Literally "hacked" this heat sink. ;) HD4890 + Accelero

post #1 of 14
Thread Starter 
Hello, all. How did I do? smile.gif

Pictured: Sapphire HD4890 with Arctic Cooling Accelero. I had to cut the heat sink to make it fit. RAM heat sinks attached with Arctic Alumina permanent adhesive. Used Shin Etsu thermal compound for the GPU sink. 120mm fan attached, blows toward card.

HD-4890 Enterprise? ~Isometric view.

Fan attached. Note the creepy perspective on my hand.

Anchors. One of them uses double-sided tape because the fan was in the way. LoL yes, it's very effective and safe when used properly. There's a lot of it in this project, holding the fan to the heat sink very securely. I can lift the whole unit by holding the fan.

Finished!

SCROLL DOWN TO POST 8 FOR TEMPERATURES.

Whoa! Freaking Cool!

What are your temps now???

I have the SAME two cards (Sapphire Vapor-X 4890)

What were your temps before? I can get up to 90°C on my top card; so I can understand why you put in a new heatsink...And I thought Vapor-X had the best cooling technology.... confused.gif

OKAY, I have temps.
0116012122.png
This one is shortly after installing the graphics card.

downsized950117011702.jpg
This one is after running for FIFTEEN HOURS.

This baby was hitting max temps in excess of 70 DEGREES F.! As you can see in the pic, it is now maxing at 55*C, quite an achievement for so frail and inexpensive a heat sink. This is a max from TEN CONSECUTIVE HOURS OF USE.

Kudos to the Arctic Cooling for the Accelero's efficacy! As you know, this heat sink was not meant to fit the HD4890, ESPECIALLY the Sapphire Vapor-X version. Luckily, the screw holes lined up, and I had four longer screws (from disassembling the OEM cooler) that matched the threading on the OEM cooler. Cautiously balancing the tightness of all screws, I fastened the device and checked with a bright light to see if there were any contact gaps between the block and the GPU. Success.

The OEM cooler was USELESS. It really does do nicely as a hefty paperweight, though.
