[SOLVED] PC overheating

[alexvdm]

So, i have an old hd 6790, which goes up to 100° celsius (or 212° farenheit) when it is at 99% usage, and while idle stays at around 46-47° celsius, which is crazy, i also have a Syx fearless case (very rare case seems like), below i attached an image of my pc airflow, i have 2 120mm coolers, blue is intake,red is exhaust, yellow are components, case does not support any 140mm fans, btw, i already checked all things like thermal paste, it is pretty clean, also if i touch lets say the cpu cooler or the ram they are hot af, any ideas about this? i will try to tell you everything i can from what you ask me, sorry for my bad english, im still learning, thanks!

Describe the CPU cooler in detail.

Is it the original cooler that came with the HP from the factory?

If this is an Intel stock cooler, how sure are you that all 4 corners of the cooler are mounted correctly? That can be tricky.

Have you checked to see what applications and processes might be running when the PC is idling? Normally, you'd expect idle temps to be below 40.

As a cpu i have an Athlon x4 640, which im sure has the original cooler, i dont think the cause is over too much stress, i think it is because of an airflow problem, but im not completely sure

Cooler on the GPU lint and dust free?
Have you tried running without side panel?

i cleaned it around one month ago, it gets to 100° without the side panel, i dont even want to try with it

If fans are running and cooler clean then the only issue can be thermal paste/pads on the GPU.

"Cooler Cleaned?" can be tricky to answer on an older system. On yours, I suspect the cooler is a finned metal heatsink tight on the top of the CPU chip, with a fan fastened to the top of this. Even if this looks clean, check the structure of that carefully. Normally the FAN part is fastened to the Heatsink part with some screws or a couple of metal springy clips. You can remove the fan from the heatsink without disturbing the bond of the heatsink to the CPU chip. THEN you can see the heatsink clearly. I have seen many photos of heatsinks with substantial dust accumulated between the fins so that air flow does NOT remove heat nearly as well as it should. IF you see that you can use a thin tool to scrape the dust out to really clean, them replace the fan.

As a note, the fans in blue/red on the bottom are for the psu which has no part in ace cooling.
Your processor is not an overly hot one.
I think likely, your cooler mount is not good and the case air intake is insufficient.
What is your room temperature?
Idle temperature starts there.
If you take the side cover off and direct a house fan at the innards, does that help?
If it does, look to case cooling.
Either replace the front intake fan with one of higher rpm or look to a better case.

old hd 6790

Have you ever repaste that 10 year old GPU?

since i got it i change it always i clean it, so around once a month

You saying that you re-paste once a month?
