Cool. I saw a few threads here and there but not a specific thread where everyone could share there set up.Quote:

^^ yeah & i have put some MX-3 to cool it down
The new batches of the 5770 are now being sold with the Egg heatpipe cooler:

The cooler on them is mighty big, doesnt look as nice as the phoenix shroud, but the heatsink is like 3-4 times larger. I knew I should have waited, I wouldnt have needed to buy the Zalmans then :(
Here's another thread about the new 5770 V2 (with a reply from someone from Asus).

Hey,
Yes, we've changed the cooler on the cards. You'll find that the new cooler is quieter and provides better temperatures.
You were right about the model code too, the "V2" describes that change of the card and is going to be replacing the original card (In the UK at least).
Here is some initial results on cooling with TR HR-03 (rev. A) heat sink. no fan on single HD5770.

My Antec 900 case does have a side fan blowing air onto the heat sink.
If anyone knows of a good 92mmx92mm25mm fan with 4 pin pwm connection for HD5770 please direct me to it. With a fan I think I can lower my temps even more.
yeap stock cooling with costum fanspeed setup in afterburner.Quote:

I also noticed that the same voltage from 850core to 1000core
1)1000core is stable exactly 1,340v +-0.002 while 850core goes 1,330+-0,01!!!So clock high to get stable voltage!!!
2)850 core needed 1,330 while when set to 1000 it get to 1,34!
you seem to use high voltages...Quote:

Really? I can only see that happening if case ventilation is poor.Quote:

With good case ventilation the V2 cooler should perform better with its thick copper base, fairly big heat-pipes and top-down fan.
The RAM chips on the front of the V2 card aren't 'sinked like they are on the V1 (they are very low-profile 'sinks, not really up to much), but they are unobstructed by shroud/platic and are directly underneath the heatsink so will get a constant direct flow of air from the fan. There looks like there's enough room for decent ramsinks too.
I didnt know that... have link to this info:yepp:Quote:

Exhausting hot air is pointless when the tiny heatsink cant even keep overclocked load temps below 90 degrees.
Heatpipe fansinks have always been better at reducing GPU temperature, and why on earth does case temperature matter at all so long as your GPU and CPU are adequately cooled?

I have 2 HD5770s. I have been running a single HD5770 with the TR HR-03 (rev. A) for over a week now. Just seeing how it runs with the TR HR-03 (rev. A) without a fan. Seems to work very well and I'll put the other HD5770 with same heat sink together soon.
I agree with all you said except the last bit which I've highlighted. Case temp is critical to how well an air cooler works - no heatsink in the world can cool below the ambient case temp. If the case temp is hot then so will the cpu & gpu if their coolers are using the hot air inside the case.Quote:

As long as you have an intake and an exhaust fan, you have cool air ;).
Most cases these days have two of each.
Yup, as long as case ventilation is adequate there shouldn't be a problem. It just that your previous statement gave the impression that case temperature was irrelevant, which is totally wrong:Quote:

Personnally, i'm happy with the stock cooler V1:
my CF runs @1010/1250 @1.237v max gpu temp@60°
my single sapphire @1070/1350 @1.274v : max gpu temp@68° (this card runs hotter even @stock compared to the others but hits higher clock: 1100mhz for the core!)
I'm not disturbed by the noise of the fan even @80%...
really, and my system is on a tech bench in a 20C ambient environment. My MSI V1 5770 idles/loads at 27C/60C and the Sapphire V2 idles at 40C/70C. Both retimmed with MX3 and both getting enough air to rule out ventilation. The V1 cooler might be basic, but the design is better by miles just because how the air moves across the sink.Quote:
