Thanks, that was very helpful!

I cooked something a bit louder ^^

Cover the GPU heatsink fins partially to keep air routed through the fins longer.

Cheers,

You can test your ducting mods with cardboard and masking tape to see what works well. Just use good masking tape, as the cheapy white stuff will curl up and fall off when it gets warm.

Last time I was doing things of that sort, I ended up using galvanised duct sheeting, IDK whether it was because I just had some, or I was trying to be funny, but it worked okay. I had several pairs of tin snips to make working with it easy though.

Unicorn herding operations are proceeding, but all the totes of hens teeth and barrels of rocking horse poop give them plenty of hiding spots.

Thanks for the suggestions. I'm going to tweak this duct to better fit the outlet on the bracket.
My FX can't do 500/1000 MHz even at 1.5V, I would probably have to solder the missing caps and make a GDDR2 vmod. So currently the card is modded to FX5800 non-ultra (400/800) and the highest temperature I have seen is 62C in Doom 3.

Do you want to hear how loud it is? 😉

OK, so prepare your earplugs 😉

I can't explain why I like this so much 🤣

Nice system, btw. Socket 478 and Rambus go well together.

Thank you very much for the walkthrough.
I successfully turned my Quadro FX1000 into a FX5800U

I used a Zalman VF1000 as cooler (which is compatible) and some RAM heatsinks (+ thermal glu)

The mounting holes are really close to some SMD components so i used a fiber washer around the hole.
I use electric tape to insulate the components because the Zalman screws have metal springs attached and i wanted to prevent any interaction with the components/PCB.

I glued the RAM heatsinks (mostly hidden behind the zalman cooler)

Final result :

Temperature mostly stays in the 55-60C° under heavy load (HL2 maxed @ 1920 x 1200 (16:10) )

Nice!

Watch the temp on those RAM chips in the back, the stock cooler for a 5800U is huge and gets really hot, Im afraid the ones you used may be overwhelmed.

I don't have an infrared thermometer but during the 3DMark runs and my HL2 test play i touched the back heatsinks several times and they were not that hot (less than 50° in my opinion but i'm testing on an open test bench and the proximity of the CPU cooler probably helps a bit too). Its nothing near the heat of a Voodoo3 for example (where it's painful to touch the dissipator)

I'm still considering adding a smaller fan on the back, just to be safe (like on some FX5900 from MSI)
