Question Sapphire Nitro R9 380X 4GB Thermal problems

[jubul]

Hi to everyone, around two months I buy a R9 380X, and today, viewing the temps, I see an unusual temps, 45ºC Idle , 92ºC playing FarCry 5. I change the thermal compound and the temps go down only 2ºC. My Specs are: i5 4440, 16Gb DDR3 HyperX, 240 GB SSD HyperX, 750W 80 plus Thermaltake PSU, Thermaltake Versa C23 TG.

If someone can give me a advice, I'll waiting. Thanks.

PD: Sorry for my bad English

Whats your case ventilation?
Have you tried with open sidepanel?

Does the fans ramp up on gpu?
You can manually do that in amd global setting/overclock or msi afterburner and ramp up to 100%

I have one Thermaltake Riing cooler getting out the hot air and two riing upside putting the cold air of my Air Conditioner. The coolers are working at 100% always, and the temps are the same. I remove the tempered glass and still hot. I've thinking, when I change the thermal compound, the backplate was move several times, maybe a bad position of the backplate can give me those thermal problems?
