"ReVenge Gigabyte Z97" Intel Core i7 4790K @ up to 4.6GHz Configurable Enthusiast Gaming Bundle

Asetek 570LXL 240mm High Performance Liquid CPU Cooler - 1150

TeamGroup Vulcan ORANGE 16GB (2x8GB) DDR3 PC3-17100C11 2133MHz Dual Channel Kit (TLAED316G2133HC11ADC01)

Intel i7 4790K - 4.8GHz Binned

This was bought from Overclockers in February 2015, had issues ever since with game temperatures. I bought extra exhaust fans and never managed to fix the problem, reapplied thermal paste, resat the radiator, made sure the AIO liquid cooler was actually working. I just gave up in the end and learnt to accept that the 4790K runs hot and that my temperatures would always be higher until the day I upgrade. 25-30 idle temperatures which then creep up to 80-85C when gaming.

That was up until recently when I stumbled upon a forum post by another user on another forum with a 6700K talking about stock Intel voltage clocks and how they were ridiculously high causing huge temperature gains in his rig. So I did a little bit of digging and found that my max core voltage when in a video game is 1.231. At idle the core voltage says 0.803V through CPU-z, It does flutter around the 0.8 to 1.0 range with applications open.

I left everything in the BIOS at the default settings when it all arrived, not touched anything. Could somebody please help me fix this issue :). The cooler as far as I'm aware is still working, I have enough intake (3) and exhaust fans (3) inside the case. With the AIO and RAD also.

I seem to have found the issue. It seems to be the case itself restricting outgoing airflow :(. http://www.overclockers.co.uk/showproduct.php?prodid=CA-151-NX I have taken the top panel off and the cpu temperatures are now down to 50-55c when gaming.

Would it be safe to leave the panel off for a while? I may also look into buying a new case in the near future any ideas?

As for increasing the Pump / fan speeds it was too way too confusing to follow with tutorials.
