I bought my box about 2 weeks ago at Newegg. The graphic card is a HIS 6870 and the PSU is a Xigmatek 400W.
The card requires juice from two 6-pin connector. Since the PSU only has one 6-pin power connector so I was forced to use the power converter to connect two 4-pin to fully power up the graphic card.
It has been working great for the last week and a half. Yesterday I was having some problem while playing Fallout 3 (with the high res texture mod) where my computer would freeze and reboot. At first I thought it was a software / fallout related problem. After having no success at fixing it, I fired up the Unigine Heaven Benchmark and to my surprise the computer crashes and reboot after a few minutes.
Later on I found out that the card is running at around 50+C at idle and can go over to 80+C, keep rising during load before it finally crashes. This is in contrast to anandtech's measure of the 6870 temperature (40 at idle, 72 at load). All this time, the GPU fan does not seem to budge all that much and stays at 30+% fan speed.
Check my box again, cleaned up all the dust (hardly any), checked the cable and connector, checked if anything is interfering with the fan. I am running out of idea at the moment and thinking about setting my fan speed manually using Catalyst.
Advice please ?
