Removing NB/SB integrated heat sink;
2 options, remove NB sink from IHS or remove IHS while still attached to sink. Not sure what is noted as easiest cause I did both pn several mobos and it's hit or miss which goes smoother. The obvious advantage of the removal of actual IHS off the chipset die is that you get the best of contack to the replaced cooler, wether it be OEM or aftermarket, any drop of temp is a "+".
Prepare; remove all plastic retention clips from back. Only one will stay in loose but at least free it from back (under mosfet cooler) Free SB section 1st as described below. make sure all the rest is free to allow the next step to go smoother.
Start w/ the method I describes much earlier for attempting to only remove heat sink, leaving IHS attached to chipset die. If for any reason it feels like its requiring too much effort, move on to carefully working at loosening and removing IHS from chipset die w/ heat sink still attached. (see below)
To help, I used a moderate heat soldering iron to heat my sink to just hot to the touch. Periodaccly, I dripped 99.7% alcohal into jiont where sink meets the IHS and IHS meets the die plate. for the most part, heat will soften the OEM thermal cement and allow alcohal to seap inbetween the IHS and sink 1st and you can gently work w/ a slotted screw driver of about 1/4" wide to sort of twist from base of die plate (the green plastic part) and under bottom of sink (the copper plate). Try from different sides to find the weakest and go from there. Once you see so much as any opening, hold and drop some alcohal into it and continue.
If the 1st method feels like it's taking too long then move to the IHS removal.
If you look down the mobo from front edge (RAM and SATA side), you will find a small indention at the fron fase of IHS. Usually this is often gooped over w/ cement so use a fine steel pick (size of tooth pick, I use my dental tools) to poke in the alcohal soaked area allowing the rest to fall in the opening. as it opens, try to work w/ mobo inverted upside down so alcohal loosens the IHS from the die as it is lithtly cemented from underneeth as well as lightly glued from edges where the IHS meets the plastic die plate (green part). now gently twist the entire heat sink as a unit (from SB and mosfet) over NB untill it begins to feel loose and wiggly. Add a few more drops of alcohal if need be to aid.
TIPS; If you are concerned of oops's, mask around chipset w/ painters tape and paper to reduce scratching by slip of tools.
To remove cemant and clean. I like to use Barrymans B-12 non residue brake cleaner in a spray to quickly soften and wipe away with cotton swab or ball. It drys fast so have plenty of wipes to remove desolved glue fast, repeat till gone, and finish final cleaning w/ above alcohal (99.7% as used for A/V head cleaning or tuner cleaner). This stuff is flamable so use outdoors and keep all electrical circuts OFF close to the work area. the high strength alcohal can be had at many electronis stores and even Frys has it in both open can or sray. Brake cleaner can be found many places such as Target, Wall-Mart and just about any automotive supply store.
Didn't mean to make this long but didn't wanna' miss anything either, but if you have any questions before going at it, PM me and or post reply.
And of corse as always, anything we do like this to our motherboards is all at our own risk so study carefully. Keep all removed parts in case of RMA, replace w/ any suitable thermal cement to return for whatever reason. They (ASUS) never hassled me yet.
