5770 temperatures

Would be interested to hear what sort of temperatures people are getting with their 5770 cards and cooling setups.

I'm using a Sapphire 5770 with stock cooler removed and replaced with Thermalright HR-03 Rev A.

Running a passively cooled Intel i7 860 2.8GHz with Scythe Orochi Rev.B heatsink. Etasis PSU is passive too.

All components are fine with this passive setup apart from the 5770, which gets a bit hot. At the moment I've put one silent fan in which is blowing in the direction of the HR-03, but idle temp of the 5770 is still about 55C and about 80C at high load.

Unfortunately due to sound cards my HR-03 is on the same side as the Orochi, basically touching each other, so I guess that doesnt help airflow for the HR-03.

Anyways, interested to hear what temps others are achieving.

Cheers,
Dutchie

Although safe, your load temps are on the higher side. A slightly higher speed fan attached to the HR-03 would give excellent results. With a 5750 & HR-03, was getting 40c idle and between 55-60 full load w/92mm medium speed Panaflo on the side panel (blowing on the card). Just guessing the 5770 would be 3-4c hotter or so in the same setup..

80 is a bit high. the idle is fine and dandy. I would bet a really slow moving fan perpendicular to the card blowing over it would drop temps like a stone.

I have a Sapphire 5770 with the rev2 (egg-shaped) cooler. With the fan locked on 20%, I idle at 37C and max at 75C.

your delta temp with HR-03 is quite good at ~25C. I actually have a hr-03 just sitting in box, haven't decided if voiding the warranty is worth it.

The stock 5850 and 5870 run at higher temperatures than that, so you're perfectly safe. As long as the VRM temperatures aren't going high enough that the gpu downclocks, there's no problem. If that happens during normal usage (not furmark/OCCT) you need to add more cooling somehow.

Perfectly safe with a shorter lifespan? Or perfectly safe with 3+ years of life?

there is no reason that a spcr modder can't get a gpu chip down to 60's C with a tiny bit of effort and in silence.

Of course the lifespan will be somewhat shorter than if you can run it cooler - that's just how electronics work. By the time the card dies however it will already have been obsoleted for several years. The built-in safety features and low power usage already means that the 5xxx generation should last longer than their previous GPUs. Unless you do something stupid, like run SETI@Home 24/7, the card will be running at low voltage and speeds the majority of the time, and only get hot while running games. While this was true for earlier GPUs, they didn't have the low power idle modes that these new ones do.

Thanks for the info guys. What temps do the stock 5850/5870 run at?

Running Furmark, mine goes to 85C.

If I tick the Xtreme Burning Mode on FurMark it shoots up to 95C, at which point I stopped the test!

Was hoping to be able to run totally passive, to optimise convectional cooling but guess that's out of the question.

Shame because the Scythe Orochi is doing a great job passively on the CPU.

Please don't do this to your card. it's making my blood curdle...

5850 stock cooler runs about 77c load and 40s idle.

I found its fine as long as you dont touch the heatsink - then your blood doesnt boil

my 5750 overclocked 20% reaches load temp of 65C, idle is around 35C. vapor-x cooler, if you're wondering.

furmark settings: all options selected, 1080P, 8x MSAA for 10 minutes:

another furmark test, here you can see the fan speed:
