i'm not making good enough contact with my dtr. Is there a way i can make this xp120 touch it better? It'd be awesome if this was also reversible, so i could use a lidded a64 or a lidless a64.

What should i sand on this bracket? Should i do anything to the blackplate?

and does it really make a difference?

Well, it should make good CONTACT, if it isnt there is something wrong

Try lapping your heatsink, I lapped mine to a 2000 grit finish and it was perfectly flat and mated very nicely, but the pressure wasnt superb

So, I sanded down the top plate thing like 3-4mm, which gave and ample ammount of pressure to the bare core, like before you could wiggle it, or nudge it, now its ON THERE really solid!

Give either a try for, or both for max results good luck

I dont know if the DTR is the same as a one without the IHS.
I grinded the "top" plate, those "legs" and below the screws.
I grinded away half of it before i got good contact.

You can also put a shim under the springs on the xp 120. The springs are attached to the base with a screw. You take it apart and add a shim under the springs.

The 'wings' on the base run into the plastic which is one of the things that screw up the contact. Place it in and look closely; you will see what I mean. As for lapping, since the one I got was VERY concave, lap it starting w/ 400 grit, and if really bad, then switch to 220 SiCarb, then work back up to at least 1000 grit. Find a THICK, FLAT piece of glass to put the sandpaper on, and WET sand it (a drop of dish detergent does wonders) clean paper and xp-120 often.

Yet another pic to take and post this weekend. I think I will just make a 'stuff' thread tomorrow. If in REAL hurry, look for my descriptions around here somewhere.....

One last thing, heatpipes face I/O area....

My heatpipes face towards ram.
And mine was very concave also.
