Heatsink problems

post #1 of 2
Thread Starter 
So I re seated the Northbridge heatspreader on my siggy's board. I used silver based Dynex thermal paste and covered the PCB around it with some masking tape to prevent the TIM from gooping onto the little capacitor/resistor things next to it. Sorry if I sound ignorant . So basically I have about 3/4 inch of masking tape surrounding the chip but the chip is bare. After putting on the heatsink again I noticed it was really loose....ignored and powered up, sure enough the temps were climbing and I shut it off. So I have two questions here:

1. Is there any way to secure the heat spreader the way it was before? I'm pretty sure the only reason it didn't wiggle from the factory was because the stock thermal paste was like glue - it took a plastic knife to scrape it off. Is my MB manufacturer cutting corners?

2. The "system" temp reading in my bios went up 10 degrees. I'm assuming this is the southbridge temperature. Why did this happen? I didn't touch the SB heat sink at all. It might have been wiggled was all I could think of, causing the TIM to break the bond with the chip underneath.

Any help would really be appreciated as I don't want to take this thing in or spend a lot of time removing the board to find out it didn't work.

bad thermal paste for 1 thing, dynex = best buy brand = bad like thier psus

anyways, put pressure on the heatsink with something heavy, say.. a 1LB weight, and leave your mobo horizontal, heat the paste up by running your pc, take the weight of, and see if it sticks, if its crappy paste itll be watery still and just slide around when u poke the heatsink

most of those heatspreaders have a locking mechanism to hold them to the mobo
