I've been following the mild debate over whether the 8800GT and other current-gen cards require heatsinks on their RAM and VRM components when used with an S1 or S2. I had heatsinks on all of the above when I was using the S1 with my old EVGA 7900GTX, but I have now had the S1 + Yate-Loon 120mm fan on my 8800GT for about a week. Using no additional heatsinks at all, I've had no stability problems in any 3D games or running RTHDRIBL tests for a few hours. GPU temp also hasn't risen over 55 C or so.
I use Speedfan to control the speed at which the fan mounted on the S1 blows, and I let it go around 400-500RPM at idle and 1000RPM or so under full 3D load.
I'm not saying my experience means you don't need those RAM and VRM heatsinks though, because who knows what the effect on those components might be over the long term. I would say, however, that if you're not using the S1 passively, and aren't overclocking the card, and the thermal design of your case is inherently sound, then you will probably be OK.

You're probably right but why wouldn't you put some heatsinks on the vrms/ram? Arctic cooling sell a pack of 8 sinks separately for 5 or 6 bucks. I've put the accelero s1 on two cards and they stick great. If you have articlean they really really stick. Once you stick them on it's hard to pull them off. I put it on the 3850 and temps went down from high 80's at load to high 40's. A 40 degree drop. That's probably the most extreme example of temperature drop though because the default 3850 stock cooler is only a single slot cooler with a fan that never seems to spin more than 25%. As a result it's really quiet but doesn't cool very well.Ryan Norton wrote:

gigabyte 3850 256MB pcie here (specificaly gv-rx385256h-b)
removing the stock cooler was easy
cleaning the goo on the gpu was easy
accelero is well built, the lightness deceives you
of course it is easily bent, the ultra120 is easily bent too, what would you prefer? double the weight ? or 2mm thick fins? i say it is well built. esp. for its money
right now i salvaged a pci-agp bridge sink from an agp 7600gs... i will try make it stick on the 8 vrms it fits rather nicely
ram heatsinks stick well enough i guess
sippin my coffee and installing a cooler
next up two 160GB hdds in raid (mirroring, for faster access)
ah, what better way to celebrate my birthday
Just recently noticed this: http://www.aijaa.com/v.php?i=6056950.jpg

So there's A LOT of heat increase. I use Arctic Silver Céramique Thermal Paste for the GPU. Yesterday I took the card off and blew dust away, but it didn't help. Seems that it's time to change the thermal paste...

Well now I took the 2008 paste away and put there fresh Arctic Silver Céramique Thermal Paste.
Here is the result:

mid: yesterday with old paste
below: today with new paste
Still not good enough... Perhaps a bit more paste would be required.
