For awhile I've been thinking of getting the ZALMAN VF900 for my ATI 1900xtx, however I haven't been able to justify the money for the fan, there is always something else that comes before it. Today I was bored with nothing to do, I decided to do some tweaking to the 1900xtx, to see if it would make any difference in temp. They say a picture says 1000 words, here are the pics below of what I did to the 1900xtx. With the stock cooler Fan Operating @50% under 48C, and 100% at over 55C Temp was: Idle: 47C Load: 3Dmark06@68C, Playing NFS Carbon@70C After the mods with the same fan speeds as above: Idle: 45C Load: 3Dmark06@63C, Playing NFS Carbon@65C Well......overall not spectacular results, but a difference of 5C it's quite impressive, specially something that didn't cost me anything, and it only took 30 minutes to put together What do you guys think???
