|72 c is way too hot. I was running into similair problems in WoW a few weeks ago, until I noticed the spikes in temperature that I would get while playing the game. All I did was took a fan off an old cpu cooler I had laying in the closet and bolted it on. It's now running at about 43 c at all times. Of course, it better, the damn thing sounds like a jet engine and runs at 6400 rpm.|
Get yourself a new fan and heatsink dude, and some artic silver compound. You might want to get a kit that allows you to adjust the rpm of the fan with a knob.
Your power supply may not be able to handle all your hardware. If you have more than one hard drive plugged in, unplug the one you don't need. Unplug all the devices you don't need while playing wow.
If your running dual channel ram, make sure that it's seeded in the right slots, check your mother board manual.
Turn off anti-aliasing and vertical sync in your graphics card settings and the wow video settings. Mess around with the graphics aperature size in the bios settings.
I know it's not your ping dude, I play on euro servers from california at a consistent 250-300 ping.
One other thing: in your
"World of Warcraft\WTF" folder, is a file named "Config.wtf". Open it with wordpad and try changing the
SET gxApi "opengl"
SET gxApi "direct3d"
or vise versa.
If that line isn't there, add it. And make sure you have the latest directx installed from the microsoft website.
