Hi all - I have a cooling question for a media PC that was recently put into a cabinet in our living room. It gets extremely hot, but all temperatures report well under 90c. Does that mean it's fine, or should I still be worried?

The computer is in a small case that is pretty much filled to the brim, but has always managed decent airflow. i7 4790k, not overclocked; Nvidia GTX 780 GPU, not overclocked. CPU is cooled with a corsair liquid cooling system that vents out from the top. Been running it a few years and it's never had issues with overheating.

We recently remodeled our living room and now the PC is in a cabinet. The exhaust vent at the top is only a few inches from the roof of the cabinet and the whole thing now gets extremely hot to the touch. Not painful, but very, very hot. I've run Openhardware monitor to view temps while gaming and it looks like the CPU cores top out around 79c. GPU tops out around 82c. My understanding is that temps under 90 are fine, under 80 are warm but ok, and anything under 70 is considered cool.

Is it safe to operate like this, or am I doing damage to my system? Just looking at the numbers, I would think I'm fine, but the thing is so hot to the touch it's hard to believe it's not bad for it.
 
I looked up the temps for your cpu and it says the Thermal Specification is 72.72 °C. The max your gpu can get is 95 degrees Celsius. So from the sound of it you are doing some damage to your computer. Try taking it out of the cabinet and if its still hot get a new cpu cooler.
 


Thanks for reaching out! Can anyone verify this? It seems to contradict what I've read about temperatures from many other sources. I know there are different ways to measure operating temps, so I'm wondering if there is something I'm missing? I've read way too many people saying things like 90c is hot, but safe, to not at least question it.

Thoughts?
