HD5770 Cooling

[SilverSilence]

How do i increase the 2D clocks of the 5770?

@pvhk

Arn't the fans insanely loud at 75%?

[pvhk]

probably for someone who is in search of silence!
For me: no! What matters for me is that this heatsink does a great job when it comes to oc!
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.

I'd like to see a quote of that directly from AMD if you can provide. I've run furmark on dozens of AMD/ATi cards and never witnessed throttling in either the benchmarks or the extreme gpu burn.

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.

That probably saved a few bucks.



So I guess it's safe to think that the V2 HD5770s are all about saving money in production costs.

So strange that the HD5770 was changed so fast.

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.

I tried to say this a few pages ago and no one believed me lol.

That's for a couple of reasons: Your testing methodology (as explained to you at great length by another poster) and because you also said they down-graded the cooler to the part fitted to the 5750 cards, which was incorrect.

At the end of the day, it's only a graphics card - V1 or V2, does it really matter? As long as people are happy with their purchase, who cares?

When someone asks me to burn up a card for the sake of proving something I already know...I'll do what I think is best for my gear, not for the better of the 5770 club even if they are cheap cards. RMA's cost time.

And so I made a bad on the 5750 cooler comment. Give me an effing break guy lol.

That's part of the problem - you had already formed an opinion in your own mind and this shows in your testing.

[ReverendMaynard]

Common sense prevails. Give it a shot, it saves allot of unnecessary time and effort.

[Touche Turtle]

Firstly, I don't give a monkeys which is cooler, as long as they each do a good enough job, so this isn't a desperate attempt to try and prove the V2 is superior - I'm simply trying to form an impartial opinion based on reliable and unbiased testing. 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.



GPU temp: min 30, max 65
GPU usage: min 0, max 96
Fan speed: min 50, max 65
Core clock: min 157, max 1003
Memory clock: min 300, max 1250

I still think more test need to be done to show which cooler is better.

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.

[SilverSilence]

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

[kiwik]

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 1350

[pr@$r1g]

has any one tried Arctic Cooling L2 Pro ???

[kiwik]

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.

[nullface]

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.

Where did you source the RAM price? I wouldn't have thought it was "cheap as" - they're the exact same modules as fitted to the 58xx cards.

[pvhk]

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

[Touche Turtle]

Nice one, seems to be working well.
