CPU run hot on ROG Board

[Inf1n1ty__]

Greetings, I have a Problem with my CPU (i7-4790K) on my ROG Maximus VII Hero.

My CPU Temperature is getting hotter and hotter.

For normal I have Idle Temp around 30 Degree.

Now i have 45-55 Degree (Celsius) with my Corsair Water Cooler (H100i GTX) und 65-75 Degree with Stock Cooler,

I have got an new CPU from Intel so this is not the Problem.

Anybody else has this Problem? Is my Board defective?

Thanks

Sorry for bad English 😉

Hi,ive had the same board and cpu but with a corsair h110gt, i see your max temp of 98c....i suggest removing the copper plate on your cpu block and checking for scale, my 110gt was clogged after only 6 months and gave 98c on cpu temps.

Hello and thank you for your help.

I think I don't understand you right so I have to ask you: You mean the copper plate where the CPU is mounted? Or the Copper Plate on side of the Corsair Cooler?

I have bought a new Mainboard and my temps are not getting better..

I ran Intel XTU Stress Test and my PC turn off after 5 min.

Then I looked at bios and I got temps at 76° Celsius! (IDLE in BIOS!!)

Then I restarted my PC and my link got a Water Temp of 43° (so far I could have seen this after reboot).

When I turn off my PC and wait for 15 Mins it is at 42° on Idle again..

Thank you for your help

If you have more than one program capable of monitoring temps, then there is a chance that you're getting bad readings... this is happening when multiple applications are polling the same sensors in the same time... However, the BIOS reading should be accurate as other applications are not loaded yet...

54C (I assume that it is celsius) is still high for idle/BIOS... is your cooler's fan spinning at max?
When you mount your Corsair H100i, make sure that the pump and fans are spinning!

Hi again,

so i have mounted my Corsair and the Idle Temp at first start went down to 27 ° Celsius and now my Idle temp is around 33° again.

I am very happy to see this. In Prime 95 in FFT Mode I still get over 90 ° Celsius but I think the reason is the "Auto Mode" I have turned on in Bios.

I think it was a mounting problem but I am not sure about this.

I have uploaded the Screenshots of the HWinfo64 Application.

Can pls somebody check if the temp/Voltage on this screenshots are ok?

At last I wanna answer you questions:

1. I use Gelid GC Extreme Thermal Paste
2. I just use one Program to check my thermal Condition.
3. I have turn on "Balanced Mode" on Windows now.
4. Pump is working normal on Corsair and Noctua Fans are always spinning on H100i.


I want to thank all the good People in this forum for the great answers!

Prime95 runs your cpu hot, try using ROG Realbench, temps should be better with that. You could try lowering the voltage some more too.

i7-4790K was released Q2/2014 and is EOL. Your system is now 2-3 years old.

Power supply could be de-rated from age, now maybe only 60%~80% the power delivery (and regulation) it had when new. Try a new PSU, if you can.

Motherboard VRMs (and electrolytics) could also be de-rated from age. More "dirty" power passed to the CPU socket, where the solid-state regulator diodes/caps inside the CPU have to do the work of cleaning it up and thus add heat to the CPU package. Motherboard replacement is the only fix, sadly.

Good old "CMOS" battery (CR2032) on motherboard is probably starting to fizzle. Can cause all sorts of apparently unrelated and random issues when failing. 3-packs available at your local Dollar Store, so while it may not fix much it's still definitely worth trying.

Hello again,

So i have tried some things:

1. I have overclocked back to 4.5 GHZ and i have idle temp at 50° Celsius! with Corsair Water Cooler again! Then I have resetted my Bios with F5 Key
and it changed nothing!

2. I have cleared CMOS at Bios and voila I have Idle Temp at 33 ° again! (so I have waited about 5 Mins to start the test, maybe it cooled a bit down).

So I think that my Problem could be a Bug in Bios (i don't think I had this error with older Bios).

In Realbench after Reset i get 72 ° Max. This is okay I think (For your info: Luxmark crashed).

I do not think the age of my board is the Problem, I bought it in March 2015.

In my 2nd PC i got an Asus Crosshair V Formula from 2012 with an FX-8350 and this still works fine.

Thanks all.

Good to see a clear cmos got things back to normal, F5 should have got it back to normal too I'm not sure why it didn't.

Try reinstalling Realbench to see if that fixes the Luxmark crash, if it doesn't reinstalling windows will.

33c idle temp is great and 72c Realbench temp is great too, that looks much better. 🙂

I think it was a bug in Bios with OC Mode.

I have overclocked to 4.5 Ghz and my vCore went up to 1.250V (seen with CPUID).

Now i have cleared CMOS and set Core Voltage manual to 1.165V and Cache Voltage to 1.4V my System run fine at 69-72 ° with Intel Stress Test.

I have also switched back to Corsair Stock Fans, but this was not the problem, with stock fan's i was at 82-86° at Stress Test.

I hope i found the right settings now.

Thanks all!

You shouldn't need the cache voltage at 1.40v or did you mean 1.14v ?
