I just got the Accelero Twin Turbo today, here are my results
Temps measured using Catalyst control center & OCCT for assurance
--My case has excellent airflow, all cables tied up together, out of the way of airflow.
--Room temp 25 Celsius, stock cooler, great airflow, one pci slot opened to act as small exhaust
20% fan speed, idles at 74C
40% fan speed, idles at 53C (21 degree drop, wow o.o)
50% fan speed, idles at 48C
After 50% fan speed is when it becomes unbearably loud for anyone
60% fan speed, idles at 46C
80% fan speed, idles at 44C
100% fan speed, idles at 42C
--Load temps retrieved using AtiTool
--GPU activity from 96~97% continious
--Room temp rose to 25.1 Celsius, stock cooler, great airflow, one pci slot opened to act as small exhaust
20% fan speed, loads at 105~106C
And I don't care what ATI says, I REALLY don't like that number :S
40% fan speed, loads at 93~94C
50% fan speed, loads at 83~84C
60% fan speed, loads at 74~75C
80% fan speed, loads at 69~70C
100% fan speed, loads at 66~67C
--At 106C I thought it would be fun to touch the pcb, I wish someone was there to stop me -.- cause owch....
This thing isn't as big as I thought, it takes the space of 2 pci slots
To my surprise, connecting the fan to the card itself allows me to control the percentage as well
So an exact fan speed comparison can be made, mind you of course, this fan is much less audible than the stock fan
At 100% fan speed, it's about as loud as the stock fan at 40~45%, which can be annoying for some

--And now for the installation....

--The ram sinks hold on fine, I held them on tight for 20 seconds to keep them still, the voltage sinks however, are another story, those things ticked me off. I took the sticky sponge stuff from the stock hs, placed it on the vregs, then put the sinks on em, and they finally held fine after 2 hours so far. I plan on replacing them, as well as the ram sinks, with copper ones from EnzoTech or Swiftech, for better sticking and cooling. And yes I cleaned them properly
--Room temp still 25.1 Celcius, Accelero Twin Turbo cooler, 2 pci slots used as exhaust
20% fan speed, idles at 50~51C
40% fan speed, idles at 41C
50% fan speed, idles at 39~40C
60% fan speed, idles at 38C
80% fan speed, idles at 37C
100% fan speed, idles at 37C
--At 20% fan speed, one fan literally spins 1 rotation per second, other fan spins about 5 rotations per second
--Load temps retrieved using AtiTool
--GPU activity from 96~97% continuous
-Note: These fans were obviously not meant to push below 60%, hence it stating 1500 to 2000 rpm; rpm is easily guesstimated from the naked eye at those lower speeds
20% fan speed, loads at 80C+
40% fan speed, loads at 57C
50% fan speed, loads at 52~53C
60% fan speed, loads at 51~52C
Fans become audible after this percentage
80% fan speed, loads at 49C
100% fan speed, loads at 47C

Note: At 20% fan speed, it got to 80 and stayed there for 2 minutes, then I heard quiet zaping sounds, probably the sticky stuff for the ram sinks, so I stoped it there just in case :S

Ram sinks were scorching hot at 20% fan speed as well, which is another great reason to use copper, even though 20% fan speed is pointless, since 60% is just as quiet, the silicone was meant for high temps, not sure the thin aluminum ram sinks were lol. But remember, fans are barely moving at this percentage, blowing on it would literally cool the heatsink better than the air coming out at this speed, so it's practically a passive temp
A 20C degree drop at max fan speeds, the fact that the fans are so quiet is a great plus, obviously
So that's it, tell me if you want extra pics of whatever type, or anything else to be included.
The variations in some of the temp scores were due to continuous fluctuation.
Thanks, and enjoy.
