I have here a PCI video card GFMX420PCI, which translates to an NVIDIA GeForce MX420 64MB PCI video card. I was using it on my ASUS CUR-DLS board in place of the onboard 4MB ATI Rage.
It started to get flaky, so I replaced the 4 Canicon 6.3V 1000uf with Sanyo WGs.
Tried some full-screen youtube video, worked great. Went to swap it out as I was going to test another card, and WOW it was hot. Probably 80C. It has the little 2-pin connector, so I could attach a 40mm fan. At present it's passive cooled heatsink.
Why so much heat? Should I expect a PCI card to get hotter than an AGP card?
The onboard rage cards don't even have a heatsink. Obviously this card fried the Canicons. Two of them had ESR approaching 1.00. Card is not burnt in any way.
So is the card defective and am I wasting time adding a fan?
Or are video cards expected to have short, hot nasty lifespans? Or should I look to some component that is adding resistance, and hence heat to the circuit? It does have one large MOSFET Niko L1084S DNA1327D84 and 2 Toroidal Inductors, but no parts
