i am used to keep my case always open but i noticed the vga and other components werent performing as they should, now i closed its doing better than expected. but the vga cooler is making an annoying noise at lower speeds, what might be the cause? thanks

It seems that your GPU became accustomed to having the case open. Now that you closed the case, your GPU is claustrophobic and is screaming for you to open the case again.

haha its not the issue, i only closed because the annoying noise started happening more often, the performance bonus was a surprise.

plus the damn cooler doesnt turn off anymore, even with case open. i just spent a week without using the pc, now this fking noise doesnt go away unless i turn the fans up to 63%
