• Arctic Accelero

Accelero Twin Turbo II is a silent cooling solution at load. Its universal mounting design offers wide compatibility on different AMD / NVIDIA models. It also equips.

We all know that the stock cooler does it's job as long as you 'tweak' the fan settings to decrease those horrendous temperatures but at the expense of silence. More cooling = more noise. Anything above 50% fan speed begins to get very annoying. At 65% it sounds like a jet engine for me at least. Accelero TWIN TURBO Main features. Unmatched cooling performance – up to 120W.

Efficient heat transfer via 4 heatpipes and 30 fins. Two ultra quiet 80mm fans with low noise impeller. Patented fan holder eliminates the buzzing sound. RAM and voltage regulator cooling. SLi and Crossfire compatible.

Pre-applied MX-2. Lightweight, transport safe. 6 year warranty.

Now for the testing. I do not have screenies or picture anymore. My super duper testing was the following: Check idle temp with GPU-Z, Run 3Dmark06 'Firefly' test loop 6 time in a row and re-checked load temp. Not the best, but it will do. STOCK FAN running 35% (2400RPM) 51 IDLE / 63 LOAD Not too bad!

Btw, I had AS-5 on stock cooler to help. Twin Turbo running 75% (1800RPM) 43 IDLE / 47 LOAD WOW!

I'm still using the CCC fan 'tweak' trick. The RPM is much lower then other one. That's a 33% difference! The cooler is super quiet. I tried setting the fan at 35% but the RPM speed in GPU-Z was really messed up and i had similar stock temps at that speed, too low i guess. Remember that the thermal paste has not truly set yet. So temps should improve with time.

Overall, I'm really impressed with the Accelero Twin Turbo. For a single card user like me. It's pretty 'Cool'.

PRO's: Great cooling Low noise Lots of heatsinks 3 pins + 4 pins to connect directly to the card. 6 year Warrenty CON's::shadedshu Uses 3 slots May interfere with CF bridges 4870 requires twinking. I'll leave the scoring stuff to the real review guys.

System Name Derp! I voided all possible warranty on my sapphire 4850 because i cut up the heatsink to make some modifications.

Lets just say that i re-enforce the heatsink on the memory chips and use the copper heatsink(reference heatsink) to cool the pwm. Overall the twin turbo rocks, but if you have crossfire, you'll have to put it on the second card. There's no way you can put it on the first card.

Now i need another heatsink to cool the first card. I wish i took some pictures. Just to paint a little picture, the first card with ref heatsink is idling around 50+ degree. The second card with the twin turbo idles around 44 degree. On a cool day, the second card will be even cooler. I would definitely recommend the twin turbo as it's a budget card from this online vendor, aero cooler something.

I believe an aftermarket cooler on the 4850 is almost essential, mine is the Asus reference. I was running Crysis on high, which the game recommended, and was getting aweful stuttering in game play, sometimes freezing for seconds at a time.

I installed an Akasa Vortexx Neo (mainly cos the Accelero S1 seems to be out of stock across the UK) and saw temps come down from 58/78 (and loud) to 35/54 (v quiet), and DX10 games are now fully playable. I believe the Arctic Cooling Accelero S1 Rev.

2 will better those temps easily. I assume the high temp was causing the RAM freeze I have read about elsewhere. Take a look at the Coolink GFXChilla also. Hey, can you post a screenshot of the latest Gpu-z on load idle?

I have an HR-03gt cooler on my hd4870 and as u can see my vddc are dying(or probably already dead, since i seem to be having some graphics issue in some games), i want to know if the AC cooler fixes this because of the two fans(apparently the thermalright t-rad is supposed to fix it too but that's not available anywhere here). Though seeing your 63c load temp with stock, i might just ask the shop to return to stock cooling with a proper thermal compound and save some money since that's not a bad temp the load is from crysis: warhead if you're interested ^^ the most demanding game right now pretty much. My Accelero Twin Turbo Review: I bought an Accelero TT for my 4870.

In an Aerocool AeroEngine Plus It runs wonderfully with only 1 card in: 45 degrees C Idle 55 - 60 Degrees C Load 50% fan now when I install a second card there is only 1 or 2 cm between fan modules and the second card. This causes cooling performance to deteriorate rapidly Temps reached 80 degrees C on the top card with the TT and a 120mm fan blowing on it with moderate load. With the card in the bottom slot it's a different story - 50 degrees C idle 60 - 65 degrees C moderate load in Crossfire SO at this point I'm going to put the TT in the bottom of the case and have my other 4870 using stock cooling for now. Anyone tried the Thermaltake Duorb on a 4870??? The biggest problem seems to be air flow - TT can't get enough cool air when its in the top slot so it just keeps getting hotter.

In the bottom it's getting cool air from the bottom of the case. Again it is wonderfull as long as u use 1 card or have it in the bottom of the case.

Arctic Accelero

Hey all, I recently purchased an Arctic Twin Turbo II cooler for my GTX 680 FTW card, as it was running pretty hot already and Summer is almost here. All the reviews have stated that the instructions were difficult and I can confirm that they are. The cooler is so generalized that it is difficult to determine what goes where. I was hoping someone could take a quick look at the instructions and clarify what step 4 means: 'Apply the insulation tape onto the circuit components in order to prevent short circuit caused by RAM and VR heatsink interference.' Where does this tape go?

I don't want to fry my card! Also, if anyone who has done this with a 680 is reading this and happens to have a picture of where the heatsinks go that would be great so I could double check. It's my first time doing this.Justin DIRECTIONS.
