Hello
I have this system:
-Motherboard Asus Maximus VII Hero
-CPU Intel Core i7-4790K 4GHz 8MB Sk1150
-Water Cooling Corsair Hydro Series H100i
-GPU Asus GTX980-4GD5
-Memory Kingston HyperX Savage DDR3-2400MHz 2x8GB
-PSU Corsair RM750W
-SSD Samsung 2.5" 850 Pro 512GB
-SSD Crucial MX100 256GB
-HD Western Digital Passport Essential SE 2TB USB3
-Case Obsidian 550D
-Sound card Asus Xonar Essence STX II 7.1
-Monitor Asus 27" 144Hz VG278HE
My room temp is 14ºC (57.2ºF).
The air cooling in my case is set like this:
-1 stock Corsair Case fan, on the front, in air intake
-1 Noctua NF-S12A Case Fan, on the front, in air intake
-1 Noctua NF-S12A Case Fan, on the back, in air exhaust
-1 stock Corsair Case fan, on the bottom, in air intake
-Water Cooler Corsair H100i, on the top of the case, in air exhaust
The termal paste used on my CPU to mount the water cooler was Artic Silver 5.
I had 37º C (98.6 º F) on iddle,

(v core always on 1.25V, on iddle, with default settings. I don't know why. SpeedStep is enabled on bios.)
76º C (168º F) was my full load temp, using Intel XTU Stress Test.
Then I saw ken-intel thread,
Troubleshooting Intel® Core™ i7-4790K / i5-4690K overheating
And made the manual changes as describred in his screenshots, on Intel XTU,

(CPU Core Voltage always on 1.15V, does not go down, even on iddle, still don't know why.)
64ºC (147.2ºF) on full load, using Intel XTU,

(Processor Frequency went to 4.4ghz before, now It only goes to 4.2ghz max)
My friend's config with the same CPU, Motherboard and Memmory:
-Intel Core i7-4790K 4GHz 8MB Sk1150
-Kingston HyperX Savage DDR3-2400MHz 2x8GB
-Motherboard Asus Z97 Maximus VII Hero
-PSU Corsair Builder CX750W
-Case Carbide 200R (CC-9011023-WW)
-Water Cooler Corsair Hydro Series H80i
-SSD Crucial MX100 256GB
-GPU MSI GTX970 Gaming 4G
Very similar to my desktop, but with,
-Water Cooler Corsair H80i, instead of my H100i
-2 stock case fans, 1 in front, in intake and another on the back of the case, in air exhaust. I have 4.
-Case Corsair Carbide 200R. Mine is Corsair Obsidian 550D.
My system should have better temps than his, but it does not.
He has:
25ºC (77ºF) on iddle,

54ºC (129.2ºF) on Full Load, using the same Intel XTU program, with same CPU, Motherboard and Memmory.

I have a few questions,
-Why is my CPU Core Voltage always on 1.15V even on iddle? How can I change this? SpeedStep is enabled on BIOS.
-Before my CPU Processor Frequency went to 4.4ghz. How can I make it go to that level on full load again, without raising temps too much?
-Finally, what do you think of my CPU temps? Are they good?
-What should be the reason for my friend's temps, with the same CPU, Motherboard, Memmory, be 11ºC (51.8ºF) lower on iddle, and 10ºC (50ºF) lower on full load? (he has stock thermal paste)
-Are there any changes I can manually make for my motherboard Asus Maximus VII Hero, on Intel XTU, that could give me better temps?
Best reggards,
