GPU Fan Not Working: Dell Inspiron E1705

[METALLlC BLUE]

The GPU isn't turning on at any point.

I purchased an Antec Fan Cooler just to be safe since I felt the machine was overheating. It wasn't pricey and is portable via the USB. It keeps the GPU temp around 55 C at idle. Without it the GPU goes to 65C idle. I haven't pushed it with games so I don't know how high it should go. My CPU runs around 30 C at idle and around 55-60 C when pushed to it's max.

I have the I8KfanGUI utility. I tried replacing the GPU fan after clearing out the dust and found no clog in the fan unit. The second fan I put in didn't work either. Any ideas?

Do you happen to know what video card is in your E1705? I have a E1705 that has a 7900gs and the GPU fan doesn't spin up until about 78C, unless forced with a fan profile in I8kfangui.

I believe it's the 256MB ATI MOBILITY RADEON® X1400. I've tried forcing it using the standard feature "Force Fan" in I8K, but only the CPU will run. It says the first and second fan are running at high speed (Around 4,200 RPM) but of course the GPU fan isn't actually running.

65C is a little high but not dangerous. Why don't you try running a 3d benchmark like 3dmark06 while keeping an eye on temps and the fan. If it starts getting towards the 90C mark and the fan still hasn't kicked in then there is definitely a problem.
