i7 4790k Maximum Temperature

by Jetrise / January 24, 2017 4:04 AM PST

Hello All,

I have recently been doing projects in my study that require me to render for long periods of time as models and videos are usually quite large.

However, I noticed in my task manager that my CPU was hitting 100% load. I then investigated my CPU temps and they were hitting around 100 degrees at max.

I'm not a great specialist when it comes to system crashes regarding maximum temps, however, my understanding that once the system hits it's maximum temps on its CPU, it will crash the system in order to prevent damage to the system.

As stated above, it will happily sit at 100 degrees until the rendering is complete. After looking at official sources, I found that the maximum temperature is around 73 degrees for the i7 4790K.

So, this leads me to two questions: As my system is not shutting down, is it not a problem? Or is my CPU Temp Reader incorrect and I'm actually just cooking my CPU to it's death?

I'm more than happy to get a water cooled system if you guys think it's cooking my PC, however, it's additional costs which I would prefer to avoid obviously. Just a side note, my PC wasn't made by me, so is it possible this crash temp could have been changed in BIOS?

Thanks in advance.

Keep in mind that temp readings are often

"Intel specs are 72C degrees at the ihs the cores can go to about 90C before throttling."
Also this:
"The CPU does not have an actual sensor for package temperature. That value is estimated based on core temperatures, VRM load and the CPU's thermal model. In other words: it cannot be trusted."

This CPU throttles to avoid damage. I can't guess how you got it to such a high temp but usually it's old heatsink compound, dust, dirt and fan issues.

So what would you

recommend I do? Just get new thermal paste I assume.

I have to wonder if there's any overclocking going on here ?
I've seen Bob talk about it before to fix high temps also....

No it's

not overclocked at all. Stock CPU Speed of 4GHz.

Have no reservations to get out the compound, canned air and do the work. The price of parts used is a few dollars (single digit) so we get that done without any debate or discussion.

After the machine's heatsink work and cleaning is done we leave the cover off and watch the fans spin up. If they show signs of sluggishness or failure these get replaced. A general assessment of the cooling system is made at this time. If it's some stuffy box the cheap fix is to leave the case cover off.

Try a different temp monitor prog.
See if the readings match.
100c seems a bit much.
