When I launch an application, my temperature seems to always spike up to 50 C. I idle between 36-40C if I'm not doing anything, but it just likes to spike whenever I launch something. It also spikes to 45 C when I go to my browser switches pages. My steam downloads also push it up to 50C. Although I have never seen the temperature go up over 70 while gaming, I don't think this is normal? (I have tried both overclocked and stock settings on it and both yield the same results.)

The idle temperature for i7-4790k is 34° to 39°C, normal temp 55 to 65°C and max 67°C. This temperatures are when running the CPU with stock coolersWhat kind of cooler you have?
I'm using a Corsair H100i.
My ambient temperature is ~30C (I don't keep the air conditioning on all the time.) I'm not really concerned with my load and idle temperatures, they're not incredibly high, I'm concerned with the temperature spikes. I'm not sure if it should be doing that. -

I've reapplied the thermal paste and the Corsair Link detects both the pump and radiator fan rpms and lets me change them. Do you think this H100i might be defective? (I used IC Diamond 7 carat paste.)I don't think that your h100i is broken, check the radiator fans and see what speed (rpm) they run, look for any dust. I would re-apply the thermal paste and see what's going on. If there is no change it means that's the normal temp for i7-4790k. I wouldn't worry to much if your temps are below 70 C under load
When applying new thermal paste, I would first make sure that the back plate screws and mounting ring are secure

blujadajhdja,
Processor temperature respond instantly to changes in load, even small changes. What you are seeing is completely normal.
K6-II,
Part of my work here at Tom's is to be as informed as possible concerning Intel processor temperatures. As the author of the Intel Temperature Guide - http://www.tomshardware.com/forum/id-1808604/intel-temp... - I have an ongoing commitment to research the topic so as to provide our readers with the most accurate and up to date information available.
So respectfully, my question to you is how did you come by this information?
Either you are misinformed, or all my 2,500 hours of research and testing over the past 8 years has resulted in me being misinformed. As I don't want our readers to be misinformed, I'd like to get this cleared up.
Please respond with the source of your information.

I apologize, but I've search and found this article on http://www.buildcomputers.net/cpu-temperature.html, and I just took the temperatures for an i7 Haswell according to their studies

While you're in this thread, could you please tell me if temperature spikes like that are normal?

My pump and fan RPM is around 1000 on my "quiet" profile. While gaming, they go to around 2000 RPM.

blujadajhdja,
That's the first thing I said in my previous post; "Processor temperatures respond instantly to changes in load, even small changes. What you are seeing is completely normal."
K6-II,
Thank you for the link. I can tell you with 100% confidence that the information shown on buildcomputers.net is wrong. It doesn't even agree with Intel's specifications, probably because no one really bothered to look it up.

No worries. I can appreciate that. My concern is the spread of misinformation. Once it proliferates, it's very difficult to correct, and there doesn't seem to be any shortage of misinforation.
The topic of processor temperatures is very complicated and confusing, at least in part because Intel's engineers and lawyers have written thermal specifications that are about as clear as mud ... unless, of course, you're a thermodynamics engineer.
Perhaps you guys should give my guide a read, so at least you have something solid to use as a reference. It's a Sticky right here at Tom's posted in the CPU's Forum and the Overclocking Forum. Just click on this link: Intel Temperature Guide - http://www.tomshardware.com/forum/id-1808604/intel-temp...
Please let me know if you have any questions.

blujadajhdja,
I don't think I answered you question as thoroughly as I could.
For your benefit as well as our readers, there's nothing wrong with your temperatures with respect to the information you gave. However, when posting information, ambient temperature is always a critical variable, as is what monitoring software utility you're using and what utility you're using to test your load temperatures.
As detailed in my guide, (I do hope that you please give it a read), Standard Ambient is 22C, which is the temperature at which Intel's tests and certifies their processors, and is also the industry standard to maintain a proper computer environment.
At 22C ambient, your 4790K should idle in the high 20's, with everything at stock including BIOS settings, because the processor idles at less than 0.0800 volts and less than 2.0 watts.
Also at 22C ambient, your load temperatures should not exceed 80C, so mid 70's are fine.
The actual spec for your CPU temperature is 72C, so the corresponding Core temperature is 77C, because there's a 5C gradient between them. Of the two, Core temperature is the critical measurement. I recommend using Real Temp or Core Temp. There are links to both in section 10 of the temp guide.
CPU temperature and Core temperature are not interchangeable terms; they're completely separate measurements from different types of sensors. Even Intel contradicts their own terms in the software utility "Intel Extreme Tuning Utility", so it's no wonder why everyone is so confused.
Again, please read the guide so you can understand what you're seeing on your 4790K temperatures.
Hope this helps,
CT

Thanks for your time, my ambient temperature was 28C~, I forgot to edit it into the OP. (I was using CPUID HWMonitor for the cpu temps) And I read your guide, it was well written.
