R9 390x 8gb temperatures
When running games like gta 5, and fallout 4, MSI afterburner displays my gpu temps at 95c, yet my game performance doesn't seem to suffer. I have 1 exhaust fan on the top, and 2 intake fans in the front of the case, the card is blower-style coming out of the back. I am still fairly new to building computers, and am unsure if i am doing something wrong.

i7-6700k @ 4.0Ghz (120mm AIO liquid cooler)
R9 390x 8gb
16gb DDR4 RAM

Exhaust fan is the stock nzxt S340 case fan.
Intake fans are Zalman z1 case fans i salvaged from a case i had lying around.

Please inform me if i am missing any info.

Temperature sensors don't always work correctly and applications that read temperature sensors don't either.

The highest i have seen my r9 390x 8gb xfx go is 79c that is while overclocked and it usually runs around 75c I also use MSI afterburner to monitor the temps you might have a bad sensor or something.

How cool does the air coming out of it feel? Mine tends to be pretty hot and heats on the case around it.

How often are they faulty? How can i fix this?

My pc has good airflow 2 fans in the front, 1 in the side that turns on when the CPU goes above 38c holes in the top to let hot air out. Warm air get blown out quite quickly.

But your card, it blows air out the back, correct? How hot does it feel?

Mine doesn't blow air out the back I have a XFX cooler on the card the air gets pulled from the bottom of the case by 2 fans and the air gets ejected to the sides of the card thru a heatsink. You have a reference card those things are notorious for having ♥♥♥♥ coolers.

I've searched this problem before online and i found a few people saying they are meant to run at this temperature, but i find it hard to believe that the card isn't suffering majorly from it, or that its even true at all.

You can't tell once it gets to a certain temp; 60*C is 140*F; so that and above is very hot when you consider how warm the air feels.

If you are hitting 95*C (according to monitoring apps) and nothing is crashing, slowing down, acting up, chances are that temp is reporting incorrectly.

They are not meant to run this hot, but most AMD GPUs can, sure.

Sounds like its time to improve overall case airflow, maybe disesemble the GPU cooler and clean it; and replace thermal paste on GPU core.

You have one of these[i2.wp.com] cards I have one like this[cdn.agilitycms.com]. Its kind of hard to compare the two.

On idle, it also displays fluctuations between 40-70c

People use the term idle very loosely though.
IDLE as in what? If your browser is open and you're idle (as in not doing anything) guess what, it's still putting a load on the GPU the entire time it's open. Turn off hardware acceleration in web browsers so it doesn't use the GPU.

I had nothing but msi afterburner open

Are the clocks slowing and going down in the very low Mhz? Whats called power saving or 2D clocks. If it's in the high Mhz area (3D clocks) then it's NOT idle.

What would be considered the low area? I saw it go to around ~500Mhz

Ok do this as a means of double checking what MSI Afterburner is reporting.

Download GPU-Z and run that, then click on Sensors, see what is actively going on in there.
