Worried about 5770 crossfire temps

post #1 of 32
Thread Starter 
In my sig rig when I fold using the cards or game for 1h+ the temp of ONE of the cards gets to 88-92C. Is this a safe temp?

Leaving the cards folding on BOINC overnight at that temp means they run for 8 hours cotinuously at this temperature...

that isnt a very safe temperature at all.

you should be lower than 85c and preferably lower than 80c. are you overclocked?

also is one fan blocked by someting so that it cant get air?

While these cards are rated over 100C, you definitely want the temperatures to be as low as possible

A load temperature of 50-75 is ideal for an GPU, and different people will give their own opinions of an ideal temperature range.

You may want to start thinking about increasing the fan speed if you haven't already

It`s in crossfire, but they have a couple of inches between them. Nothing else in PCI/PCI-E slots. The fan speed is currently on auto but seems to ramp it up to 85%+ when it gets hot. I have NO overclock at all, currently stock speeds for both GPU.

I tried setting fan speed to 100% but it makes no difference to the max temp under load (gets to 87ish) and is VERY loud.

Maybe I'll just sell one/ sell both/trade them for a single 5850

Edit: Recently did cable management to increase air flow. Also removed the PCI sound card that was there to give more room between the two cards.

I used to have the same problem. You can fix this by either putting an antec spot cool aiming between the cards or by adding a side case fan blowing air into the space between the two cards. Brought one of my cards from the mid-high 80s to mid 70s.

ya im guessing the issue is your card position and airflow. an 80mm case fan would easily fix this by blowing fresh air through the heated air in between the video cards

Not a permanent solution, but try taking the side cover off.

Do you have a front-mounted fan blowing fresh air into the upper compartment? Are you using the upper HDD cage, or the lower one? Can you remove the upper cage assembly, so more air can get to the video cards?

Can you swap the two cards and see if the temperature problem follows the card, or is it related to the position of the card?

If airflow is not the problem, then try replacing the TIM on the hot card.

Or...buy a 5870, they rock. I would not recommend a reference design, as the VRMs will probably overheat.

BTW, if you like folding, is it worth getting a GTX465 and unlocking it to 470 status?

I'd like to but I don't have anywhere to install it (anywhere I can screw in to hold it stable). I'm hesitant to put a free-floating fan in my case, even if it would help temps a lot and I don't move my case often.

I don't have a place to screw in the fan there but it DOES fit. I was thinking of fixing up something but I'm really bad at that kind of stuff. The upper HD cage has room though. The side cover helped a bit but not that much. I have never replaced TIM as I'm afraid of voiding a warranty (have had GPUs die on me during warranty time)

I am considering getting a 5850 since I think it would suffice of an Nvidia equivalent since I DO like to fold...but right now I'm looking for a cheaper alternative lol

dude hotglue the fan to the side panel grill also 2x5770 > 5850 > 5870..so don't sell one off..
