Recenly i build a computer for myself.

Cpu : intel i5 9600k
Mobo : Msi z390 Tomahawk
GPU : GTX 780 Direct II CU OC
RAM : 8x2 Gskill Ripjaws 3200 CL 16
PSU : Xigmatek 80 Plus Gold 650 W.

My problem is i build this computer w.o a pc case. Everything is fine cpu is at 4.9 ghz at prime95 with 70-75 degree. Gpu is at 55-60 degrees at stress tests(default clocks, default fan speed)
Recently i got a pc case i put everything in to the case. Case was msi mag forge 101m. I tested cpu on prime95 its fine at 75 degrees but when i test the gpu its hitting 100 degrees in 10 second and shutting down the pc. I put fan speeds to % 100 on msi afterburner nothing changed. I try these parts on another nzxt case its same on that too. Want to know what can cause this strange heat issue.

Sorry for my bad English.

Sounds like your old GPU needs a replacement of the thermal paste on it. 100C inside 10 seconds with the fan at 100% is a GPU issue.

You're not overclocking it right?
Everything is default. Right now its i put everything outside of case Its have 50 degrees at furmark bench with default fan speed. Idk why its getting hot inside of case.
