There are no aftermarket coolers for 4890, now. Even if the mounting holes for the GPU, are the same as for 4870, you have nothing to install on the VRMs and don't think about putting just some crappy little ram heatsinks on them, because it's not gonna work.
And I don't understand what you are saying. The fan profiles that comes with the card, implies the fan to spin at 70-100%, or you're forcing the fan to spin that fast? I know someone who has a Powercolor 4890 and the fan never gets over 38% under load.
pffft... slapping as you say "crappy little heat sinks on them" will work just fine as long as the case has good air flow. That AC cooler with a good (120mm) fan and sinks on the VRMs will probably keep the VRMs a lot cooler than the stock sink would. Most aftermarket coolers only cool the GPU and use "crappy little heat sinks" to cool the RAM and VRMs. With the 4870 and 4890 being so alike I'm sure using a cooler compatible with the 4870 on a 4890 would work just fine. Both of the coolers I listed were out long before the 4870 was ever on the market and it is compatible with it so it's not like they were made for the 4870. They just made sure it fits and cooled well enough to call it compatible. I don't know about the AC cooler but that zalman does come with it's own RAM sinks and I use them to cool VRMs on a 8800gt and they work just fine. 4th I'm done so save your breath.
I have never used these but it looks like a good deal

The sad thing is that you have no idea about what you are talking about. Please , make a large google search about people that used the Accelero S1 with the crappy little heatsinks onto the vrms, on a 4870 and see what are they reporting: VRM temps in excess of 120 C. And it's not a problem of airflow, it's a problem of large heat exchange surface, something that the crappy little heatsinks lack. It has been discussed here on these forums 1000 times already about this problem and yet you never heard of it and you want to sound as a big aftermarket cooler expert. Next time, search more about the things you believe are facts, before putting them onto a forum and giving someone a very bad advice about hardware modifications.

I can give you a lot of examples like this if you like - 4870 water cooled reaching 126 C on vrms with "crappy little heatsinks on them".
I also have a thread on these forums, where I got 95 C VRM in ATi tool, after just a couple of seconds, with the S1 with 2X120 fans onto it and some of those fantastic little heatsinks,on a 4870.
