Up to 90ºC on the core and unknown at the VRMs? No risers, no undervolt, no space between cards, accumulating dust?
Understand: you must do _something_ to fix that problem. Not saying that it's ok now, and hope. You're degrading those cards fairly quickly.
Being "maxed out" or not is barely relevant. That "maxed out" is for casual use of the devices as intended (e.g. a few hours a day with 3d gaming loads), not 24/7 mining with the conditions above.
How do I calculate/finout the VRMs ?
I believe 750 for 280x is normal without needing to be undevolted . is it not ?
for 7950 yes I did overclock it to get 650 but that too would be taken care of by the psu which has enough power isnt it ?
The cards have some space between them and with the fan running constantly they are about 80 C for the past few days . now without overclocking it is at about 77-78 currently. The dust part was normal house dust that had accumulated (living tropically).
About these cards 24/7 .. people do it for months together without any problems isn't it ? So mine is just a month old .
And how is one cards overclocking affecting others ? I fail to understand
