BurnOutPC.com has posted a review on the Arctic-Cooling Accelero S1

I must say, for only 20 euro's. You get a very good looking cooler that performs excellent. The installation is real easy, too bad the heatspreaders didn't fit. But Arctic Cooling can't make it compatible with every type of videocard available on the market. I'm now running my computer with only the stock cpu cooler making a tiny bit of noise. The inside fan is running at it's lowest speed and I have no problems with the card overheating. Crysis, here I come Overall a very good cooler for only 20 euro's, what more do you want.
