i7-6700k with hyper 212 EVO temps

[Peter Boyle]

What temps can I expect to get with the i7-6700k (no overclock) with a hyper 212 EVO? Is it worth getting the corsair h100i v2 to allow Overclocking in the future?

 

thanks

You can oc on a 212 Evo. 

Depending on the fan speed, 60-70c at load is normal.

 

Moved to Air Cooling.

no OC and depending on the ambient, the CPU at full tilt should be in the 40-50deg range

 

highly optimistic on my part

The 212 EVO itself already allows for some small OCing, so getting the H100i would be for pushing the CPU hard. If you can afford it, I suppose it's worth the investment.

No, that is ridiculously low. Unless the computer is in a freezing cold environment, those kind of temps shouldn't be attainable without something along the lines of a custom water loop with large rads.

"normal" ...

max T_case for i7-6700K is 64deg

I based my assumption on tests done with 23deg ambient, but yeah ... I guess it's little too optimistic considering it's a 91W TDP CPU

Tcase is for the ihs and isn't the same as core temps. Core temps will normally be higher.

what now!?!? max T_case doesn't mean IDLE

Case Temperature is the maximum temperature allowed at the processor Integrated Heat Spreader (IHS).

CPU will start to throtle at 80 to 100 degrees. Like @WoodenMarker said. You are referring to the wrong number

the diff from core and T_case is just few deg - and greatly depends on the TIM application between the die and the IHS

Extremely optimistic*

Here's a h110i GT keeping a stock 4790k at 56c load. http://www.guru3d.com/articles_pages/corsair_h110i_gt_review,10.html

In order to deal with diminishing returns, considerably more cooling would be needed for <50c.

isn't TJ max like 100 degrees before throttling?

It's 105c.

at 100deg that CPU will start to destroy itself

people have done X-rays of OCed dies and found microfractures

It's been a while since I had a 212 on a 6700k or 6600k, since I run prime95 like loads and HT makes no difference between them. From memory I think temps were in the ball park of 70C with at 4.2 GHz 1.25v which is what I found mine to be stable at. Room temps in low 20's. I've moved them onto bigger/higher end units and it makes a bit of difference, but the 212 wins on value.

You can hit 100C without OC e.g. dust on heatsink, or other restricted airflow, or simply being under-designed like most laptops. Built in thermal throttling isn't just for OC.

you should not rely on thermal throttling to keep that CPU "safe"

 

Silicon is a metal, and like all metals it will contract and expand with the degree of temperature it's at - these repeating motions will destroy the CPU in time

it's not only the die that's directly affected by the temperature, the ISH, the microbumps between the die and the interposer

 

just the other day (or so), PCPer said their 2011-v3 Broadwell-E CPU doesn't OC like it used to, and those CPUs aren't even 1/2y old

Temperature alone is not the only stress factor leading to a reduction of life. Voltage also plays a part although it has been a while since I looked at it.

 

I'll admit I've not followed in detail all OC over the years, but I don't recall of any significant OC related life reductions since SNDS era.

Silicon isn't a metal, it is a semiconductor. If it were a metal, it would be a lot less fun. Pretty much all materials change density with temperature. If thermal stress were a major problem, laptops would particularly feel the stress, yet they generally survive regardless.

to be technical,

Silicon is a metalloid - it has properties from metals and non metals, that's why they're called semi-metals or semiconductors

Still not a metal.

Totally agree with you. I got my 4790k with a Hyper 212 Evo and in a gaming load at 22C ambient loads at 60-70C.

How much you want to OC? If you are going for highest possible clocks, or just want to boast with beefy cooler, H100i will be better choice. I'm air cooler guy myself, so I would pick dual tower instead.
