is R9 200 series temp 94C causing PC crashes?
XFX Radeon R9 290X R9-290X ENFC 4GB 512-Bit GDDR5 PCI Express 3.0 CrossFireX
so here is the issue, my PC (windows 7) started crashing intermittently: complete lock up have to power down.
sometimes will not restart (goes through cycle of repeated fan/lights on then stops).
recently it just completely shut down on its own.
occurs more frequently when gaming, but not exclusively.
local computer store installed latest graphics drivers and "stress tested it for 48 hours" on high graphic settings. found nothing wrong (checked hard drives).
thinking it's bad power supply but called dealer (cyberpower), support had me run CPUID HW monitor
shows graphics card temp ~70C idle,
when gaming (world of tanks >120 fps high-ish graphics settings), the card fan turns on and temp goes up to 94C
cyberpower support said the problem is graphics card, but it appears a number of cards run this hot
HW monitor also shows mainboard temp 100C
some forums suggest this may be a spurious reading
scanned with IR camera (below) measuring temps ~80C on hottest part of graphics card
nothing over 55C on the main board, suggesting this may be spurious.
so do i buy a new power supply or get a new graphics card under warranty?
edit power supply is corsair RM 850 plus gold
thanks for reading this far
main board hottest part:
