Built a PC yesterday at about 10pm (GMT) went to bed, then went to work came back and thought right time to overclock CPU.

So I have my i7 4790k, Asus Maximus VII Ranger (Z97), 8 GB RAM 2133Mhz and a GTX 780Ti. H100i cooler

So my temps are fine when cpu is at idle - sub 30c, but as soon as it gets to about 80% load its at about 95c - 100c.

Im using Intel Extreme Tuning Utility to check, Temps, Voltages and Stress tests etc. I ve also got open CPUz and Open Hardware Monitor (just to make sure temps and they all say the same when at about 80% load CPU hits 95c to 100c.

Any help would be appreciated :)

Off to bed before work and then i will be back at about 2 - 3 pm (GMT)

Things to note :
This was an EZ Tuning overclock(Automatic overclock of CPU and DRAM on Asus Motherboard)
CPU Voltage is 1.27539063v
with no Dynamic CPU offset
Reference clock is 102.0071
CPU Multipliers 45x on all cores

Any help would be appreciated as Ive said:)

That is very hot!

Did you apply thermal paste & have you checked the block is seated correctly? I would expect it to get hotter quicker if not, but just to be sure.

Also, I wouldn't use the utility, I'd change the settings in the BIOS. Try setting the multiplier to x42, as a starting point, without adjusting any other settings and see how you get on. We can then go from there.
 
I reseated things today and it hits 80c now(no overclock tho) at 100% load so there's a small improvement. Still to high for me I wouldn't expect over 60c at 100% load. Or am I expecting to much? Could the cooler be faulty? My friend on monday is stealing some better thermal compound (only used what was already applied). Anymore suggestions while I wait?
 
are you using latest bios? 1.275v seems high for stock clocks,newer bios's reduce default cpu v

also set a manual reference clock of 100
