Good morning ,
I just got a new Nnvida 6800 GT last week. I had to putin a new power supply 500 watts due to over heating. I am still crashing. I have my computer open and the temp for the GPU is in between 62 and 65c . Any solution to the problem.
Pentium 4 CPU 2.6GHz
WINDOW XP PRO
GEFORCE 6800 GT AGP 8X 256
1GIG MEMORY
80GIG AND 40GIG HARD DRIVE

From: someone There's no problem there, thats NORMAL for the 6x00GT GPUs. If you wanna cool it down you'll need a better cooling setup. An exaust fan below the GT and if you're willing to get your hands dirty, an all copper heatsink/fan replacement kit to cool that bad boy down some more. That should shave off a few degrees, ultimately a liquid/phasing cooling system would be more ideal to ice it over (along with your CPU and Chipset) but that can get exspensive unless you like fabricating.
Also some ideas to help improve airflow in your case:
1) more fans, if your case can support them install them.
2) replace your ribbon IDE cables (hard drive, cd-rom, and floppy cables) with round cables.
3) tie your power cables together and out of the way with twisty/zip ties.
4) take a can of compressed air and clean out the dust buildup in your case every so often.
All of this will increase airflow in your case and better airflow will allow for better cooling. Hope this helps.
EDIT: Also if your chipset uses just a heatsink with no fan it might be helpful to replace that with a VGA fan, all copper prefered like the Thermaltake Crystal Orb. Yes I know its for a VGA chipset, but the motherboard chipset is roughly the same size and uses the same mounting points. Be sure to use Artic Silver 5 compound for best results when swapping the heatsink and fan (GPU, CPU, or chipset).  |

I was looking at the cooling system. wouldnt be cheaper for me just to keep the CPU open and have a small fan. The once I looked aat small box that sits outside the CPU.

That is indeed a cheap solution and perfectly suitable but not terribly elegant. Having the case open leaves you open to having things fall into it and increases the noise. A fan blowing into an open case really isn't a permanent solution but it will certainly work. As far as round cables are concerned, I'm not convinced even though I have them in my computer. A simple matter of folding them out of the way and with the direction of airflow is more effective and significantly cheaper. Placing a PCI slot fan next to the card will help a great deal. Also, it may be that you are getting a false temperature report. (I think this is a known issue with some 6800 cards) One way to check would be to open the case and first grounding youself by touching a piece on metal on the case and then touch the heatsink of the video card. 65 degrees C (149F) would be hot enough to burn you, 35 is warm bathwater (95F). My 6800 Ultra runs around 35C at idle, 50C when SL is running. Make sure your motherboard, Directx, bios and video drivers are up to date.

80GIG AND 40GIG HARD DRIVE what was overheating before? as has been said, that's a perfectly fine temp for 6800GTs. It may not be an overheating problem at all. It could be a faulty video card, it could be dirty power, it could be bad ram, it could be windows. |

I upgrade from Nnvida G Force 5700 LE AGP there was nothing wrong with the card. just wanted to upgrade. When I put the new card in notice I would start to free then crash after about 6 or 7hrs on sl. How can I tell its bad ram or the power is dirty or if the video card is faulty?

From: Rickard Roentgen What happens when it crashes? I would freeze for about 2 second or the other night I froze where I got a blue screen. Saying it was from the nvida and it had to dump memory. I had to shut down and reboot. What temp should computer be at.

Check your other fans too, these high rpm high volume fans have a tendency to lay down a dust carpet right between them and the heatsinks effectively shutting off airflow See if you have a chipset fan on the mainboard ... these really small buggers burn out in a week, I usually remove them becuase .... Most cases have a 60 or 80mm fan bay(s) next to the cpu,chipset, and the back of the video card. (if you think about it the heatsink is on the wrong side of the video card in a tower) If you can add one and set it where it blows out the back. the idea is to suck cool fresh air from the bottom (usually from the front) and blow hot air out the top. Heat rises so therefore if you blow air in the top all it does is move hot air around the computer. Get some twine or zip ties, and tidy up wires, keeping the most amout of free open space from the front bottom to the back top for airflow. The last "rats nest" I dealt with, 1 fan and wire-management reduced the internal ambient temp by 23c. Ok I could go on for days about this, computer cooling is a hobby of mine  |

and to me if the card is good it sounds like the mainboard chipset overheating
