ASUS Ready with HD 6770 DirectCu Silent Graphics Card

ASUS is ready with a new silent (passive-cooled) graphics card based on the AMD Radeon HD 6770 graphics processor, the ASUS HD 6770 DirectCu Silent. ASUS designed a new passive GPU cooler from ground up, which makes use of heat pipe direct-touch design, which ASUS refers to as DirectCu (direct copper). The cooler is essentially a large aluminum fin heatsink that uses four nickel-plated copper heat pipes, conveying heat to a large aluminum fin stack, that is longer than the card's PCB itself.

Based on the 40 nm "Juniper" silicon, the HD 6770 is a rebrand of the HD 5770, it packs 800 stream processors, and a 128-bit wide GDDR5 memory interface to hold 1 GB of memory. The core is clocked at 850 MHz, and memory at 1200 MHz (4.80 GHz effective). The card draws power from one 6-pin PCI-E power connector. It uses high-grade "Super Alloy" VRM components, that are efficient, and don't lose energy to high-pitched noise on load. The card's display outputs include one each of DVI, D-Sub, and HDMI 1.4a. There's no word on the pricing and availability.

If only that cooler had mounts for an optional fan. That cooler with a low speed fan would do great.

Mighty beefy cooler for an 2 generations old mid-range GPU.

Use a cheap slot fan if the card gets too hot.

If you look at the passive 5770 by gigabyte, the cooler is even larger.

Well who need mounts? I find cable ties work great... when done this way.
8 cable-ties, along with some small nylon washers, and sticky back foam like say the thin sound insulation backing. Now I don't loop them, I thread a washer on the cable-tie; then slip that though the fin(s) in 4 places for the fan size I've chosen. Cut 4 little foam insulator pads and affix them over each screw holes on the fan to space and isolate the fan and fins. Position the fan over the 4 tie’s coming through the fins and again use the washers and ratchet block from the 4 other tie’s to tighten the fan in place. Finally trim all the ends and you have very clean, tight, mounting that doesn’t ruin the heat sink. Been doing it like that for years.

Without the cover, it reminds me of the thermalright HR-03.

Yeah. Unless my eyes betray me, I think it has PWM.

Asus is getting really stupid with these cooler designs. I could sort-of understand going triple-slot on the enthusiast GPUs, but this is a 6770.

Who said it's triple slot? Doesn't look it to me - look at the size of the PCI bracket and then the cooler itself (in the first pic).

First GPU cooler that can be seen from space?

It really doesn't make sense, no only does it hinder performance, it costs them money to add that.

They could charge the same amount for ones without it. More profit!?

Confusing to say the least.

D-Sub really :slap: who the fuck uses D-Sub these days
would have been an interesting card if it had 1 each DVI, HDMI, mDP

and the heatsink is nearly twice the length of the actual card

i'm using two VGA monitors as secondary/tertiary. that said, i use DVI to VGA adaptors, and REALLY prefer DVI as the default port.

actually it does, you can see there's a space between heatsink and the bracket..
