Removing the Intel IHS has always been a great way to drop temperatures as much as ~10-12C sometimes providing additional overclocking headroom; sometimes permitting the lower voltages for identical CPU core speeds...

The Intel LGA775 mounting system has been particulary difficult to deal with when it comes to naked CPUs.....until now. The solution is so simple it should almost be criminal.

The problem with removing the Intel IHS is that the newly exposed core sits lower than the edges of the LGA775 bracket cover piece making it impossible to make the much needed CPU <-> heatsink/waterblock/evaporator head contact without completing time consuming, permantently altering modifications to your cooling solution. Not any more!

***Note: Be sure to protect your pins when doing this! A slip of your hands could quickly ruin your expensive motherboard!

Open the LGA775 socket on the motherboard that you will be "modding." Then, using a slight twisting force, push in on one side of the bracket while pulling out slighting on the other side. You should find that the hinge on one side easily moves past the retaining slip which allows you to completely remove the cover. You easily later reverse this modification by re-installing the cover just as you removed it.










Here's what we're left with:







Mounting is now possible. The LGA775 cover braket is not really need to properly secure the CPU in place before mounting your cooling solution. Torquing down on the mounting bolts will push the CPU into the socket well enough to make complete contact as required. Be careful now that you have an exposed, naked core. Too much pressure can result in damage to your processor.

Note that mounting the CPU without the MB being held horizontal may be difficult/impossible now that there is nothing to securely locate the CPU in place while installing your cooling solution.

-> Final thought: Although I do not have a new AMD LGA1207 MB to test this on I would be very surprised if this same concept could not also be applied to those sockets....
