Question HELP ME PLEASE

[ridwan123]

i Just change my pc case today because my 7900 xtx cannot fit my previous case.somehow i was shocked because when playing games with 7900 xtx the moment when i touch the new case glass it is very hot like burning,i was so confused and scared that i dont want to play the games but somehow i record that my gpu temperature is 75 degree and hotspot is in 95 degree.my previous rtx 4070 super with the previous case get 81 temp(not hotspot) in most game and when i touch it that not too hot

I just got a new problem today when i put the new xfx rx 7900 xtx magnetic air my cpu become so hot while playing cpu intensive game like dota 2 ,cs 2.i dont know why this is happening it is because of my cooler or the new configuration or what

What video card did you have the new card is probably putting off a lot more heat.
Not enough airflow in the case and/or inadequate cooler can cause that.

List all your parts including the case and CPU cooler.

One post please making more gets things confusing.

when i touch the new case glass it is very hot

The TL;DR: It's physics. Glass insulates heat energy, and a 7900 XTX uses more power than a 4070 Super.

The gpu's finstack is pointing at the sides. Waste heat is blowing out towards the sides of the case. The glass panel is consistently being hit with heat energy from the gpu and absorbing some of it. The more energy it absorbs - in watts - the hotter it gets.

You can vertically mount the gpu(if the case supports the option), get a case with a steel panel instead, or simply not worry about it and don't touch the case during play.

It is still safe if the glass too hot?

The glass is far from being 'too hot'. To even make glass takes several hundreds of degrees, and the tolerance to heat is similar.
What is a problem is that glass doesn't handle rapid temperature changes well, which doesn't occur in normal cases.

It is safe for my component gpu?

That case looks like it has a glass front so very poor airflow also the hyper 212 is not enough cooler for that processor.

THe only real problem is only the glass panel that facing towards the gpu is hot ,the upperside glass which is the cpu and the cooler when i touch it not hot.i and maybe tomorrow i need some optimization on case fan because i cannot set to full speed in bios show zero rpm

I assure you, it's not a problem, unless you go and apply cold compress to the glass repeatedly; glass doesn't like rapid temperature change. Glass needs to be at 300C or more(depending on the materials used to make it) before it becomes a problem.
Just don't touch the glass while you're playing or right after you've finished.

Well, the cpu cooler's heatsink isn't aimed at the glass.

Well ok ,i think you are expert and i have one last question for you.do you know why my cpu gets too hot after changing GPU

SPEX
I7 14700F
XFX RX 7900 XTX MAGNETIC AIR
MONTECH CENTURY G5 850 W
16×2 CORSAIR DOMINATOR 6000 MHz

COOLER MASTER HYPER 212 LED COOLER

it touch near 100 degree during cs 2 and 90 degree during dota 2,my previous gpu 4070 super cpu do not get this temp

The cpu cooler doesn't just deal with the heat energy coming off the cpu. The 7900XTX is dumping more heat energy - some of which passes through the cpu cooler - inside the case than the 4070 Super did. That means higher case ambient temperature, which affects min & max operating temperatures for all your parts.

The Hyper 212 isn't suited for large(er) heat loads. Depending on the engineering of the cpu, 120~150w appears to be cooler's limit.
Using hwinfo, see how much package power(watts) the cpu is drawing during the game.

In the roof of the case, is there a fan(s) in front of the cpu cooler? If so, the fan(s) would be pulling cooler air out of the case before it could pass through the cooler. While removing them would be an option, gpu exhaust wouldn't get drawn out as fast.
It's a bit of a catch 22.

For cpu cooler, you may look into a thermalright phantom spirit cooler. It's a dual tower cooler vs single like the 212. If you don't have fans on top, you might see if you can install of fans on top as exhaust. You could try them as inake as well. Maybe it would be worth putting 2 up there as exhaust and switching the rear fan to being for intake so that cool air comes in and hopefully hot air goes out the top.
