Good review Mike.
It's a nice compact GPU cooler (kind of reminds me of the Zalman VNF100 cooler, even the shape of the fins is very similar...). They should reuse that same design, add a couple of heatpipes and another fan (maybe team up with a quality fan maker !), and extend the heatsink. That would clearly be a winner. It's nice to see someone is trying.

Nice review. I start to wonder whether there are no proper VRM heatsinks available on the market? It can't be too difficult slapping a 2cm aluminium construct with a thermal pad onto these.

There are a few VRM products out there that I know of.
Thermalright make a couple of very good VRM coolers for ATI HD4870/4890 cards.
VRM-R1
The also have some bits and pieces for Nvidia cards, although they look nothing like as effective. Maybe they don’t need to be for some reason.

Zalman also do a couple of items:
Zalman for HD4870 / HD4890
Zalman for HD3850 / HD4850

Or you can roll your own like I did (rather expensively!)

Enzotech Northbridge heatsink adapted to fit the HIS chip and RAM sinks cut to fit under the Akasa Cooler. The actual VRMs have Enzotech VRM heatsinks, that I think are really intended to be used on a motherboard. I’ve not done very extended Furmark runs but it’s stable running folding@home. At low fan speeds it does all get very hot, the VRMs becoming to hot to touch! There is no VRM temp reported on this GTX260 so I don’t know the actual temps, the reported “PCBâ€

Why bother? Get an Accelero L2 Pro, which comes with VRM heatsinks, a very, very good fan (can't hear it above my 4V-Slipstream-1200's) and retails for $16-20.
This Zalman looks extremely weak in comparison.

Good review as usual, Mike.

Any chance you guys could take a look at Thermalright's HR03 and T-Rad?
