Hey there!

I've been helping a friend build his PC over the past few days and we managed to finish it night before last. Today, it turns out his idle temprature was sitting at 90+, and his fans were going ballistic. Now, he's turned off his PC to get it a little cooler as he rebooted and wasn't able to get into windows thanks to the BIOS's temp warning.

What we're confused about is the high temps. He's running (as the title suggests) an i7 4790k with a h100i cooling it. I've been searching around, and there's little info for a stock system that could possibly get the temps down, since everything comes up about overclocking.

The system:

NZXT FZ 140mm White LED Fan
Hotway External Slim DVD Burner USB 2.0
ASUS Xonar Essence STX
Corsair Hydro Series H100i CPU Cooler
Intel Core i7 4790K
Kingston HyperX 3K 120GB SSD
Western Digital WD SE 2TB WD2000F9YZ
Corsair Vengeance Pro CMY8GX3M2B2133C9R 8GB (2x4GB) DDR3
EVGA GeForce GTX 780 Ti Superclocked ACX 3GB
ASUS Maximus VII Ranger Motherboard
ASUS PCE-AC68 Dual Band Wireless AC1900 PCI-E Adapter
Silverstone Strider Gold Evolution 1000W ST1000G
NZXT H440 Mid Tower Case Black/Red

I'm running through some possibilities before he hops back online, but there's talk about the Vcore settings, as well as possibly an incorrect mount, malfunctioning pump, lack of intake/exhaust air. Is there anything a new user can do to figure anything out? Even basic steps (He's not that technically smart, this is his first ever build) on how it could be achieved?

Thanks for replying!

My suggestions to you:

1) Reset your motherboard bios

2) Since the H100i back plate is very loose buy some rubber/neoprene washers. (I used 5/64 inch ones with two on each peg) You'd put them on the back plate itself and then reattach it to the motherboard. I was overheating at stock speeds when I didn't have the washers on.

3) make sure you have even thermal paste coverage, and that the cooler is centered in the middle of the slots

4) when you screw the cooler down go diagonal corners when you tighten it, it makes the paste spread more evenly.

I hope this helps

First thing to do is press down on the pump/heatsink of the H100i where it is on top of the CPU. If this serves to bring the temperature down then you make a mistake in installing and mounting the heatsink on top of the CPU or in fixing it to the backplate.

If that has no effect, feel with your hand if one of the two pipes leading from/to the pump is warmer than the other. Also make sure the pump is plugged into the correct CPU-Fan header on the mobo. Listen if you can hear the pump. If the pipes aren't warmer, and the pump is mounted correctly on the CPU, possibility exists that you have a defective cooler.

Use the stock cooler to test of your CPU can be cooled with that.

Update: He's currently looking to see if there's a problem with the pump or anything. So far, the pump cords feel correct with one warm and cold. He tells me that it worked without fail yesterday and he was even gaming on max settings, but now the idle is sitting at 90-100 degrees. I've told him to change to the stock heatsink and he just wants to be sure that it's a problem with the h100 since it was a hassle for him to mount it.
