nForce4 chipset woes (prz help srsly)
So the other day my computer was making horrible noises. I open it up and eventually figure out that it's the fan over my mobo's nforce4 chipset (not the cpu, it's a mobo chipset) - it's turning awkwardly and slowly and making loud weird noises. So I resolve to replace it. One trip to CompUSA later, I have a 'Blue Ice' or whatever chipset fan and I go to replace the current heatsink & fan combo. Turns out the old one is held on by two plastic bolts with springs on in the lower left and upper right corners, distanced a tiny bit from the square heatsink enclosure - I can lift up the heatsink about a half centimeter and I can push the plastic bits into the board that far, but can't remove the things for the life of me. After dicking with that for an hour (removing the metal screws on the heatsink's face et al just to find out that I can remove the heatsink & fan's faceplate and fan itself but still not the heatsink, which is still attached by those two plastic things), I get pissed, get emily's Channel-Lock wirecutters, and just snap the things off. One of them falls out of the mobo completely, the other I can't get back through the hole, but whatever.
So I finally remove the old heatsink to find that this is not your normal smooth metal cover mobo chipset, it in fact looks a lot like a CPU - exposed circuit board with a lil chip in the middle, and thermal paste all around. I clean all the paste off with rubbing alcohol and go to put on the new heatsink & fan, but it was really designed for normal chipsets, so the bottom of the heatsink has a large square of self-adhesive tape on it. I cut a lil square hole in the middle for the cpu, put some thicker double-sided tape around it, and pressed it onto the chipset and hooked everything up. Everything seemed to be gravy. Last night I set a bunch of downloads and went to sleep.
This morning, I come back to find the pc restarted. I log in and start the downloads again and the computer locked up when clicked on the start menu - It seems like something is overheating. Last night I had the thing running for at least 6 hours with no problem, but I did have the side of the case off during that time. However, my case has good ventilation and it shouldn't be getting that much hotter with the side on. After giving the computer a 'rest' of about 10 minutes this morning, I turned it back on and it's been good for at least 15 minutes now with no complaints, but then again I'm not telling it to do anything aside from run a web browser.
* Is it possible to get a heatsink for a chipset that has that gay two plastic pin w/ springs fastener?
* How can I track the heat of my mobo chipset?
* Could my problem just be because I didn't re-apply thermal paste?
* How can I make sure my pc doesn't melt while I'm using it ;<
* Is there a way to make the PC turn off if the chipset overheats? I know there's a way to do it for the CPU in the BIOS.
* Could Azureus or eMule be partially responsible for the strange behavior at all?
* What is your interpretation of the speedfan numbers (below)?
