1800X Temp Offset Causing Noise

[Goodmane]

Hello, as you probably seen from news AMD Ryzen R7 1800X and R7 1700X has +20C degree off set in temp readings. As you can see Ryzen Master reports it as 35 C but everything else sees it as 55-60 depending on load the CPU is under. It fluctuates +- 5 degrees. That fluctuation is not the problem though. When CPU hits +55C it will report +75C in every other program, including bios. And Asus hardwired Crosshair VI to ramp up the fans to 100% when CPU hits 76C, which is actually only 56C.

 

 

I've tried changing my fan curve to 60% at maximum. But it keeps hitting 100% when it thinks it's 76C. There is no option to move the slider more right side so I can keep it at steady 60% even when faulty report says 80-90C (which is 60-70C with real report from Ryzen Master). Even in bios max temp you can fiddle with is 75C and then motherboard takes fan control over and hits 100% button. Anyone know how to get in front of this issue? Or heard AMD will patch this issue other then just their Ryzen Master software?

Get a beefy noctua cpu cooler.

It makes no sense why AMD decided to have this offset, and it is just plain stupid.

If you set the fan speed to run at 70 or 80% can you keep the CPU below 55°C to prevent it from ramping up the fan speed?

meh forgot to include specs,

Ryzen R7 1800X

Asus Crosshair VI

Thermaltake Water 3.0 Extreme S

Bios ver;1002

I have 2x NF-A14 industrialPPC-3000 PWM Noctua Fans on the cooler. It gets really loud above 60%

I don't want to use them above 60% unless I'm rendering.

Those fans running at 100% are guaranteed to drive you insane.

Can you connect the fans to a non-CPU header, and have them controlled off the motherboard VRM temperature or something instead?

That's what I was thinking, but All other spots are filled with same Fan, I have 4 more of those baddies circulating air in my case for the non-blower style graphics card  
I will wait for more to see if anyone else had same issue, if no body else replies that's the way I'm going, even though I have to call some smoking friends to figure out new air circulation in the case

I have found "T Offset" in Bios-Uefi, It says default is set to 63. I've tried playing around with it. If I increase it even by 1 it shows temp as 20C in bios, which it normally shows 60C. If I drop it below 63 it doesn't do anything. Anyone know how T Offset works?
