HD5770 Cooling

[ReverendMaynard]

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.

He has 4 cards, and he's tested them thoroughly so what it looks like here is you're just looking to disagree because you can't bring anything relevant too the subject other than you've seen different or better results on other forums. Seriously go somewhere else if all you can do is be a pita.

FYI, his "cheap" comment was based on the FACT that the V2 was introduced to cut costs.

No need for a hissy fit - you've got me all wrong. Re-read my posts and you may understand where I'm coming from. I'm trying to show some decent test results here, not half-baked 15 second test runs like the one you based your conclusions on.

Don't want to take the wind out of your sails but I've been a member here for years and it'll take a higher authority than you to get rid of me. If a mod tells me I'm overstepping the mark then I'll gladly wind my neck in but I think you're over-reacting.

[ReverendMaynard]

If you're going to insult test methods at least know wtf you're talking about and please don't exaggerate. The test I showed was 61 seconds, 1 hour doesn't produce higher temps....at all. So please stop with the bs and bring your own tests to the table.

You can give us all 30 minutes furmark on your stock cooled V2 @ 1000/1400 at whatever voltage it requires or stfu please

You expect me to believe those temps were maxed? Look at the picture you posted again, look at the temp graphs. Do they look maxed-out to you? No. They are still very much on the rise and no-where near levelled-off.

I don't know what you're trying to pull with this bull- fella, but please credit us with some intelligence.

Hmmm, why are you asking me to "bring my own tests to the table" when I already have?!! (Look on the previous page fella, it's there, clear as day for all to see. Nice solid methodology too ).

Edit: here is the picture I was referrign to, posted by Rev. So, you're telling us after just 1 minute of Furmark, these temps have reached their peak and have levelled-off, despite the fact they are clearly still ramping up as can be seen in the picture?

[MadMan007]

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.

Not sure this is worth it given your less than friendly replies otherwise but..it's not very bold, AMD called it a 'power virus' themselves and have been throttling cards through drivers it turns out for a while, or maybe they've gotten a bit more sneaky in the throttling so it doesn't show up in simple frequency graphs It may just not happen all the time or only on higher-end cards too Google 'furmark power virus' or 'AMD power virus' and do some reading.

True but the new 1.7 furmark has a renamed EXE. So the driver will think its a game. Or they have to have some other kind of protection against it.

Furmark does load higher then games. But because of that its a good test for your cooling setup an stability. And there are soms GPGPU apps that come close to the same kind of load that furmark gives.

[MadMan007]

Renamed .exe doesn't fix it (from Furmark's viewpoint) AMD changed that in their drivers long ago and now they apparently do some kind of check for the actual OpenGL calls that Furmark runs. If AMD wants to throttle it or keep it from overloading their cards they'll find a way, the occasionally updated Furmark isn't going to keep up with them. Whatever...Furmark is just one program after all and we shouldn't be so umm...religious about it.

Here's the first review I've seen which directly compares the V1 and V2 cards. I've no idea how reputable the review site is but it seems sensible enough, if a little badly translated.

Full review here.

Here are some quick snaps I took of my 5770 with the thermalright HR-03 on the card which I decided to run with a 120mm fan on about 600rpm just to keep a bit of a flow through it...



And the results:


As a result, the heatsink didn't really allow me to push much more out of the core, and the memory o/c improved a little, but if this card is going any further, I think it'll need some more volts. It obliterates my 8600GTs, and with me not being much of a gamer, it'll be all I need for a while (although I hear these cards x-fire really well). Idle temps are as low as 35°C in a closed case which is quite a big improvement (used to be ~45°C). Load temps decreased by about 6-7°C.

The one thing that got my attention was the small component underneath a part of the long ramsink section which was covered with either heat paste, or an insulating material. I assume it needs cooling as it looks as though the meatsink was designed to come into contact with it. Can anyone confirm what it is? It's too small to easily put any custom cooling onto.

Not sure what that would be. Photo?

[In-Fluence]

The little white dot on the left is where I'm talking about. It definitely comes into contact with a component, and it's clearly made for that purpose, so I'm a little baffled. I can't really get my card out atm, so not able to give a pic of the actual component. Seems to be running fine, but I'm growing wary...


