Arctic Cooling Accelero Twin Turbo Review

I just got the Accelero Twin Turbo yesterday, here are the results
Temps measured using Catalyst control center & OCCT for assurance

--This is proof of my good airflow, as well as a before twin turbo installation

http://s321.photobucket.com/al...ssociate/Stock%204870/

--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

--Time for the presentation

--And now for the installation....

http://s321.photobucket.com/al...ck%204870/Instalation/

--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

Edit:
At 20% fan speed, I stoped at 80, it ran at 80 for about 2 mins til I heard weird quiet zap sounds from somewhere, probably the sticky stuff on the ram sinks, so I ended it there.

--Twin Turbo installed in case...

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, or if you notice any typos 🙂.
The variations in some of the temp scores were due to continuous fluctuation.

Thanks, and enjoy.

Im going to make a review of my new Xigmateck S1283 this week as well 😀
 
Alright, so I got me one of those puppies for my HD 4870 512MB. I put it on 7V and...

- GPU Temp 48C idle, 55C load - ok
- GPU: DISPIO, MEMO, SHADERCORE - sub 70C load - ok
- VDDC Slave - 70C idle... 120C load (ouch!)

Now, I put it to 12V and the VDDC topped at 100-ish, not so bad (similar to stock cooling) - but the thing is too loud for me then. I got A TRUE with a Nexus at 5V on my CPU and 4 other Nexus fans at 5V in my P182B case - everything dead silent. The VRM heatsinks that came together with the Accelero didn't fit that good... 2 out of the 4 could be attached and they covered the VRMs (one covered 2, the other 3 - perhaps 1mm too short here).

I don't want to melt my card but I want to keep it quiet. Anyone got any ideas how to fix this? Will better heatsinks help? Those here do cover the VRMs...

Any tips much appreciated 🙂
 
Great cooler, BUT not for 4870. It's impossible to cool down the VRMs ,even if the GPU and the memory is well cooled. The only safe thing to do is to try to use the stock red aluminium plate to cover your VRMs and ram chips. I don't understand why is everyone still buying these coolers, when everywhere on the web is written about the VRM overheating issue!?

OP, great review and all, but there are other components on your videocard that matters, not only the GPU, like the VRMs. Check their temperature with GPU-Z and see if you are still as happy as you are now. 😉
