Intel i7 8700 Temperature Issues

Recommended Posts

Posted · Original PosterOP

So I have owned my PC for around 6 months or so now, but have just been so worried about my CPU temperatures and performance the whole time. I previously created a thread about this but I kinda just got mixed responses and I have since tried the suggestions but still have concerns.

 

PC Specs:

Case: NZXT  H700

Motherboard: ASUS ROG Strix Z370-F Gaming

CPU: Intel Core i7 8700

CPU Cooler: Cryorig H7

 

So one of my problems is the temperatures just seem too high. These are the average temperatures I get:

Cold Boot BIOS Temperature: 35 degrees celcius

Idle Temperature: 40-45 degrees celcius

Gaming Temperature: 65-80 degrees celcius

Full Load / Stress Test Temperature: 80-90 degrees celcius

 

I have attached a photo of the location of my PC, which is under my desk and fairly enclosed. I am not sure how much this would affect the airflow of my PC, and overall the temperature.

 

When I first got my PC I manually set my CPU Core voltage to 1.2V as it was automatically setting it to almost 1.4V which is ridiculously high.

 

I am unsure if this is related to temperature, or my BIOS power settings for the CPU, but I noticed during stress tests I get power throttling.

 

Also, I noticed when gaming and stress testing, my CPU turbo speed dips below the usual 4.28 GHz max speed that I usually get. I don't understand why it can't maintain a stable max turbo speed.

 

So overall, the temperature issue, power throttling and turbo speed reduction are the issues that are concerning me. Could someone please give me some advice on what I should do? Thanks in advance.

Have you checked to make sure your setting of 1.2 has stuck?


I WILL find your ITX build thread, and I WILL recommend the SIlverstone Sugo SG13B

 

Primary PC:

i7 8086k (won) - EVGA Z370 Classified K - G.Kill Trident Z RGB - Force MP500 - Jedi Order Titan Xp - The venerated Hyper 212 Evo (with RGB Riing flair) - EVGA G2 650W - Black and green theme, Razer branwashed me.

Draws 400 watts under max load, for reference.

 

Linux Proliant ML150 G6:

Xeon X5560 - 24GB ECC DDR3 - Asus DirectCU GTX 760 - old Seagate 1.5TB HDD - Dark moded Ubuntu (and Win7, cuz why not)

How close is the back of the PC to the rear of the enclosure? Could be recycling warmer air.

 

Is the move to this location new? Is the inside very dusty? (The top looks pretty dusty which is why I ask.)

because current limit is set too low. Go into the BIOS and raise all power/current limits as high as possible (or just 999).

the temperature issue,

1. Case airflow. How did you put the case fans? I hope there's more than 2 fans.

 

2. Voltage. 4.3GHz i7 8700 can use less than 1.2V, more like 1.1V. I'd rather use adaptive mode instead of manual though, you can reduce voltage in adaptive mode with a negative offset number.

 

3. Mounting pressure of the CPU cooler. The more force you use = the flatter the paste between the cooler and the CPU gets = more heat gets through. Of course you shouldn't use as much force as drilling a hole on the wall with a hand drill, about as tight as building a small furniture with screws and bolts (Ikea, yes you) like a little bookshelf will do.

Try reapplying thermal paste or replace the cooler, with something better like Cooler Master Hyper 212 EVO!

 

All know Intel's stock coolers are shit for Extreme Gaming and CPU intensive tasks!

 

But, first, before buying cooler make sure you replace your thermal paste!

Yes, I double checked and it still seems to be applied correctly.

It is around 6 inches or so from the back of the desk, so it probably would be possible it is recycling some warm air. This location has been the same since I got my PC, so around 6 months. I checked last night and it turned out it was quite dusty, especially on the intake fan filters so I gave them all a clean and it seems the temperature has dropped slightly by a few degrees, but nothing major.

If I raise the power limits, will this increase my temperature by much? I am a bit worried about doing this. Why is it so low in the first place anyways, I thought it would be set to a limit that can at least sustain it's max turbo speed.

 

1. It has the default fan setup of the NZXT H700. 3 intake fans at the front, with 1 exhaust at the back.

2. Really? I chose 1.2V because I found someone said to set it to that. But if it can be set to 1.1V, I would definitely be willing to try that. I don't know much about adapative mode and how I should set that up, I heard that it can tend to use a higher voltage than what is set though, so I am a bit worried about that.

3. I considered this when I reinstalled the cooler after I first got the PC and the PC Shop had installed it. I was worried it was not installed correctly as I was getting the same temperatures, so I did it myself and got the same sort of temperatures.

I have already tried reinstalling the cooler, but I got no better temperatures than what they were with the PC Shop's install of it.

What voltage to you run on your CPU? And did you adjust any of your power limits?

No it won't, just a little.

 

With offset mode (adaptive only changes voltage past 3.2GHz, not exactly the way for an undervolt), just start with no offset (or a tiny negative number), run stress test (I only test for 1 minute at this point). If it's stable, drop the offset by 0.02V or 20mV and redo the stress test again. Keep on doing this until it does freeze/crash, then take the number 40mV higher than the one you crashed on as the target for long term stress test (an hour should do).

 

Does the thermal paste cover up everything? I mean, even Hyper 212 do better which is weaker than the H7

Why? He already has an H7 which is better than a 212.

What about power limits for the CPU? Because I'm getting power throttled with turbo speeds at whatever my motherboard has set the power limits to.