As a result of installing the HR-03 I managed to get 1GHz out of the core...

Just about stable at 1.25v, and only a smidge away from 20K

[generics_user]

i just ogt my arctic cooling L2 PRO as there was no way to fit the twin turbo into my V350 (you can cut off the fins on the left hand sight and bend the heatpipe forward but the chip has been moved too far to the top edge so no huge cooler for me

the L2 does a great job and keeps my 5770 @ 60°C under load with 20% fan speed

pics of my setup will follow this weekend along with some overclocking (i'll remove my x-fi for this as it sits right above the gddr5 memory; mATX is a PITA to work with but i need a movable box

[pr@$r1g]

^^^ post pics of ur card with some furmark ,so that how L2 pro works .I have also ordered L2 for my 5770.

Many sites are saying the same. ReverendMaynard test doesnt show anything. 100% fan test pretty much useless (more like which fan does spin faster), expect if you really want noise rig.
They are very different coolers and better efficiency cooler are also silencer(if fan isn't ed up). If you are intelligent you can even know why v2 could be better.

[ReverendMaynard]

I use high fan speed because I want to get the most out of the cooling. The V2 was crap, and it's gone because it died. If that's better, then awesome for all of those sheep that believe reviewers lol.

Sapphire's hd 5770 vapor-X is now available in the UK.

Your V2 is the hottest I've read about. Everyone elses (including my own) run much, much cooler than yours did. It must have either been faulty or something went wrong when you were playing around with the heatsink/TIM. This is also backed-up by the fact that it's now dead.

Here's how a fully functioning V2 should perform - I ran a 100% fan test for a giggle, GPU @ 1GHz, temps taken after running through the 3DM06 Demo:

Max temp 45 degrees.

[pvhk]

My HD5770 V1 xfire does not run to hot on my JR P45 with 2 very close pcie slot:

56°C for the upper card & 52° for the lower fan@80%

[Theorw]

I know what u are talking about...Yes it needs cooling this little chip man!along with the two in the end of the card,that used to have air flowing through holes of the main blower..Cool them too!

[In-Fluence]

Thanks for your reply, seems like I'm gonna have to hunt around for something suitable. It's a bit of a b*tch tbh, I don't know of anything small enough to help cool that whilst running my HR-03 on it. Annoying thing is, thermalright's site says it's compatible (without the need to buy extra bits). Luckily I haven't put much more than 1.25v into it, so I doubt I've pushed it too far, but not having that component cooled is a concern.
I'm acutally tempted to put the stock sink back on, and put the HR-03 back on my 8600GTs and use it as a physx card, but I doubt it would make a huge difference, nor do I like the idea of having ATI and Nvidia drivers on the same system

SonDa5 - I see you've got a HR-03 on yours too - did you find anything to cool that little component I'm talking about?

5770 VRM design is overkill (that's why manufacturers are switching to custom pcbs...)

i have no issues without any cooling on these digital vrms + ram with my small POS accelero L2 (this is on stock)

a small fan directed onto these chips should be more than enough

[bran]

My V2 gets ~65 degrees during Furmark with fan @ 40%, card is running @ 960/1325 with 1.225V. This is in a Antec 900 chassi with Noctua P12/S12 fans, and top fan @ medium.

I'm afraid it's not the VRM's or that area we're talking about. There's a tiny part about 1/3 of the way along the flat edge of the card which is covered in TIM from the stock heatsink (like I tried to illustrate). I haven't really tried to identify it, but it has a shiny surface, like glass. I can't think of anything small enough to cool it easily barring a bit of tin foil glued onto it!

[jooelhoglund]

I wonder which cooler is best



or



The second card have bigger fan and heatsink and the first one right ? but it doesn't blow out the air out of the case like the first card

I really want a test there these two card coolers beeing tested , someone have a test ?

So which should i choose ?

If not se the pictures

Have a read through this thread to see the evidence and read the debate. Although both coolers are great, I think it's fairly safe to say that with one or two exceptions, the V2 cooler performs better despite being cheaper to produce.

Both coolers do a good enough job though so it's not worth worrying about really.
