 Kraken 360mm AIO
- Intake = 3 x 120mm be quiet Silent Wings 3 (side mount)
- Intake = 3 x 120mm be quiet Silent Wings 3 (bottom mount)
- Exhaust = 3 x 120mm NZXT through the radiator ( top mount)
- Exhaust = 1 x 80mm PCcooler F92 (top rear grill mount)
So I’ve got great airflow and I thought I should have plenty of liquid cooling on he CPU.
Findings at this point:
I use Blender Benchmark (all scenes) 2.81a for he CPU testing/benchmarking and CPUID HWMonitor for Temps and load checking.
Out of box (3.5Ghz base 4.7Ghz boost never ever close to it):
- 40C idle
- mid-70sC under load
OC to 4.2Ghz all-core (1.4v VCcore)
- 43-45C idle
- 83C max under 100% load 30min
OC to 4.3Ghz all-core (1.43v VCore)
- 45C idle
- 86C max under 100% load 30min
So, anyone have ideas how I should set my expectations on thermals and how far I can/should push it?
