Didn't get anything from OCUK actually, lol
Just the S1 and some Sekisui thermal tape to use on the ramsinks that come with the S1.
Will be using some MX-2 that I did buy from OCUK on the GPU

I wont get my accelero until mid next week though, so it will be a bit of a wait
well i should have mine by sat or monday, and i have the S1 and extra ram sinks waiting to go on, will pick therm tape up tommorow. So i'll do a step by step with piccys as soon as it arrives. It'll be my first attempt at VGA cooling so hope I dont screw anything up.
Put a Zalman VF900 on my 8800 GT and saw load temps after 10 mins artefact scan in ATI Tools drop from 88 degrees to 52 degrees (minimum fan speed). VF900 costs more than the S1 though, but I happened to have one on an old X1800 XT card I could recycle (including ramsinks) so it cost me nothing this time round. Clearly the 8800 GT doesn't put out much heat.
I wouldn't bother replacing the stock thermal paste on the S1 - It apparently has MX2 pre-appliedWill be using some MX-2 that I did buy from OCUK on the GPU
. It certainly works well on mine.
I installed an Accelero S1 on my Inno3D 8800GT earlier today. I made the purchase because my temps would reach almost 90degrees with the cards stock heatsink. Results below.
Stock Heatsink and Fan Settings
Default clocks (600core/1500shader/1800mem)
IDLE=53
LOAD=84
Max Overclock (702core/1687shader/2000mem)
IDLE=53
LOAD=89
Accelero S1 passive
Default clocks (600core/1500shader/1800mem)
IDLE=39
LOAD=69
Max Overclock (729core/1720shader/2040mem)
IDLE=40
LOAD=73
Accelero S1 plus 92mm Akasa Amber fan
Default clocks (600core/1500shader/1800mem)
IDLE=36
LOAD=43
Max Overclock (729core/1782shader/2100mem)
IDLE=36
LOAD=45
Here's a Riva Tuner image of the Accelero + 92mm fan with max OC.
So, the Accelero has dropped idle temps by around 17degrees and load temps by a staggering 41degrees. This was better than I expected but the thing that surprised me most was the increase in memory overclock. With the stock coller my memory was "just about" stable at 2000MHz. Without any ramsinks (naked) it clocks much furthrer. I can bench at 2160 on the ram, but have used 2100 with complete stability.The core and shader also overclock further, but I think voltage is holding me back now.
For just over a tenner the Accelero is a great buy for any 8800GT owner. Buy one quick before everyone puts the price up
How does this translate in frame rates compared to a factory clocked 8800 gt and is it worth the trouble going ahead and fitting the Accelero bearing in mind you might be nobling your manufacturers guarantee? Also, with the revised Gts just around the corner would it be really worth the effort in modifying the GT for perhaps so little gain?
Depends. I plan to do this to mine just to silence it. For that reason, yes. And for performance, and the fact ive still not seen any details on a 320 meg GTS, the new 640 card will be in the £250 price range, it make financial sence.
are they easy to instal?
Also, did you get higher overclocks with it compared to stock?

Fair point well made
I posted some benches of a stock vs overclocked 8800GT here. The clocks shown there were not quite as good as I am getting with the Accelerp, but overall gains are probably around 10-15%. It is the difference between being slower or faster than a GTX
. Certain games (eg. Crysis and Oblivion) show great gains when the card is overclocked.edit: Oveclocking allows me to play Crysis at 1680x1050 on High settings. You can really notice the difference from stock settings where the game is much more choppy. Those extra 4 or 5 fps mean a lot in Crysis.

Cable ties, but first, fix 4 pieces of velcro on the 4 corners of the fan that will be in contact with the S1, good for noise/vibration insulation
if its bought at a non competitor shop? for example Partners... im unsure as to the rules....
what i'll be using is double sided sticky pads for the corners of the fan... any stationary shop will sell them, and tie wraps 100 for a quid at poundland.

Thankyou 55buk
Piece of cake to install. I had a few artefacts at 700/1000 (stock voltage) in 3DMark06 though, like where part of the screen would flash black for one frame. ATI Tool artefact checker was clear though. I'm not a big overclocker though, it's possible that could have been cured by going higher as used to happen on the GTS. 650/950 was fine btw.
Try clocking your core and ram independently of eachother and see which is holding you back. ie Leave ram at stock (900) and see how far the core goes.
