i7 4790 overheating

[Mike87]

Hi all,

 

I upgraded the CPU from my PC Build from an i5 4570 to an i7 4790. I have used my boxed cooler for years and it was enough to keep my i5 to a max of about 65°C on max usage. Yesterday I switched to the i7 and noticed that i instantly have 99°C when booting up Win10, even though it is at around 5% usage! I must add that I installed the CPU without thermal paste because I had to order it, I will add it today. I just wanted to test if the cpu is working. 

I know that the thermal paste makes a difference, but not 30-40°C?!  I checked if the Cooler is installed correctly, touching the cpu. Everything is fine. I also reset the Bios settings, even deactivated the OC function of my MB.

The only way I could lower the Temp is to set the cpu max. usage in the Win10 Powerplan to 70%.

 

The CPU seams to be configured correctly, running between 1,2ghz - 3,6ghz. 

 

I know that the box cooler is not the best but I don't understand that high temp already at boot? Do I need to reinstall some drivers or change any settings?? I checked for the newest drivers but Win10 said I am already using the newest drivers

 

Can someone please help me out?

Thank you!

thermal paste makes a huge difference..

SHUT IT DOWN. NOW

 

you should never use a cpu without thermal compound, because it makes less to no contact with the cooler

don't keep your PC running like this, just keep it off until you get your thermal paste

I will see today when I get home but I still cant believe it. I mean its a difference from about 30°C  and this while in idle...

wow ok... didnt think this makes thiiiis great of a difference... I only used it for a few minutes and then let it be. With the usage set to 70% its now at about 50-60°C.

it's actually a difference higher than 30C because you're at idle, and yeah believe it

the CPU is downclocking itself massively trying to save itself, that's why the temp went down

Ok thank you for the help.

Do I need to make any other changes in the system? Drivers, settings, etc.?

you need to reset the BIOS for good measure, but you've already done that, but really there's nothing else to do, CPU's don't require any drivers.

well, anything above 82 degrees can damage the cpu on the long term...

maybe a chipset driver update, but that's about it...

he was using an i5 before that, so i'm assuming drivers are installed, and either way i have never really bothered to install drivers on Windows 10, everything is automatic

[Mike87]

Thank you all for your help! I will check the temp after applying the thermal paste. Hopefully my box cooler is enough for the i7

yeah I reinstalled the chipset drivers just to be sure

yep, and if not, aftermarket coolers aren't that expensive...

good luck!

I know, but it doesn't hurt updating them once in a while

Imagine you have a very hot pan that you just took off the stove. If you were to put water on it, it would cool very fast. That's basically what thermal paste does. It allows for the fast transfer of heat. Now imagine if instead of using water, you took another pan and tried to cool the first pan by merely making contact with the 2 pans. That's essentially what you did. There was WAY more heat being generated than could be transferred to the cooler. Your cooler will be fine. I would be more concerned about whether or not I damaged the cpu if I were you. Just because it still operates doesn't mean it hasn't been degraded. Operating at extreme temperatures can and will degrade the cpu.

Ok I understand now. Yeah I also hope it is not damaged... Like I wrote, I only had it running for maybe a minute. Will the Intel diagnostic tool tell me if there is any damage?

[Mike87]

Just to let you know: I've applied the thermal paste and it did its magic!  In Idle the temp is around 45 °C and while stressed it's between 70-78 °C which I've read is fine for that CPU. Amazing how much the paste controls the temp.... 

I've also ran the Intel diagnostic tool, it didn't show me any errors, so hopefully the CPU didn't take any damage .

 

Thanks alot guys!
