Safe temps i7 4790k

Recommended Posts

if that chip is 100% stable at 1.2v than you have one of the best chips from any batch. 1.2v is unheard of @ 4.7ghz. congratz

^ Very much, very lucky. 4.5GHz @ 1.25V's is average, getting 4.7GHz @ 1.20V's is pretty golden.That'll probably get you 5.0GHz or even 5.1GHz at 1.35V's under delidding and customer watercooling. If you can verify that, you could probably sell it for like $450 and just get an average one for $250, lol.

I was hitting throttling at 100c, at 4.8Ghz, 3.275v. I must say it got hot pretty fast.

For the time being running at 4.7Ghz, 2.75v, max temp at 100% load is about 70c-75, AIDA 64/Prime, Corsair H110 with 2x NF-A14 PWM.

How is that even possible ? wouldnt the chip instantly fry ? sometimes i get afraid to raise .025 haha

They key words are delidding and custom watercoolilng. Delidding will still give you around 15C - 20C better results at stock voltages. Add custom watercooling (pump, res, at least 120.3 rad, 3/4" ID tubing), and you can cut that down a lot more. At your overclock settings (4.7GHz @ 1.20V's), highest temp probably would be 54C, depending on your ambient temp. 5.0GHz @ 1.30V's would be in the mid 70's or 80's.

No, you need a lot more to fry a CPU.. You need to run it at max temp for quite some time at high voltage..

 

I've been running mine at 1.325v for at least a month.. It didn't destroy the chip, it might have damaged it's life span, but if you take into account that these chips designed to run for at least 10 years, then I wouldn't worry about it that much..

 

EDIT: typo fix.
