I just put together my new build,
i7 4790k with an asus maximums vii formula and a h105 corsair cooler
idle temps are 35-40 while under load they sit at 87-90.
Should i be worried or is it normal for intel chips to run hot? My amd sat at 25-30 idle and high 90s under load.
*edit* I forgot to mention i use real temp to monitor and ran stress tests using prime 95

Do NOT run any versions of Prime95 later than 26.6. Here's why:

Core i 2nd, 3rd and 4th Generation CPU's have AVX (Advanced Vector Extension) instruction sets. Recent versions of Prime95, such as 28.5, 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...

i might actually.

quick image of where everything is plugged in, double checked the cooler one screw was a little loose running prime again and rt is saying 77-87 now

If 77-87C is at load it is better. But only the 77C part. 87C is too warm. The rad fans are in the right spot. The pump is OK... Do you have a fan header for the pump that isn't 4 pin? It should be alright as long as the header is set to full speed in BIOS. Usually a 3 pin fan will always run at full speed on a 4 pin header anyway. If you have a adapter to plug the pump into a Molex from the PSU, you might try try that.

But I have a feeling the temp is high at load due to mounting issues. You didn't remove the pump and re-seat it, did you. That will introduce microscopic air bubbles into the TIM that will retard heat transfer. Make sure the thumb screws on the pump mounting are as tight with finger pressure only. Don't leave any looseness to the thumb screws.

No haven't removed the pump although i could pull it off and clean it and re apply some artic silver instead of the corsair paste.
Also cpu pump is a 4 pin connection still work better plugged into a 3 or a molex?

If you haven't removed /replaced the pump, leave it as is. The stock TIM is good stuff too.
The Molex adapter was just a thought in case the PWM signal is affecting the pump RPM. But it's a long shot. My little Corsair H60 in my sig below was also on my hot FX-8350 @ 4.6 GHz and never got anywhere near 80C. On my i5-4690 it is cooler than that. So, that's what makes me feel the mounting isn't quite right. If you can verify the mounting is proper w/o removing the pump from the CPU, do that. But yes, if you must remove the pump to double check the mounting, then you'll have to clean/replace the TIM.

But to answer your initial question, no Intel chips run cooler than AMD. They are very low wattage efficient processors.

Allright, i'll double check it tomorrow after work, odds are i screwed up something,ill update after reapplying some new paste and give it a break in to see. If it runs any cooler

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.

Please download Prime95 version 26.6 - http://windows-downloads-center.blogspot.com/2011/04/prime95-266.html

Run only Small FFT’s for 10 minutes.

Your Core temperatures will test 10 to 20C lower with v26.6 than with v28.5.

Thanks,

That's excellent. I forgot all about that Prime 95 issue. I should have remembered that.
** Thanks to Computronix for the reminder. **
And I even rolled back my Prime95 to ver. 26.6 way back when that was discovered, only to completely forget about it now. My apologies for not catching that.

70F is close to 21C. I always ask because ambient temperature can be a huge variable.

We have people who are running their rigs in ambient temperatures anywhere from 10C to 35C.

Standard Ambient temperature is 22C, which is normal room temperature, and is the reference value for Intel’s Thermal Specifications. Knowing your Ambient temperature is important because Ambient directly affects all computer temperatures.

Intel's Thermal Specification is "Tcase", which is CPU temperature, not Core Temperature. Core temperature is 5C higher than CPU temperature due to sensor location.

Tcase for your i7 4790K is 74C. Tcase + 5 makes the corresponding Core temperature 79C.

The relationship between Core temperature and CPU temperature is not in the Thermal Specifications; it's only found in a few engineering documents.
