has anyone used a Thermalright HR-03-GT VGA Cooler, no one seem to have comented on it.
installing the Accelero S1 is childs play, no offence but anybody who thinks otherwise perhaps hasn't changed card heatsinks much?
yes they're both good solutions, pick your poison
I've fitted an Arctic Silencer to a 9800 and a X1800XT, a generic cooler to a 6600GT, the S1 and my current Vortexx.
The S1 was by far the most annoying to fit. If you consider it child's play, then the Vortexx could be considered to install itself
i just don't understand how anyone can find the S1 even mildly difficult to install, unless you're speaking about those plastic support clips exclusively????? which yes are a PITA and totally aren't needed at all anyway.....fitting the actual heatsink is a breeze like any other heatpipe based cooler.
i'd like to see gpu-z temps also, VRM area gets scorching on my cards especially overclocked........sinks and active cooling are not even debatable.
As has already been stated those VRM's must be getting kinda toasty? unless the Votexx with it's vent is actually cooling them well enough?
I have read that the VRM's on the HD4850 are of a cheaper variety than what is featured on the more expensive HD4870. The side effect of these cheaper parts is that they heat up a lot more.
If yours are not getting cooled enough they will probably run fine for a duration they suddenly burn out!
I am waiting for these new revison S1 coolers to come out finally as they include everything you need cooling wise.
People who already own Vortexx cooler may well want to fashion/mod themselves some small heatsinks and stick them on with double sided frag tape or you can buy premade heatsinks but I dont think thats money well spent.
Moddin some would be quite straight forward if you got a some old bits of heatsink laying around (I call this Dremel food!), it's just a small bit of metal that can absorb the heat from the component and then get cooled down by the airflow. Some people have even hacked off the original VRM heatsink that came with the stock cooler and used that!

haha i was thinking of doing that myself, but i have an old artic cooler for a 6800Gt laying around some where , i'll dig that out and see if i can chip that up first
Do we have any update on the S1 coolers being sent out, do they include all the required heatsinks inc. the VRMs?

by the time you actually do anything your card will be passed over to the mid-range section.
buy a pack or 2 of £3 sinks = job done....the S1 sinks are crap anyway.

I used a combination of zalman jobbies and hacked up an old gigabyte southbridge and stuck them on with some akasa tape. Works a treat and i've got both 4850s up to 690/1150 stable. Thats using a pair of voretex cooler btw. I've also got a akasa voltage adapters connected to the fans so they run at a constant 10v. I tied them at 5v and 7v but the cooling wasn't good enough and I find 10v gives sufficient cooling and low noise. Got a pic floating around on this forum somewhere come to think of it.

just purchased a S1 for my 4850, I have fitted one on a 8800gt in the past and the sinks wouldn't stay stuck. Is this still the case should I get some decent tape as I need to add that to my order asap? Also with the VRM's is it just a case of hacking up an old heat sink I have lying round?
Cheers,

Dammit. I can see I'm going to have to get the hacksaw out tomorrow. I'm watercooling my 4850 atm and have no sinks on the VRM's.
Will see if I can find some old socket 7 mobo sinks to chop up first, but I only have a couple of sticky pads left :/

Hi,
I recently installed a 4850 Sapphire Toxic edition, which has the Zalman VF900 (and the sexy blue heat sinks
)It idles at 38 degrees and hits about 60 with standard clocks (675, 1100) so the VF1000 should run much much cooler!!
Example of temps using a quick stable OC.
I've noticed Sapphire have given up completely on the reference coolers for the 4850
The powercolor 4850 PCS looks awesome too Great cards!

GPU-Z sensor tabs wont show how hot the VRMs get. All 3 temps are on die temps.

Note this is for the hd4850 only. The hd4870 has additional temp readings (with latest gpu-z), one of which is the temp diode on the VRMs.

Mega bodge alert.
It started out ok. Correctly guessed the size of heatsink required and sawing through old aluminum was as easy as tough wood. My remaining 2 thermal pads were the right size too... until they ended up in a sticky fingered mess during insertion.
...so I resorted to arctic silver and quad tie raps
Now the whole point of not hack sawing through the original was so I could still rma if required. However cleaning off the arctic silver could be annoying. That said, there is always the chance they wouldnt remove the stock cooler on an RMA check?
Finally, all that effort and I am getting poo overclocks on this thing (all 4 temp readings fine in gpuz). Will do a bit of research on what can be expected.
Edit: Stuck a sink on the 5th pair of little chips further up the board now. I also wasn't using the mobo's pcie molex socket. One of these two changes has suddenly solved my slight occasional squealing problem it would seem.

well in the installation manual of the VORTEXX Neo is doesn't say anything about puting heatsinks on the vrm's.
also if u go to AKASA site it says:
