^^ please dont misslead the information, you'll be fine up to 95c
, and your card shouldn go above 40c load, yours is very hot if it hits 80c
,.. mid to highend card runs hot
it comes to personal preference
, i wouldnt mine running my card as high as 90-95c, but, only if its under very stressful load (furmark/kombustor). I have enough experience with ATI/Nvidia gpu, since X1650/FX5700 until ATI 48xx and geforce 4xx generation, and those are damn hot card
,... run my 4890 in backup rig ~90c for years, still rocking..
90-95c for a stock cooled gpu is completely fine, no really, absolutely ok, just read online review, they have like 75-85c on their test bench, its open, imagine if its inside a case
but,.. the issue with 90c gpu is that it will produce heat to its pcb's and spread it to the rest of your component, you wouldnt like hot air goin around inside the case either,.. so airflow is very important
,.. my max cpu load with IBT is 67c, but when i game, it goes as high as 74c
, blame the gpu.
and keep watching on your VRM, will go 120c in a blink of an eye
, if not cooled properly.
