Is there any difference between the Arctic Accelero Xtreme III and the Xtreme 7970?

post #1 of 4

I've been looking to get an aftermarket gpu cooler and these are the most recommended. I was wondering what the difference is between the xtreme 3 and the xtreme 7970. They look like the same thing except the 7970 is branded for the 7970. Would there be compatibility issues if you installed the xtreme 3 on a 7970 pcb?


My card is this 7950 with a 7970 pcb http://www.newegg.com/Product/Product.aspx?Item=N82E16814202030

Looks like an amazing cooler, but it be considerably more expensive. I would have to buy a back plate and possibly some fans (I have 2 AP-15 that I could put on, but I would probably want slim fans to cut down on weight). Plus It would make it impossible to crossfire with in the future.

Xtreme 7970 has the copper shim built into the heatsink

Both products share similar accessory packages, with a couple of notable changes. The Accelero Extreme III comes with more memory heat sinks to accommodate a wider range of cards, while, for some reason, the Accelero Xtreme 7970 includes a mixed thermal adhesive that requires a catalyst. The fan power cable is designed to plug directly into the graphics card, so the driver software can alter the RPM in response to the thermal load.

A closer look at the 7970-specific cooling block makes the functional difference between these two products even more apparent. Radeon HD 7900-series cards require that the GPU contact area be raised from the rest of the cooler to clear a thick protective shim. The contact area is also turned 45 degrees to match the graphics processor's orientation on the PCB. Both Accelero Xtreme models come with thermal paste pre-applied.
