Has anyone tried hacking a Socket-A or Socket-462 cooler to replace the default ZIF heatsink inside the BW G3's? Results? Please post them here.

You don't like Macs? Good, more for me.

Please see my post in this forum under subject "G4 temps under load". Don't have a G4 yet, but *major chronic* problems with an iMac have me looking into building a socket-A PeeCee and the available tech/cost has been a virtual eye-opener.

Can you refer me to an online source that will familiarize me with the G4 proc, socket, and mobo that Apple provides in the new G4 towers?

One of my questions is whether or not the Mac G4 mobo is pre-drilled near the socket corners as are most of the PeeCee mobos. I'm intrigued with the myriad of HSF options in the darkside - particularly CPUFX's 500 gram machined aluminum "Core" HSF which can be easily attached to the pre-drilled mobo itself using four included nylon bolts. http://www.overclockershideout.com/M...tegory_Code=HS

Is your mobo drilled and what are your current thoughts about the problems that might attend hacking a top shelf cpu cooler?

The G4 tower is designed so the P/S fan blows directly on the processor heatsink and the PCI slots (cools your extra video card and such, too). Extra cooling doesn't seem to be necessary. I have a G4 DP500 that I OC'd to 550. All I changed in the cooling was to replace the thermal tape on the processor to some high grade silver based thermal paste. Measuring with both Gauge Pro(only measures processor A) and a shareware called Thermograph(processors A&B), my processors run between 70-100 F.
I also have an old 8500 with a G3-400 OC'd to 454. Because of space constraints, i screwed 4 video-processor style fan assy's to the flat-plate heatsink(no fins)

iPad, dunno if the B&W's design is the same inside as the G4. If not, you should be able to mount a cooler to a flat plate and attach it to the processor with the existing clips.

Just found out yesterday that a company in San Diego makes an aluminum foam heatsink that is almost twice as efficient as traditional heatsinks. One of the engineers at work is doing his Master's thesis on heatsink design. He said he'll give me his sample to play with, when he's done. Will try to post more tonite.

Yes the case design is very SIMILAR, but not identical, but close enough as far as this disussion is concerned.

You can get a small square, flat CPU fan/heatsink combo at RadioShack or BestBuy for <$10.00 and either use them as is to replace the existing heatsink, or seperate them and mount the fan DIRECTLY to the top of the stock heatsink, with some sheet metal screws. Power comes from the spare HD power leads.

Works great for me w/ my G3 o'cd from 350 to 450mhz

Hey zac4mac, my school project is highly dependent on good heatsinks. Would you point me out the WWW of this San Diego company (or phone ##) and whether they are producing them yet???

Sorry about the time lag.. between a full time job and taking 8 hrs of junior level math&physics, some things don't happen right away.
The outfit I referred to is ERG Materials and Aerospace Corp. in Oakland, Ca. www.ergaerospace.com (510) 658-9785
