Thermalright Readying Series of VRM Coolers for Radeon HD 4870, HD 4890
Thermalright is readying a couple of VRM area coolers for the AMD reference design ATI Radeon HD 4870 and Radeon HD 4890 graphics accelerators. The Thermalright VRM-R1 and VRM-R2 work in conjunction with the company's T-Rad series GPU coolers, and strive to provide a high level of cooling that allows better overclocking.
The cooler consists of an a heatsink that covers the VRM area of the accelerator. From this heatsink arise two nickel-plated copper heatpipes that convey heat to a small but dense aluminum fin block. This block is big enough to let you latch an 80 mm fan onto it for active cooling. Both VRM-R1 and VRM-R2 are essentially similar in size and shape of the components, except for that the two differ in the positioning of the aluminum fin block. For VRM-R1, the block propagates perpendicular to the plane of the motherboard, while that of the VRM-R2 propagates parallel to the plane. Both coolers weigh 160 g. They are compatible with most Thermalright GPU coolers, namely HR-03 Rev.A, HR-03 GT, HR-03 GT V2, T-Rad2, and T-Rad2 GTX. They will hit stores very soon.

i'll need pics of the second one before i can tell how it'll work in a case.
EDIT: My bad... just now noticed that it says 80mm... :D Still, this will be an awesome solution for cards that don't have enough cooling. Or even coupled with a GPU cooler.
I've ran at least two cards since then and choose multi-gpu's with modest oc's and stock coolers over a single aftermarket cooled card. If aftermarket, it's gotta be multi-gpu friendly both in design and cost. Maybe things will be different with a DX 11 flagship, but for now, gotta have two cards..
When I changed to the Accelero S1 and used its VRM heatsink, which had the VRM temps hitting 120'C. I had to mod it to use 2 120mm high flow fans to get temps down to 75'C under load.
VRMs produce an astonishing amount of heat, and start to deteriorate at 120'C.
That said, even in my Lian Li that isnt the best airflow with stock air cooled 4870's my temps never went above 105'C on the VRM's and even thats too much.
Water temps are much better than air but this doesnt seem such a bad idea to be honest, if your into some serious clocks on your cards. :toast:
Why Thermalright doesn't make a single cooler solution that covers the ram, core and vrms all as one piece, like the stock cooler but more efficient. Those little ram sinks don't do anything. They are back pedaling now because they forgot something. So with the HR03 and one of those VRM coolers, I think my PCIexpress slot is going to break off the motherboard.
