Hi all,
Great forum, I've been reading it for a long time now and have just about worked up the courage (okay, desperation!) to post.
I recently decided to build a new system, probably my seventh or eighth build over a decade or so, and decided on the following specs:
■AMD Phenom II X6 1100T Black Edition
■ASRock M3A UCC
■2 * G-Skill 4GB DDR3 1600Mhz Ripjaws (CL9 (9-9-9-24) 1.5V)
■XFX ATI Radeon HD 6870 1GiB
■Fractal Design Define XL Full Tower Case
■Corsair A70 after-market cooler
The Corsair A70 was delivered after the rest, so I initially threw the system together with the stock AMD cooler.
Several issues were immediately obvious.
1) SpeedFan (and others) reported the CPU temperature to be around 40 degrees C (~25-28C ambient temp) idle, whilst the Core (As I understand, there's only 1 core temperature on the Phenom IIs) sensor read around 30 degrees.
2) Under load, core would reach 45C+, whilst CPU would hit the 60 mark. The throttling of the CPU was immediately obvious. The AMD fan was screaming!
These values are surely too high (even for the quite high ambient temperature?) and the temperatures were flipped from my expectations of a higher core temperature than CPU. I upgraded my firmware, but to no avail.
I initially assumed that the CPU/heatsink had been badly seated somehow, and resumed building the system the following day when the Corsair A70 arrived. After some entertaining times getting it all to fit (the Define XL has an angled fan at the top of the case to watch out for), I booted it up and saw no noticeable difference in CPU/Core temps.
Note: I had not lapped the cooler and applied the A70 stock thermal paste, as per the directions. The thermal paste was inadequate due to the HDT design, so I went the route of several thin strips of thermal paste along the heatpipes themselves.
The CPU still throttles. The core/CPU sensors are still flipped. The system reset during a brief (few minutes) Prime95 run. I am very much confused.
Short of assuming a dodgy CPU... I'm not really sure how to fix, or even diagnose, the problem.
Anyone have any advice/theories?
Best regards,
Stew.
