4790k High Load Temps

[W-L]

Hey guys I was helping out a friend with their new system they got and gave them a hand at assembling their computer but after booting up into windows and getting everything installed I decide to see how hot it would run at full load and his 4790K was hitting it's thermal limit of 100C on the stock cooler. So I though no big deal we just need to re-seat the cooler with new thermal paste and no dice it was still the same high temps. I was running prime95 and checked the temps with a few different temp applications and they all said things were running in the 100C range at full load, however on idle his CPU runs fairly normal at around 35C's no problem.

 

Anyone have any idea if it's just a less efficient chip since I've seen most run around 80-90C on stock when fully loaded.

 

 

I took a few photos of some results, I've heard that prime95 can sometimes overvolt the CPU but things seem pretty normal to me:

The stock cooler is simply made to handle day-day tasks. It is not made to handle full load. He should get an aftermarket cooler if he plans to keep maxing it out or running it hard.

Yes he plans to get an aftermarket cooler for sure since he wants to try a moderate overclock but even at full load I've seen other 4790k with the stock cooler at a comfortable 85C without any thermal throttling.

I'd get the aftermarket cooler first and then overclock it, because based on the temps that you get with it [the aftermarket cooler], you will have a better idea of what is a safe overclock based on the temps. Also, not all chips are created equal. Some will run hotter than others.

Just my two cents... Prime95 is a b*tch to CPUs if you dont set the voltage in BIOS properly (so I have been told here on LTT) and can cause too much heat, as you can see...

Plus, as stated before, the stock cooler is not made for full load

Yeah I definitely would not overclock with those temps and I guess he lucked out with the thermals on his chip then unfortunately.

What other softwares do you guys recommend I've used prime95 for the longest time I can remember, not too familiar with any new ones that are out there.

Prime is good, as is Cinebench. Just be sure to set your voltage in the bios and have a proper cooler.

I got recommended the Aida64

Firstly, Prime95 can overvolt and shorten the life of a Haswell CPU, use Aida64. 

 

And secondly, if you are planning to run the CPU with any overclock or under at least 60% you're going to want an aftermarket cooler. I honestly don't know why 'k' skew CPUs have stock coolers.

Prime is indeed good but if someone decides to run all stock it becomes bad fast. All stock means that voltage is Auto.... With fixed volts it cam still be good stress tester though in my own opinion its falling behind to alternatives. Like who has time to run 24-48h stability tests...

Thanks guy's I'll make sure to try out Aida 64 to see if the results are any better on his CPU, and have him get an aftermarket cooler.

I recently got 4790k and was trying out with the stock cooler. Any kind of heavy load will easily hit 80+ and eventually 100℃. Now I have got tx3 evo, though not the best choice due to my small elite 342 casing, but still managed to bring the max temp I have seen to 80 ℃.

But one question to ask, is the 100℃ the max possible for the sensor that even it goes beyond 100℃ the reading will be capped at 100℃?

It's not the sensor that's capping it can go over 100C but it's the actual chip throttling down the clock speeds to keep it at a consistent 100C and not go over that temperature, for my buddy his chip went down to 3.69GHz from the stock 4.0Ghz
