Sorry to be dumb, but the photos on your site dont make it very clear to me.

Have you removed the old pegs completely, then installed M5 screws up from the bottom of the board into the heatsinks? Does 10mm take it nicely into the GPU heatsink without having to remove the fin on the top?

yes you have to remove the pegs. The 10mm will fit nicely and no altering of the heatsinks will need to be done.

Thanks, thats sounds really easy.

Does this also mean the clamps / sinks are no longer fixed into the metal base plate?

Kurto2021 · « **Reply #63 on:** March 21, 2007, 10:24:00 AM »

the clamps are in the trash. That is very important. If you don't put them in the trash they will poke you in the foot if you step on them.

Yeah, I got that bit from dokworms post, but he drilled the metal base and still screwed through it.

Are you just relying on the screws on the edge of the board to hold it down now?

originally I was going to set spacers in between the board and the metal casing then run a 12mm screw from there up through the heatsink. I couldn't seem to get the heatsink to secure properly that way and it resulted in 2 red lights. The GPU was overheating at that time. Since I never could get that method to work I pulled out the 10mm screws and then didn't go through the metal at all. If you look close at my pic of the metal you will see that I originally drilled out the holes for the GPU. I am assuming this should be good enough. Only time will tell.

Excellent, that sounds really easy.

Thanks for your explanation. I'll give this a go tonight (if I manage to get three tiny components I knocked of the board resoldered).

The only bit that wasn't easy.... getting M5 10mm screws

Two DIY superstores and this is about the only size they don't do.

Update:

Got it all together, working great so far. WAY more heat is transfered to the heatsinks, that's for sure. I am going to do the ducting mods and go from there. I have a few pics, but they SUCK.

I did a little persuading to the RF shielding to get it to fit with the small washers in. Seems to fit ok, if it doesnt fit in the chassis, I will just do some cutting - no big deal.

I used M5x10 (as I said before) and I BELIEVE the washers are #10 .050mm for the top and #10 .025mm on the bottom.

Lowes and Home Depot did not have them here but there was an Ace Hardware down the road that had one. I would try a smaller store similar to an Ace Hardware and see what you can find.

I'll send the wife out on an expedition tomorrow.

I managed to resolder the SMD's I had removed, so just waiting to put the sinks on now and fingers crossed.

Quick question, what is the thickness of the cork that you put under the board, and how did you attach it (glue?). Also, and this is only a question not trying to flame or anything, does putting that underneath the board just replicate the original X clamp pushing up, or because it has more surface area is this not a problem? Thanks.

dokworm · « **Reply #72 on:** March 21, 2007, 07:17:00 PM »

As long as the cork is the right height and the board lightly rests on it then it shouldn't be a problem. If the cork was too tall then it might cause issues.

Kurto2021 · « **Reply #73 on:** March 21, 2007, 07:40:00 PM »

I doubt the cork is really doing anything to be honest with you. It was part of the original plan with the spacers on each of the screws but that idea got scrapped. I would do it without the cork as I believe it doesn't even touch at this time.

cool thx for reply didn't know if cork was essential or not.
