I have a three year old Inspiron 9400 T7200 GeForce 7900GS, W7HP, and the GPU fan has stopped - the temp is around 60-70C for browsing/email streaming video, but anything more taxing and it starts to climb - the CPU also starts to get hot up to 90c plus and then the screen stutters and shutdown is the only way out.
I'm using I8kfanGUI for temps and it reports the temps OK, but if I manually turn the GPU fan on it says full on but gives an RPM of 1958 but the fan doesn't move.
Can I get a replacement fan.. is it the same fan as the CPU cooling fan? (I've seen these on ebay).
Is there anything else to try first? It looks like a bit of a pain replacing it according to the service manual, pretty much have to strip the whole thing down :-(
Are cooling mats any good as an interim measure?
