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.
http://minidriven.com/GreenMachine/S...5770tuning.jpg
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:

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:

Got mine a couple of days ago, and was pleased to notice I could put my HR-03 on it as well. Real nice GPU, and a vast improvement over my 8600GTs, and the cooler is quieter during idle than I expected, but that wont be an issue once I get the thermalright on there :)
Also chuffed to have spanned monitor modes back too. Just waiting for our Samsung 32" 7020 TV and Blu-Ray drive to arrive today, then I'll be a happy bunny :D
That's surprising. Is that testing the cards individually or in crossfire (I beleieve it's not unusual for crossfired cards to show different temps)?Quote:

I guess the picture will become clearer as time goes on and more people post their experiences with these cards, it's still early days.
Crossfire, with in both PCIE positions (MSI in slot one, then Sapphire in slot one) and separately.Quote:

the gpu usage is a bit off, 93 vs 99% but that doesn't translate into 19C. That's something that I'll have to look into. Could be a driver issue.

Do you get the same temps if you don't use the two cards at the same time?
The MSI card is actually cooler.
thanks rev, glad I bought the v1 coolers :) on all 4 of the cards I have comming
you have 4 on the way? Get your hearing protection sorted before delivery....they're loud lol.
Thanks ReverendMaynard.
Are the sapphire and asus coolers the same, they don't look like it to me.
Identical reference design for all V2 5770's. It's just the angle.
yeah top secret mission ;) Just testing 4-way out on the new board and antec tpq-1200 :up: def need muffsQuote:

Must say I'm very surprised by that result.
We need more people with both revisions to really get the gist, but being someone who's been in the industry for years, unless something is failed outright, which the REV1 cooler is not by any means, companies won't just gift out a better cooling solution...they find the cheapest regardless of the performance.
you all made me worry a bit cause i bought a v1 5770 cause i needed a gpu fastly since it was my only parts missing for my build ( damm 5850 that was always out of stock made me go for the 5770 and i am very happy with it). About temperature, when i was running 3dmark vantage, the highest temperature i have seen was 52c and the idle temp is 30c with user defined fan speed in msi afterburner. Was running 960/1440 at 1174 volt with xfx stock bios, now its running at 1174 volt, 950/1350 when i need some extra power in game. In s4 league with 1920x1080 with high detail, it never goes up more than 44c
your temps are pretty much exactly how the V1 should perform.
It's more unusual for a company representative to make such a claim that's so easily disproved, though. I mean, to state an improvement had been made when actually the opposite is true would be a pretty stupid thing to do, wouldn't it?Quote:

It's not the design from the 5750. If you look closely at a 5750 the heatsink is very different underneath the cover - no heatpipes, just a very regular finned heatsink.Quote:

Yea, they do look similar from a glance. I don't own one either but when the new 5770 V2 appeared, my first thought also was that they'd switched to the 5750 cooler so I checked out a few pictures online.Quote:

Im not sure whats up with my cards. You can see the whole thread I made on how hot they were getting with the V1 cooler, the first card was hitting up to 100 degrees when clocked to 1 Ghz with default fan speed.
I dont actually trust the results shown in this thread after having already tested mine, there is no way that the V1 cooler can keep the card below 50 degrees under full load.
http://www.xtremesystems.org/forums/...d.php?t=238123
Not looking for any trust to be honest, just trying to let people know that V1's aren't as bad as people like yourself have made them out too be. I can't force either of these cards to hit 100C without failure so too me, your results cannot be trusted.Quote:
Originally Posted by bhavv

When clocked to 1000 Mhz on DEFAULT fan speed, the V1 cooler would cause the chip to exceed 100 degrees under both battleforge and Dragon Age Origins.
When the fan speed was raised to 75%, the temperature dropped to around 88-95 degrees but while making much noise.
With the Zalman silent heatpipe coolers, my cards are now down to around 80 degrees at 1000 Mhz.
You will find that if you repeat these actual gaming tests on any V1 cooler at 1000 Mhz, you will get the same results, furmark temperatures are around 10-15 degrees lower than actual gaming results are.
The tests shown above were also done open case, hence not an accurate reflection of the temperatures you would see under normal use.
Also, I think that the V2 cooler may actually have a lower RPM as it is described as a quieter cooler, so even if both are at 50%, the V1 would be spinning faster, which would make it a biased comparison.
The earlier comparison screenshots show one of them at 1 RPM, so there is a problem there and the comparison may not be at the same RPM.
I am also only bothered with temperature readings at 1000 Mhz because the V1 cooler is fine up to 960, it only starts failing with an unlocked bios.
Under the assumption that the V2 cooler performs the same as my Zalmans, then that is what makes me believe it is better while being completely silent. I personally could not tolerate the sound level of two V1 coolers at 75%, and I have severe hearing loss too.
Download battleforge for free which uses DX11 and test your temperatures while running that game, and I am sure you will see 90-100 degrees :).
No game will put near as much stress on a gpu as furmark does...
The only conclusion would be that your Coolers were'nt making full contact with the gpu, there's been a couple of cases that proved this.
or you live in a country with 65'C ambient...
Here is a screenshot of my xfx with the stock cooler on 70% fanspeed...
http://i37.tinypic.com/4uvuc3.jpg
^ Almost identical too what I get, except my memory dumps at 1430. That's a decent card keenan, is the memory stock volts?
V1 didn't perform very well for me either.Quote:

