Zalman releases VRM heatsink for Radeon HD 4890 / 4870
Finally someone releases a heatsink for cooling the VRM section of the HD 4890 and 4870, (albeit a little too late for me) for reference-design PCB though.
Zalman ZM-RHS90
Apparently Thermalright is also about to release a VRM heatsink soon.

An user from other forum said it fit with Accelero S1: http://www.overclock.net/ati/526969-zal ... ost6506484
BTW here's the Thermalright VRM heatsink:

The ZM-RHS90 is 23mm tall

The Accelero S1 rev2 only has 16.5mm of clearance in the area where the heatsink would go:

I'm not sure if the Accelero's fins would fit between the fins of the Zalman heatsink, and of course there is the heatpipe in that area which Arctic Cooling state has only 23.3mm of clearance. That's not a lot of tolerance!
I think the dude on overclock.net was talking about the compatibility of the 4890 baseplate and the Accelero, as opposed to the Zalman and the Accelero.
However, I may order one of these Zalmans on a chance that it will fit with the Accelero that I currently have fitted. Will only be £8 or so delivered.
