105 degrees on my fanless gigabyte x800, what to do?

Under load im hitting 105 degrees or more on my fanless gigabyte x800.

Is this safe?

What can I do to reduce the temperature without voiding the warranty?

Cheers.

No.

Nothing

The stock heatsink is so bad that even putting a high airflow fan next to it isn't enough. Check this thread: http://forums.silentpcreview.com/viewtopic.php?t=19067. I've posted some pictures and results there, which might interest you.

Get an Arctic Cooling Silencer (my ATI 5 Rev. 2 is very good. Pretty quiet at 11% (arround 32C when room temps are arround 15C).

I think modern Radeons can run safely up to 125'C, but I'm not 100% sure so ask Gigabyte or ATI.
Just watch the northbridge if it's located close to the video card, it usually overheats around 65'C.

If you really don't want to void your warranty I think you may as well try putting a fan near the video card. Without knowing exactly how good the airflow is in your case, your situation might be different from other people's.

One idea I had for cooling such a card was to place a fan at the end of the card so that it blows over the top and bottom. Then open up a PCI slot both below and above (if you have an empty one - depends on motherboard design) to try and exhaust it out. Maybe some cardboard ducting around it to guide the air out.

is this the northbridge? (circled in red)

my video card half covers this.

how do i check the northbridge temp?

yeah that is exactly what you want to do. I would go 80mm panaflo on half speed at idle and full speed on gaming.

92mm zalman is ok, not the silent though compared to other solutions. I used it with its little swingarm for my older 9800 aiw pro.

x800 XL uses less power than the 9800, and the XT uses the same amount.

Yes, that is the northbridge chip (I assume that's your motherboard?). You usually can't mistake it since it's usually the only square thing on the motherboard that size with a heatsink or fan attached to it.

I believe monitoring programs like Speedfan and Motherboard Monitor will read its temperatures. I heard that more than 65 C is okay for northbridges, which routinely get really hot, but better check it if you're worried.

A Graphics card is totally capable of 105C. They are safe upto roughly 120C

I'd have a look at the thermaltake schooner. I've got one and it cools almost as well as my arctic cooler and gives me a better overclock too!

I have a TT schooner in a P180 setup, with a passive Ninja just above it. The card is a Leadtek 6600GT.

With only one nexus fan at the back, running at 5.5V, top hole unblocked i get load temperatures of 85C.
Same setup but with top hole unblocked, i get load temperatures of about 70C.
With 2 nexus fans at 5.5V, one top and one at the back, i get load temperatures of around 65C.

Idle seem to always be around 43-50C.

That is even better than with my stock leadtek fanned heatsink!

Does your card include a stock sensor? What safe temp can a gpu reach?

Thanks, I tryed that with an old 80mm fan and it took the load temps from 105-110 down to 75-80, so should be much more safe now.