In Xfire the temps can get out of control quick. 1 GPU will normally get hotter than the other unless a great cooling solution is being used.
Yep, no hardmods, just pulled the slider to the far right and there it stayed ;)Quote:

Thanks for the results ReverendMaynard, looks like I will be getting another 5770 with the V1 cooler instead :)
Heaven benchmark puts more stress on my GPUs then Furmark does. The difference isnt the cards being at 100% load, but when all of the GPUs features are utilised as in DX11, then the temperatures will go far higher than the maximum they get under furmark.Quote:

I had my cards 100% stable in furmark at 1025 - 1050 Mhz, but as soon as I loaded up Heaven benchmark or a game, they would crash within a couple of minutes. Furmark is a very unreliable stress test for these cards.
This right here was the usual result for my overclocked cards under Battleforge with the V1 cooler:
http://img406.imageshack.us/img406/2203/57701ghz.png
With the stock V1 fan on default, it would spin up to around 66% at 100 degrees, I were getting around 105 degrees without manually increasing the fan speds myself.
As a comparison, this is 1000 Mhz under furmark with a 75% fan speed:
http://img99.imageshack.us/img99/9553/5770stock75.png
The difference may be because I couldnt get both cards up to 100% load in furmark.
P.S. Reverend, you could maybe try leaving your cards stressing for a lot longer then you did before untill they reach their maximum temperature. Temperatures from just a few seconds into Furmark arent exactly showing the cards fully heated up.
I mean how can you argue this? he has both the v1 and the v2 and the v2 isnt even close? Mystery solved.
can't please them all Bobby.
Last night I was running the RE5 bench at 1650x1080 at 1000/1350 1.3v (DMM'd). The bench finished fine but when I got back to the desktop to check the temps, small pixel/shader type artifacts started to appear and then the system froze. I pulled the V2 card, re-ran the bench at 1041/1401 with the MSI V1 card and it had no issues, with the high temp recorded at 60C bang on.
Each one was only tested for a few seconds at stock speeds, not at 1000 Mhz or for long enough to allow the cards to reach maximum temp.Quote:

I already know that the V1 cooler hardly goes over 60 degrees at stock speed and settings, that is not what I am bothered about - overclocked temperatures at 1000 Mhz is.
Your sig says that your cards are clocked to 1000 / 1400 right? Mind posting the temperatures you get at those speeds with furmark having been ran for at least 10 minutes?
The small pixel / shader artifacts are caused by the card dropping back into 2D clocks, this is a very common problem on the 5770s and has nothing to do with overclocks or temperatures.Quote:
Originally Posted by ReverendMaynard

Like I said, post a 10 minute furmark run showing your temperatures as your claims are very very far off what other people have been reporting so far. But if you pulled out the second card, then yes your temperatures would drop by quite a lot when running just a single card. Crossfire temperatures are a lot higher then single card temperatures would be.
I am actually more interested in seeing two V1 cards, and two V2 cards in crossfire compared at 1000 Mhz, as this is what stresses the cards temperatures the most. Single 5770s do manage to remain below 70 degrees on the V1 cooler, but when two are put together with each one running at 100% GPU usage, this is when the temperatures go far too high, which was exactly my problem when running two V1 cooled cards.Quote:

Of course, with everyone here posting completely different results - single card / crossfire cards, stock speeds / overclocked speeds, no conclusion can actually be drawn as to which cooler is better, but I can at least conclude from my results that two V1 coolers are not capable for keeping temperatures acceptable in an overclocked crossfire setup, but the heatpipe based Zalman VF950s definately are a lot better.
Go buy a V2 5770 and test it yourself pro. The day hwbot starts giving boints for furmark, I'll invest more than a minute or two with it. Otherwise, it's a card killer everyone knows that.
Keenan posted the results you're after. Seems like you're just pissed that your V1 experience isn't normal.
I'll see if we received 5770 tonight at work, I could bring a pair here to test on my new rig during the weekend.
Keenan is on water cooling, my issue was V1 cooler vs V2 at 1000 Mhz. I really dont have the money to go buying another two cards.Quote:

You are very capable of testing that, but for some reason you choose not to, I dont know why.
My V1 experience is completely normal, and is the same as what other people are reporting. You will get the same results in crossfire as well with both your cards at 1000 Mhz, but you are not posting anything to confirm how good or bad they are at 1000 Mhz.
At 850 Mhz, both my V1 coolers kept the cards at around 60 degrees, this is a normal result, but you still have not disproven that the V2 cooler may be more effective when the cards are clocked to 1000 Mhz.
I have already fully tested V1 vs Zalman VF950 - which is very similar to the V2 cooler. The heatpipe based coolers are far better when the card is overclocked, while also remaining silent.
I am sure that Asus's claim that the V2 cooler is quieter while offering lower temperatures is 100% true if the two were properly stressed.

