    Since recieving my 4890 the fan has been a little rattly. The rattle dissapears when the fan is running at 50percent. But while I am not gaming and just doing everyday stuff that does not require the fan to be going at 50percent I either have to put up with the rattle or crank the fan up to 50 percent. ( I hate RMA turnaround time so I havnt bothered doing it )

    I just ordered a http://www.scorptec.com.au/computer/34382-ac-tt

    My question is this should I try the VRM cooling that comes inside this or should I take the standard cooler appart and put on the ram/vrm (block). I cannot seem to find any VRM coolers available here in Australia as yet, I see Thermalright and Zalman have a solution but cant see it being available here in Oz for a while.

    I also wonder if anybody has attempted to make their own out of an old heatsink which I may end up doing.

    The 4890 heatsink comes appart and the GPU cooler can be seperated from the rest so I guess in theory I could just fit my accelero over the top?

    thats what i did, but i have no idea if yours will fit. as i said, mines a non-reference design, so it wont be the same as yours.

    I guess there is only one way to find out. I will take it apart and see if it fits.also thinking about cutting an old P4 478 heatsink down to size and fitting that.

    If the 4890 reference cooler is the same as 4870 (at least in dimensions), then the TT fits it okay. This is what I did after trying the TT's own vrm coolers (fried the card) and a Zalman heatsink, which had to be cut and still didn't cool properly.

    So yes, it fits and it's the only good solution for air cooling.

    Yes I definatley do not want a dead card on my hands. I am going to mess around and try to mod an old 478 heatsink into a VRM cooler it may work or may not
