Hey guys hopefully im posting in the right place i have delided (razor method) my 6700k, two tiny scratch's of pcb ( put nail polish over) ( mx-4 line method for chip, x method for heatsink(hyper 212x) This is my first -Delid -heatsink install -thermal paste application -soon to be overclock Comp for past 4 days with heavy game use reaching temps of 58-63'c (stock 4ghz) however at idle the temp can spike from its normal of 35ish to 55, which is consistent with a larger observed workload at the time of the spike. (ambient temp of 24-34'c) my stock voltage on core temp and cpu-z reads 1.1998 even when in a game at 90-100% cpu loads the voltage doesnt change it fluctuates more readily but stays the same average. today i have turned on my gaming boost in bios( msi pro carbon) which set cpu to 4.4ghz at 1.35v. idle temp is same as stock, however a quick 50% intel burn test the cpu reached max 66-75'c or 3cores under 69 and one core 75. the voltage however reads on core temp 1.2005 but on cpu-z reads 1.312 and through the burn test the reading's didnt change by more than 0.0005volts for both programs. my Questions -temp fluctuations at idle have i used to much/less thermal paste or bad heatsink install? -variation in temp of cores in terms of max temp reached can be 9c diff is it normal? -which program is best to trust for cpu voltage readings? -how does nail polish fair with heat from cpu? -if my voltages really havent changed with the boost why the jump in temp to 75'c? -has anything i have posted so far seem consistent with something potentially wrong..? Thanks guys- full pc modding overclocking noob Update today also on 4.4Ghz few hours of gaming 90-100%cpu loads temps came in at 70-76 also tried 4.4 on stock 1.2 volts and it passed with max temp 65ish, currently on 4.6Ghz at 1.275volts highest spiked temps 71-78 ( most around 72) i did try 4.5 on stock voltage and failed 15mins into a test. Update2 turned cpu fan onto auto 80-100% it was on stock setting of 40% with above tests and gaming at 4.7Ghz voltage 1.320 average temp=62 max temp=68-76( always core No1 hotter than rest!) cpu load 90% 15mins at 4.8Ghz voltage 1.340 average temp= 65 max temp= 70-79 cpu load 90% 15mins for my working overclock i was hoping to get temp spikes less than 85 with voltage less than 1.4 with unknown Ghz. i dont really know what to make of my result so far...?
