Finally someone tried and reported back
. What did you use as load the card? Did you connect the thermalright fan directly to the video card header? Last, if you don't mind (and feel it's safe), can you run an older version of furmark (like 1.6.x) and report temps. Thx.
Actually I've installed Shaman on GTX 580 just yesterday. I've never changed stock cooler on any VGA and it took me about 3 hours, but I would say that installation is pretty easy EXCEPT ! disassembling the card if you do not have optimal screwdrivers (I could remove all Phillips P0 screws easily except one, which turned out to be impossible so I couldn't test theory mentioned in this thread viewtopic.php?f=19&t=61153
which I really wanted to try out) Luckily I bought two different Torx T6 screwdrivers because again - there was one T6 screw which was impossible to remove with screwdriver that worked on all other T6s (so the second screwdriver saved the day)
But even bigger pain was fitting the RAM/VRM sinks - that was really annoying. Also the 140mm fan doesn't fit into VGA, the only way I was able to connect it would be to use 4pin on MB (not a good idea, because than it starts on 800rpm) or via 7V 3pin reduction - which is what I ended up using.
I have ordered from E-Bay a connection cable which will let me plug the 4pin fan header into the graphics card fan header
good - so there exists something ? I was looking in local shops and couldn't find anything. More details ?
Now about acoustics & temps
Well on 7V the Thermalright fan is MUCH quieter than the stock cooler at idle (40%). (Actually when I disconnect all fans on the PC I can still hear buzzing of the GTX 580 card, with closed case it seems to be no problem for me, but it could be bothersome to someone with sensitive ears. Seems like GTX 580 is not silent even at idle and passively cooled.)
It could be that with the exhaust and top fans on my p182 - 2x Nexus 120mm @7V are actually louder than Thermalright @7V because they are not covered by case side panel - but I'll need more time to be sure. Another good thing is that @7V I measured temps on GPU that never stepped above 85 C full load and closed case. Not so good thing is that @ 7V sometimes I can hear slight clicking noise coming from the fan, but just sometimes, I still haven't decided how much is this a problem. When I connect another 9V reduction - on the already used 7V reduction
then the Thermalright fan is still able to spin and I would say that when compared to noise floor of my system it is virtually "inaudible" (no clicking etc). Yet even with this double undervolting it keeps the GPU temp at 93 C full load. I even tried gaming and saw no artifacts or other anomalies, I think 97 C is max safe temp for GTX 580 so 93 C is a bit "on the edge". The worst thing about the performance (which was expected) is that the temps inside case are now much higher as there is no blower exhaust fan as on the stock cooler. This results in CPU temps now being about 6C higher than on stock cooler at equal load. I've tried Dirt2 which is one of the games that can utilize more than 2 cores and I got 65 C on one core which is not that great - luckily there are not so many games that can use all four cores at full load
I still haven't tried my original idea with mounting 120mm fan into p182 GPU position and seeing if it helps somehow with case (and hopefully VRM) temp. Oh and I also can not report on VRM temps, but seasonic x-750 even at full load seemed to be fine and was not ramping up the PSU fan. I still need more time to evaluate acoustics etc. properly I will probably write more detailed review sometime next week, or at least sometime...
