copper shim mod for P79 Quad core

I am thinking about AS5 and copper mods. Since the OEM HS design does not cover the entire cores of the quad with copper and I want them covered by copper not just the aluminum overlap.

I am looking to get a 30mmx30mmx0.8mm for the cpu and then for the NB a 24mmx24mmx2mm to make up for the gap that is already there? the uestion for anyone already doing a mod on the NB of the P78/P79 is what size did they use, 1mm or 1.2mm

 

I just found some copper sheeting in the roofing section of home depot, don't know what thickness. I would just double up for the NB and video memory chips.
Or you can find smaller pieces of copper tubing connectors in plumbing, then cut and flatten.

 

I am tempted but figure proper shims is better. I have no immediate need as the ICD is doing well enough for now..............

 

For some of the best items for modding things, or finding just all around odd stuff, McMaster Carr is one of the biggest outfits I have found.

Looking for copper shim stock? Here is the McMaster Carr link.

Thanks for the link. If we had alot of members interested it might be worth getting one of the larger sheets and going too town..............

 

ok recieved 10 x 20mmx20mmx0.55mm I use one each on the two cpu cores and 2 packed together for the NB. NB runs cooler about 8 c under load. Core 0 is about the same at 3.2 GHz but core 3 is only 5C hotter instead of 8-9c hotter than core 0. So the mod in the end is worth it.

PS: did this all and still using ICD.....................

 

Awesome TANWare!

dude, you should have shot some pictures and included them in this thread

 

ICD is much tougher than normal paste to do a "thin" spread. I took a small drop and ground in a circular motion two pieces to make a sandwiched stack. by the time I was done it was stuck together as one piece.

The two shims on the cores then were again moved in a slight circular motion till they also were essentially glued to the cores by the thin remaining TIM between the cores and shims. The same then for the stacked shims to attach it to the NB.

then three small drops on the stack over the nb and one each on a shim over the each core. without screwing the HS down slow small circular motion was used to make the HS attach itself to the shims with a thin ICD film.

Then I tightened the HS down and done!!!!!!!!!!!!!!!!!!!!!!!!!

New Avatar, slightly lowered temps overall..................

Edit; Circular motions was used to bond with a thin ICD film throughout. You have to do this very gently with very slight preasure and "TAKE YOUR TIME!!!!!!!!!!!"

Edit 2 ; do this method at your own risk too! ICD is extremely abrasive and easily can damage components, let alone issues with copper conductivity!!!!!!!!!
