Yeah, pretty sure that's actually the issue.
Hmmm, probably the reason I bought 3 BFG GTX285's a week ago :))) Semper ubi sub ubi. |

i know that when my BFG GTX 260 FOC 216 SP.. gets to 75C it shutdown the computers b/c of overheating... maybe a BFG safety feature or faulty sensor but i actually like that about my card, means that it's safe until about 70 C... |

Hi, I'm using a Palit GTX260 Sonic 216SP graphics card. Yeah I know, that is the one that is OC'ed by the manufacturer. I know everyone says they are b###sh#t and not even worth buying. I will NEVER OC anything in my computer myself. For a good lifetime of your computer, buy good equipment and UNDERclock it (or leave it on stock ratings). Funny thing #1: The Nvidia VTune utility they had on disk keeps my gpu at ca. 65 °C, while being at 40-45 % speed of the two fans. Funny thing #2: When manually setting the GPU's fan speed to 100%, I can cool down the GPU to 45°C under full GPUGRID load! On the downfall, it is loud as hell then. Funny thing #3: Playing AION (my I-really-love-it-MMORPG) which uses a modified CryEngine1 as graphics engine, my GPU yawns and goes to bed while still giving me 60+ fps... =Lupus= |

I have a palit GTX260 and managed to OC it quite well. I found the sweet spot and kept it there for a while, but I now just go native because the noise was just a little too high for me to work at the system. For those that keep their Fan at 100% - dont! It will drastically reduce the life expectancy of the fan, and could take out the GPU. |

It will drastically reduce the life expectancy of the fan, and could take out the GPU. .. but it helps the GPU and the rest of the card ;) I will NEVER OC anything in my computer myself. For a good lifetime of your computer, buy good equipment and UNDERclock it (or leave it on stock ratings). OCed or underclocked doesn't mean much if you leave the fan on auto. OC'ed (stock voltage) 70°C will be much better for the card than underclocked 90°C (stock voltage). MrS Scanning for our furry friends since Jan 2002 |

i run stock settings for my FOC 216 260 from BFG... 70% fan with window closed = 63 C 70% fan with window open = 55 C. |

You are quite right to say that it reduces the heat and increase the life expectancy of the cards other parts. Right up to the time when the fan fails, then it is a bit hit and miss how things turn out. If you have a GPU sitting at 60degrees, the fan fails and the card shuts down; because it detects a fan failure or even after waiting to the card heats up to 85degrees (or whatever the cut-off point is), all well and good; Your system might not stay booted too long, but at least you will be able to work out why and twiddle your thumbs for a few days when you wait for the replacement fan, or RTM replacement. But, if your OC'd card is sitting at 79degrees and there is no automatic shutdown, you are in hot trouble. This is the reason that house insurance companies put clauses in about modified electronic equipment, and why I only use metal system cases. If you don’t already have them, good system fans will help. Might let you get away with a modestly raised (40-80%) graphics fan speed. Sometimes they can even make the noise bearable, when the window is open! I feel a similar effect when I open the window. The room temp drops to comfortable, but in another month it will be well below comfortable. Last summer I sometimes sat a fan on the open windows frame to suck in the slightly cooler air. I went PC-green; hooked up a USB fan to a Solio. |
