Overclocking intel i7 4790k

[Zkye77]

Hello,

 

I decided to overclock my CPU and I got a result of 4.7 Ghz, 1.28V and cooling it with h100i.

 

Temperature is max is 90c under load. 

 

I am living in a desert and ambient temp here is aint pretty. 28c - 35c.

 

I did stress test it with Aida 64 and it is stable running for 20 minutes.

 

Question is the Cpu temp a good one? considering that i live in a desert.

I'd turn it down a bit for lifespan reasons, 90c is borderline of thermal throttling and that's not where you want to be

I would change your stock thermal paste to some MX4 or NT-H1

I would still lower that voltage and get to 4.6GHZ and 85 C maybe.

Try turning down the voltage a bit to see if you can get temps under 90C while still maintaining 4.7. If you can't just lower it to 4.6. You shouldn't see that big of a performance decrease.

Im turning it down to 4.6Ghz 1.26v and be stress testing it now and be back with the results 20minutes later

I'm back with the temp results running stable for 20 minutes.

 

Core #0 - 87c

Core #1 - 86c

Core #2 - 86c

Core #3 - 82c

Cpu - 87c

 

is this good enough?

Around 85*C is reasonable maximum. You should be ok but try to lover those voltages even more. You should play with vcore voltage, ring bus voltage (or cpu cache voltage) and vrin voltage. After you hit the limit you shoud test stability for longer period of time. Also try different workloads (AIDA, prime95 etc). Ideally you temperatures will oscilate around 80*C or less.

Im using aida64 and intel XTU for stress testing.
