Is my CPU running too hot?

Title says it all. During FireStrike physics my i5 4670K reached 95 degrees celcius (cpu temp, not core temp) with only a very mild OC (from stock 3.4 to 3.8 GHz). Is there something wrong with the stock Intel cooling solution or this normal for this particular CPU and should I look for custom heatsinks?
 
Solution


Stock college are NOT designed for overclocks. If you want to do a small oc, I recommend you getting an air cooler, such as the Hyper EVO 212. For heavier overclocks you'll need a watercooling solution.

Solution
Running things like FireStrike ion your computer is much like buying a new car, and taking it out on the highway, stomping on the gas pedal and driving it for 214 hours just to see if it will fail or not. Why do people do this to their computers but not their cars? FireStrike is designed to use nearly 100% of your CPU and GPU cycles, abd will generate more heat than any game will ever generate. So while 95c is too hot for normal usage, running FireStrike is not a normal program.

Since your system appears to have survived running FireStrike, you will be just fine playing real games. It would not hurt anything to remove the CPU cooler, and properly apply a quality thermal paste, and put things back together properly as well. But nothing is going to melt since it did not happen running FireStrike. The cooler you can keep the CPU, the longer it will last.

Okay, thanks for your answer! Two follow up questions:
- What temp should I run max on FireStrike Physics with 3.8 GHz? Is it 80c indeed? What are your experiences?
- How much cooler are aftermarket solutions when gaming or running benches? Is it like 5c or more like 15c?

I haven't got any experience with the FireStrike benchmarks, so I can't help you with that.
CPUs shouldn't run hotter than 75°C to keep a good lifespan.

About the temperature diffrence, a simple air cooler should be able to make a big difference, but it all depends on how much you spend on your cooling solution. Stock coolers are just sh*t.

Okay, thanks for the advice. Hyper X seems nice, should just fit in my case. Will do that as a first upgrade soon then, since it's not too expensive. Reseating the stock cooler and applying fresh paste also did it good, in BIOS i'm idling at 43c, in Windows 31c. I'll do Firestrike Physics again soon, hope not to exceed 80c this time with my small 3.8 GHz OC.

I think my CPU really needed that new paste, FireStrike physics got me at 55c max just yet. So I guess I'm good for now until I start OC'ing beyond 4 GHz. Thanks for the help!
