Until recently I've been toying around with everything from the 8088 to the Pentium 3 and not too late Athlon. Now I've got hold on a Asus P4C800-E Deluxe with 2GB ram and P3 3,4GHz CPU.

At first I've put in a Radeon 9600 and that runs great. Now lately I've got my hands on a Radeon HD 4650 AGP with a huge Zalman passive heat sink. Since I want to use that card, it's obviously that I'll pair it with the fastest AGP system I've got: the P4C800.

Now I've been reading, and it seems some people really advise to make sure the bridge is properly cooled. Is the chip in the centre of the pic below the AGP bridge?

If so, it's even more obvious that it's not being cooled. How would you suggest I'd cool it properly?

The attachment Zalman Blue Ram Sinks.jpg is no longer available

Makes sure its the blue ones, rather than the silver

Just some regular ram sinks will do? Great! I think I've got some laying around, but I'm not sure if they're the right colour.

And indeed, they have to be the same Zalman blue 😁

Yes, that's the PCI-E to AGP bridge Rialto - you're missing a heat-conducting and insulating pad https://www.ixbt.com/video2/images/agp/sapphi … with-cooler.jpg. For the most part, Rialto didn't have its own cooling (unlike HSI nVidia ) so any passive cooler will do him only good.
Just make sure you don't short-circuit the smd around the core.
