Hello there,
I used to have crossfired HD4870X2 on which VRMs tend to overheat to 120°C and then system just shut down, monitor went black and PC off, after few secs it started booting up itself.
I managed to "solve" that by mounting powerful fan (100CFM, noisy as hell) to the side of primary graphic card - it was very noisy, but I could enjoy my games.
Now I faced opportunity to upgrade, so I sold both HD4870X2 and installed one Sapphire HD5970 4GB, hoping to get rid of the noise and gain a bit of perfomace. God I was wrong.
It was all nice etc. but from time to time I experienced the same - sudden shutdown of system out of nothing, rebooting few secs after. Then I found out I had turned my 3x120mm front case fans to minimum, turned them up and it didn't happen since then.
Yesterday I installed Lost Planet 2 looking for some graphical orgies (couldn't get to run DX11 - I just got "... stopped working" when menu was supposed to show up), ran DX9 mode and started mission - system shutdown during intro, I've manually set fans to 100% before starting game, GPU was 38°C, CPU 22°C.
I've tried using Everest and MSI Afterburner for monitoring - GPU temps are not a problem as it seems. I've also used MSI Kombustor and I haven't been able to reach shutdown state neither, Furmark same result.
I've launched Lost Planet 2 then and let Everest do the logging, played until shutdown (cca 1 min after start of mission):
GPU1/2 load: 99%
MB temp: 40°C
CPU temp (4 cores average): 30°C
GPU1 temp: 58°C
GPU2 temp: 60°C
GPU1 VRM temp: 68°C
GPU2 VRM temp: 91°C (?!)
GPU1/2 VRM voltage: 1,18V
now a little strange thing probably:
GPU1 VRM current: 40,45 | 60,06 A
GPU2 VRM current: 52,71 | 38 A
those last two readings in my log before shutdown are separated by 5 seconds, why sudden drop of amperage?
Do you think it's my graphic card overheating? I mean, it's brand new, no OC done, I'd really like to know, how come it could be overheating? I have huge case Lian-Li PC80, 3 fans front, 1 exhaust top, 1 exhaust back, 1 exhaust on PSU, the card itself has 3 fans. And how come I had the exact same problems with dual HD4870X2s, where the powerful fan helped? (I can't try the fan now, because with my PSU replace I lost one of my "experimental" rails I got on the old one and cba to mod with this new one)
The PSU is also brand new, it was replaced along with card and imo should be sufficient, I have only 2 HDD + system SSD one.
