    Default Changing thermalpaste on X48 DS4

    I have this board for over a year now and i want better cooling on the northbridge. Is it wise to change the thermalpaste on it? Will i need new thermalpads for the MOSFETS? Anything else?

    Thanks in advance,


    Filip

    I always do. Be careful as it is a bare silicon chip under there.

    I would leave the pads on the mosfets and the SB, that will be fine. Just redo the NB paste

    Im not doing the SB as that isnt connected to the other two with a pipe. I'll try to do it tomorow. It shouldn't be more dangerous than redoing a graphics card thats also bare chip.

    Yeap, bout the same as that. Just wanted to mention that in case you did not know.

    Good luck, and post back if you have anymore questions about it all. I do suggest you use NON Conductive paste such as TX-2. MX-2, or Arctic Céramique

    I've done it twice on my Gigabyte 9800GTX, used MX2, the 2nd time i evened out the base of the cooler a bit and compared to stock i lowered the temp by like 10 deg celsious in best case scenario.

    What worries me is that i've read horror stories about the standard thermalpaste turning into superglue (wha?!) and sometimes the NB coming out with the Heatsink?! Don't really think thats possible my self.

    I think that used to happen more in the past then now, but yes I have heard of that too.

    The paste Gigabyte uses is not that hard though, you will be fine. If you worry, heat up the board from the back with a hair dryer and that should loosen it up a little bit

    If i managed to open the graphics card this shouldnt be a problem. Same maker, probably same paste aswell :D

    Ya, it isn't usually on too tight. Give it a wiggle then a nudge up and it will come off.

    And yeap, it likely is the same thermal paste too so you know what to expect. That silver pasty type, that is of course way to thick :)

    On my board the NB TIM was more of a wax based material. It was easy to remove. I used some TIM clean on the actual chip and had to scrape the TIM off the NB cooler first as it was thickest there.

    As always, use plastic to scrape TIM from a HS if needed as metal may gouge the surface and lower the cooling efficiency.

    The heatsink was easy to remove though> I ran the PC for ~ 15 minutes with Prime Large FFT going out of the case, then powered off and quicklt removed the NB screws. Replacing it with MX-2 went well. I used the spreading method as with all bare chips. Because there's no metal heat spreader on them the whole bare core needs coverage.

    Likely the MOSFET and SB coolers are using some sort of pad rather than TIM. On the UD3P the pads remained well stuck to the heatsink but just lifted off the components as the adhesive is only on one side. The sinks went back on with no problems at all.

    All right, tomorow im taking the PC appart just for this, it better work! I use 70 or 90% Alchocol to clean thermal paste, it cleans it pretty good.

    What made me do this is that i constantly see voltages for 4GB of RAM for the NB on like +0.2V and higher. Well i don't have any problems till 3.8GHz even on +0.125V, but on higher speeds the NB heatsink heats up pretty much and i can only hold a finger on it for about 7 sec really, so this wil surely help on higher FSB aswell.
