i7 4790k stock cooler

[Elitepro]

hello i install 4790k today with stock cooler temp is around 60c when i play games temp go near 100c is that normal? should i worry about that, i use turbo boost mode on always work on 4.4ghz what is highest temp for cpu can cpu be damaged if he goes too hot?

The 4790 is a pretty hot CPU. It is most likely throttling, so no need to worry about damage. Honestly I haven't even used the stock cooler on mine.

It won't get damaged. But, watch it with something like Coretemp, or log data w/ HWInfo64, and see how it is in terms of power use. If it is throttling from temp but not power, there is likely a bit of performance gain to be had from a better cooler.

I just wish how much is highest temp or danger zone with temp, i will buy h100i soon.. just want to be sure this temps is not danger for cpu hw monitor cpu package around 80 atm when i install games..

If you are worried, just return the CPU to stock settings and it should not overheat. Then when you get a better cooler you can return to faster settings.

I think the CPU starts throttling around 90. As crashtech pointed out, just turn off turbo if you are concerned.

Leave the throttling feature on, like it is by default, and there will be no danger zone to worry about. It will throttle itself, likely at 100C instantaneous, but lower over time.

Many things could be in play here. The motherboard may be giving the CPU more voltage than it needs, or the HSF may have a pin that did not insert properly into the motherboard. Games are not like LinX, they shouldn't be loading all cores 100%.

i turn off turbo mode and now temp is around 55 idle when i play games around 67 max was 71c

Still seems weird that turning off turbo brings load temps down from 100 deg to 70. Maybe the board was doing the enhanced turbo where all cores run at max turbo, and/or boosting the voltage?

Base clock is 4.0 and 4 core turbo is 4.2 I believe. Dont see how that small a change in clockspeed could lower the temps so much.

 

[Cerb]

Turbo on/off shouldn't be that much of a difference. Check what CPU voltages are being used with and without Turbo, when under load.

mine run hot with stock cooler but not that hot; 85C with pime95 and 60C with games. Idle temp is around 37C.

Several things.

I'm comparing notes per a Corsair C70 project on Cases & Cooling, which involves an i7-4790K processor. My Sandy Bridgers throw out about 140W-worth of thermal energy, and with "great" air-cooling, I can keep the most severe load test temperatures at an average below ~72C @ ambient 77F. By comparison, a superior approach with a single-fan AiO cooler can get down to the high 50's at near-stock 4790K settings. The thermal power of the Devils Canyon is about 88W.

Because of the smaller die size and lithography, we'd expect the temperatures to be higher for the 4790K even with a superior cooling situation. So my overclocked Sandy @ 4.7 will stress at maximum 72C. OC the 4790K just a couple hundred Mhz, and even with thermal wattage somewhere between 88 and 140W, the temperatures are going to be higher with the same cooling prescription.

The other thing -- it is beginning to look as if a lot of the Z97 boards use excessive voltage at stock settings: everybody who has fiddled with it to get full 4.4Ghz while watching the temperature sensors had to begin by dropping the voltage before starting to raise it in incremental steps.

The CPU will shut down before it gets damaged, I'd consider under volting it even. You don't need to over clock it, you want to keep it below 90C.
