thanks for replying so soon.. its non x just r9 280. i have a midi tower with one 12cm on the back top of the case and one 12cm in front. i can add a 14cm, which i will, at the side of the case. the thing is that i bought a cooler for my cpu bcs its an 8320 and the stock can't handle even browsing, jk, and the fan is facing the back of the gpu. do you think thats it matters? although i change it 2 days ago and th temps were the same before. (sorry for my english)
