Yeah..that one...hehe.

Load temps went up to 57c max while I was running Overdrive.

Those blue ramsinks came with the zalman vf900. I put them on the power supply components that were covered by the stock heatsink. I bought those gold ramsinks (which I put on the memory chips) at All IT. It comes in an 8 piece pack for RM25.

The zalman works fine. It is pricey but the quality is superb, fitment is simple and great, and you hardly hear it. I heard you can get Accelero S1s for cheaper and they do just as good a job, if not better. Either way you choose, you will be satisfied.

PS: I heard that ATI is coming out with factory overclocked 4850s: http://www.tgdaily.com/content/view/38077/135/. I'm waiting to see if my "home overclocked" 4850 can match its performance..
