I'm facing a lil problem with my vga temp, I lives in Cairo, Egypt...and the temp. here guys is killing the human begins, so i feel that the performance of my vga is not that perfect coz of the heat....
my PC components:
Motherboard: Gigabyte 890FXA - UD5
Processor: AMD Phenom II - X6 - 3.0GHZ - 9MB Cache (with Cooler Master Hyper 212 EVO Fan)
RAM: 4x (2 GB) 1333 pass
VGA:ATI Radeon HD 5770 (1GB - GDDR5)
Sound Card Genius Live 5.1
3 H.D.D All western (350,500,1000)G.B.
2 DVD R-W (Sony-Samsung)
2 regular fans (1 to pull the hot air out of the CPU unit & 1 to Supply the CPU unit with the ambient air)
With power supply Antec 450 watt
The card gets its cooling air from inside the case, so you need to reduce the case temperature as much as possible. I assume from your post that the room has not got air conditioning? Either way, the best you can manage is the same temperature inside the case as the room. But that means getting all the heat given off by the CPU out of the case, which means either water-cooling or more case fans. A larger case helps air circulate, as does tidying up the cables inside, but first, get more case fans.
