    Posted: 27 Apr 2016 at 8:07pm

I have recently updated my Asrock Z170 Extreme7+ BIOS from P2.00 to P3.00 and since then the CPU temps have been sporadic and higher than usual and especially under minimal load it just seems to run hot. (http://i.imgur.com/qxrhT8P.png) 

CPU/Processor: Intel 6700K
Cooler: Corsair H110 GTX

prior to the upgrade everything was around 30c to 40c idle. During the upgrade cycle the FANs were screaming and post upgrade temps were sitting around 85 to 90c for around 20 mins. I tried the usual solutions, turn off let it cool down, downgrade bios but nothing appears to have helped.

I suppose this is more so a warning for others for upgrading.

Motherboard: Asrock Z170 Extreme7+

Anyone had this or know someone from Asrock that can help?

What do the temps look like in BIOS?

BIOS it's around 55-60c.

I'm using the 3.00 UEFI version on my Z170 Extreme7+ board, and I have no such issues with sporadic temperatures in the UEFI whatsoever.

I have learned that my one experience with something like this does not mean it applies to everyone. In your situation, it is related to your CPU cooler.

But, I must say that the behavior of the CPU_FAN2 header has changed with the 3.00 UEFI. Personally, I think it is not what it should be. It will cause a three pin fan to run at full speed, which seems what you are experiencing.

Your CPU temperature problem may be related how you have the pump power cable connected to the board. I talked about that in the other thread about this topic, which I have not yet checked today. So I have no idea what your configuration is.

Please let us know how you have your pump power and CPU cooler fans connected. Do you use the Corsair Link software?

Hi parsec. thanks for the response.

I've double checked the configuration of the heat sink and everything is attached correctly, this is a H110i GTX which connects directly to the mains (SATA) for power. So it's not CPU pin related that just presents RPM data to the motherboard. Everything is connected correctly and yes I use the Corsair Link software.


ASROCK support told me to get another cooler! which I don't believe is the correct answer. The CPU temps should not reach 80 when running a Windows Defender scan sitting around 30% cpu usage. Confused

I've order new CPU thermal paste but I don't believe that's going to be of assistance.

Application of new thermal paste has not resolved the issue.

I'm also in bios P3.00 and all temps are OK. The water cooler is a Corsair H105. 

When I run Windows Defender, CPU and board temperatures s are much less than in your board.

Also, powers shown in HWMonitor are much inferior than yours, and I suppose that in your config the CPU VCORE is on the high side, since your VID is 1.445 V (against 0.820 ~ 1.275 V in my board).

 BTW, the MAX. Package Power shown in your HWMonitor (88.51 W) is almost the i7 6700K TDP of 91W, what is not good for everyday run :

 

Defender scan (with 21 ยบ C Tamb):

 

 So, I wonder if your problem is not related to power configs in bios, as for instance:

- In OC Tweaker Screen > CPU Config, is Intel SpeedStep Tech enabled?

- In Voltage Config > CPU Vcore voltage, instead of Auto, I prefer Offset Mode with Offset Voltage set to Auto and CPU Load-Line Calibration set to Level 5.

- And in Advanced Scren, CPU Configuration, is CPU C States Support enabled?

 

Of coarse, these configs are very conservative and for everyday run; for benching I set them in a very different way  ....Big smile  

regards

Hey squawker.

I've done all of the steps you have suggested, everything was either enabled or Auto prior - however still getting a similar result. 


I'm sort of stuck with the next options - I've also logged a support case with Intel as well.

Try uninstalling the Corsair Link software and check without it. Also check to make sure your pump is actually working. I know it is unlikely but it is possible that it failed around the time of the BIOS update, as you have already flashed back to a previous version and it did not correct the issue we need to properly rule out the cooler itself. Ideally I would have liked to see you try an air cooler on the system to test with. 

Good call putting in the support request to intel, we have seen a few defective Skylake CPUs here on the forums (more failures than I have seen from intel in a long while now) so it is a possibility.

Another cooler is not a fix for your situation, unless it suddenly became defective. That is the only reason I can think of why support told you that. If you could try another CPU cooler, that is something I would support if we can't determine what is happening.

I agree you should not be reaching those temperatures with a Defender scan. That is, if the pump is running at full speed, and the fans are at least at ~800RPM.

I'm not familiar with your model of CPU cooler, regarding how the fans and pump speeds are monitored. I looked it up but the details of connecting the fans and pump speed monitoring were not clear.

I understand the pump's power is supplied by a SATA power connector, but how do you monitor pump speed? Some of the other Corsair AIO liquid coolers had a three pin fan header with a single RPM wire for connection to a three pin fan header on the board. Not for power but simply for pump speed monitoring.

Do you know what the pump speed was before the 3.00 UEFI, and after?

In your UEFI picture of fan speeds in the UEFI, which one is the pump, and which are the fans? Knowing that information would be a big help. You are using the stock Corsair fans, right?

I doubt the fan speeds would cause such a high temperature (70C!!) in the UEFI, even if they were running very slow.

It also does not make sense why the pump would suddenly be running at a lower speed, but that is my guess about what is happening. I think the pump speed is either much lower or is not running at all. As Xaltar said, why the pump would suddenly die is quite a coincidence.

If you are still using Corsair Link, can you see a pump speed reading? If you can adjust the pump speed using Corsair Link, set it to full on as it should be.

We really need to know what the pump speed is, how the pump speed is being monitored, and also how the CPU cooler's fans are connected to the board.
