Help! Getting a 20 degree difference in temp reading between core temp and cpuid

[Adamac]

Basically says it in the title, I have an 8350 from AMD and core temp is reading 44 degrees idol while cpuid reads around 32 degrees idol??

Idle temperature is meaningless, particularly for an AMD CPU. Use AMD Overdrive to check your thermal margins at idle and at full load.

Well this is quite depressing considering I just put the TX3 on yesterday and got some new fans yesterday.

Somethings not right here, it got cooler under 100% load.

It's excellent as you have 54°C to the throttle temperature. However I doubt it will be good at full load because a TX3 probably can't cool that CPU at full load; it will throttle. I use a TX3 to cool an Intel i5-4590 and it gets up to 80°C on Prime 95. An AMD CPU can't run that hot.

Any reason to why overdrive shows my thermal margin gets cooler under more load??

That's much better than expected. You still have a good margin to throttle and you should be very satisfied.

Ohh, does that mean it is 30 degrees away from reaching the safe limit?

It obviously gets hotter if the margin is lower. At close to 0°C margin it will throttle. Let the stress test run for a while and keep on monitoring the thermal margins.

Alright will do, thanks for the help.

Run Prime95 Small FFTs and monitor the frequency and thermal margin of all cores. If the frequency drops, then it's throttling.

I've been using HeavyLoad for about 6 minutes now and it stayingg at around 19-21 degrees and the frequency is staying at a solid 4018.

I just tried it and it doesn't stress the CPU. Run Prime95 and let me know.

 

[GhislainG]

The TX3 fan on my i5-4590 barely increases in speed when I run the HeavyLoad CPU stress test and the CPU temperature is 60°C in a room at 22°C. When running Prime95 Small FFTs, the fan runs at full speed (it's loud) and the CPU temperature increases to 86°C in less than one minute. The TX3 is less noisy than the stock Intel cooler, but it isn't much better.

No reason to torture your CPU with Prime -- You can use OCCT, or even the AMD stability test, to crank your rig to 100% load.

Your temps/voltage look good. The TX is doing its job, and you have some nice headroom to take your chip higher

The headroom exists because he hasn't yet stress tested the CPU. OCCT should significantly lower the thermal margin.

Sooooo I had realized that my cooler was facing the wrong way, lol. Flipped it around but it really didn't make a huge difference. I did run prime 95 for about 30 minutes or so and it didn't drop below 18 degrees thermal margin.

 

[GhislainG]

Then it's fine, but the fan is noisy at full load.

I set it run silent in my bios and the temps seem to be fine so far.

 

[GhislainG]

At full load, the fan will run at maximum speed, no matter what the settings are. Silent allows the CPU to run a bit warmer before increasing fan speed.

Depending upon the element of 'Prime' that you ran, being that the stress is well beyond any reasonable 100% load you will ever run in every day use, you may safely add a likely 5C+ of additional thermal headroom.

Since you are getting good at removing your HSF the next time you do so, check the second series of numbers on the chip. See where it says, "-- 1429 --" on the second row ? ...

That means that the chip was fab'd during the 29th week of 2014.

Piledrivers baked in the Summer of '14 are not new steppings, but do feature minor core revisions (C0-j to C0-k) which tend toward serious improvement in the FX- "Power Delta." It would not be a surprise for you to run 4.5GHz at less than 1.4v, or 4GHz at 1.25v or less.

So are you saying this chip can take some OCing with this cooler?

That's what he says, but make sure it doesn't throttle when gaming for hours.
