Are the I7 4790K temperatures within acceptable ranges? (stock on OC temps)
Are the I7 4790K temperatures within acceptable ranges? (stock on OC temps)
I tried my first overclock on my PC built in late February. Here’s the link to the build: https://uk.pcpartpicker.com/user/dan_b_1...iew=3V9MnQ. Even with stock speeds and an AIDA64 system stability test, temperatures reached high 70s and low 80s. I’m curious if these are acceptable. I previously ran it at 4.6GHz with 1.22V and still saw high 80s and low 90s. Others with higher speeds and better coolers managed lower temps. I’m unsure what to do—should I upgrade the cooler paste or move the PC off the desk? Is it my CPU’s fault, or should I handle it myself? Any advice would be greatly appreciated. Thanks.
Increasing clock speed and voltage tends to lower temperatures for better stability. It's the mix of voltage and temperature that leads to CPU degradation. At regular speeds, a 90°C rise likely won't noticeably shorten your chip's lifespan, but higher voltages could have a more impactful effect.
temps are NOT ok.
You are running pretty high temps even on stock clock.
Yes it would probably be a good idea to re-do the thermal paste although... there is one thing to do before moving straight to that.
How's your airflow in the case? is ambient (room temp) high? near a heater? Did you configure your water cooler fans correctly?
also, you could download your motherboard software (utility), it's likely that the utility program has 1 click overclock to 4.6Ghz without playing with the settings in your bios (it will auto overclock with good stability)

Using the nzxt H440 case has only a side vent at the front but it has a sizeable gap from the wall and no radiators on nearby, the ambient temperature when the pc is off is about 18 but gets up to around 21 when the pc is on and the fans on the cpu radiator are set to full speed all the time through the msi bios so im not sure whats up. im probably going to move the pc onto the desk to give better air flow but having 3 monitors on the desk doesn't lead to much spear room. but thanks for your reply.
Change your stress test to OCCT. My 4790K is @ 4.6 1.22 volts and reached around 78C with a Cryorig R1 air cooler.
