Howdy great peeps,

Before changing anything in the BIOS, at stress test it got 59c maximum.
With all power saving options etc disabled it becomes about 72c - NO overclock yet..

Are these temperatures safe? I intended to do overclocking but it seems out of the picture.
However, what ARE safe temperatures for the I7 4790K?

I read that Intel says 72c, on the forums some say 65c, & others say 80c ..

Hoping for a quick response,
Mike

The maximum junction temperature on Ivy Bridge was 105C but Intel reduced that a bit for Haswell, don't remember if it was 98C ot 102C but if you are going to overclock, you obviously do not want to get anywhere near that.

80C is a generally safe core temperature but at the upper end of what most overclockers feel comfortable with.

Less than 70C core temperature under load is a safe area many OCers like to be in - very low likelihood of causing any damage to the chip.

The 72C you read is the max package (IHS) temperature.


I have a de-lidded and watercooled i7-4790K overclocked to 4.7GHz at 1.273v that gets 83c max temps running Intel burn test on standard 25 times.
 


The problem with fixing your voltage, although that's the best way to get the higher overclock, is that it will not power down when the workload goes down. It stays at 4.6 or w/e. It's very inneficient, but if you're just going for that point score then you're fine with that.

I hit 4.6 stable with fixed voltage, but I need adaptive because most of the time I am not gaming or using BOINC. So why damge the chip and waste electricity when web browsing is beyond me. 4.6 oc with adaptive is fine.
