I know it depends upon your fan setup/radiator setup/etc, but I am wondering what you guys generally have set (in terms of fan percentage) at the major temp points (30,40,50,60,etc). Any help or input here?

I have a Kraken x61 AIO (with Fractal Venturi HP-14 PWM fans) and (4) be quiet! Silent Wings 2 PWM fans for my case.

It's not good to base your case fan speed on your CPU core temp. That will result in your case fans being throttled up when your case temp is low and your case fans being throttled down when your case temp is high - with a high end GPU, you can expect like 70% of your heat generation to come from non-CPU sources.


Klutz0! I missed your posts for like a day, sorry. That throttle shouldn't be happening, i'm not sure why. The FPS you should get at 4.6ghz is about 4.6fps but i've got 4.67 when running on realtime/high priority. I have no problems with temp throttling at any temp i have hit.

The nearly instant temperature rise is completely normal. CPU's change temperature VERY quickly! Running the power intensive tests at high overclock, you can go from 25c to 75c within 1 second, yet not peak more than 80-85c or so ever (if you have good heatsink/rad fans and your case temperatures do not rise).

Some people think that temps tend to rise over longer periods, like 15 minutes or 2 hours - that's only the result of poor overall cooling, like a laptop that's not built for a constant load or a case with badly insufficient airflow. When i did long term testing (logging with an hour load) my peak temperature was actually reached by 3-5 minutes or so, dropping off after that because my room temperature fell by ~3c over the test duration.

What motherboard do you have? It looks like a mobo issue but i can't see any of your posts talking about which one it is. Maybe it's even a VRM throttle if it can't take 1.4v

for the record, my 4.5ghz cinebench is 1013 at the moment

My motherboard is a Gigabyte Z170n-wifi. For most of my previous posts I've reverted to 100% stock settings - no overclock at all.

Thanks for the info about temps!

I'd RMA the CPU.

Assertion of the PROCHOT# signal is independent of any register settings within the processor. It is asserted any time the processor die temperature reaches the trip point


The temperature at which the PROCHOT# signal goes active is individually calibrated during manufacturing. Once configured, the processor temperature at which the PROCHOT# signal is asserted is not re-configurable.

NOTE: yes that's old but I'd assume it's still the same, someone can correct if wrong.

What do you set your case fans on? Im having difficulty setting mine to how my last board was.

Currently I have my h110 plugged to the two CPU headers, controlled AUTO (pwm) mode, Max 70c - 100% Middle 50c - 40% Min 30c - 30% with a 2.8sec up down delay.

Case fans I have going off CPU temp with Min 30c - 60% Middle 50c - 60% and Max 70c - 70%. DC mode no delay.

My temps are fine, problem I get is when I open programs they ramp up a bit due to me going from idle to very light load and its annoying!

My p8z68 was so much easier, Case fans stayed at 80%, CPU fans ramped up when I dinged 70.

At 54...

And I just noticed 2 new flags that went to "yes". I do not recall seeing these before :
  • IA: Max Turbo Limit
  • IA: Turbo Attenuation (MCT)


Annnnd... it starts dropping to 800MHz pretty much as soon as Core #0's temp hits 55... frown.gif


Edit 2

I'm going to rollback my BIOS to version F4 (currently on F5). These are the only 2 BIOS versions available.
You have the Z170N WiFi board, right? Not my first, second or even 10th choice for overclocking, but it is what it is.
I think you need to do some serious troubleshooting and if you come up with nothing consider another board....I'm a longtime Gigabyte fan but that's sort of a low end board, IMO.

EDIT: I should have read further before posting.
