(please excuse the image quality, it was my phone and I anxious to get installing)

Hey folks, I was getting damn annoyed with the cooler on my X1950 Pro, it was a big dual slot lump and it did my head in when it was on, especially as I'm temp without speakers :(.

So I decided to buy the Accelero S1 as I liked the idea of silent cooling, and there was always the option of adding on the turbo module if the heatsink wasn't up to it alone.

Today I received a nice box, containing the cooler, and my first impressions were of the sheer size of the beast!

Obviously the next step was to take the card out of the PC, which occured with some annoyance at the PCI-E holding clip which seemed to be quite a failure on my DS3. Anyway, eventually it came out, so here's a shot of the cooler and the card next to each other, for comparison.

Removing the stock heatsink came as rather more of a challenge than I expected, the screws were tiny, and obviously done rather tightly. I ended up using a small screwdriver twisted with some pliers to get the backplate, and cooler off.

After, I cleaned up the remarkably mucky core with the usual tools, and then things started to get a bit tricky.

Arctic cooling supply a voltage regulator cooling plate, to replace the ones that are apparently on reference X1950pros. Mine is not reference, apparently, as the place where this was intended to sit had a nice capacitor in the middle, and a strip heatsink attached already. I looked on the net and found that this wasn't a "required" cooling device, and therefore I ignored it, and carried on without.

The next instruction also gave me trouble, another "strip" heatsink was to be attached to another part of the voltage regulation system, and would be secured by two holes already in the card.

On my card, only one of these holes existed, so a bodge job was in order. I put the first screw through the hole, and for the second...well, the image speaks for itself

Ramsinks next, nice and simple, went on without a fuss, and they look acceptably sticky to stay on for long periods of time.

And now time to lower the card onto the heatsink, probably the easiest part of the installation actually! just line up, and screw away. There was some plastic clips to attach to the board and metal, but it can do without them, I attached only one of those.

Finally, I slotted it back into my case, which was a bit of a struggle due to the increased size, but didn't really take that long.

Now to the more interesting part, temperatures!

With the stock cooler my old idle temp was: 40c

With the S1 installed, my idle temp is: 32c

Under load, my stock cooler was holding the card at: 66c

But with the S1 installed, load temp was a remarkable 47c

The temps speak for themselves, an 8 degree reduction at idle, and a 19 degree reduction under load, and this is completely fanless, in a system with 2 Yate Loon 120mm fans.

I'm incredibly impressed, especially for the price, and the only downside would be the installation, which takes longer than expected, and is problematic should you have a non standard card.

Not much else that can be said!
Cheers :)
 
Yup got one of these, with it overclocked all the way to the top doesn't go above 52. Got a 12cm fan strapped underneath though.

I didn't allow the heatsink to touch the core until I screwed in all four screws, push it down turn it over then screw them in fully- so doesn't move around and knacker the contact.
 
That is very impressive, i have ordered one and hopefully it is arriving this week.

My stock cooler hasnt really been performing that well, and a couplr of times whilst playing AOE3 my gaem has locked up due to the gfx card getting 2 hot.
 
same here, using one on my x1950pro agp, be warned though, in your pic i see one of the voltage regulator thingys with no heatsink on. it needs to be heatsinked since it does get damn hot and has been the cause of a lot of failures.

Not sure what to put on it though, the stock one doesn't fit my card.
 
Great bit of timing, since yesterday I've been debating whether or not to upgrade my stock X1950pro cooler to one of these!
At idle the stock cooler is the loudest part of my rig, gonna get the S1 I think, didn't realise the ram sinks came with it!
 
Got one of these on my x1900xtx, handles it no problem. Getting quite warm to the touch after an hour of ut3 gameplay (still playing) but this is in absolute silence which is fantastic.
Installed the S2 on my brothers 7600gt today as he was moaning about the noise of his machine. Removing the whiny leadtek cooler that ran at full pelt all the time for something that makes no noise and kept the card so cool I was worried that there was something horribly wrong was a good move, these coolers are great. :D
 
They look good.

I have an S2 sitting here next to my desk with nothing to put it on. I bought it for my HTPC and the case top won't go back on with the Accelero fitted! To be fair it does tell you to measure this before buying one ;)

This seems to good to be true- can this be used when OC'ing the x1900 to max CCC allowed temps (I've got fairly good case air flow)?And only ~£20 to boot? Great!
 
Hey HXC! :D Nice to see my old x1950pro still serving you well :D


Haha yeah... it's doing alright. I've got the upgrade bug and may well just switch this over to my parents system and grab me something else, although the noise will annoy me a bit... I'll see.
 
I have just got one of these S1 coolers and have to say the results are amazing to say the least.
At idle, the stock HSF was keeping the card at around 50-55 with the fan control manager in ATiTool. The S1 is making it idle at 30-32 degrees.
Result: 23-25 degrees drop.
Where it is shining even brighter is when the card is under load. With the stock HSF the card was going up to around 85 degrees again with the thermal control kicking in. The S1, at the moment, with AOE3 running on the welcome screen and in game the card is going up to 48 degrees max.
Result: 37 degrees drop.
This is with the card running passively and luckily my side fan fits (just) right next to the card so is blowing a nice stream of air over it.
Including postage from OCUK, the cooler cost £20, amazing value and is highly recommended.
Quick note: buy separate ramsink adhesive as the stuff supplied already attached to the ramsinks is a bit rubbish (4 are currently not attached).
 
The 8800GT is supposed to have 7800 mounting holes, and the S1 fits the 7800... as it only covers the core (the 8800GT core is smaller than the GTS/GTX) it should be fine.
 
Will be very interested in that one! I don't think I'll ever be able to move away from silent graphics cards now I've got this in there.
