Hi guys!

I bought a 280GTX recently. I always knew it would run hot, but Furmark 1.8.2 shows it running at 105C. If I game for more than say 30 minutes the computer shuts down and refuses to reboot immediately (presumably because the GPU is so hot). Am I correct in saying 105C is the cut off point where it'll go into safe mode?

In the Guru3d article it states

"In idle you can expect a temperature of 50-55 Degrees C. Pretty normal. Yet once we push the GPU to 100%, the temperatures take a pretty hefty toll and settle at 85 Degrees C, that's 185 degrees F. And that's just really a lot, something I dislike as that's 20 Degrees C away from the 105 C threshold of the GPU jumping into SAFE mode."

I have what I thought was pretty good cooling in my rig, with a 12cm side fan that pushes air directly onto the GPU, a 12cm top fan that extracts air, and a 12cm back fan that pushes air in (admittedly through the mesh of a Corsair H50 radiator).

In any case, the temps go up to 105 in under 2 minutes, so ambient case temperature doesn't have that much time to affect the GPU itself. I also have an NZXT fan controller which speeds the fans right up when it detects a rise in temp (usually to about 40C)

Clearly the GPU is overheating, its a second hand card, do you think it is faulty or maybe is clogged with dust or something!

Any suggestions about a solution?

Turn up the air conditioning for the room? ^_^ It's brutally hot in Jersey here. (100F+)

Those temps sound a lot like what I had when I had forgotten to remove the aluminum bracket covering the second slot of the card here the heat is fanned out. In my defense, it was my first time installing a dual slot card.

Make sure the fan is spinning and that the heat exhaust isn't blocked.

Is your Power supply good enough quality to power the card ? excessive AC ripple can cuase tempatures to sky rocket.

I would clean it like other have said.

If the cooler doesn't look dirty, maybe consider replacing the TIM.

The original GTX280 batch had defective samples and this was a known problem (i.e. cards hitting 105c within minutes of entering a game). It sounds like you got one of those faulty ones.

i've seen so many instances where people have horrible temps not because a defect in the card, but simply because there are dust bunnies in there. first try blowing out the dust, if that doesn't work, open up the card to clean the dust. if that still doesn't work, then redo the TIM. nvidia always put a goop of 10x more TIM that you actually need.

The reason I asked this question is because I had a feeling I had read something about this.

Well, the card is pretty useless as it is at the moment, so I may as well try my best to clean it out and replace the thermal paste.

Oh, does anyone know of any good guides to cleaning out/taking apart a 280GTX?

Here ya go:

This one is just re-TIMing (new verb?) a GTX280. You won't have the back plate, most likely but the procedure is the same. Take note of the amount of TIM and cross pattern used on the IHS.

http://www.overclock.net/nvidia/759978-quick-guide-re-applying-tim-gtx280.html

This one is a youtube vid of a guy called Trubitar fitting a water block to a GTX 280. Ok ignore the waterblock fitting bit but seeing someone take the card apart carefully is really really useful.

HTH and good luck.

Thanks mate!

I'll let you all know how it goes (probably horrifically wrong, anyone need a expensive paperweight?)

Yup, my first two were defective, & 105C is indeed the magical point where they start throttling (fps will chug/stutter; especially obvious to see in RTHDRIBL).

You can certainly try redoing the TIM, but i doubt this will do anything as all signs point toward defective GTX 280.

Just to update you all

Though it was a second hand card, it had never actually been registered for warranty, so I filled in the forms on the manufactures website, and they agreed to RMA it. I explained to them the issues I was having and the symptoms the card was displaying, and they sent me an RMA form straight away, so I’d guess that that it was indeed the ‘known issue’ rearing its ugly head again. Anyway, the cards been sent today, so I’ll let you know the end result in case anyone else has this problem.

Hope you’re all well.

You got lucky with that company & filing quickly. BFG had top notch support, sadly they're leaving the market thanks to Nvidia.

You should still be able to get Warranty on your card:

BFG Technologies today announced their exit from the graphics card category. The company will continue to sell their line of BFG Tech power supplies as well as their Deimos gaming notebooks and Phobos gaming systems.
"After eight years of providing innovative, high-quality graphics cards to the market, we regret to say that this category is no longer profitable for us, although we will continue to evaluate it going forward", said John Slevin, chairman of BFG Technologies. "We will continue to provide our award-winning power supplies and gaming systems, and are working on a few new products as well. I’d like to stress that we will continue to provide RMA support for our current graphics card warranty holders, as well as for all of our other products such as power supplies, PCs and notebooks."
BFG will continue to offer RMA, telephone and email support for qualified BFG Tech graphics card warranty holders, but will no longer be bringing new graphics card products to market.

Can you believe it!

I just received the replacement card back - it has EXACTLY THE SAME PROBLEM!

ARGH!

It looks as though they have just stuck a new cooler on the card (since it was totally dust free) - when its the chipset that appears to be faulty!

I have emailed them again. We'll see what happens!
