clock for clock an I7 will run a fair bit hotter tan an I5 when the software is running 8 thread on 4 cores. the chip does more work and logically gets hotter. Hyper threading does cause more heat to be generated. which is way it dosnt need much vcore voltage. with all 8 threads being run balls out a 4790K aint a cool chip. I think the max vcore needed for a 4790K at 4.4 would be 1.25. my system is now running 4.5 gig at 1.22 vcore its also showing 24 C while i type this. for what it called a mild 4.5 gig overclock it ramped the vcore up to 1.35 way too high. i tried the gigabyte stuff that came with my board. these auto clocking things tend to do that if that is what is being used. i would run the furmark gpu test at the same time as its cpu burner but the furmark gpu test needs a little more cpu grunt to run than heaven which in reality needs bugger all cpu grunt. to test total system heat i run the heaven benchmark and the furmark cpu burner at the same time. I simply leave the furmark burner running whilst browsing and doing other stuff for cpu heat and basic stability checks. it can also be run several times if one run isnt enough. Wprime on its on its longer test makes a good quick tempt check. it runs maybe one or two C hotter than wprime does. it has its own cpu burner as well as the gpu burner. My favourite heater for both graphics cards and cpu is furmark. my graphics cards for example take a good five or ten minutes to slowly ramp up to maximum tempts. its all down to other stuff slowly warming up. it soon drops back down as well.Īny significant heat after that has bugger all to do with the cpu. To be honest a cpu soon gets within 2 C or so of its maximum temps when air cooled. but then again i also noticed that in real world gaming and the like disabling HT made no difference. Super PI 32m: 6m 42s 472ms thought about disabling HT on my 4790K to drop the tempts whilst running daft things like prime95.
