Hi all...
The same problem here. First of all my rig:
Case : Supermicro 747tq-r1400b (for those who don't know - a server case with huge space and 6 huge 5000rpm fans tha sound like a jet engine )
CPU : 4790K (L4)
Cooler : H100i (with arctic silver 5 thermal compound)
Mobo : Gigabyte GA-Z87-UD5H (F10c bios)
RAM : Corsair Vengeance Pro 2133Mhz 16GB (2x8GB)
GPU : No dedicated video card
OS : Windows 7 Ultimate 64bit
My cpu with stock cooling and f9 bios was running 39-45 idle (room temp about 22c) and when on load ( AIDA 64, Prime95 or intel XTU) was hitting almost instant 100-101c going to throttling.
When i upgraded the bios to f10c i was getting i little lower temps about 35-36 on idle and still 100c when on load but i was getting there more slowly (about a minute).
I went out and bought an Corsair H100i. Now things have improved BUT not very much. I am getting idle temps from 25-28c and the CPU can hold better when on load going to 78-85c but in some instances skyrocketing again to 100c.
Someone can say that i have an almost perfect cooling solution (server tower with 6x5000rpm fans + h100i) but still having problems.
Final conclusion is that i don't care what is the problem of the CPU, bad batch? cpu TIM?. I have spent TOP DOLLAR for a CPU that i was planning to use with stock cooling (so no overclocking) and now i find myself paying more money for water cooling, just to have the CPU operate at normal temps 70% of the time. Worse of all is that i must spent time that i don't have.
The original thread started 21st of August and has been 2 months and still no official answer about the problem !!!!!
Shame on You intel
