I have an Intel Core I7 3770K CPU placed on a ASRock Z77 Extreme 6 Motherboard and with Corsair Vengeance 4 x 4 GB 1866 GHZ 1.5 V Memory.
The case is cooled by 2 x 120mm 800 rpm fans pulling air in from the front and the cpu is cooled by the Antec H920 Water cooling system with the standard fans replaced to some silenx pro 120mm fans with high air throughput. Thermal compound is arctic mx4.
Room temp is arround 22C
I think this setup should give me quite good cooling, but still my CPU runs at 76 C when tested with AIDA64 at 100 % load for 20 min.
My idle temps are 30C on cores 0,1 and 3 while its 38C on core 2.
Full load core temps are arround 70 to 76C, but always core 2 as hottest one.
When reading other posts on different forums my cooling solution should give me atleast below 60 and for some people even below 50 in full load.
I have reinstalled the CPU 3 times now, once i also tryed the new box cooler with the thermal paste that was already applyed to it in the box, and that gave me load temps of 89C. I am perfectly sure that the coolers both were installed correctly and that the thermal compound was applyed as i should be ( I could see each time i removed it that it was spread evenly on the IHS of the CPU and covered it.
Should i be concerned at those temps ? Do i have a bad chip that i should replace ? How come some people with almost the same setup as me get temps that are 20C lower then me running the CPU at the same spped as i do ?
I spend extra money on this 3770K version of the cpu hoping for some Overclocking, but with my temps i dont think i should.
Please intel let me know your commends
1. Can there be big difference between the chips of the same CPU model, so that some run up to 20C cooler then others under full load and same conditions or is this caused by my chip being bad and i should return it for another one ?
2. What else could i try to get lower temp or trouble shoot why my temps are so high. I know fore example that the liquid in the Antec H920 is 40C when the cores on the cpu are at 76C. Can that be used to tell if i loose too much heat between the heatsink of the water cooler and the CPU ?
Hope to get some suggestions on whether i have bad CPU or if there is something else i could try to do with my setup.
