Radeon HD 5770 First & Second Edition Performance Comparison
Cooling capability comparison
As the two versions are not compatible with each other due to different power connectors, we could just compare those two separate graphics cards. Considering the individual difference that different GPUs may have, this benchmark is provided for your reference. On the other side, this also fits the users’ actual applications.
In addition to comparing the GPU temperature, we also monitored the temperature at some point on the rear side of the PCB and somewhere in the chassis.
We run FurMark benchmark to load the system, and recorded the standby and load temperatures respectively. The ambient temperature was kept at 24 degrees.
With equally high noise under load, the new revision outperformed the old one by 9℃ in terms of GPU cooling.
The new version cools the PCB more directly, so it comes as no surprise it outclassed the older one in this session.
The hot air dissipated by the second version of cooler still stays inside the chassis, which increases the case temperature by up to 0.7℃ according to our test. The increase of case temperature would have negative effects on the whole system including CPU cooling.
In conclusion, the new cooler delivers better absolute cooling performance for GPU and PCB, but it’s bad for the overall heat dissipation in the chassis.
At present the two versions of Radeon HD 5770 coexist on the market with the same price, so you may choose one of them as you like.

I’d pick the first version in a heartbeat.

Considering I use an open air case I like this new design. I will be upgrading soon to two 5770 and a PDC E6500 at 4GHz.

While the first version is much more interesting from a cooling/noise point of view, the reason that they are switching to the second model is due to lower cost. Haven’t you noticed how the cards equipped with the second edition cooler tend to be cheaper?

“The only difference is the additional inductor at the right bottom.”
– The inductor is present on the first board also – it’s just a different one.

The newer version makes sense:
- cheaper
- noticeably cooler GPU card under load (9 °C)
- somewhat hotter case (**almost** 1°C)
What would also be interesting to know would be the noise level comparison.

Got the second version running at 1GHz core at 1.225v, cools it really well. Never goes over 55 degrees in games and 65 degrees after running furmark for a while. There’s room to fit decent heatsinks to the RAM and VRM’s under the second version’s cooler if you want to, too.

I have bought a HIS 5770 with the new cooler.
Very good temperatures, and I have not problem with case temperature. If you have a 120mm rear fan plus side fan (i haven an Armor+MX), the case temperature is very good.

What about crossfire, what would be better???

A HIS HD5770 “ICEQ+” … WOULD BE PERFECT¡¡¡

I’ve just gotten an Asus 5770 with the second gen cooler, and man, it is silent. It also seems to cool great, although I may have gotten lucky with a nice and cool GPU.
Only thing I hear in my case now is the air being moved, and sometimes the DVD drive – I don’t even hear the video card fan itself, the 120mm Antec Tricool case fans are louder!
As for temps, I haven’t been able to push the video card over 58 degrees Celsius at full load, running FurMark with Xtreme Burning Mode turned on at 1920×1200. All of this in an Antec 902 case, with fans positioned so the CPU cooler catches the most air, with the GPU cooler only getting air that’s been warmed up by the harddisks.
All in all, for the performance and silence I got with this card I’m very happy, and I’m pretty sure I’ll be able to do some proper overclocking on this thing.

i own 2 1gen 5770 HD’s and running them OC’ed on furmark i will not get even close to those temps they got. i have max 75C when running it for many hrs. i dont have any exclusive coolers on my comp. only stock cpu,gpu and psu coolers. so everything they say here is bullshit.

Hmm, mine 1gen ends up 86*C when running Furmark for a while and I have well cooled case. Rising the fan speed drops the temp straight down. Maybe I should replace the thermal grease. However the memory on top of the card ends up really hot, it needs some heatsinks in order to overclock the memory.

the 5770 v2 cools better than the 5770 v1. many people like the v1 because they think it looks better, but the fact is the v2 cooler is better at pulling heat away from the card even if it isn’t vented out of the case. If your case has adequate air flow, such as 1 or 2 case fans, you shouldn’t have a problem with heat staying in the case. The only scenario where I can see the v1 cooler as a viable option would be in a very small micro atx case.
The 5770 runs cool compared to most other cards, and won’t shutdown until it reaches 125c, but the max recommended temp is still 100c. My 5770 idles at 28-32c.. although most will find it to be a few degrees more. Honestly, unless you’re case is setup horribly and you run your computer in a very hot climate, it’s not going to come close to overheating – even when overclocked in most cases.

good day! noteworthy post, realy healped

Its like you learn my mind! You appear to know so much approximately this, like you wrote the e book in it or something. I think that you just can do with some p.c. to drive the message house a bit, but instead of that, this is wonderful blog. A fantastic read. I’ll certainly be back.
