Intel i5-4690 reaching tempratures of 87-100 degrees at %100 load on Prime95 using the Intel Stock cooler. Is this bad?

I am worried that my CPU may have something wrong with it or does the Stock fan really suck as much as i am told? I know it sucks but the exact second i click start on Prime95 my CPU temp goes to exactly 100 degrees and goes up and down from 87-100 degrees. I used Speccy, Real Temp, CPU-ID, and many others but they all say the same thing temperature wise. I recently ordered the Cooler Master Seidon 120V and some Arctic 5 thermal paste and will arrive tomorrow so hopefully my CPU will at least stay at 90 degrees instead of 100 at full load i know the Cooler Master Seidon 120V isnt the best water cooler but for a non over clockable CPU it should be more than enough compared the the Intel Stock cooler hopefully. I also have a 120mm Corsair Static Pressure fan in the front, 2 Corsair High Performance 120mm fans on the side panel, 1 Corsair High performance 140mm fan on top exhaust, and a corsair High performance that will be used as pull on the radiator and a Corsair Static Pressure 120mm as push on my new radiator. So i hope this helps some. Can any one give some ideas, are these temps normal?

Your cores should ideally stay at sixties or less while under load. If you reach 100's, you are gonna fry your cores sooner or later. There must be some sort of flaw on your current system at the moment. Either your cooler is not getting power, its broken or something else is off (like bad thermal pastes and/or connection between cooler and cpu). I personally wouldn't have the balls to even keep the machine on if your cpu reaches those temps. 😀

The stock cooler is awful; both at heat dissipation and noise level produced. As a general rule of thumb you don't buy a high wattage i5 unless you're going to purchase an aftermarket cooler.

That said: those are still high temps so you probably installed the heat-sink wrong.

Well thats the thing, my CPU runs 30 degrees at idle and 55 degrees max on every possible game i play that is CPU demanding even games like BF4, Hardline, ac-unity, far cry 4, Dying Light, Skyrim with enb and over 220 high graphical mods, and many other games playing them ALL at 1080p at 50-60FPS and it never goes over 55 degrees. Even some other programs that put my CPU at %100 load it never goes over 60 degrees but ONLY prime95 does this i mean the exact second i click start on prime95 BAMMMM im at 100 degrees and as soon as i click cancel BAMMMM back to 30 degrees in a microsecond.

Well i know but the Aftermarket heatsink is %100 garenteed to efficiently cool the CPU it comes with at %100 load as long as no overclock is being used which is what intel says so if the cooler does not keep it cool it is intels fault. And i know i installed it right i have installed well over 40 of them in my lifetime and never dealt with something like this.

Ok man thanks! :) and why did prime95 even come out with a new version that lies to everyone telling them their CPU temps are 100 degrees and such? Did they do it as a prank?

the newer version isn't lying, its just putting a unrealistic load on the cpu.

" ... Core i 2nd, 3rd and 4th Generation CPU's have AVX (Advanced Vector Extension) instruction sets. Recent versions of Prime95 run AVX code on the Floating Point Unit (FPU) math coprocessor, which produces unrealistically high temperatures. The FPU test in the software utility AIDA64 shows the same results.

... Prime95 v26.6 produces temperatures on 3rd and 4th Generation processors more consistent with 2nd Generation, which also have AVX instructions, but do not suffer from thermal extremes due to having a soldered Integrated Heat Spreader and a 35% larger Die. ... "
