Stable i7-7700k temps @4.7Ghz?

Twistedwheelbarrow · May 4, 2017

I don't overclock often and I'm not really a nazi when it comes to ensuring the voltages are pristine and whatnot. It's at 4.7Ghz, 1.344 is the voltage it'll max out at when under load.

I was just curious as to whether 71 average whilst under load (playing playerunknown battlegrounds) is fine? I've only just put new paste on, so I imagine it'll settle down, but I'm really shaky when it comes to temps, that's all. It's about 30-35 idle, maybe 40 max.

The CPU will operate up to 100C or so, Anything below 80C is perfectly acceptable for everyday use.

I'm slightly surprised by the voltage required to only tack on 200Mhz, but the safe every max is around 1.4.

Eximo :

I think I might need to re-seat to be fair. It's very unstable right now temperature-wise. I mean it's idling at 30-40 but it just randomly ramped up to 71 then went back down.

CPUs will do that. If you have left all the power saving features turned on you should be seeing the voltage drop down to .7 volts or so, coupled with no load, that is your idle temperature.

To ramp up to 4.7Ghz it will increase the voltage. Each transistor that is pathing to ground will increase the current draw, and thus temperature, so the more work it does will increase the heat. In effect you can think of every transistor as a tiny resistor, when they are operating each one is dissipating a little heat across its junction.

Nice one. Dropped it down to 4.6 because I've always been really OCD about high temps haha. Thank you though, that really helped.
