Dimension 4700 chipset

Question

I'm contemplating upgrading the heatsink on my Dimension 4700, to try and keep the system at an overall cooler temp. What chipset is the Dimension 4700? Is it even possible to fit aftermarket heatsink coolers onto a Dell system?

Thanks for the link to that tutorial. It'll come in very handy once I manage to locate a socket 915G zalman (rarer than gold, as far as I can tell) :P

Some Dimension 4700 systems had one of the fans installed backwards at the factory. The fix is easy so you should search these forums to figure out if yours is correct or not and what to do if it's backwards.

Thanks, been browsing for heatsinks, and I haven't been able to find any for the 915Express chipset. I get the feeling they're out of production now.... Any suggestions to an upgrade would be appreciated, I live in the UK by the way!

Here's a tutorial for installing a Zalman in a Dimension 8400, the installation basics should be the same,

D-4700 has an Intel 915G Express chipset.

Dell's heatsink and motherboard retention bracket are proprietary, therefore you will need to replace the retention backet, to install an aftermarket unit.

I just reversed the fan direction today ;) It's now EXTRACTING air from the case :D I'll get on the case with the zalman's bev. Always had an affinity for them, as I like my pc's to run silent. Can you give me a slightly more detailed description of what I would have to do to remove the brace?

As far as I know, power supply fans should be exhausting air from the power supply unit.  Case fans should be pushing cooler, outside air into the case.  Processor fans should be blowing air onto the heatsink.

Alright, so the 4700 runs on the 915G chipset, but that isn't the socket type.... I've narrowed it down to either the 478 or the 775 (775 being the more recent), How can I be certain of which it is?

Google for Everest Home Edition software. It used to be available, free, from its maker at www.lavalys.com but they discontinued the free version. Some websites might still have it in their archive. Everest will tell you which chipset is on the mobo along with a lot of other information about what's under the hood.
