I recently purchased a Zalman VF1000 cooler for my Sapphire X1950 pro and I have to say, it works like a dream, the GPU core has gone from 60 degrees at idle (with stock cooler) to 40 at idle. The problem however is with the blue ramsinks that come with the cooler, I have applied them exactly how it said in the manual, taking extra care to ensure they are applied securly and covering the VRAM nicely, however, the temperature of the VRAM has gone from averaging 40 degrees (stock cooler) to 80 degrees at idle, while playing Call of Duty 4 yesterday I minimized the game to find that the VRAM was 124 degrees! I dont have a very good PSU (only 250W its the stock one that came with my PC 4 years ago) and I am getting a new one ASAP. Surely that can't effect the heat of the VRAM particularly as it is essentially only cooled by the blue ramsinks. Anybody have any suggestions or ideas why the temperature has gone up so high? If you need anymore info just tell me and I'll post it up. I'm quite new to all this stuff but I'm eager to learn.
