Hey everyone, well i made a new thread because i know there is lots of ppl out there with 4890 that are interested in buying an aftermarket cooler so here is what i did with mine. Well today my Accelero arrived and i got my hands on it and i installed it and tested, here now some pictures and feedback for everyone. These are my temps before the Accelero Using the Stock Fan Notice that the fan at 40% its already noisy and at 50% you can really really hear it, its like a small jet engine . If you think how i tested this temps, well i used RivaTuner and also Everest, for Idle temps it was with the PC on not doing nothing for 30 mins in windows and for full load was 10 minutes of running Furmark at fullscreen. Stock Fan 40% Idle Temps 2700 RPM Aprox GPU 34 - 36c VRM 34 - 36c Mem 40 - 42C Stock Fan 50% Full Load Temps Furmark 3200 RPM GPU 74 - 76c VRM 95 - 99c Mem 76 - 78c It took me a bit of time to install the Accelero properly, as i said i kept the original red backplate to cover the memorys and the VRMs but i also added 5 of the ram sinks in a part where the red backplate does not cover, where originally the fan is places over. Here some pictures. Well after installing it, of course it was time to test it and see the results. As i said before the stock cooler was cooling the VGA greatly for me, but the main issue was the unbearable noise. AC Accelero Twin Turbo IDLE Temps ( Fan at 100% Spins at 1900 RPM ) and it makes less noise than the stock cooler at 30% it is absolotely quiet, really amazing ). GPU 30 - 33c VRM 32- 36c Mem 42 - 46C AC Accelero Twin Turbo FULL LOAD Temps GPU 62 - 66 VRM 80 - 84 Mem 68 - 72 I know the temps are almost the same, they havent improved much, it is good enough for me, more importantly the noise is almost null, i can barely hear the accelero spinning and i keep it at 100% always. If you guys get any questions please let me know.
