Arctic Cooling Accelero Xtreme 7970 Graphics Card Cooler

Great bit of kit, does need care and patients to get the best out of it.Now l have it fitted the cooler here are some figures:Well after using the little tube of thermal glue on the L shaped heat sinks on the right hand side line of VRM's as well as the top left VRM l get the following:Vrm 1 @ 80 maxVrm 2 @ 68 maxCore @ 67 maxAll after 1 hr of playing World of Tanks.All other fans in case at silent.A lot happier with the temps using the glue and fitting the L shaped HS onto the RHS vrms.The graphics card is running at the following clock:GPU @ 1050.Mem @ 1500.VDDC @ 1.2ish V.This is the AMD bios (1GHz) upgrade stock settings.Using TRIXX to adjust the fan profile to ramp up the fans from 20% as soon as the GPU hits >30 'c all the way to 100% if the GPU hits 80'c.If you get the two part mix glue it take a good 24 Hrs to set, however the cooler turned up with the newer glue which takes 60(ish) mins before you can fit and use the card.There are plenty of guides online on the best positioning of the heat sinks for the RAM and VRM's.You also don't need to use the thermal glue on the RAM chips, Akasa double sided thermal tape will do the job just as easily, however to get the best temps on the VRM's you need to use the glue.

amazzing temp drop results highly recommended to all 7970 users as it destroys the stock heat sink by a million miles

I bought this cooler for use on a Sapphire HD6970 2Gb card. Removing the noisy stock cooler was very easy (see U-tube videos) it took about 10 minutes. Then as suggested by the instructions I cleaned the ram chips with a rubber erasure to remove any residue from the sticky pads. After which I used some Isopropyl Alcohol (IPA) on All the chips to be fitted with heatsinks. It's important to ensure the chips are clean before you stick the heatsinks on or they may fall off! Also do the GPU chip.You will find a vast array of heatsinks included with the kit, you wont need them all, just the ones intended for your card. My cooler came with the new single tube glue which was easy to use. They claim a setting time of one hour, I left mine for 2 ½ hours before I moved on to fitting the fan assembly. At the time my room temp was 30c so I guess it would have set OK in an hour, I just wanted to be sure they were on to stay!Apart from the heatsinks for the ram chips, I fitted the 5mmX 25mm heatsinks to the very small bank of chips (to the right of the ram chips) which run from top to bottom of the card, four heatsinks required. Then another ram heatsink (15x13mm) to the embedded multi sided chip on the right center of the board, looks like a controlling north bridge?I then fitted the four little white spacers onto the GPU mounting holes, the four black ones goes on the rear of the card (along with a black sticky pad), note it maybe different for your card make sure you use the correct spacers. When you fit the main cooler please ensure the copper block IS in contact with the GPU chip or your going to burn your card out real fast! Also ensure the cooler is not touching anything else or it may short out.Don’t panic there is lots of room to fit this cooler, just take your time & do it right check everything twice!There are two power options for the fans, a 7v connector or a 12v connector, it's so quiet on the 12 volts theres little point in using the 7v.Mine works very well indeed, with the stock cooler on manual fan control set at 50% it was noisy, at 100% it was like a jet taking off, but now you just don’t notice the three 90mm fans, which run at low rpm so are super quite, eq to about 15% on the stock cooler under manual control. It's dropped the temp down to 37c at idle (30c room temp!) plus about 43-50c under high work load. I'm well pleased with it, a great buy!The only thing I would say is that Arctic market this as a “7970” cooler, but it will in fact fit a large range of graphics cards which I feel if Arctic had made that fact clearer they would sell many more than they currently do.The packaging states it fits : HD 7970, 7950, 7870, 7850, 6970, 6950, 6870, 6850, 6790, 5870, 5850,5830.Also don’t expect much (If any) help as to what heatsinks fit what chips, regardless of what card you have, just remember you wont need them all. Use your common sense.Good luck.

I received this card today, and fitted it straight away. I took my time with it, watching youtube videos and reading articles explaining how to fit it, as a result, fitting took me about 1hr and a half (excluding the time waiting for the thermal adhesive to set.)Fitting was fairly simple; remove the stock heatsink, clean the components, apply the thermal adhesive and fit the tiny heatsinks. Wait 60minutes for it to set, and then screw on the main heatsink and fans. DONE!What turned the 1.5hr job into a whole evening job was modifying my case to fit the card....the heatsink is 288mm long, however it does not fit exactly like the stock sink - about 3cm are wasted on the connection end, which means that when the cooler is fitted to the card (a 7950 in my case) it measures a whopping 315mm!!This was a problem for me, as my case supported GPUs of up to 290mm. As a result, i spend the evening removing rivets to remove the hard drive bay that was not designed to be removed.Eventually though, i finished the job, and my temperatures are amazing, not to mention the silence in which it does this!From mining at 75 - 80degrees C, with the side panel off, multiple auxiliary fans pointing at the card, and the stock cooler running at 75% which sounded like a hairdryer, my temperature is now 50 - 51 degrees C, with the side panel on, and the card not making much noise at all.The heatsink is huge, which helps spread the heat to a large surface area, but it's the fans of the cooler that impress me the most - they are SO quiet, that i am able to run them at high speeds (80% speed is quieter than my other case fans) which results in the epic cooling performance.Fitting this cooler requires disassembling your GPU to its PCB form, which truly isn't that daunting, but for a novice the potential to mess things up might put them off. I'd urge you not to be put off, but simply do your research first, in fact, even the included instructions will suffice, but for peace of mind, what some videos on youtube.Note: the pros are few, and the cons are numerous, but the pros are BIG, and the cons are somewhat negligible. For me, the pros FAR outweigh the cons that i'm placing an order for a second one (for my second card in my crossfire PC) tonight!Pros:- VERY good cooling - the core GPU temp has dropped 25 - 30 degrees C, and VRM temps don't exceed 70degrees.- well - stocked kit; you get plenty of different sized heatsinks to ensure that you will be able to fit the cooler to a wide range of GPUs/- VERY quiet fans, that can be set to run at a constant 80+% speed without producing much noise at all.- CHEAP! at £35, you'd be a fool not to! (unless your case can't fit it)Cons:- heavy; it looks like it strains the PCB a bit, as it is only supported by the PCI slot and the two screws at the end which attach to the case. be careful when transporting your PC.- LONG; overall length is 315mm on a 7950, but even more space is required in order to get the GPU into the case diagonally first. I would only recommend this cooler to people with cases that have removable hard drive bays.- fiddly fitting, may scare novices away- THICK; it takes up 3 PCI slots, but would ideally take up 4 (to allow extra air flow to the fans) - that said, I will be buying a second cooler for my crossfire setup - i'll report back how the top card's temps are, once fitted, (currently at 88degrees C)- not the best looking cooler around - some cards have really attractive aftermarket coolers, this one has a tacky looking label on the side, but other than that, it just looks component-y with heatsinks and PCB visible, which isn't too bad.