Yes, but that is a single card with the fan at 70%, which is loud.
And crossfired ones run a lot lot hotter then a single one does.
The V2 would be able to offer the same performance in a single card setup while remaining quieter, plus performing better at higher temperature.
The V1 cooler is completely fine and has no problems up to 960 Mhz on these cards. But when you go above that, they need to be set very loud to keep the cards adequately cooled, particularly in crosfire, whereas the V2 will do the same thing while remaining much quieter :)
Are you sure the sapphire one has the two large heatpipes, I have not seen proof of them in any pictures.
yes it has the heatpipes, it's the exact same cooler as ALL of the V2 5770.
http://www.xtremesystems.org/forums/...9&postcount=29
Look at the pic and you'd see the heat pipe.
I confirm that Sapphire has switched it's SKU for the V2 cooler, we received one today and it's got the egg lookalike cooler. I'll bring one home to do some testing.
As you can see below, the V1 cooler of my asus & gigabyte are doing a good job!

Even @60%, it performs well:

This thread is funny. Why no one has mentioned that AMD calls Furmark a 'power virus' and seems to actively throttle cards in some way (probably through drivers) when running it I'm not sure. So Furmark is not the way to stress these cards.
That's a bold statement.Quote:

Furmark on Radeons 4870 made them hit 85C easily. This is probably just fudd.
I tested the Sapphire V2 5770, the cooler seemed to be adequately quiet for stock operation, didn't bother OC it tho. Without any tweaks, the cooler remained relatively quiet on a open bench, thought the fan will spin faster during stress, just not too much, couldn't monitor the speed of the fan as I didn't want to install CCC. I did notice something strange, the clock speeds reported by GPU-Z were flickering all along.
I saw that they removed a few capacitors on the cards, althought it uses the same PCB, there are 2-3 capacitors missing for sure.

UHmm to bad. It looks like they made a cost reduction on the 5770. I cant get any V1 in my country. But there are a lot of shops with the V2 :( to bad i would rather have a V1.
I have the Asus 5770 V2 ("egg" cooler) and I'm very pleased with it.
Haven't played with it much but it's running 1GHz/1250MHz at 1.225v and after a 10 minute soak in Furmark it reached 66C with the fan on auto and the temps appeared to have levelled off. In games it hasn't got hotter than 51C and it idles at 29C. So far I haven't noticed any noise from the fan, it's doing a great job.
It gets the thumbs-up from me. :up:

I'd be interested to see comparable V1 test results, run for a similar length of time etc to get some idea what's really going on with these coolers.
Ok, here are my results after 5 minutes of Furmark on a V2 5770 overclocked to 1003MHz/1250MHz, 1.225v.
Relevant info:
Ambient room temp = 19C. Card cooling is totally standard, straight out of the box - no lapping etc and the TIM is original. Running at 1003MHz/1250MHz 1.225v inside a tower case with side panel removed, no additional fans cooling the card. Card fan is set to "auto" and doesn't exceed 65% during the test (as can be seen in the screenshot). Furmark settings can be seen in the screenshot.

Also since both cards have different PCBs the best way to see which cooler works better will be to put the V1 and V2 heat sink on 1 card only.
The new PCB may effect the overall heat of the card. So it would be best to test the heat sinks on the exact same card with the same conditions.
The V2 heat sink looks superior.
I got two MSI's recently and got the V1 coolers, honestly, they look way sexier (What's up with all this egg crap?) and i prefer them because hot air goes out the back of the case and not into the case ;)
Crappy pictures of the card online finally.

I have 4 of these and im pissed. They run cool enough for my purposes at 100% fan speed. But they use cheap as ram that wont go past 1350Quote:

has any one tried Arctic Cooling L2 Pro ???
I have one (AC L2) on my old X1900XT that I put in the HTPC. It's a good cooler, but his only made of aluminum, so there are limits to it's effectiveness.
So go for V1 if possible?
100% fan speed seems excessive to me. I'm happy with the overclocked temperature of my card at only 65% fan speed. I've yet to see a comparable test showing a V1 card doing any better, but I have read about many doing quite a bit worse on the various hardware forums. ;)Quote:

My sapphire V1 cooler gets the job done @65%:

Nice one, seems to be working well.
