I'll try to explain it the best i can so bare with me. I just bought a connect 3d hd4850 from a good friend of mine. He said that with the reference cooler the card will get a little hot while gaming but i didn't think nothing about it. He said i need to buy a good aftermarket cooler if i want decent temps. All was just like he said, with the reference cooler the temps exceeded 100 degrees celsius with the fan at 80%, and was very very loud also. I then bought a akasa neo vortex cooler and i had that friend mount it up for me. The problem now is that the temps didn't go down at all...i still get over 100 degrees regularly while playing. It isn't loud anymore but it doesnt cool the card right, so i was wondering what the problem was. Can it be it isnt mounted right? One thing to note: just under the graphic card i have a sound card installed and there is very litttle space bettween the two. Can that impact my cooling that much?? I dont have another free pci slot to move the sound card. The case has only one side fan 12cm at 1200rpm.
