Sanity Check: I Believe My R5 3600 Die Is Incorrectly Soldered To The IHS Out Of The Factory
CPU: R5 3600
Motherboard: Asrock x570 Taichi
Case: NZXT H440
BIOS version: P3.00
Load Optimized Defaults: Yes
Ryzen Maser is installed, all stock settings applied.
Fresh install of Windows 10 Enterprise.
Drivers installed from Asrock's website for the x570 Taichi.
Cooler: Corsair H115i Extreme, with 4 Corsair SP140 fans mounted in push/pull, cooler mounted at the front of the case pulling fresh cool air in.
Pump speed set to maximum; all fans set to maximum.
Thermal Paste: Cooler Master Mastergel Maker; Application method: Pea size dot in center of cpu
Ambient Temperature: 21°C - 22°C
All Stress Tests: Prime95
Temperature Logging: HWinfo
Additional temperature logging: Ryzen Master (to ensure HWinfo isn't giving false readings; the readings are identical)
Results: 88°C maximum, 87°C average, taken 20 minutes after reaching thermal equilibrium.
Second test with the only difference being the front panel of the case being removed and the dust filter is removed:
Results: 85°C maximum, 83°C average, taken 20 minutes after reaching thermal equilibrium.
Third test with stock cooler:
Results: 94.5°C maximum, 94°C average, taken 20 minutes after reaching thermal equilibrium.
Fourth test with repasted AIO (again):
Results: 94.5°C maximum, 93°C average, taken 20 minutes after reaching thermal equilibrium.
(I got a slightly worse thermal paste spread this time, resulting in the 4°C~ delta from the original.)
This exact cooler in this exact configuration was able to keep my old delidded i7 8700k at 5.1ghz, 1.392vcore, approximately 230w power draw to cpu alone, at 77°C maximum, 75°C average.
I used the AM4 bracket included in the box, all standoffs tightened with pliers as tight as I can get them; the 4 screws holding the block/pump to the CPU are wrenched down as tight as I can get them. (No, I don't usually do this, bad idea, but I wanted to ensure mounting pressure is not an issue)
How is the R5 3600 running hotter than my old 8700k while drawing 160w less power?
(Yes I know I delidded the 8700k, but the R5 3600 is soldered, so there shouldn't be a big difference)
8700k at 5.1ghz: 230w
R5 3600 stock: 70w
Both the stock cooler and the AIO can't be defective.
And I know the AIO isn't defective, it cooled my 8700k fine; dissipating about 230 watts.
The weird thing is, the AIO isn't struggling at all (as it shouldn't be with a 70w CPU), the radiator's end tanks are room temperature to the touch, not cool (obv.), but not warm either.
In comparison, running furmark on my hybrid 1070 results in the 120mm radiator's end tank being hot to the touch, with hot air pouring off of the radiator.
All of this testing has lead me to conclude that the R5 3600 that I have is defective from the factory; the CPU die is incorrectly soldered to the IHS, resulting in the heat being trapped in the IHS, not making it to the cooler.
Can anyone here give me a sanity check to ensure I haven't missed anything?
