Graphics card with CPU heatsink?

Has anyone modded their graphics card with some old CPU heatsink? I was wondering about the mount holes :? . I'm sure something like an old P4 or AthlonXP retail heatsink would be sufficient to cool a low/mid range graphics card of today, such as a 7300GT?

Thanks.

Surely you must be joking.

I glued a K6-2 Heatsink on a 440MX, it stayed on for 3 years until it dropped of, i glued it back 6 months ago, it still works.

Got a picture? what about the thermal paste/pad issue? did the glue substitute? :o

I stuck some generic thermal paste onto the gpu, then I mixed up some Araldyte, and glued it onto 2 opposite corners. I wouldnt reccomend it on a card that is worth anything though.

Glue is a really bad conductor, I dont have any pics. I had to glue it on as it was a non-standard mounting, and nothing would fit, 440MX's dont really need a fan, but I didnt want to chance a dodgy connection to the heatsink so I left it on, it looks pretty weird.

OK thanks, I think I'll just buy a stock passively cooled card :o .

I glued a generic (but large) electronics heatsink onto my 8500le back in the day. Used the thermal paste in the middle/glue on the corners method. Worked fine for 3 years.

I'd say it's only for the adventurous, but I had no problem. Today's GPU's might be more of a challenge though (heat/area has gone up).

hmmm, I'm just waiting for someone to take a inverted-atx case, attach a crossbeam for sturdily mounting the vidcard to both sides of the case and slap a ninja on a 8800GTX :D :D

Considering that the power hunger of graphic cards is growing more than that of CPUs, I believe we can expect a new product:
An (E)ATX sized graphic card including a motherboard, the GPU socket having the same HSF mounting mechanism as the CPU one.
This could also lead to a new kind of case, that has fewer PCI slots and two 120 mm exhausts in the back, aligned and ducted to tower HSFs.

Here is my GTO2 with a modded Xeon HSF:

Basically, the main thing you must do, is properly measure your mounting holes. When you have the measurements, you can then proceed to "dry" fitting the CPU cooler to see if it does not interfere with any capacitors or such. Then simply drill and tap the holes. I would suggest using a #4-40 screws and tap.

Notice the temps:)


Good luck and do not let anyone's lack of imagination stop you,

Wow I love it. Shame the photo is of mediocre quality and bad angle :lol: . I'd be scared to drill in the board, with all the copper traces all over the place :shock: .

Usually you drill the heatsink, not the board since it often has holes in it already. :)

And if I had to guess, I think trudodyr ment his/hers post to be sarcastic. I mean, using a CPU heatsink on a graphics card? Oldest trick in the book. ;)

But what if the holes are covered by the heatsink and the heatsink is as high as the one shown above? :?

The holes are supposed to be covered by the heatsink. To complicated to explain in english in my current condition. :P Perhaps this image will help.

There was a fad a couple of years back - people putting XP heatsinks on their 9800 Pros. Just had to drill some holes, gets some nuts, bolts, and washers and voila.

And only a 5 slot cooling solution ;)

That's crazy :P . I'd be more interested in a CPU heatsink without a fan because I would have a low/mid end graphics card :wink: .

BFG FX5200 with Socket 8 heat sink. Required cutting up and drilling the heat sink a bit. But uses the standard push-pins to keep it in place. Works great!

Rather than the heatsink, I installed a A64 70mm fan on a leftover 6800 Ultra heat sink and popped it onto my wife's 6800GS...much quieter than the stock cooler and 58 degrees max under load.

I've got one of these on my powercolour radeon 9600. It's a zalman ZM-NB32K chipset heatsink.

With a little bit of airflow directed across it has worked fine for the last six months for me. The stock cooler and fan was a nightmare as it was a really whiny fan but this has helped a lot.

I was thinking of doing a mod such as this with my Radeon 9700 pro using my spare Si-97 or my stock AMD Sempron 2800+ HS.

Will the Arctic Silver Adhesive work well with this since they are relatively light heatsinks?

AS Adhesive will work fine. You might want to try a mix of 50/50 with AS Adhesive and AS3 (will probably work with AS5 as well, anyone knows for sure?) to create a slighly weaker bond. That way you can remove the heatsink later if you would want to. With 100% AS Adhesive you will probably not be able to do that.
100% AS Adhesive should be safer on the other hand, more secure.

Will it be an overkill to even consider a SI-97 on a R9700 pro? Or the heatsink is good enough to run the card fanless?

With the 9700P and good case flow, I bet you could run it passive with teh SI-97, but I would not suggest overclocking.

And to add, I would not suggest using thermal adhesive to stick the SI-97 to your card. That is just asking for trouble, in my opinion. The GPU die has a small surface area and seeing as though the SI-97 will probably be touching the PCI slots, that would mean leverage on the cooler at all times. And the suggest for diluting the adhesive works great for memory but is a dead card waiting to happen with a GPU and a heavier than stock heatsink. I suppose you could epoxy the die and the shim to the HSF to get better results, but I wouldn't try it.

Just follow this:

Here is my 9800 Pro from just last week. I will be adding some custom RAM sinks next week after school is done!! :)
