My video card's HSF/RAMsink/retainer clip pics!

[Über~PhLuBB]

Finally got my camera, so here's some pics!

This is the finished product in in my puter.

This one shows my loss of 2 PCI slots, and how I allow air to escape behind the card's HSF.

This shows the old clip I had on the card, alongside the new clip.

The bent clip looks much better, and is quite a bit stronger, but unfortunately, it wouldn't fit on my new motherboard. The AGP slot is farther up, and I had to manufacture a new clip, as well as cut 5mm off one of the bolts.

The clip is held on by 2 bolts going through the card, and it held off the components on the back of the card by a small riser I made (shown below).

There are 2 extra holes on the new clip because I screwed up the distance between the holes, and had to re-drill holes on the other end of the retainer.

Another pic of the new clip.

This one shows the riser between the clip and the card.

I can't show it, that would require me to disassemble the card again, which is a pin in the ass. But basically, it's a square piece of filed aluminum (the same material as is the clip), with the corners filed off to fit between components on the back of the card, and keep the retention clip off those components.

This way, the entire force of the bolts is focused directly behind the center of the GPU (And no, it's not like I cranked it down 'till the card splintered, it's hand tightened, then tightened another 1/2 turn with pliers on each bolt.)

Heres a clear one of the heatsink/fan and my MASSIVE RAMsinks on my Visiontek GeForce2 Ultra. The heatsink was a giant 6" x8" heatsink my friend was cutting. I nabbed some of his waste, and fashioned what you see. The RAMsinks are an old Foxconn Celeron processor that came in my Sony VAIO. And that's a Delta 60mm fan on that monster HSF!

I attached the RAMsinks by putting ASII over all but one corner on each RAM chip. I put epoxy into that corner. The pattern the epoxy follows is bottom left of the first chip, top right of the second chip, bottom left of the third, top right of the 4th. This keeps the holding pressure the same all the way accross.

And I know, you can't get epoxy squished down as thin as you can get ASII, so I put on more ASII. This makes the ASII about 3 times thicker than it would be on a CPU, but it's still alot more effective than Visiontek's crappy glue (The stuff they put on is literally 1mm thick, and doesn't cover half the chip's surface!).

Why such big heatsinks? Easy, I couldn't get over 510MHz on the memory before. Clad in these cooling marvels, the card runs at 280/535.

You can see some tape on this one (And better on the riser pic above). I have tape on 2 of the 4 sides of the HSF to focus air towards the RAMsinks. There is still 10mm at the base of the HSF where air can escape, but most of the air is diverted towards the RAMsinks.

This pic also shows the small bit I had to file off the RAMsink fins to fit the contour of the GPU's HSF (The fan on top ot the heatsink is 2mm wider than the heatsink, so to keep the RAMsinks covering the whole top surface of each chip, I filed the fins down).

This mod isn't the prettiest, but it sure took alot of filing. Both the retainers and the retainer riser were made from a strip of 3" wide 3' long 1/8" thick aluminum.

Both the retainers, the riser, the HSF, and the RAMsinks were all lapped starting with a file (to take off the anodization), then 220 grit (to remove the file's gouges), then 600 grit wet/dry (to remove the 220's scratches), then 1000 grit wet/dry (to make it baby smooth).

Nice job man.

Looks like the both of us are in need of a GFD

nice job, i really need a camera, my fop32 takes up 3 pci slots

Heh... I pulled the case off my CPU the week I got the dang thing, hoping to buy a GFD, and I just never got around to it. :rolleyes:

Check out the one I bought for $48:

http://www.half.com/cat/buy/prod.cgi?cpid=1000036496&domain_id=11&meta_id=6

It's only 640 x 480, but it has 4MB of memory, which is twice the ammount virtually all other similar cameras have.

I have my visiontek ultra going at 275/528 with the original heatsinks/fan on there. but, i have two System Exhaust blowers, one on each side of the vid card, pulling the heat off of them, and putting it right out of the case :)

Heres what one looks like. Not the same brand, but this is just a reference.

If only Dell system boards would let me see my temperatures on my geforce2 ultra. anyone know of any programs that can tell the temp that I dont know about?

I want to push it further, but i'm waiting until i get another board first.

Right now, it has no problems, what so ever.... lucky me :)
