CPU核心温度高且不断循环,@ 100%CPU负载华硕Z170 Deluxe,i7-6700K

d586

更新:将BIOS升级到1801-CPU的温度上升到70-75degC!

在BIOS中禁用Turbo模式会停止循环(BIOS 1702)CPU温度〜65-69degC。

已经更换了CPU(带有升级的双风扇散热器)和不同的散热器组合。通过Windows中的Intel测试-但仍然在高温下运行,并且在Ubuntu中运行Stress或Stress-ng。

还有人在Ubuntu 16.04上看到吗?

除非我有第二个性能不佳的CPU ...或者CPU压力过大或压力过大(我的旧i7-3820上没有)?

在安装新的2风扇CPU散热器之后,仍然要解决问题,确保BIOS中的所有组件都可以自动运行,而不是超频。它通过了Intel Diagnostics(输出低于最大以下29-45度!)-但在100%CPU负载下仍然在62-〜94deg(最高98)之间循环...

使用“ stress -c 8”进行测试时,我的新版Ubuntu PC似乎具有高温循环(和风扇速度循环)-加载8个线程/核心。压力确实可以加载到100%,但温度和风扇随后会开始循环运转...

psensor温度图5mins @ 1s分辨率较高的时间分辨率为1s采样,间隔为1分钟。BIOS中100%设置的CPU风扇并非总是如此整洁的周期:在此处输入图片说明

有没有人注意到类似的特征?

这表明存在问题吗?-散热片复合连接不良?

还是我应该看一下我凭视觉估计大约75-80度的“平均”温度?

I have tried setting the fan thresholds in bios but still see same thing.

Thanks

Addendum1 - deleted, no problem on other i7.

Addendum2 - pictures of the extracted heatsink and CPU: CPU after heatsink removed 在此处输入图片说明

Heatsink 在此处输入图片说明

OK I think that pretty much demonstrates the heatsink wasn't making good contact with the CPU top....

Addendum3: Removed, cleaned, applied new/more heatsink compound... But still no cigar...

This time 8 processes @100% Note psensor is quite high CPU load on this new i7 6700K @40% compared to 1.2% on my old i7 (speedstep or something?) 在此处输入图片说明 psensor indicated temp 3 minutes horizontal scale 1 s resolution (the fan was cycling too): Terminated the stress process... 在此处输入图片说明

Addendum4: Opened it all up again to take a closer look at the heatsink - a steel ruler and backlight...

No sign of a dome on the CPU... (checked with a mirror too to see right down at level and at different places): 在此处输入图片说明 No dome parallel to the direction of the heatpipes or on aluminium part (light shielded to help see). 在此处输入图片说明 but across/perpendicular heatpipes a bit of a gap... 在此处输入图片说明

Addendum5 - Changed the heatsink - a Double Fan Hyper D92 Still running hot and temperature cycling... 在此处输入图片说明

Is it a problem with 'stress' - cycling the loading? and 'psensor' - has high CPU load (40%) on Ubuntu 16.04?

Addendum6: Here's my i7 3820 (a 130W CPU!) for reference with stress -c 8 - it only ever reaches 74deg after a short while. 在此处输入图片说明

Addendum8: Got a new upgraded CPU cooler - marginal improvement in temperatures... but still cycling. 在此处输入图片说明 My setup:

Addendum9 - BIOS settings 在此处输入图片说明 在此处输入图片说明 在此处输入图片说明 在此处输入图片说明 在此处输入图片说明

  • All new, no dust, ambient ~26-28deg
  • i7 6700K - no OC (no plan to either)
  • Z170 board
  • Cooler Master Hyper 103 CPU fan (running ~50-100% speed - not 0 as in the graph)
  • New Cooler Master Hyper D92 Dual fan CPU cooler
  • 2 intake and 1 exhaust case fan

SOLVED - sort-of. UPDATE upgraded BIOS - it got hotter.

I disabled Turbo Mode in the BIOS - and everything became stable and lower temperature (65-69deg) at 100% CPU load.

[I have already re-seated the CPU cooler, upgraded the CPU cooler, returned the original CPU and got a new CPU without resolution]

在此处输入图片说明

To verify here is Turbo Mode enabled again:

在此处输入图片说明

Upgraded BIOS to 1801: Seems to run even hotter now!:( 在此处输入图片说明

Turbo模式-默认启用“根据此项,您可以自动将CPU内核设置为在低于工作功率,电流和温度规格限制时以高于基本工作频率的速度运行。”-根据Asus Z170 Deluxe用户指南。

但这是i7-6700K,如果没有这种悲伤,应该可以超频!
