i7 4790k Temperature Question

Rear Bumper · Dec 15, 2014

Hello, I have a question about my processor temps. Consider myself a novice in this area, as this was my first PC build and was about three months ago.

My CPU idled at 34 degrees Celsius when I first started it three months ago, and recently I heard the cpu fan begin to spin a bit harder a little more often, so I checked what it was running/idling at-

It seems to be idling around 42-43 degrees Celsius now, but oddly enough (And this was my first time testing it under stress, so forgive me if I did it wrong) seems to only get to about 48 degrees under full load.

This is a picture of my stress test

and my complete build

Asus LGA Pro Wifi-ac Motherboard
16gb 2133mhz G Skill Sniper Series RAM
Intel core i7 4790k Haswell 4.0ghz w/ Arctic Silver 5 (Cooler Master 212 Plus)
250gb Samsung SSD + 2tb WD Green HDD
EVGA Geforce GTX 780 FTW GPU
AX860 Corsair PSU

All in a Xion XON 985-bk Case (Two front 120mm case fans, two top 120mm case fans, and one rear 120mm case fan)

What is your question?

Are you worried because your CPU temps are below 50°C under stress?

Are you using the stock CPU cooler or did you install an aftermarket one?
Your temps are also depending on your CPU fan settings in the BIOS.
You could have a more silent profile that allows higher temps but lower CPU fan RPM (or you could do the exact opposite).
Are you happy with your system performance and level of noise? If yes, don't touch anything.

Mostly I'm worried if everything is right! I don't think my processor should be idling as high as forty, but nor do I think that it should remain as low as 50 under full load.

I've tried looking this up, and most people say a quality air cooler averages around the lower 30s- right where mine was when it was freshly installed; but they also say it can get into the upper 70s under full load, and I'm wondering if I'm not doing something right?

Check to make sure your heat sink hasn't picked up dust and all the mounting pins are correctly locked in and haven't come loose.

Rear Bumper,

Intel Processor Diagnostic Tool does a poor job of stress testing. There's a valid method to test your processor at 100% workload as well as at idle that will give you a thermal benchmark.

Also, what is your ambient temperature?

What valid method should I use instead?

Also I don't have access to a thermostat in the college dorms I'm currently residing in, but I do believe it is a standard 70 degrees Fahrenheit. Possibly a little cooler in my room with the window open, but not by too much.
